On any unix terminal emulator, enter the command:
<nowiki>
ssh <userName>@HacDC-shared-m335-1.hacdc.org
</nowiki>
On other platforms, try applications like [http://www.chiark.greenend.org.uk/~sgtatham/putty/ PuTTY] with similar settings.

=CommandReference=
Routinely important commands unique to this server documented as follows.
==Users==
===List===
List OpenVZ VMs created for you.
<nowiki>
cat ~/hovzList
</nowiki>
===Startup===
<nowiki>
sudo /usr/sbin/vzctl start <name>
</nowiki>
===Shutdown===
<nowiki>

<nowiki>
sudo /usr/sbin/vzctl enter <name>
</nowiki>

==Root (Admin)==
===hostedOpenVZ===
* ./hovzNewUser <userName> # Creates user account with default OpenVZ VM and permissions.
* ./hovzDelUser <userName> # Deletes user account, associated VMs, and associated OpenVZ permissions.
* ./hovzNewVM <userName> <VM_Number> <dist> # Creates VM accessible to non-root user <userName> .

===Autostart===
Through normal reboots, host will suspend/resume any guest VMs.
===iptables===
====Investigation====
* iptables -t nat -L -n -v #Lists port forwarding rules.
* iptables -t nat -F #Deletes port forwarding rules.
* iptables -D PREROUTING 1 #Deletes port forwarding rule.

====Forwarding====

=====Specific=====
<nowiki>
/sbin/iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 20283 -j DNAT --to 10.174.10.5:22
</nowiki>

=====Persistent=====
Package iptables-persistent has been installed. Upon installation, existing iptables rules were saved. Edit /etc/iptables/rules.v4 .

=====ReInstall=====
* Install OpenVZ, documented at http://openvz.org/Installation_on_Debian .
* Install hostedOpenVZ, documented at https://github.com/mirage335/hostedOpenVZ .
* Change default kernel in /etc/default/grub.cfg .
* Apply "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" .

=Characteristics=
* CPU - E2200 Dual-Core 2.2GHz
* RAM - 1GB
* HDD - 500GB
* Hostname - HacDC-shared-m335-1
* FQDN - HacDC-shared-m335-1.hacdc.org

=Redundancy (RAID)=
None yet, keep backups. Nonetheless, hard disk is kept cool, so the server should have a long life ahead of it.

=Policies=
==Permissions==
===Root===
HacDC members with a demonstrable need or willingness to manage non-root users may be given root access. Imperative that root users do not jeopardize uptime.
===Shell===
All HacDC members are welcome to non-root shell accounts, directly provided by the server, and used to manage OpenVZ VMs.

===OpenVZ===
All HacDC members are welcome to OpenVZ Virtual Machines. Resources, including CPU, disk space, and external network ports, will be allocated on an as-needed first-come-first-serve basis.

Root users, please use the provided hostedOpenVZ scripts. Following the naming conventions set therein helps account for which resources belong to whom.

==Notifications==
Internal server email will notify users, if feasible, on the following schedules, subject to change.
* Three days before planned downtime exceeding one hour.
* One week before planned permanent downtime (obsolescence).

==Removal==
* Three months before removal of ex-member accounts. Exceptions on a case-by-case basis.
==DataLoss==
* Users should regularly backup critical data offiste.
* Onsite data storage is not guaranteed to be reliable.
* All server data may be deleted after obsolescence.
* Removed accounts may be deleted immediately and permanently upon deactivation.
==Privacy==
Machine is physically accessible to all keyholding HacDC members. Although HacDC members are generally responsible, privacy should not be expected.
==AcceptableUse==
===Sharing===
Sharing of account resources is permitted, however, additional resources will be allocated according to individual member needs for specific purposes. As a reminder, compromised accounts will be immediately removed as discovered.
===Bandwidth===
Hard bandwidth limits have not been set to ease administration of local file servers. However, please configure applications to limit maximum bandwidth use where possible, particularly for web servers.

=Special Services=
==Funtoo==
Funtoo (enhanced Gentoo) build server is available, with binary packages and weekly full-os tarballs for new installations.

After obtaining the password for remote access, upload a key and set PORTAGE_BINHOST="ssh://binpkguser@HacDC-shared-m335-1.HacDC.org:<port>/opt/mirage335OS-x64/usr/portage/packages" .

<nowiki>
ssh-copy-id -i "./key.pub binpkguser@HacDC-shared-m335-1.HacDC.org -p <port>
</nowiki>

This also provides access to regularly generated tarball images for re/installation of a fresh OS.

DSONano white screen of death

2014-09-12T23:46:46Z

Haxwithaxe: /* Sollution */

==Problem==
DSONano v2 with DFU loader v3.26 does not work with the firmware used by the other v2 models.
The drivers for the LCD display changed so flashing the "normal" thirdparty firmware causes an all white screen to persist on the screen. In some cases it flickers as well.

==Sollution==
# use the patched firmware provided [http://www.seeedstudio.com/forum/viewtopic.php?f=22&t=4823&sid=3e537c759d444eb3ae50c74adf5fc1eb&start=40 here] and mirrored [[Media:BenF_P2-3.64APP_3.53LIB_LCD_patched_v2.hex|here]]
===flashing===
# plug the dsonano in via usb
# press the down arrow and power on the device
# mount the block device (/dev/sdX, no number)
# copy the .hex file to the mount point
# wait for it to dissappear
# unmount the mount point
# mount the new block device
# check to see that the extension on the file now reads .RDY (limited file name length truncates the rest of the name sometimes)
# powercycle to check if it worked

== Recognition ==
* Dan Barlow - Identifying and obtaining better laser tube.
* Julia "juri" Longtin - Bringing much needed funding to HacDC equipment.

== Director Reports ==
=== President's Report ===

=== Vice President's Report ===
==== Admin Team ====
* CAT6 has been run for several things around the space.
*** 3D printer station machine (the cube is directly under the switch so we didn't run one for that)
*** Laser and laser station machine
*** CNC station machine
*** Clear modem (we have a plan for load alancing between the church and clear within the space)
*** Ham Desk (includes remote access for the wifi gear on the roof)
** There will be more but we know these things will be on the wired network so we ran cables for them. They are not mounted because we had a miscommunication about the available mounting options. We want for it to be in conduit but we were hoping to do that when the AC electrical is upgraded to coordinate the conduit selection. We didn't have a chance to crimp them all before leaving. Feel free to crimp (type A wire order) and test them tonight. There is a diagram on the crimper and we have ezcrimp terminators. El Presidente can give access to those materials which are on lone from ITechGeek.
** If you want network ports anywhere in particular in the space, email [mailto:admin+icanhazjack@hacdc.org?subject=icanhazjack admin+icanhazjack@hacdc.org] and we'll take those requests into account when we run more cables.
* We have one of the switches donated by Ahmed on the second to top shelf of the set over the main workbench in the workroom. Please try to not unplug it for too long or unplug any network cables from it. It is a smart switch and the ports in use are mapped to VLANs some of those VLANs are setup to restrict access to various things (like the mesh and ham radios from the the greater church network). The other switch donated by Ahmed is in the network closet of the church and is the switch distributing internet to the rest of the church.
* There is another gigabit smart switch we wanted to put in the basement for servers down there. It is currently MIA and help finding it would be appreciated. It is a dark blue, half depth rackmount, Trednet or Netgear. If you know where it went or where in the basement it got too please email [mailto:admin@hacdc.org?subject=found%20network%20switch admin@hacdc.org].

=== Treasurer's Report ===
Here is the financial summary spreadsheet for August 2014: [[File:HacDC Financials 2014 08.pdf]]. We gained Celeste, Enrique, and Phillip as new members. We lost Ruben Duque, Elizabeth Smith, Dan Koestler, and Bjorn Westergard. We have 44 dues-paying members in good standing, 7 dues-waived members, and 2 members who are behind on dues.

==== Project Awesome ====
Here is the Project Awesome spreadsheet for August: [[File:HacDC PA Projects-2014 08.pdf]]. We continue to have to dip into savings to pay our rent, so no dividend this month. :(

=== Secretary's Report ===
I purchased a house this past Wednesday, so I'm busy and not at HacDC tonight.

I updated the members@ list with the latest regarding the Hac<b>k</b>DC situation. I will continue to pursue this issue as discussed with the rest of BoD.

The OpenPGP Card group order has arrived. I will bring the cards/readers to the Cryptoparty for people to collect their share. If you need it sooner, you'll need to schedule with me.

I have new signs for the bathrooms, but since I haven't been to the space in over two weeks I haven't had a chance to put them up. Next time I'm there I'll get them installed.

I also made ten copies of the space key, because we ran out last month, but as I haven't been to the space they're not in the BoD locker yet.

While I'm buying stuff for my house, I'll also pick up a replacement door handle for the pirate bathroom.

If there's anything else, you can call me up, but my phone currently gets no service in my new basement so don't be offended if I don't pick up, it probably means my phone didn't ring.

=== Director-at-Large Reports ===

== [[:Category:Project_Awesome|Project Awesome]] Reports ==
=== Project LASER ===

=== Project BYZANTIUM ===
We basically blew off yet another sprint last month because I was busy with the Crab-B-Q. (By the way, you can totally cook crabs in a smoker.)

We are slacking and we really need to pull it together soon. I'm just having trouble making time for things.

=== Project KITBUILD ===

=== Project SUPPLIES ===
Have a ~$50 receipt for various screws purchased from Fastenal, mostly for the optical table.

=== Project EXPANSION ===
For lack of incoming funding, the project coordinator (mirage335) feels that any purchase made from these funds must be well planned.

=== Project SPACECAM ===

== Member Reports ==
=== mirage335 ===
[[File:OpticalTableRobot.png|400px|right]]
Finally designed the [[OpticalTableRobot]]. Similar to the FlexReplicator, supports multiple tools simultaneously. However, this platform is far more rigid (absolute accuracy expected to be <2um across the ~8'x4' work area). Surprisingly, it is also cheaper than a FlexReplicator, thanks to the free table and extrusions.

Julia Longtin has successfully sought investors, and plans to use the robot to manufacture large car parts.

[[Regular Member Meeting 2014 02 11]]

== Recognition ==
* Thanks to Evan and Zack for their work on the laser cutter.
* Everyone involved in Project SEM .
* David McInnis for adding really cool lighting to the new shelves in the basement.
* Julia Longtin (aka. juri) for more 3D printer tweaking and getting ahead on cleaning up the space.

== Director Reports ==

=== President's Report ===

As reported last month, the BoD has approved accepting the donation of a Scanning Electron Microscope (SEM). The SEM is now ready to be picked up and we have about three weeks to collect it. It is currently in Norfolk, VA and is a large, heavy piece of equipment. We will need to rent/borrow a truck (ideally one with a lift-gate) to transport it up to HacDC, and we'll need several strong volunteers to help us load, and unload the truck (including bringing it up the stairs and into the workshop). Additionally, we will need some help making space for it in the workshop. We are currently shooting for Saturday, March 29th.

=== Vice President's Report ===

admin team is accepting donations of gigabit network switches. we need both managed and unmanaged switches. one managed switch with 20+ ports which is for the church network.
we are getting the space wired for gigabit ethernet so cat5e and cat6 keystone jacks and and wall plates are welcome.

=== Treasurer's Report ===

Here is the financial summary spreadsheet for February 2014: [[File:HacDC_Financials_2014_02.pdf]]. We gained two members in the last month: Elizabeth Smith and Ariam Mogos. We lost two members in the last month: Tim Dixon and Nick Mapsy. We have 46 dues-paying members in good standing, two permanently dues-waived members, four temporarily dues-waived members, and five members who are behind on dues.

==== Project Awesome ====

Here is the Project Awesome spreadsheet for February: [[File:HacDC_PA_Projects-2014_02.pdf]]. Once again we are in the red for the month, so there is no Project Awesome dividend. :(

=== Secretary's Report ===
NonHacDC calendar is being populated. Need to put it in a more public place and open it up to members for editing.
Otherwise nothing significant to report.

===Procedures===

===Donations===
If you would like to donate items to HacDC please email bod@hacdc.org and we can help you decide what to donate and if needed where things that we can't take can go.
When the donation arrives at the space each item should be labeled with a date of arrival and put where it belongs. A member can help you find where that is.

====Give Aways====
If you would like to just give away free stuff please label each item with the date it entered HacDC and that it is a "Give Away" so we can dispose of them if no one wants them after a (currently unspecified) amount of time.

=== Treasurer's Report ===
Here is the financial summary spreadsheet for December 2013: [[File:HacDC Financials 2013 12.pdf]]. One prospective member (not yet voted in) has started paying dues. Longtime member and generous contributor Tim Collins has resigned his membership. Several members haven't paid their dues for a couple of months, and since they've been unresponsive over e-mail it's unclear whether they intend to resign.

==== Project Awesome ====
Here is the Project Awesome spreadsheet for December: [[File:HacDC PA Projects-2013 12.pdf]]. I'm able to declare a $200 dividend and add $132.29 to our un-earmarked reserves. There were 16 votes, unchanged from the previous month.

=== Secretary's Report ===
Reduced wiki users from ~140k to 1.1k (bots, bots, and damned bots).
Verified that all wiki software is updated.

* Want to focus on HacDC's calendar.. meaning, if you know of something interesting happening, send it to mailto:secretary@hacdc.org

=== Project LASER ===

=== Project BYZANTIUM ===
* We are currently scattered all across North America.
* We have joined a group working on disaster relief networking with a focus on delay tolerant tools for identifying casualties and missing people. The group consists of people from commotion wireless and a few other projects, and has been organized by Geeks Without Bounds.

=== Project KITBUILD ===

No planned kit builds but gearing up to have one in the Spring. Work is too damn high, until then. - Alberto

=== Project SUPPLIES ===
Healthy and stable at ~$1.4k.
====Recent Purchases====
* Glass sheets for Prusa Mendel.

=== Project EXPANSION ===
Only $145 after two months. At this rate, it will take another three months to buy a vertical bandsaw.

If you are holding one of the 3.783 votes for SUPPLIES, '''please consider voting for EXPANSION instead'''.

=== Project SPACECAM ===

== Member Reports ==
=== mirage335 ===
==== Prusa Mendel 3D Printer ====
Finally, the machine is stable, reliable, and producing high quality results, down to '''75 microns'''. Improvements include:
* Solid aluminum groovemount bracket, CNC milled at HacDC, unlikely to degrade.
* Print bed stackup documented at http://wiki.hacdc.org/index.php?title=PrusaMendel_Print_Surface .
* Vastly improved Slic3r settings.
* Spare parts. If it isn't over-engineered, we probably have multiple spares.

No further downtime is expected.

==== Photolithography PCB Fab ====
Have literally attempted every reasonable PCB fab technique, including etching spraypaint with our CO2 laser cutter, laser-printer toner transfer, scribing spraypaint with the CNC mill, and finally photolithography.
At this point, the chemical process has been fully tested with excellent results, we just need a better printer for higher-quality photomasks.

[[File:Photoresist.jpg|200px]]

Exposed and developed photoresist. Note the rather solid bare/resist regions. Fused lines are due to printed photomask quality.

[[File:Copper.jpg|200px]]

Chemically etched copper. Note the high-quality edges on the large pads. Uneven and lost traces are due to manual cleanup attempt.

==== HacDC UV Laser Cutter ====
The CO2 laser cutter does not add any particularly novel functionality to HacDC. Lacking precision, it is only useful where a shopbot would likely be more versatile.

To bring higher-resolution laser cutting to HacDC, a UV 405nm laser has been strapped to our CNC mill. Unfortunately, this laser is estimated at <100mW, limited to cutting thin, dark paper. Using a 2W laser like [http://www.ebay.com/itm/2W-445nm-M140-Blue-Laser-Diode-in-Copper-Module-W-Leads-Three-Element-Glass-/170892986250?pt=LH_DefaultDomain_0&hash=item27ca04078a this one for $70] would allow us to laser spraypaint off circuit boards for etching, cut high-quality soldermasks, scribe fine-pitch text, etc.

Of course, a 2W UV laser raises some safety concerns, so only trained individuals should use that with the appropriate safety equipment (just like any other laser cutter).

==== MiniVNA Extender ====
Thanks to haxwithaxe confirming the order, we now have an 1.5GHz extender for our vector network analyzer en route. This enables UHF antenna testing, transmission line testing, mid-range capacitor/inductor parasitic testing, and more.

==== Projector/OpenDisplay ====
Have 3 giant fresnel lenses from old projection TVs. If we can use the badly scratched Fresnel upstairs out-of-focus in the light gathering optics, '''we only need one more of these lenses''' from old projection TVs on [http://washingtondc.craigslist.org/search/zip?query=projection&zoomToPosting=&srchType=A&minAsk=&maxAsk= craigslist].

Also, a modular pallet-and-rail will be used for the optics this time. The prototype frame that has been taking up space in the workshop is no longer useful, and was disassembled for that reason.

==== Flex Replicator ====
Multi-tool desktop factory platform. CNC Mill, Laser Cutter, 3D printer, and more, all simultaneously.

Design mechanically complete. MDF print surface will be added, along with brackets and laser-safety walls. Should be able to build one of my own within the month.

[[File:FlexReplicatorRender.png|200px]]

Open-source, hosted on [https://github.com/mirage335/FlexReplicator github] .

==== Optical Table CNC ====
We have been recently donated about $1k worth of large aluminum extrusions. We now have the resources to build full gantry on the Optical Table at minimal expense. Soon as that Optical Table is on its feet, will outfit it with a variety of milling/extruding/lasering tools. Similar to the Flex Replicator, but '''much larger at 8' x 4' , and likely accurate to 0.5 microns'''.

We should then be able to make large wood frames, print hundreds of objects in a week, etc.

'''This is urgently stalled by the HacDC cleanup. Lack of a large area CNC has recently cost at least 150 hours of my time at HacDC while maintaining 3D printer and laser cutter, and more projects are waiting. '''

==== Biohacking ====
===== Imagnus =====
We have a really cool product. While we would prefer not to tip off any competition as all of the exact mechanisms behind it, the system does work, and we are prepared for even more in the next few weeks.

Stay tuned!

===== Biosignal Amplifier =====
BiosignalProcessor host/driver software under development, hosted on [https://github.com/mirage335/BiosignalProcessor github] . Help welcome.

[http://mirage335.dyndns.org/wiki/Category:SigBlockly#Progress SigBlockly] has been released. This graphical programming environment eases C development for signal processing and control systems tasks.

[https://github.com/mirage335/C_CMake_Template C_CMake_Template] has been released, to ease development for new C software projects.

Host driver software is therefore nearly finished. Once libsndfile has been integrated properly, users will have an ultra-high-performance two-channel 'plug-and-play' USB ECG/EMG/EEG.

===== Thursday Meetings =====
The Thursday biohacking meetings have been getting quiet, but the core members still occasionally drop by and express interest. With the biosignal amplifier nearly finished, and hopefully more tools deployed at HacDC, we should be able to resume other projects.

==== Basement Shelves & Cleanup ====
Members are encouraged to discuss floor plan options with mirage335 after the meeting.

Personally, mirage335 has invested a lot into expanding HacDC capabilities, and doesn't see the following as particularly beneficial to those efforts:
# Cutting down the new shelves without first providing an adequate alternative.
# Unduly bureaucratizing new materials or equipment at HacDC.

Feel free to skim over the rest of this section during the meeting.

===== The Debate =====
Despite a full CAD model, lengthy comment period, and general consensus that the shelves should be built, all well in advance of their construction, suggestions have emerged to cut down the new shelves, among other things.

Please consider:

# If the shelves were not built, we would still be doing nothing effective about lack of storage, cleanup, or equipment workstations, probably for several more years.
# Cutting down the new shelves could delay cleanup and equipment workstations more months and years. Every project risks non-completion.
# Alternative uses for the basement are going nowhere at that rate anyway.
# Smaller shelves will not give us any unused storage space, leaving no room for growth.

Also, it is worth noting:
# AFAIK, HacDC is paying very little rent for that basement, among other things I might say on that point.
# About $300 and four person-days of effort have gone into the shelves. Jeopardizing that needs something to show for doing so.
# Those who want something dramatically different can build it, demonstrate that it works, and THEN propose removal of older solutions.
# Personally, I have put in at least several hundred hours cleaning up the space as well as maintaining HacDC's 3D printer and laser cutter. At least half that time was wasted due to lack of maneuvering room, a problem these shelves are needed to solve.

On the positive side, there are some more reasonable ways to address concerns raised in the debate, outlined below. Also, next time I propose something like this (if ever...), dimensions will be included in the render image.

===== Wheels =====
At a cost of approximately $43.17, we can add wheels to the shelves capable of supporting 1.6 metric tons. Additional wheels or fixed supports can be fitted later.

https://raw.github.com/mirage335/OpenBuildings/master/Units/Shelves/Render.png

Since some concerns have been raised about placing more than a metric ton on wheels, this should probably be done only if members absolutely insist on pushing the shelves against a wall.

===== Floor Plans =====
https://github.com/HacDC/FloorPlan/raw/master/FloorPlans/BasementBackRoom/BasementBackRoom_ShelvesAsideLeft.pdf

Floor plans are still in progress, derived from the Solidworks 3D models published on [https://github.com/HacDC/FloorPlan github]. Other members are invited to explore alternative layouts using these files.

Also, the tables and carts modeled are not only speculative, but intended to be shared with both rooms in the basement. At any time, members could push the carts out of whichever room is most in use, or perhaps even temporarily outside.

===== Policy Changes =====
Some have objected to HacDC storing anything at all, and others have proposed unduly bureaucratic processes. While this probably is not a growth-oriented viewpoint, the need for a more effective, well publicized disposal policy, may be. I have been attempting help out by drafting such a policy.

[[ExcessDisposal]]

Features include:
* Specific "Stays at HacDC Criteria" with time limits.
* Going-out-pile and rotation processes.
* Disposal processes.
* Conflict resolution (BOD approval).

However, since there is still a lot of debate over this policy, I suggest it not be voted on yet.

==== Occupancy Sensor ====
The hardware and firmware at HacDC are still working, but eryc's server no longer is. We need a new server to accept and publish the data.

In the long term, a [https://github.com/mirage335/EasyPLC new occupancy sensor based on the raspberry pi] will replace the existing system

==== WYSE Terminals ====
Created persistent USB stick image for the WYSE terminals, documented at [[Linux_on_Wyse_Winterm_S10_Thin_Clients]]. Trick is to use an old version of syslinux.

Tested about two dozen units. Surprisingly, all are functional, capable of USB and presumably PXE booting.

Request the additional 30 units mentioned by David Whiteis make it to HacDC. Planning to deploy these at HacDC as thin clients for a high-end server.

==== myDAQ and myDSP ====
Special thanks to Ahmed Aden for making a special trip to bring the myDAQ and myDSP back to us.

== Old Business ==

=== From [[Regular Member Meeting 2013 12 10|December agenda]] ===
* Zach purchased materials for basement shelves, and should now be reimbursed up to $400 (exact receipt value is not known to mirage335).
* Approving another $75 will allow wheels to be added to the shelves. That is not to say the wheels will be added just because their budget was approved.
* Katie proposes we allocate $100 for our traditional holiday gift to the security guard. Update (Dec. 22): ITG has provided the $100 gift to the guard; this proposal includes reimbursing him.

=== Shelves ===
$600 for shelves to mirage.
* Quorum not met, could not vote.

=== Treasurer's Report ===
Here is the financial summary spreadsheet for December 2013: [[File:HacDC Financials 2013 12.pdf]]. One prospective member (not yet voted in) has started paying dues. Longtime member and generous contributor Tim Collins has resigned his membership. Several members haven't paid their dues for a couple of months, and since they've been unresponsive over e-mail it's unclear whether they intend to resign.

==== Project Awesome ====
Here is the Project Awesome spreadsheet for December: [[File:HacDC PA Projects-2013 12.pdf]]. I'm able to declare a $200 dividend and add $132.29 to our un-earmarked reserves. There were 16 votes, unchanged from the previous month.

=== Secretary's Report ===
Reduced wiki users from ~140k to 1.1k (bots, bots, and damned bots).
Verified that all wiki software is updated.

* Want to focus on HacDC's calendar.. meaning, if you know of something interesting happening, send it to mailto:secretary@hacdc.org

If you are holding one of the 3.783 votes for SUPPLIES, '''please consider voting for EXPANSION instead'''.

=== Project SPACECAM ===

== Member Reports ==
=== mirage335 ===
==== Prusa Mendel 3D Printer ====
Finally, the machine is stable, reliable, and producing high quality results, down to '''75 microns'''. Improvements include:
* Solid aluminum groovemount bracket, CNC milled at HacDC, unlikely to degrade.
* Print bed stackup documented at http://wiki.hacdc.org/index.php?title=PrusaMendel_Print_Surface .
* Vastly improved Slic3r settings.
* Spare parts. If it isn't over-engineered, we probably have multiple spares.

No further downtime is expected.

==== Photolithography PCB Fab ====
Have literally attempted every reasonable PCB fab technique, including etching spraypaint with our CO2 laser cutter, laser-printer toner transfer, scribing spraypaint with the CNC mill, and finally photolithography.
At this point, the chemical process has been fully tested with excellent results, we just need a better printer for higher-quality photomasks.

[[File:Photoresist.jpg|200px]]

Exposed and developed photoresist. Note the rather solid bare/resist regions. Fused lines are due to printed photomask quality.

[[File:Copper.jpg|200px]]

Chemically etched copper. Note the high-quality edges on the large pads. Uneven and lost traces are due to manual cleanup attempt.

==== HacDC UV Laser Cutter ====
The CO2 laser cutter does not add any particularly novel functionality to HacDC. Lacking precision, it is only useful where a shopbot would likely be more versatile.

To bring higher-resolution laser cutting to HacDC, a UV 405nm laser has been strapped to our CNC mill. Unfortunately, this laser is estimated at <100mW, limited to cutting thin, dark paper. Using a 2W laser like [http://www.ebay.com/itm/2W-445nm-M140-Blue-Laser-Diode-in-Copper-Module-W-Leads-Three-Element-Glass-/170892986250?pt=LH_DefaultDomain_0&hash=item27ca04078a this one for $70] would allow us to laser spraypaint off circuit boards for etching, cut high-quality soldermasks, scribe fine-pitch text, etc.

Of course, a 2W UV laser raises some safety concerns, so only trained individuals should use that with the appropriate safety equipment (just like any other laser cutter).

==== MiniVNA Extender ====
Thanks to haxwithaxe confirming the order, we now have an 1.5GHz extender for our vector network analyzer en route. This enables UHF antenna testing, transmission line testing, mid-range capacitor/inductor parasitic testing, and more.

==== Projector/OpenDisplay ====
Have 3 giant fresnel lenses from old projection TVs. If we can use the badly scratched Fresnel upstairs out-of-focus in the light gathering optics, '''we only need one more of these lenses''' from old projection TVs on [http://washingtondc.craigslist.org/search/zip?query=projection&zoomToPosting=&srchType=A&minAsk=&maxAsk= craigslist].

Also, a modular pallet-and-rail will be used for the optics this time. The prototype frame that has been taking up space in the workshop is no longer useful, and was disassembled for that reason.

==== Flex Replicator ====
Multi-tool desktop factory platform. CNC Mill, Laser Cutter, 3D printer, and more, all simultaneously.

Design mechanically complete. MDF print surface will be added, along with brackets and laser-safety walls. Should be able to build one of my own within the month.

[[File:FlexReplicatorRender.png|200px]]

Open-source, hosted on [https://github.com/mirage335/FlexReplicator github] .

==== Optical Table CNC ====
We have been recently donated about $1k worth of large aluminum extrusions. We now have the resources to build full gantry on the Optical Table at minimal expense. Soon as that Optical Table is on its feet, will outfit it with a variety of milling/extruding/lasering tools. Similar to the Flex Replicator, but '''much larger at 8' x 4' , and likely accurate to 0.5 microns'''.

We should then be able to make large wood frames, print hundreds of objects in a week, etc.

'''This is urgently stalled by the HacDC cleanup. Lack of a large area CNC has recently cost at least 150 hours of my time at HacDC while maintaining 3D printer and laser cutter, and more projects are waiting. '''

==== Biohacking ====
===== Imagnus =====
We have a really cool product. While we would prefer not to tip off any competition as all of the exact mechanisms behind it, the system does work, and we are prepared for even more in the next few weeks.

Stay tuned!

===== Biosignal Amplifier =====
BiosignalProcessor host/driver software under development, hosted on [https://github.com/mirage335/BiosignalProcessor github] . Help welcome.

[http://mirage335.dyndns.org/wiki/Category:SigBlockly#Progress SigBlockly] has been released. This graphical programming environment eases C development for signal processing and control systems tasks.

[https://github.com/mirage335/C_CMake_Template C_CMake_Template] has been released, to ease development for new C software projects.

Host driver software is therefore nearly finished. Once libsndfile has been integrated properly, users will have an ultra-high-performance two-channel 'plug-and-play' USB ECG/EMG/EEG.

===== Thursday Meetings =====
The Thursday biohacking meetings have been getting quiet, but the core members still occasionally drop by and express interest. With the biosignal amplifier nearly finished, and hopefully more tools deployed at HacDC, we should be able to resume other projects.

==== Basement Shelves & Cleanup ====
Members are encouraged to discuss floor plan options with mirage335 after the meeting.

Personally, mirage335 has invested a lot into expanding HacDC capabilities, and doesn't see the following as particularly beneficial to those efforts:
# Cutting down the new shelves without first providing an adequate alternative.
# Unduly bureaucratizing new materials or equipment at HacDC.

Feel free to skim over the rest of this section during the meeting.

===== The Debate =====
Despite a full CAD model, lengthy comment period, and general consensus that the shelves should be built, all well in advance of their construction, suggestions have emerged to cut down the new shelves, among other things.

Please consider:

# If the shelves were not built, we would still be doing nothing effective about lack of storage, cleanup, or equipment workstations, probably for several more years.
# Cutting down the new shelves could delay cleanup and equipment workstations more months and years. Every project risks non-completion.
# Alternative uses for the basement are going nowhere at that rate anyway.
# Smaller shelves will not give us any unused storage space, leaving no room for growth.

Also, it is worth noting:
# AFAIK, HacDC is paying very little rent for that basement, among other things I might say on that point.
# About $300 and four person-days of effort have gone into the shelves. Jeopardizing that needs something to show for doing so.
# Those who want something dramatically different can build it, demonstrate that it works, and THEN propose removal of older solutions.
# Personally, I have put in at least several hundred hours cleaning up the space as well as maintaining HacDC's 3D printer and laser cutter. At least half that time was wasted due to lack of maneuvering room, a problem these shelves are needed to solve.

On the positive side, there are some more reasonable ways to address concerns raised in the debate, outlined below. Also, next time I propose something like this (if ever...), dimensions will be included in the render image.

===== Wheels =====
At a cost of approximately $43.17, we can add wheels to the shelves capable of supporting 1.6 metric tons. Additional wheels or fixed supports can be fitted later.

https://raw.github.com/mirage335/OpenBuildings/master/Units/Shelves/Render.png

Since some concerns have been raised about placing more than a metric ton on wheels, this should probably be done only if members absolutely insist on pushing the shelves against a wall.

===== Floor Plans =====
https://github.com/HacDC/FloorPlan/raw/master/FloorPlans/BasementBackRoom/BasementBackRoom_ShelvesAsideLeft.pdf

Floor plans are still in progress, derived from the Solidworks 3D models published on [https://github.com/HacDC/FloorPlan github]. Other members are invited to explore alternative layouts using these files.

Also, the tables and carts modeled are not only speculative, but intended to be shared with both rooms in the basement. At any time, members could push the carts out of whichever room is most in use, or perhaps even temporarily outside.

===== Policy Changes =====
Some have objected to HacDC storing anything at all, and others have proposed unduly bureaucratic processes. While this probably is not a growth-oriented viewpoint, the need for a more effective, well publicized disposal policy, may be. I have been attempting help out by drafting such a policy.

Haxwithaxe: /* Anonimity/Privacy? */ adding explanations of anonymity and privacy in this context.

{{TOCright}}

"They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
-Benjamin Franklin, Franklin's Contributions to the Conference on February 17 (III) Fri, Feb 17, 1775 (http://www.ushistory.org/franklin/quotable/singlehtml.htm)

= Anonymity/Privacy? =
Q: What is anonymity?
A: In the context of security anonymity refers to the inability of unauthorized parties to link communications to your "real" identiy in whatever for that may take. This can also work on a sliding scale such as "Can my <crazy stalker/local law enforcement/federal law enforcement> find me?". The answer of yes for the "crazy stalker" will be significantly easier to achieve than the yes for "federal law enforcement".
Q: What is privacy?
A: Privacy is the ability to expose your information or behavior to only those parties you wish to share it with. This does not inherently include the ability to obscure your identity.

Anonymity and privacy are complementary to each other in many cases but are not mutually inclusive.

HAM HT Baofeng UV-3R

2013-10-24T16:35:38Z

Haxwithaxe: /* Recommended Modifications */

==Overview==
The UV-3R family of radios are dirt cheap 2W handheld transceivers with reasonably good stock features especially given the price. They can be very easily modified to take advantage of the on board MCU and crappy programming of that MCU.
The UV-3Rs are software controlled radios (not SDRs) the DSP isn't controllable beyond squelch thresholds (afaik) which means only when and where to transmit and receive not any changes to modulation or demodulation.

==Links==

====Firmware====
* [http://www.liorelazary.com/index.php?option=com_content&view=article&id=51:hacking-the-uv3r&catid=14:baofeng-uv5r&Itemid=17 FOSS Firmware]
** pads can be fragile or lift off easily. [[User:haxwithaxe]] recommends using a nonsolder based means of connection.
** code: [https://github.com/lelazary/UV3RMod on github]
** feature set beyond stock firmware as of 2013/04/08 noonish [https://github.com/lelazary/UV3RMod/blob/master/WISHLIST ripped from WISHLIST on github]
*** Quick interface to program rx freq, tx freq, power and PL code very quickly for repeaters. No offset, you just start with the rx freq and shift it by whichever amount you want. This will allow allow you to turn off the tx, or operate satellites. At any point during this mode, you can hold the mem channel and it will ask you which number you want to save this to.
*** Memory mode will allow you to go through your saved memory. At any point you can press menu and change more details about the channel. The details will include power with granular level, DTMF TX/RX, and other functions TBD. This mode will show the channel name and the freq underneath it.
*** Satellite Mode: Auto tuning of the frequency with response to the Doppler shift.
*** (not yet) Digital mode. Hopefully I could add some text base digital data for rx and tx. You might need to tx the text using morse code since there is no alpha numeric keypad on the radio. The digital mode will also include a store and repeat message forwarding.
*** (mostly implemented) Computer mode: All the functions of the radio including the RDA1846 registers, TX, and RX will be controlled through the serial port on the radio.
*** Fox/Hunt mode. Can be used to transmit a signal intermittently (like call sign morse code). Or send the RSSI signal into the audio, and with a directional antenna you can go hunting.
*** (not yet) Advance mode: Any RDA 1846 register can be set manually and saved for during startup.
*** (not yet) If the digital mode works, then RF programming of the radio. This will allow anyone to send you repeater information from their memory locations. I will work by selecting a memory channel to rx, and pressing a button. Then on another radio you can send the programming info.
*** (not yet) APRS mode: Boots straight to 144.39 mhz (or whatever you set it to), doesn't accept inputs, stays on the set frequency.

====Hardware====

** [http://groups.yahoo.com/group/UV-3R/message/4036 very low, low power]

====Recommended Modifications====
* fix harmonics (needs links)
* fixes as needed: speaker volume, [[HAM_HT_Baofeng_UV-3R_Mic-Volume|mic volume]], super-low low-power (needs links)

==Notes==
* '''DON'T BUY THE PROGRAMMING CABLE''' you can use a 3.5mm stereo plug and a usb to serial device. (pinouts available [http://uv3r.com/ here])
* If you buy one the only working setup for using the manufacturer's programming software found by [[User:haxwithaxe]] has been Windows7 with '''Vista''' drivers for the Prolific serial adapter.
** others have had success with WINE and in XP but since many of the cables have counterfeit controllers they have varying levels of functionality with different drivers.
** [[User:haxwithaxe]] used a VirtualBox VM with usb pass through.

===Recommended Accessories===
* A wide based flush fit BNC (or similarly durable connector) adapter (sometimes called an antenna saver) given the short mating cycle "SMA connectors are rated for up to 500 mating cycles" [https://en.wikipedia.org/wiki/SMA_connector citation via Wikipedia]
** example: [http://thumbs4.ebaystatic.com/m/mUgb7YRjFqInb9GoQZVkQMw/140.jpg SMA Male to BNC Female Connector]
** Also you can replace the adapter much more easily than the SMA connection in the radio.
** You can even apply some threadlock (the light duty stuff) to the threaded part and still keep the groundplane continuity because of the wide base on the adapter touching the rim of the SMA socket.
* Get a dedicated antenna for the VHF and UHF (or whichever you will use the most). The dedicated antennas will do wonders for performance as the stock antenna is really pretty horrible and multiband antennas in general can only be so good on any given band they are tuned for before the others suffer, so they end up being okay at best on all of them. If you followed the above then get a BNC terminated antenna and don't worry about adapters for the antennas.

==Hardware Versions==
There are a large number of internally identical radios with very nonstandardized names in the UV-3R and UV-5R family.
* UV-3R is the first iteration of the UV-3R series it is it's own beast for the most part
** Mostly-clones UV-100 and UV-200
* UV-3R MKII is the next oldest and has several variants
** UV-X4 - Just a rename for marketing?
** UV-3R+ (aka UV-3R Plus or UV-3R + Plus)
*** different battery and charging method - has an actual charging cradle but battery type is not common
*** different audio jacks (separate speaker and mic/ptt)
*** female instead of male SMA (not RP-SMA)

==Types==
There are several things that can cause built in mic sensitivity to be inadequate.
* some batches have mic gain that is too high caused by poorly adjusted trim pots
* some have it too low due to the same reason
* some have something wrong in the MCU that keeps the gain too low
* some have misaligned case isolation bushing that cover the pin prick mic hole in the case

==Bushing/Case Fix==
# invoke your inner caveman
# remove the front panel of the case
# widen the mic hole in the front panel to ~2mm or 3mm (a pocket knife does fine)
# reassemble and test. if it works well stop here else keep going
# remove the front case panel and remove the rubber boot over the electrilet mic.
# use a knife or a hole punch to widen the hole without removing the entire flat face (which is there to help reduce vibrations in the case from getting to the mic).
# reassemble and test if it didn't work it is probably something else or a combination of this and something else.

ISC Grant is completed. See Project Byzantium report.

Silver Spring Mini Maker Faire is coming up. Please plan to attend and show off what you're working on.

Speaking of Faires, it's Renn Fest season.

What's going on with the Crypto Party? Can we get that on the calendar and start promoting?

=== Vice President's Report ===

=== Treasurer's Report ===

Here is the financial summary spreadsheet for August 2013: [[File:HacDC Financials 2013 08.pdf]]. We gained Ann Millspaugh, Evan Phillips, Jarett DeAngelis, Kay Kenworthy, Brendan Levy, as new, paying members. No members left, though one will be on hiatus until January.

==== Project Awesome ====

Thanks to fewer delinquent members and an unexpected grant from the Community Foundation for Northern Virginia, we had a healthy surplus this month, so I am declaring a $1000 Project Awesome dividend, which leaves us with $1,481.74 to add to our unearmarked reserves. Here is the Project Awesome spreadsheet for August: [[File:HacDC PA Projects-2013 08.pdf]]. There are currently 15 votes.

====Arrivals====
=====IGBTs=====
* Credit to Dan Barlow, $300 parts obtained for $18, amazing find!
* 600V, 200A, ~1MHz switching speed.
* Stored in blue bucket on parts store shelves. Recommended donation of at least $100, prefer to see them used in equipment available to HacDC members.
=====PLA Solvent (Tetrahydrofuran)=====
* Manually polish or glue PLA printed parts with just few drops.
* Small glass bottle, stored inside metal tin on chemical shelf.
* Generally safe as acetone. However, seal tight to minimize oxidization, and wear nitrile gloves.
=====Solder Paste=====
* Professional quality SMT soldering by the thousand. Recommend laser cutting blue tape for stencils and hot air gun for soldering. See http://www.youtube.com/watch?v=qyDRHI4YeMI .
* Stored in fridge, ideally at 10C, for vastly extended shelf life. Not food.
* Toxic, like all solder dust. Minimize contamination, wash hands thoroughly after use.
=====PCB Milling Bit=====
* Maximum quality circuit boards, 5 mil diameter.
* Stored in toolbox.
* Tough when spinning, fragile when not.
====Future Plans====
* Spare hot-end for Prusa Mendel.
* Large plastic buckets.

Hope my reports aren't getting too long...
====General Use Computer====
New computer in front room set up for general web browsing, google hangout hosting, etc.
====Biohacking====
=====Imagnus=====
Still going well, still plan to give details later.
=====Biosignal Amplifier=====
New headgear tested, using earplug "sponges" instead of pin headers. Comfortable, works well, even through thick hair.
====Shelves====
Would like to have more shelves at HacDC. We are now accumulating considerable quantities of non-junk on floors, such as:
* Working computers, monitors, photo frames networking gear, WiFi antennas, etc.
* Stationery, CDs, floppies.
* Books.
* Laser/Mill stock.
* Microscopes, lasers, lenses, slides, etc.
* Audio gear.
* Radios.

====Projector/OpenDisplay====
====='''Giant Fresnel Lenses - Craiglist Expedition for Rear Projection TV'''=====
http://washingtondc.craigslist.org/search/zip?query=projection&zoomToPosting=&srchType=A&minAsk=&maxAsk=

'''Calling any volunteers to pick up five of these, and deliver them to HacDC for tear-down.'''

Rear projection TVs, available freely on Craigslist, are now the only known source of the five Fresnel lenses we require. Project is stalled until we get these lenses.

=====Final Cost Estimate=====
$128.97
Includes metal-halide light source, projection lens, and condenser lenses. Does not include LCD (which we probably have) or Fresnel lenses (which we probably can't buy).
=====Design/OpenSource=====
Optical experiments and design complete. Published, with CAD models, as OpenDisplay.
