Ewaldo: USRP1

''Add new entries to the top of the list!''

27 September 2016 - [[User:ewaldo|Ethan Waldo]] 
USRP1 for Spaceblimp communications experimentation

1 July 2016 - [[User:Tom|Tom Iddings]] 
Borrowed a Dell D620 to put GNU/Hurd on it because it seemed like a good use for it. Maybe we can use it for an experimental OS development project?

17 May 2016 - [[User:ewaldo|Ethan Waldo]] 
Borrowed Altera DE2-115 to assist in further developing [[:Category:OpticalTableRobot|OpticalTableRobot]]

10 February 2016 - [[User:Mirage335|mirage335]] 
Borrowed T43 laptop used to drive pen plotter and remaining biosignal amplifier development components.

14 October 2015 - [[User:Mirage335|mirage335]] 
Borrowed miniVNA and extender to calibrate and optimally point a moderately-directional wideband antenna. EDIT: Returned a long time ago.

16 September 2015 - [[User:Mirage335|mirage335]] 
Temporarily storing a bunch of stuff from HacDC, to relieve some of the temporary storage pressure during the move. Most prominently,our biosignal amplifier, a bunch of high-power audio amps, a couple non-flyable quadcopters, a RC hovercraft toy, a telescope, some more legos, some toy night-vision goggles, the NI myDAQ/myDSP, and some IP cams. Will return upon request, hopefully sooner. Hopefully most of this stuff (ie. biosignal amplifier audio amps, IP cams, myDAQ/myDSP, etc) will be immediately integrated into the new classroom soon after the move. EDIT: NI myDAQ/myDSP returned along time ago. Returned the telescope, night-vision goggles, and IP cams.

11 June 2015 - [[User:Mirage335|mirage335]] 
Returned label printer, which is not useful without a special adapter cable among other things. Borrowed a bag of legos and empty microscope head for optical prototyping and photolithography experiments. Most Legos will probably be returning after replacement by 3D printed parts. Will return upon request.

27 March 2015 - [[User:Mirage335|mirage335]] 
Long-term borrowed amphibious RC car, power-line monitor, and label printer. Will return upon request.

17 March 2015 - [[User:Wa1ivd|wa1ivd]] 
Borrow Tektronix 2212 ser. H701215 from basement for Ultimate3S project, will return if needed.

10 March 2015 - [[User:Mirage335|mirage335]] 
Returned remaining screwdrivers and such. Borrowed an average oscilloscope, and low-end function generator long term, will return upon request or when tolerance for their existance at the space improves (eg. for a class event). Also borrowed one of the several wire-wrapping tools recent discovered.

3 March 2014 - [[User:Mirage335|mirage335]] 
USRP, related radio gear (some of which was built by me), wire, low-quality soldering iron, 2.4GHz R/C transmitter/receiver pair. Attempting to set up ham radio antenna at new QTH. Additionally, going to try repairing a model R/C plane with the R/C transmitter/receiver pair. Will return unused radio gear and supplies to HacDC when done, and donate for anything used. EDIT: Have returned some of the supplies as of 3/28/2014. Still borrowing USRP and soldering iron. RC plane may be able to use R/C transmitter/receiver pair if given new servomotors. Also borrowed a pair of decent pilers and wire cutters. EDIT: Borrowed SMT tweezers as of 4/14/2014, since my own set may not be adequate for an urgent project. Also borrowed M3 screwdriver bit. EDIT: Also borrowed soldering iron tip, while waiting on RMA from two other tips. Will probably bring back with some of the other materials within a week or two, time-ultra-critical project still underway. EDIT: Have returned almost everything. Still occasionally borrowing a few screwdrivers and other non-critical items, as some of my own have failed.

30 December 2013 - [[User:Mirage335|mirage335]] 
Prusa Mendel, and associated hardware. Minor repairs in progress, ETA return Thursday, January 2, 2014. EDIT: Returned Saturday, January 4, 2014. Performance and reliability vastly improved.

Prusa Mendel, PLA feedstock, M3 screws, some tape, some tools. Emergency maintenance in progress, ETA return Thursday, April 24, 2013. EDIT: Returned a while ago, seems the information was lost on wiki.

April 4, 2013 - [[User:Nocko|nocko]] 
Diligent Spartan-3E Starter Board (Labeled HacDC #12). I want to see if the SUMP logic analyser HDL can be modified and installed on this board.

December 18, 2012 - [[User:Mirage335|mirage335]] 
Project Salvage components. Most should become valuable electronic test equipment at HacDC and absolutely must not be trashed. EDIT: Returned a while ago to the test cart. Connectorization of some parts (eg. mixers) still progressing.

July 21, 2012 - [[User:Mirage335|mirage335]] 
Borrowing Ham radio gear this weekend, as described in the previous struck through entry. EDIT: Returned. Awesome data obtained.

June 29, 2012 - [[User:Mirage335|mirage335]] 
<s>Borrowing Ham radio gear tomorrow. Specifically, IC-718 radio, antenna tuner, RF power meter, balun (if available), PSU, some feedline, some wire, and a measuring tape (if >12'). Will also borrow some of my own objects at the space, specifically a UPS (for its 12V battery) and a magnetic loop antenna. Leaving my name and number on the ham radio cart in case anyone needs the radio or has questions. This is exclusively for the purpose of diagnosing HacDC's ham radio issues as documented on the mailing list.</s> Postponed due to severe weather and power disruption. Radio not borrowed yet.

May 30, 2012 - [[User:Mirage335|mirage335]] 
- Ancient (20 years+) semi-working AM/FM/WB/CB radio.
Found in basement. AM function never worked, in sorry shape, needs repair, so I'm going to try repairing it as far as possible. Will be back at the space in ~2 weeks. EDIT: Returned. After mostly mechanical repairs, AM, FM, CB functions work well.

April 2012 - [[User:Tslagle]]

'cause, you know, all the cool kids were doing it. 
I discovered that the unit I borrowed is flaky - after a few seconds of wearing it while powered up the display flickers and goes dead. I think that the cable leading from the power pack to the visor has a bad connection. When I get time I'll tear this one down and see if I can repair it.

* We should edit the bylaws so the board of directors' terms are staggered. Having a complete board turnover last year was not great.

* The White House is hosting a National Manufacturing Day (https://www.whitehouse.gov/blog/2016/08/08/call-action-celebrate-manufacturing-today-and-tomorrow) and part of the aim of the event is to "Linking manufacturers to the Maker movement by serving as the anchor tenant for a regional makerspace or supporting maker spaces in schools and after-school programs." I'm not sure what this means for HacDC except that it's a national makerspace/hackerspace event at the White House, down the road, with people who know what government programs can support hackerspaces. The event is Friday, October 7th. If there's a possibility of HacDC having an info table or booth, it sounds like a good idea to me...

* The memorandum of understanding (MOU) with High School Technology Services that allows them to use HacDC's classroom during business hours is expiring. They would like to renew it.

IT systems are functioning nominally. Replaced the classroom Wifi since the 5Ghz hardware was not stable. Also got the classroom room mic working for the web conferencing. Need to fix whatever broke the WebRTC compatibility. Also fixed a Wifi AP for the church and provided general email support. Haven't set up the Linux repo mirrors yet, plan on doing that soon.

http://wiki.hacdc.org/index.php/HacDC_CRISPR

We received the DIY CRISPR kit and inventoried it. We've made the small classroom fridge a "NO FOOD" project fridge because we now have bacteria cultures in there. The cultures and DNA and RNA require refrigeration. (The bacteria is E. Coli HME63, if anyone is curious.) The recipe ("protocol") takes multiple days due to incubation periods, so we're going through it once to verify we can actually do it with the equipment on-hand. Expect we'll have materials left over to repeat the experiment several more times.

=== Project Spaceblimp ===
We have had several fantastic meetings and are starting to break out in to individual teams based on project area outlined in the [[HacDC_Spaceblimp_6|Spaceblimp 6]] page. Please email me or one of the lists if you would like to be on the spaceblimp@hacdc.org email list. We are looking for members to contribute their PA funds for PA Spaceblimp and are taking individual donations that can include parts/components. The Funding team would like to ask the membership about adding a special Spaceblimp donation link directly on the HacDC website, possibly close below the HacDC donation link on the left rail. The Spaceblimp donation link would be up for no more than 6 months.

2016-07-26T21:54:12Z

Ewaldo: Merge groundstation and logistics project

{{:HacDC_Spaceblimp_6/Header}}

=About=
The communications project will deliver a balloon payload that allows receipt of [https://en.wikipedia.org/wiki/Telemetry telemetry] and other payload data as well allow command of the balloon systems as needed. Communications are commonly delivered over [https://en.wikipedia.org/wiki/Amateur_radio Amateur Radio] frequencies by licensed operators. Networks like [https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System APRS] are favored for some balloon-related communication.

These team members will also be responsible for ensuring one or more suitable ground stations are in place to reliably receive data from the communications systems. This team is encouraged to partner with the [http://www.w3hac.org HacDC Amateur Radio club] and [http://www.arrl.org/find-a-club other amateur radio organizations] and enthusiasts. This team will also facilitate logistical communications primarily for the launch and recovery teams.

=Team Members=
*Derk
*[[User:Ewaldo|Ethan Waldo]] (licensed for Amateur Radio)
*Martin (licensed for Amateur Radio)
*Nancy Wolfson

=Possible Balloon Communications=
* Primary VHF APRS tracker - sends regular APRS beacons with GPS and limited telemetry - use national 144.390 MHz network
* Secondary UHF APRS tracker - sends regular APRS beacons with GPS and limited telemetry - use a frequency to be determined at the launch site
* 13 cm Broadband Downlink - send realtime video or broadband data
* uhf/vhf cross-band repeater - allow hams to communicate long distance with handy-talkies
* 433 MHz ISM band low data rate telemetry

=Possible Chase Team Communications=
* Cell phone WiFi for APRS.fi information
* VHF and UHF APRS receiver, possibly tracking, text and digitpeating for off-grid operations
* Primary Voice - cell phone
* Secondary Voice - VHF and UHF mobile radios in conjunction with repeaters for off-grid operations operations

=Possible Ground Station Communications=
* 13 cm broadband receiver/recorder with 90 cm dish
* UHF/VHF receiver/recorder for SSTV

Project Summary

Project Code: Spaceblimp
Project Contact: Ethan Waldo
Project Status: Proposed

Project Description: Fund Spaceblimp!

Links To Other Project Pages: [[Spaceblimp]]
License or IP status: Project developments are not expected to be affected by upstream licensing

Additional Info: This is a general fund for any and all Spaceblimp related costs not limited to hardware, balloon filling equipment and supplies, and food and drinks for reasonably sized launch events with only remaining funds. This will not be used to reimburse anyone for equipment use, travel costs (i.e. gas/mileage), or time and expertise since that should be covered by volunteers. The plan is to launch several Spaceblimps with the current Spaceblimp project's Project Awesome funds overseen by the [[HacDC_Spaceblimp_6/Projects/Funding|Spaceblimp 6 Funding team]] making requests overseen by the HacDC Treasurer.

The project owner (Ethan Waldo) desires to run this project as a representative democracy, allowing all members a reasonable opportunity to push proposals and vote, but with oversight by the Board of Directors who will be responsible for any conflicts that cannot be resolved autonomously.

Examples of equipment or services that may be needed or desired at one time or another:
Balloon
Helium
Payload enclosure (i.e. lunchbox)
Discrete PCB components (i.e. resistors, capacitors, relays, ICs, etc.)
On balloon radio systems
Sensors
Microcontrollers
Batteries
Cameras
FPGA kits

Ewaldo: Project Awesome Spaceblimp

Project Summary

Project Code: Spaceblimp
Project Contact: Ethan Waldo
Project Status: Proposed

Project Description: Fund Spaceblimp!

Links To Other Project Pages: http://wiki.hacdc.org/index.php/Spaceblimp
License or IP status: Project developments are not expected to be affected by upstream licensing

Additional Info: This is a general fund for any and all Spaceblimp related costs not limited to hardware, balloon filling equipment and supplies, and food and drinks for reasonably sized launch events with only remaining funds. This will not be used to reimburse anyone for equipment use, travel costs (i.e. gas/mileage), or time and expertise since that should be covered by volunteers. The plan is to launch several Spaceblimps with the current Spaceblimp project's Project Awesome funds overseen by the http://wiki.hacdc.org/index.php/HacDC_Spaceblimp_6/Projects/Funding team making requests overseen by the HacDC Treasurer.

The project owner (Ethan Waldo) desires to run this project as a representative democracy, allowing all members a reasonable opportunity to push proposals and vote, but with oversight by the Board of Directors who will be responsible for any conflicts that cannot be resolved autonomously.

Examples of equipment or services that may be needed or desired at one time or another:
Balloon
Helium
Payload enclosure (i.e. lunchbox)
Discrete PCB components (i.e. resistors, capacitors, relays, ICs, etc.)
On balloon radio systems
Sensors
Microcontrollers
Batteries
Cameras
FPGA kits

A collection of stuff about HacDC's near space initiatives, including the ''Hackerspaces In Space'' Contest entry (2010).

=Current Status=

We are reviving the HacDC Spaceblimp project once again. Traditionally, Spaceblimp has been a multi-discipline club effort to build, launch, track, and recover a [https://en.wikipedia.org/wiki/High-altitude_balloon High-altitude Balloon]. So far HacDC has launched [[Template:Spaceblimp|5 Spaceblimps]], with [[HacDC_Spaceblimp_5|Spaceblimp 5]] reaching a maximum altitude of 118,533 ft.

= Come be involved in [[HacDC Spaceblimp 6|Spaceblimp 6]] =

Since Global Space Balloon Challenge 2016 (GSBC) just ended, there is no better time than now to start planning for participation in, but not limited to, the GSBC 2017 challenge. HacDC has had some preliminary discussions with the Naval Research Laboratory (NRL) regarding some of their STEM initiatives which align well with our Spaceblimp project. This presents a great opportunity for HacDC to collaborate with the NRL and local area schools to assist students in preparing for the next GSBC or other balloon events. Besides helping young minds grow, we could also expand in to other STEAM initiatives and work side-by-side with distinguished researchers and scientists from the NRL.

Supplies and equipment are not an issue. Hands on help is. We need embedded hardware, software, FPGA, and RF engineers, licensed amateur radio operators, project developers, crafts people, decorators, coordinators, outreach specialists and educators. However, no one with helping hands or a willingness to learn will be turned away.

=History of the HacDC Spaceblimp Project=
* On Aug 7, 2010, we launched our first balloon: [[HacDC Spaceblimp 1]]. Its epic journey began well enough, but the antenna came loose somewhere around 60,000 ft and we never heard from it again. Until three months later, when a farmer found it in her field, called up a friend (who happened to be an engineer) and it came back home. The pictures are fantastic, but the telemetry data was lost -- it overwrote itself many times over before the batteries finally gave up.

* Following (what we thought was) the loss of Spaceblimp-1, we scrambled and launched [[HacDC Spaceblimp 2]] on Aug 21. It went flawlessly -- fast, light, and with good radio contact the whole way through. It may be the third fastest-ascending amateur radio balloon. We were disqualified from the Hackerspaces in Space competition because we went over budget, but they said we would have come in fourth if not. Sigh. But again, it was an inspiring success.

* [[HacDC Spaceblimp 3]] was successfully launched and retrieved on 13 Nov 2010 with a much more involved payload than previous versions. More cameras, HD video, more radios, an accelerometer, geiger counter, pressure sensor. Weight and price weren't constraints this time.

* [[HacDC Spaceblimp 4]] set the HacDC altitude record, topping out at 103,764 ft! This flight got fantastic video -- make sure to check out the two youtube links.

* Insatiable and unstoppable, the HacDC team puts up [[HacDC Spaceblimp 5]] on July 9, 2011. We bought a yet-bigger balloon to try to get higher, and so: 118,533 ft!
