Wa1ivd: Bill borrows a scope

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

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.

April 21, 2013 - [[User:Mirage335|mirage335]] 
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.

'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.

* The FCC (Federal Communications Commission) definition of the Amateur Radio Service: ''' ''"The amateur and amateur-satellite services are for qualified persons of any age who are interested in radio technique solely with a personal aim and without pecuniary interest. These services present an opportunity for self-training, intercommunication, and technical investigations." '' '''

* The ARRL Technician License manual and study guide: http://www.arrl.org/ham-radio-license-manual . ''' ''Please look over this resource carefully before class. ''' ''

* A free license manual for the Technician class: http://www.kb6nu.com/wp-content/uploads/2010/06/2010_Tech_Study_Guide.pdf ''' ''Please look over this resource carefully before class. ''' ''

* FCC Part 97: Regulations pertaining to the Amateur Radio Service: http://www.access.gpo.gov/nara/cfr/waisidx_10/47cfr97_10.html

* The entire Technician class license pool, of which 35 questions will be randomly selected for your exam: http://www.ncvec.org/page.php?id=349

Not only will it give you good recommendations for being a good citizen on the air, it will also give you an excellent overview of the various facets of modern Ham radio. There is an excellent manual in PDF format you may wish to have available when you start using your new license.

* Founded in 1914, The American Radio Relay League (AARL) is the national association for Amateur Radio in the USA. Today, with more than 156,000 members, ARRL is the largest organization of radio amateurs in the United States. Check out their web site: http://www.arrl.org.

=== About the class ===

Add another tool to your Maker toolkit: an Amateur Radio License. Amateur Radio Operators (Hams) have a long history of "Homebrewing": building their own equipment and experimenting in the hopes of making it work better, and the community has grown a tremendous breadth. There is tremendous overlap between the Ham and the Maker communities.

HacDC has it's own club license: W3HAC, which we originally obtained to use ham radio for position tracking during our balloon flights using APRS (Automatic Packet Reporting System) on VHF and UHF frequencies; designing and building our own lightweight transmitter for the balloon payload. We have many Hams here, some with quite advanced licenses, and a bi-monthly meeting to discuss technical aspects of radio-based communication and build stuff.
