[HBQRP] Scattered links previously delivered

[Sean Pepin]

Sorry, it seems that the list only allows completely plain text posts 
devoid of embedded links and pictures, which is a pain to say the least. 
I guess we'll have to party like it's 1997.


Hey folks,

Here's the scattered list of links I promised at the last meeting.

The acrylic case I was showing off was produced as a project by 
Dangerous Prototypes. The project name is 'Sick of Beige'. All of the 
Dangerous Prototypes stuff is available at Seeed Studio, which is an all 
purpose hobby electronics company in Shenzhen. The cases are $3 for any 
size.

The prototype board manufacturing house I mentioned was OSH Park. These 
folks spun this business off from a robotics club group buy system they 
set up to get cheap panels made. This is a cheap, high quality service 
at $5/sqin shipped for three copies.

I made a spreadsheet to calculate approximate costs for large and small 
runs from OSH Park including the cases from DP. It's embeded in a post 
in DP's forum, so you may have to register to download (not sure).

The oscilloscope introduction document from Tektronix called 'The XYZs 
of Oscilloscopes' is available all over the internet through gooogle, 
but the most recent version can be downloaded straight from Tek's 
instructional webpage. Registration is required, but it's free.

Did you know that the Raspberry Pi can be programmed to spit out FM on a 
gpio pin, up to 250MHz and with full stereo and preemphasis?

Those asking where I get my 'cubic foot of random parts' from, it's a 
place called Electronic Goldmine. The box is cheap but the shipping can 
get expensive. It does weigh quite a bit. I send them an email once 
suggesting they set up a subscription service but they never responded.

Those with cheap Chinese transistor testers may be interested to know 
that the original project started here (translated). The project is now 
maintained by Karl-Heinz Kübbeler, and the most recent info can be 
downloaded on his project page (translated). The SVN repository for the 
latest firmware and documentation is here, just download the tarball and 
dig down for the english manual. It's 84 pages and very detailed, and 
also covers the knockoffs in a section called 'Chinese Clones'. The 
latest version is 1.10k.

Those who are more familiar with oscilloscopes may be interested in this 
video. Dave Jones shows the main differences between the older and newer 
generation Rigol scopes. Absolutely required if you're planning to make 
a purchase in the next year.

Please let me know if I forgot anything.
