While in Norvac The other day I was browsing in the IC section and came across this little gem:
I think it was the Jim-Pak packaging that did it (Jim-Pak was a single serving component vendor that has sadly gone the way of the sort of places that sold it)

I've always made PCB's by the Photo fab method, with varying but never entirely satisfactory results. I was also somewhat put off by the need to buy pre-sensitized boards, at ridiculous prices. at a meeting earlier this year I was talking to Don ( feurig ) about it and he suggested I try the Toner Transfer Method (note reverent capitals).
The following was heard over a soldering iron at our casual Dorkbot gathering last night:
"Christ, that night in the hospital...my underwear was covered in ferric chloride stains."
Heh. :) I couldn't stop laughing....only at Dorkbot!
In the last week or two I've been doing some of the smallest soldering I've ever attempted.
It all started with the KOLPXNTY board I've been designing and prototyping. I won't dive into detail here (maybe later!?), but the basic goal is to trigger a fairly large number of circuit bent devices from a networked computer.
I'll put up a documentation page if/when it's more relevant.
A friend directed me toward Dorkbot for help with my project. To put it most bluntly, I want to control a cassette tape with a pair of stepper motors via MIDI. From my research, I think the easiest way to build a prototype would be with a make controller programmed with MAX/MSP. My personal background is in studio engineering and production. I am knowledgeable in most forms of audio manipulation. Unfortunately I have yet to learn the ins and outs of MAX.
Built for sound. Beautiful sounding bass sound. tuned PVC pipes. hit with flip flops.
That was me busking at Last thursday under the awning of acme glass.
