Free Media Stuff (audio)
In the Field: I host this radio program on WXRW LP-FM in Milwaukee on Saturday nights, homemade field recordings. There's an archive of past episodes here, as well.
Negativland's Over The Edge radio show archive: 941 3 (or 5) hour episodes.
UbuWeb: All avant-garde. All the time. Lots of rare audio and video recordings, and some printed materials.
BBC Sound Effects: 16,000 sound effects and short field recordings, downloadable in .wav format. A real goldmine!
electronics suppliers, surplus and otherwise
The Electronic Goldmine
surplus electrical/electronic/mechanical/other components. some of this
is pretty arcane. some of its a little pricey, but it'd be tough to
find some of this stuff elsewhere.
Alltronics all kinds of good stuff. decent prices, too.
All Electronics surplus components, lots of it. I've started looking here before anywhere else.
Parts Express Kind of reminds me of looking at a Radio Shack catalog from the early 80's--specializing in audio gear/parts. Between Parts Express and All Electronics, I've been able to pick up all the stuff I used to get at Radio Shack (inline jacks, battery clips, solder, solder wick, IC sockets, etc) for considerably cheaper.
Marlon P. Jones & Associates kits, some electronic components, but mostly larger building blocks, like power supplies and test equipment.
BG Micro kits and components. seems to carry a lot of the same stuff as mpja. good prices.
American Science and Surplus
surplus electronic components, lab gear, telescopes, kits of all types.
I'm lucky to actually have an AS&S store in town here, but much
like the online version, its usually not good to go here looking for a
specific item. But for browsing purposes, its fantastic. A 10-pak of UV-reactive plastic spiders for $2? Right on!
Small Bear Electronics
lots of really hard to find electronics, mostly geared toward guitar
effects components. I don't know where they find this stuff, cuz a lot
of it isn't being made anymore.
Mouser one of the big dogs of electronics supply. good stuff, great prices, good customer support. There's almost TOO MUCH stuff here, which tends to complicate ordering.
Digikey if Mouser doesn't have it, look here. *slightly* pricier than Mouser, but just as good re: selection and customer support.
EE Tools
Filter Design and Analysis notes and calculators for designing a myriad of different filter topologies. Fantastic stuff.
Gyrator Filter Calculator good tool for designing gyrators (simulated inductors using caps,resistors, and an active buffering device) for use in Band Pass Filters.
Synth DIY stuff
Cat Girl Synth Ken Stone designs
really great modules, from "building block" type stuff like power
supplies, VCAs, and LFOs all the way up to Super Psycho LFOs and
Bi-N-Tic Filters. He does a good job of explaining how they work. PCBs now sold through ELBY Designs.
Music From Outer Space
Ray Wilson designed and sold (PCB for) the awesome "Sound Lab", an
all-in-one, easy to build complete synthesizer. Also available:
1V/Octave keyboard driver, various filters, and the nifty "Noise
Cornucopia"!
Synth DIY with PIC microprocessors
Tom Wiltshire's well documented ADSR and LFO projects, both built
around the cheap but powerful PIC16F684 chip. I'm sorta surprised there
isn't more of this sort of thing going on. Maybe I should get on that.
The Electronic Peasant A site dedicated to building cool synth gear out of recycled junk. I've been a fan since I stumbled upon his ribbon controller project, simple enough that *i* could build it. and now doug blows my mind with his new banjo controller project! Holy Smokes!
weirdo web experiments
Luddite Centipede: even tho i never finished it, it never goes away. a crude but effective simulation of the arcade classic, i wrote it in javascript using text as graphics so anyone could play it, no matter what kind of machine they had. of course, everyone said it was "ugly and too hard to play", and it set fire to the first Mac it was tested on.
Collected Field Recordings (mine and others)
Colbeck Labs Field Recordings
Smithsonian Folkways Recordings The classics.
