Cheap electronics – Goodwill online auctions…
I didn’t know Goodwill had eBay-like auctions, but they do. Make reader zw suggested that the “Cameras & Electronic Equip” section has a lot of good deals and interesting equipment. And it’s true, there are a ton of weird and cheap electronics, most of them under $50. I also saw a new 4G iPod for $150. I’m not sure how good the actual purchase and delivery is, it seems the member organizations of Goodwill Industries International are the only sellers. It might be worth checking out. Link.
Peter is looking for some Makers out there, he writes “Basically, the folks at National Instruments have added DSP (digital signal processing, useful for lots of audio applications — both industrial and musical), to LabVIEW, their high-end development platform for creating test / measurement / control applications. Here’s the cool part: they designed a free synth (as in musical synth) to run on the platform. Somewhere out there, there’s a scientist or engineer who’s going to love fiddling with this thing. It’s electronic music for Dr. Bunsen Honeydew. Know anyone in those communities (blogosphere or printosphere) who might be interested in this?” 
Here’s something to make when it’s cold outside. Snow! This site has a couple of snow machine designs that can be built from stuff you might already have (an air compressor, a high pressure sprayer, various plumbing fittings). There also has a page describing the physics involved in snow making. Thanks J. Wolf! 
Run a Mac, on a stick. “Running Linux, Windows or applications like Firefox, Thunderbird and AbiWord from a USB flash memory device is old hat. How about a Mac 128K or Plus on a USB key? Using a ‘portable’ Mac system you can: play with old system software and applications without dusting off your old Mac, impress your friends, or show others what the older Mac system looked like, use Mac on Windows and Linux.” Thanks Jim!

More repairing goodness, Radiorental writes in describing tips for scoring super cheap iPods – “There’s usually half a dozen 10GB or 15GB broken ipods on ebay at any point in time. Usually either the battery or HD is stuffed. Most go for under $35, new battery is ~$10, HDs are around $100 for a 40G. $140 total for a 40G 3rd gen Ipod thank you very muchness.”
