USB Experiment Interface board
This is a deal that you seriously can’t beat. About $30 for an 5 Digital Input, 8 Digital Output, 2 Analogue Ins and Outs. USB with a Dynamic Link Library to write software for. Seems to be windows only however. Avaliable via English Maplin Electronic site. Link to the product here. Free shipping in UK to boot!
Thanks to Hernando Barragan we now have what looks to be a very simple to use I/O board with a USB interface. The Project is called Wiring. (website) The board features 40 Digital I/O pins. 8 Analog inputs for measuring resistance and such as well as 6 Analog outputs!!
The code looks to be strait C++ with calls to the Serial port. Priced at $60 this is gonna be a hot seller. Shipping may be pricey still better then any thing else on the DIY market right now.

The Birth Of Electronic Music Part I by Nick Rossi and published by a Keyboard Publication has been digitized from the original slide and vinyl circa 1971. The QuickTime files are avaliable for Educational purposes only and should serve as a basic rough guide to the historical aspect of early electronic music. As far as I can tell Keyboard Publication/New Haven is not anywhere to be found online. The closest reference to Nick Rossi is here. I know that is not the right Nick because they were born the same year as the publication. This slide show is the only one in existence as far as I can tell. It was located in a middle school library before it got thrown out and retrieved back by my Professor. Use it as you will, just don’t sell it or take Nick Rossi’s credit.

After doing my usual random googling I found this awesome Electronic DIY Kit site
Some of the kits include things like…
Op-Amp function generator for $7.39
K81 – Kit 81 16C/F84 Development Programmer for under $27.
Now thats a good deal. May have to order one soon.
Also there are several kits with complete schems in PDF format.
Like this Audio to Light board
There is alot of potential that I see in these kits plus alot of them are super cheap ( $10 and under )
One of the first “No Nos” of circuit bending is modifing anything runs of AC and for a good reason I may add. AC current is extremely DANGEROUS and VOLTAGES present CAN be DEADLY. However that would single out half of the cool stuff out there.
Few weeks ago I picked up a pair of CDJ-1100 and after failing miserably trying to DJ I had better ideas for the units.
Circuit Bend them!
The cases are large and will accomodate alot of switches, contacts, and etc. When avaiable they don’t sell for very much on ebay. Typically between $30 and $80. They do have pitch control and a jog/scratch wheel. Everyone wants to have that on their modded CD players, yet noone ever does. This would be perfect. On top of that they look cool!
After getting bored with all the blogs I started googling for synth stuff and ended up on the PAiA website. Behold they had full schematics for their theremin as well as the building manual. Looks simple enough with only op-amps used it should be fairly cheap to build. The board may be the tricky part, but I imagine point to point will work as well.
A couple of videos are avaliable now. They do include the stereo sound recorded directly from the machine.
