This is the Alphabet Zoo. A friends dad was going to throw it away cause apparently it had been sitting in dudes backyard for about 3 years. I took the old battery's out and cleaned the terminals which were very corroded. Put in some new batts and fired it up. It sounded great! I took it apart and inspected it to the best of my ability, sure enough i found its pitch resistor!
This one has a 100k pot attached to either side of the pitch resistor I have two switches, one to turn on the pot and another to extend the range of the pitch.
heres a video of it in action! :D
"Put in some new batts and fired it up..." I hope you checked your back blast area before you fired it up ;-) Joseph would love to learn to do this too. I bought a solder sucker, so he could sold some pieces off an old dish receiver. I think we are going to try some of this too. BTW a buddy at work told me about http://circuit-tutor.sourceforge.net/ to download circuittutor.zip
ReplyDeletehttp://101science.com/radio.htm is one of the sites I've learned much from, another is. There is also a book by a man named Reed Ghazala, I highly reccomend it. Its short, sweet and full of juicy ideas! Hes the guy that discovered circuit bending! I bet there's a .PDF of if floating around out there somewhere. Its worth buying though!!
