Hi ! I am still looking for parts for a project my son wants to do for his scout troop on an echo chamber. Due to the fact that we are very short on funds and bucket brigade chips seem to be a collectors piece...I figure we could ask for anyone with old record, erase and playback heads from old tape recorders or just old tape recorders (reel to reel will be the best) to donate them. I figure if the oildrum technology and the chip technology is too expensive and complex maybe an old fashioned tape echo might be simple enough. So PLEASE! if you can help out please let me know.
