In addition to the pressure sensors mentioned in a previous post, I need touch sensitive switches. They should be: - about the size of a nickle - able to sense a finger touching the switch - not flaky, i.e. a clean on/off signal when you touch/untouch the switch I am considering making the contact part of the switch myself (perhaps cutting disks out of copper-clad PC board material and etching a pattern on them). In that case, I need a (simple?) circuit for sensing a touch, debouncing, and amplifying to TTL level. Does anyone have a circuit, or know of a good reference book for this info? Or, does anyone know of an electronics supplier for switches like this? Thanks in advance, Eric Singer es1e@andrew.cmu.edu
