Needed: Sort-of-working touch tone phone
Posted: Fri Sep 11, 2009 5:22 pm
I need to create a tone generator for our hillclimb timing system and would like to cannibalize the guts from a working touch tone phone. I actually recycled 3 of them just a month or so ago before I know I would be asked to come up with this generator.
So, if anyone has one that works - more or less - and wouldnt mind bringing it along to Ascutney to donate to the cause, the NEHA timing system effort and I would appreciate it a lot.
More or less working means as far as you know when you press a button it generates a tone. The condition of the case, any batteries, the earpiece and mouthpiece and buttons themselves dont matter as they will not be reused for this.
Thanks!
