Default Home made Pulse to tone convertor

This may be of some interest, I just found it after considering buying a 746 phone in a charity shop.

Once again a spelling mistake, should be CONVERTER with an E, I despair at my rushed typing sometimes.

Yes I made a few of the forerunner of those. I was trying to get the first one going for about six months on and off and had practically given up, when by chance I saw this by Joe ThePillenwerfer

I managed to understand Joe's instructions and it got me into programming the ATtiny85, I have since used them for other projects too.

Here is my final version, it's a good deal neater than my prototype. The two boards form a sandwich in the case.

I was aware of the Matt Millman code and simplified hardware, but I haven't tried it.
