Wood with foil......

Dear friend

695 posts in this thread (including this one).

A couple of finished Franco's devices and you are still asking for "complet projet"?

Maybe you need to read this thread from start.

hi all friends

anyone have o complet projet.

thank you

The project is a little critical. I sujest you to read carefully all the posts so to understand it and to give carefull at some points. Best version (most easy) is the 8Mhz xtal
Good luck

Hi walkman,

In this case power supply should not be 12V as marked on PCB, but something near to 15V.

[FrancoItaly]

the power supply is 18 V (2 X 9V battery) the IC is 7812 that, yes, requires more than 15V. Usually for low battery voltage I fixed 16V then an operating range from 18V (full charge) to 16V.
