Thanks for the appreciation!

salut! imi poti trimite si mie schema?

ma tot chinui sa caut o schema simpla, si gasesc numai cu microcontrollere

si vad ca ai nuste tranzistori, niste rezistori si alte piese simple.

multumesc anticipat

@RetroVintageItems27 you could have them across the world if you wanted!

[gurbanliye]

very creative... It is a little scary when you approach a phone and take it :D

[RetroVintageItems27]

Can you use that in an intercom situation or I guess it is but could you have the telephones in different rooms? Nice job you do that your self?

I think that is neat.

I will cheat and use an pair of line cards and wire them back to back.

Viking electronics sells modules that do the same thing.

Did you make that yourself? If you did I would love the schematics! Nice JOB!
