nixforever Posted October 14, 2005 Author Share Posted October 14, 2005 am reproiectat circuitul ca nu imi placea cum e acolo si am pus GND-ul direct pe cupru ca sa nu am probleme. Te rog sa te uiti peste schema si sa imi zici daca sunt destul de groase circuitele Link to comment Share on other sites More sharing options...
