yes i have print the pcb by screen printing method,with the help of negative BY a local manufacturer as there is no green coat on pcb it is compulsory to give a tin coat on tracks
the pcb can b made by home methode but it requires accuracy and spends more time
hey!! i have made this pcb myself but couldnt even able to light up the led, i have not yet connected to serial port. I am really confused about the input voltage of this circuit. i have tried giving it 16v AC but no sign of led going on.
