If friends with look for Mini power supply 6V sizes. That give negative voltage. I begs for to advise this circuit. It has prominent small-sized point and light weight. Because do not use Transformer. But still can use current get 0.07Amp not exceed and when see the circuit. Think use Zener diode control voltage be [...]

This be Basic Dual DC Power Supply 6V (+6Vdc CT -6Vdc) . Which easily give a little electronics component economize good. But inappropriate for the circuit that use current the very much. Because this circuit gives current 50mA only just. I hope that this circuit may help to solve a problem friends in the emergency [...]

The main parts of this circuit is IC 7806,It is normal IC linear dc voltage regulator 6V at 1A current. It is easy project electronic because used the minority part and low cost too. I have of a 9Vac 1A transformer,The output of the transformer is rectified by diode 1N4001 or equivalent to more high [...]
