Circuit Project Electronic

When you want Dual power supply Variable Regulator be simple. I begs for to advise this circuit, because use the integrated circuit LM7805 and LM7905. Make have Voltage +5V to +25V and -5V to -25V unless. Still pay current get about 1A enough with [...]

Friends ever meet a problem experience Electronics Circuit at want the level Voltage various? Today I begs for to suggest Muti lab power supply 15V,30V,45V,60V Circuit may meet the requirement of friends get. By it is the circuit is simple use the transistor = 4 pcs (C1061,A761,2N3053,2N4037) only and Zener Diode ZD30V [...]

A friend of me you one take an interest a side Sound Audio the very. He takes an interest to want to build Pre tone Control which use the integrated circuit OP-AMP. By these circuit often use power supply Model Dual DC Regulator which have [...]
