Aiyoh.... you know nuts about engineering, u want to make a DC power supply. U kena short circuited, I will be held responsible leh...
hmmmz~ here's the prob: im not into engineering!!!! i know nuts abt it! teach teact a bit lehz
Tell you oso dunno, bring u there far far!
I always wanted to say that!!
first of all, u'll need a electrical diagram with those electrical thingies on it, also called a schematic diagram. I have that diagram. Buy those components (solenoid, electrolytic capacitors, resistors etc) needed and also a chassis. Some drilling of the chassis is needed. Follow the schematic, solder here and there...VIOLA! You have a DC power supply.
If you really wanna make one, be really really careful, ok?
