DIY Power Supply Design

frnds this is also one of the power supply i made from old PC PSU but still i dont have much pics of steps i take to make it just it is a final design i made although inspired by things i have in my store

in the right hands side terminal blocks are connected to +3.3 / 5 / -12 / +12 volts lines and also using the lm317t voltage regulater i made a little circuit to have variable supply at one of the binding posts i used here

i used to SPDt switches to switch it on and off and there is built in fan in it so there is not any need of any type of cooling system

this is design so my idea is to give people thought that first use those things that u have in your pockets for any type of DIY projects then go to shop anything for any kinda projects
