Bench power supply from pc's power supply
« on: October 17, 2011, 00:46:05 AM »
Hello to all...
Well in this topic i will introduce you a bench power supply from pc's power supply that i made few days ago.I have a variable power supply made by me but sometimes you need to work with more than one voltage.So the pc's power supply can give us 5 voltages which are the  +3.3 ,  +5 ,  +12 ,  -5 ,  -12 .These are the most common voltages that electronics work.Also pc's power supplies have great amount of amperaze which make them versatile to lot of uses.In the photos below you will see that i have added a regulator (7809) to have this voltage also to my power supply.Another intresting thing is that i have added a connector (green one)to connect the antistatic bracelet when i prototyping with microcontrollers or chips which are sensitive to static electricity.Also a fuse case was necessary where has been placed to the positive cable of the power supply.All the info i needed can be found here ....  http://pcbheaven.com/wikipages/PC_Power_Connectors/

Finally i would like to THANK Kam for info and his power supply donation....

Hope you like it and built one for your own.

This green connector for the antistatic wrist wrap  is absolutely cool! You've done a very nice job mate.

Next addition: PIC current meter and variable voltage output with (PIC of course) voltage meter :D :D :D
