Bench power supply from pc's power supply

Hello to all...

Well in this project i will introduce you a bench power supply from pc's power supply that i made few months 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 cable case was necessary where has been placed to the positive cable of the power supply.All the info i needed can be found here ....

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

Hope you like it and built one for your own.ANY COMMENTS OR IMPROVEMENTS ARE WELCOMED.

I was thinking about doing this, but had no idea on how to procede. Thanks for your information and helping me come a step closer to getting my project underway.

Thank you George for your good comments.Yes i agree that a step-up supply would be a nice addition to my project....Maybe when i find some time to make a "renovation" to my supply!!!! :-)

You could also add a 0-30 step-up supply (1-2A) with display. This is something that i always want to add to my bench supply, but i always forget to start. I remember this every time i miss some strange voltage...

This is the first DIY PSU that i see with connector for anti-static wrist wrap. Taking into account that you have this bad habit to grasp those poor PICs bare-handed, it is a feature that will certainly save you some money. My next PSU will have this as well. Great idea.
