i would like to start off by saying this is my very first instructable.
This projects was started by me looking for something to do with an old computer i have that is out dated and virtual useless. I saw a few PSU (power supply unit) to bench top power supplies on youtube and decided that this was a good idea.
A source of power i may need for future projects the deeper i get into electronic prototyping/engineering/fiddling
a gift for my Dad to replace his older louder bench top supply
*I claim no responcibility for personal property damage or damage of ones person by following this instructable*
Tools Needed: Screw Driver(Philips), Dremel with abrasion grinding disk, Metal File,Wire Strippers, Soldering iron+solder and stand, EYE PROTECTION
This power supply will have 3.3v,5v,12v,-12v,& Ground, with a well placed illuminated power switch.
Bill Of Materials:Working PSU, 5 banana jack binding posts($3.19 per pair of 2), (optional test/jumper leads $7.49 for a 6 pack, project enclosure 7x5x3" $8.99)
PSU from the ribbon cable era. i will not be going into spec. details because i feel that there is little to no need. Small differences may exist between different manufactures but for the most part all PSU's are the same
open your PSU after waiting 10-15 minutes after being plugged into wall. Clean out all dust and computer nastiness
I apologize for skipping a step but. Grind out hole with Dremel for switch. Place switch into hole
Grind out spaces for banana plug posts. You do not need to use ventilation grate for mounting for components. This is the only place where i had room internal to mount and wire everything.
Grind out as many holes as needed. i had planned for a sixth post but i didn't have enough space (six holes, only five posts)
after all this cutting and grinding i strongly recommend a quick pickup.
Cut off all pin connectors. in this project i only used wires from the 24 pin connector but if u wanted or needed more binding posts all wires are usable for their ratings.
