Yes i am aware that there are plenty of other hacks of this type but mine will be in lots of detail for anyone who has never hacked one before. This hack is paticularly useful when experimenting with motors, arduino or other mico controller circuits, to power a battery charger and any other electronic project that requires external power. I used the first one I made for about a year and it is still going strong, this is just V2.
First of all I would just like to say that the steps in this instructable are based around an Eagle DR-A350ATX power supply, unless you are useing the same power supply then the information in the instructable should be used as a guide only. I also take no responsibility for any injuries, property damge caused by steps given in this instructable, however if you follow the steps correctly you shouldn't have any problems. Also one final not you are working with potentially high voltages (paticularly inside the PSU its self) don't make the same mistake as me and work inside the PSU case while it is switch on or you may get a nasty shock.
philips head screw driver
drill with drill bits
1 ATX switching power supply $20 for a used one or pull one out of an old comp
1 switch $2
12 banana plugs $ 14 (at jaycar)
1 project box/ tupaware container $ 5 (at jaycar)
heat shrink tube
various bit's of wire
superglue or epoxy
all of these materials can be bought online at jaycar.com.au
Plese forgive my spelling it is rather bad :(
Thanks and have fun
Step 1: Removing the power supply from a computer case
Firstly you will need to remove the side pannel of your computer which is usually held in place by several screws on the rear of the case. Once these screws have been removed slide the panel towards the rear of the case and then lift it up and out (Your case may be different). Next identify the PSU and disconnect all of the wires leading from it, now remove the four screws that hold the psu in place on the rear of the computer case. Now just pull the power supply out and your done.
