03/22/2006: "Part 1: Gathering parts and cleaning up"
I started with a power supply that I harvested from an old e-Machine. I liked this unit because of its size. My work space is limited so the smaller the better.
In addition to the PSU I will use the following parts in this mod. 5 way binding post (6) LED assembly from Radio Shack (these have the resistor and LED holder as one unit and only cost a couple of bucks) 10 watt 10 ohm power resistor Fuse holder SPDT mini switch And spare molex connector
When I opened up the power supply I could not believe how dirty this thing was!
A soft brush and a can of air were all that were required to get it cleaned up.
After cleaning the inside the next step is bundle like wires together.
After bundling the wires I removed the circuit board from the case so I could trim the excess wires and guess what I found, yep, more dirt.
Once I finished the cleaning I then counted the connections I needed and removed the unneeded wires.
Now it was time to layout and drill the holes in the front of the ps for the LED and the binding post. I would mount the fuse holder where the wires originally passed through the side.
The next step was to scan the front of the case. This would give the layout of my holes and help me place my labels. Once my design was complete I printed it out on a full sheet label and stuck it to the front. Using an Xato knife I cut the holes for the various components.
I cut the backing so it would keep the top from sticking. I had to keep this loose so I could put the screws back in before I sealed it down. Also note the on/off switch mounted on the back of the unit indicated by the red arrow.
In the next post we will install the binding post, LED and fuse, replace the circuit board and wire it all up.
