I do not have time right now to put an instructable together, however I thought I would post this to get others to come up with better looking desktop power supplies. This one has a 1.24 - 10v DC out with amp and voltage meters, a 12v out, 5 v out with amp and voltage meter, and a 110v AC voltage and amp meter! The center tube is a working tube while the left and right tubes are burnout. All 3 tubes have been converted to work on 2 volts (a small light bulb inside the smaller tubes and a light out side in the back of the larger). What I will do over the next few mouths is to post short instructables leading up to the final power supply I will build in January so keep an eye out.
The system power (on and off) is controlled by one large relay, this is done so that the 110v AC socket on the right side of the power supply is not routed through the box or the 2 amp switch just a small current now flow from the switch to the relay. Believe me when I say there are a lot of wires in side this box so it is very important to keep them sorted. I have supplied a schematic but it is for reference only right now.
update: the schematic shows a resistor in the wrong place and the switch to the relay is is the wrong place. I have updated the changes
