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

I have been privileged to see this thing in person. It is truly a work of art!
Thanks friend, it is getting time to work on some other projects!
This is beutifull.
I know what you used for the Wrist Control Unit, and I must say, I would never have thought of that. Excellent work, Sir.
Very nice job.
Thank you.
Love that brass meter in the middle. Is that a surplus find?
the large brass meter in from an old radio station, this one was rusty so I reworked it to work as a voltage meter.
Beutiful build! I love the sound it makes when you turn it on. Where did you find all those great old panel-mount meters and switches? I assume the switches were old judging by the great clicking noise the made. I'd really like to know! <br> <br>Great job! <br> <br>CC
the switches not that old, most are spst from DYI stores and the loud click you hear at the start is a relay
Greetings all. the meters are from here and there in the net but most from here at my monastery. the brass meter was painted with enamel. I will add a list to this project where i got most of the stuff, however i will be building a new power supply (version 2.x) and will explain the possess better
I am intersted in knowing where to get the meters too.
Awesome project!<br>I love the idea.<br>It's too bad that tesla punk has to do with free energy.<br><br>(Rant excluded)<br>
Truly inspired build... Well done! (And I just learned a new word, &quot;<a href="http://en.wikipedia.org/wiki/Teslapunk">Teslapunk</a>.&quot;;-)
Very neat bench power supply! Very much Teslapunk! (An offshoot of Steampunk in which early electrical devices are more dominate over steam and clockwork...)<br>
thanks! I think my next version will be more steampunk, oh and thanks for the info on teslapunk I will have to look it up.
Teslapunk, I like how that sounds. I never much went in for Steampunk although I have read <a href="http://en.wikipedia.org/wiki/The_Difference_Engine">the book</a>.
You should put one of my supplies into yours instead of just an ATX one.<br> <br> <br> <a href="http://www.instructables.com/id/300-Watt-Linear-Power-Supply/">300+ Watt Linear Power Supply</a><br> <br> <br> or<br> <br> <a href="http://www.instructables.com/id/Dual-POS-NEG-Power-Supply/">Dual POS-NEG Power Supply</a><br> <br> Granted the second one could use a case but in practice I just put it onto my breadboard. I suppose my first one isn't very stylish either, but the box I made keeps things from falling into it.
