These are both ETG shots. The first was at the base of the ETG looking up and recording (its a still). The second one was my first attempt at a long exposure. Time was 3.2 seconds with a Kodak 10MP digital camera.
first two here:

It wants leaded fuel, even the substitutes aren't too keen on the engine.

If a Nimbus stops spewing oil, its broken :D

Value sparks? Its open valves driven from the upper crankshaft, rather innovative for its time.

I ripped out a pair of 2n3055's that failed likely due to a voltage spike (from disconnecting a large inductive load), here is a pic from inside:

have you tried using it as an 'LED' now?
there was some pics of people doing that some years ago, if you can find the thread.

1231191543 599 FT6000 3phladder


6 microwave oven transformers fed from 16amp 3 phase outlet. Every phase has 2 MOTs antiparallel. Primary and secondary windings are connected in star configuration. All three ladders are in HV potential but different phase.

Link2 Short youtube clip. Transformes get barely warm but my 3ph ballast got toasted :D I will add second row of 6 MOTs there as soon as i get my 3*100A outlet installed. Whole thing will be rectified and used as TC powersupply. Will post schematics, more pics and stuff soon to projects.

This is my version of Uzzors' SMPs built inside a rackmount PSU case. I think it is probably the best looking (and hence coolest) thing I've ever built, so I posted it here. I still have to work out a problem with the voltage feedback (suspect screwed up TL494 due to accidental 22V on pin 1 while testing).

Neat. I've updated the page so it actually has some information on it it now, you might it useful. I'm surprised you were able to put it together with just a schematic, some pictures and a lame description, good job!

More Power!!! I'm a Server Engineer, and my server lab was lacking in available power. Our Electrical Contractors are here today installing my new panel and isolation transformer. Took a few weeks complaining to get it done, but this is what I got...

30kVA 600V Primary (D) - 208V(Y) / 120V(S) Secondary.
