high voltage discharge into a beaker of water. We are testing out a pole transformers output, watch closely at the end when I ask my firend "whats wrong?" hehe
This roughly 30Kvdc output power supply was constructed from common materials such as PVC pipe, spark plugs, flyback transformer from discarded TV set and "doorknob" capacitors. Even recycled plastic bottles where used as insulators. The filament output is used the primary at 7-8VDC @ 2A 2Khz pulse. A demo with a solar panel is done to show of effictive this is.
A coherent 808nm laser bar burning though wood with an unfocused beam! If this beam was focused into a point with correct optics it would be much stronger.
The cooling system is a CPU cooler modified to do keep the GaAS diode happy as it consumes over 120 watts of power.
This is a test of my JetCat turbine engine. This is running off 1K kerosene as a substitute for Jet A-1. There will more of this motor later, but I had to get some video of it up.
100mW DPSS laser built into a empty Altoids tin. This was made from almost all scrap materials with the exception of the Nd:YVO4/KTP and 808nm pump diode assembly. The heatsink is from a stripped 21" monitor, the battery compartments and switch where pulled from scrap. The lens for focus the laser diode was pulled from a DVD burner.
It's been a while sinve I used the pole transformer on anything....so I hope you enjoy this video. First is a jacobs ladder then some snow melting on a piece of wood and a patato!
I am putting the Plastic Capacitors 50kvd power supply though its paces. The arcing cannot be picked up well by the CCD. We are using welder goggles to protect against UV from arc.
A friend gave me a non-functional LG1950 monitor that would turn off after a few seconds. Cycling the power on and off brought it back briefly. So he replaced his old screen and no longer wanted this one. I decided to have a go at repairing it, it was so easy I decided to share it with you.
