    RF CO2 build

    The two green lights mean you are getting good RF power out of your board. The problem is probably the transistor floating off the tube ground. Mount it to the tube and it should fire. The rf pre-amp board getting warm is good, that means your main RF transistor is working. I found the...

    Holy $#!% Ultra-Capacitor

    One neat use of these caps is with a powerful DC-AC inverter to supplement a 12V battery bank to build a solar water well pump driver. These caps have enough kick to where you can use normal heavy duty deep cycle batteries for this project. You can also make a emergency car starter rig with...

    BIG capacitor bank

    I find microwave oven diodes to be the best diodes to use for pulse power HV projects. I would go for series parallel config for 1400V. Due to the high transient amperage and ringing, I'd use a spark gap switch with a little argon/co2 mig gas as the dielectric since the device is moderate high...

    Tunable HeNe on ebay??

    It is very obviously dead. Dec 1987... These lasers only last about 10 years MAX idle, and it probably came from a lab bankruptcy sale of the "we no longer use it" room. Like argon lasers they need to be run at least once a month for at least a few hours to keep the tube healthy.

    Nanocups Produce Frequency Doubling

    Great... We now have the first component to a time machine; a negative refractive index nonlinear optical medium.

    Excimer laser head

    You could use xenon/chlorine to fill it also. Fill to about 625 torr of helium, add chlorine to go to atmospheric pressure , let sit a week and run the laser for an hour or so. Then pump to hard vacuum. Then you can fill with xenon chlorine eximer gas. The manual states pressures/mixtures in...

    460nm 1W Blue Module on eBay (my auction)

    These are diodes used in the newer higher lumen C****o projectors. They are also used in handhold picro-projectors as well. Can't wait until we get direct green diodes.

    Excimer laser head

    If it still has the cap array you can use it as a nitrogen laser, also you can fill it with eximer gas mix, but it's tricky to get ahold of.

    Maxwell Ultracaps 3000 farad 2.7V

    FWIW, Use a brake light bulb or other low voltage high wattage incandescent light bulb as a current limiter

    Maxwell Ultracaps 3000 farad 2.7V

    How about get a bunch of these caps, some high power bar emitters, a big YAG rod with resonator assembly, ssy-1 Q-switch, and make the pulsed DPSS laser from HELL.

    I am looking for a high powered co2 laser

    The synrad laser is a work of art and would be hard to make in low cost. It requires a special tube waveguide assembly made of beryllia, a couple passivated titanium antenna electrodes, a titanium passivated stainless steel resonator structure, In addition it has expensive rf amplifiers inside...

    B&W Tek BWB-10-OEM - 473nm 10mW

    They come from American biosciences gene sequencers and scanning confocal microscopes. They have been replaced by direct diode lasers. They sell on ebay for a small fraction of their new cost.

    Melatonin.. Sleep support? Or Sleep preventer?

    Melatonin causes me hallucinate more than sleep. I find the only thing that works well is some chamomile tea and meditation.

    Harvesting / Teardown of the Pico1 Projector - 450nm, 640nm, + non-DPSS Green

    IMHO, I doubt it really is a single pass ppln device, more like a extended cavity device. One way to find out.....
