Weeeeee!
That is all.
That is all.
Guess I will forget that idea and look to find a good deal on two small brick PSs--what do they use to power them when they are inside of a barcode scanners that these old tubes usually come from?Hell, it could power at least 4 of them in series. That's 25,000V or so. Not a good long-term idea though. I don't think the wave form is desirable.
My previous impression was that a flyback transformer could only source a few hundred uA, not the 5-8 mA needed to run a HeNe. Though the voltage is definitely 10x higher than it needs to be. That extra energy must be going somewhere... does the tube get unusually hot running like this?
Wow!!!
This I have to try! I happen to have a 20" TV that got recently retired from service. If I get my MG tube to lase, this will be an extremely cool experiment. So the flyback out is connected to the cathode and you're just waving the ground wire near the anode? Wouldn't there be some arcing?
