Night Vision Scope From Scavenged Parts 177

Posted by timothy from the see-in-the-dumpster dept.
Caydel writes "Greg Miller appears to have built a Night Vision Scope out of an image intensifier tube, and parts he found mostly in dumpsters. Also on Greg's site: Flyback transformers, coil guns, plasma globes and Tesla coils made from dumpster materials." You get the feeling he's not also writing product safety manuals on the side.

        He also has developed some kind of material that resists heat and is really light that you can paint on and is really strong. He figures that if Columbia had been covered in this stuff, it would have survived. Not sure what his background is but you get the impression that what he makes he shouldn't be able to.

    Is misplaced. I went into science because we had a superb physics teacher in high school (he'd left a job as a research engineer basically because, I think, it was too limiting, and he ended up as the schools science adviser for the council.)

    Among the stuff we used to work with were high voltage induction coils, the odd home-made low pressure gas discharge device - a good way of checking your vacuum technique - low power radioactive sources for playing with simple cloud chambers and trying to deflect alpha and beta rays with a watercooled electromagnet - and extracting short half life radionucleides from samples of yellow cake. (I did have enough sense to know that you don't breathe thorium oxide dust and that you handle uranyl nitrate carefully.) That and getting a signal big enough to light up a small bulb across the lab using a klystron. And he would let us get on with this stuff unsupervised - something about kids need trust in order to learn.

    Nearly 40 years later I am not only still alive but still building stuff, probably because those early experiences gave me the confidence to try things.

    Being quite ruthless, anybody who tries stuff around HV and microwaves and doesn't have the brain to spot when things are going wrong, probably needs to be removed from the gene pool anyway. And anybody who tries and has the brain and initiative to stick at it will learn something. We can't all expect to make our livings for the next twenty years by either recording not very good music and selling it for inflated prices, or suing people who actually have a business. Buying geek toys is no substitute for making them, and things that just go bang or send projectiles a long way are not the only way to have fun with physics.

  • I have heard that some of the early image-intensifier tubes had X-ray problems (often occur when you accelerate electrons to high velocities and they hit metal targets)...
    • While some X-rays are generated, unless the accelerating voltage is over 10kV or so (more than gen 0 image converter tubes operated at), the X-rays are of such low energy that they can't even penetrate the tube envelope. They would start to become a hazard at around 16 kV or so.
