Hello, i was hoping some of you might still have saved a copy of one of the old time (late 1930's i think) magazines "Popular Mechanics, Mechanix Illustrated, Popular Science" or similar (cannot remember which one it was) where they had a "How to build an x-ray machine from old ford coil" where they wrapped the base of a lightbulb in tin foil and grounded it and connected the filament to the secondary winding. They claimed you could see through your hand, Not sure if this was directly or using a camera to take a photograph but this sounds like a fun project.
(They sure expected people to have a lot of skills and patience back then, Most fabricators today with modern power tools would not touch some of the projects i remember reading about)
Kep, here's a link to one. http://www.noah.org/science/x-ray/stong/
You guys can find lots of things like this if you do a google searches. For this one I typed in "Xray Ford Coil" and got a lot of hits.
Kep, Here it is. I made one for my daughters class science project over 20 years ago. Didn't X ray much , but the kids loved the jolt they got touching things they shouldn't. Les
That was fast, Thanks. But the little print thing there does not say if it requires photographic film or if the bones become visible to the eye.
So many possibilities for testing things... but first i would need to find a source of film since everyone went digital.
This is much like the xray glasses we could buy out of the comic books, it does not produce any xrays, it produces a very bright light, and you can see the bones in a hand when a very bright light is pass through it because flesh is not opaque but rather translucent, This makes for some fun with the small LED lambs and a small battery, as you can light it up and insert in into you nose and make you nose glow like Rudolph's.
Made one was I was a kid. Electron beam in a vacuum slams into aluminum foil producing ultra violet light and X-ray particles. You would need a photographic plate to expose to take a picture of your hand with. An old radio tube fixed up the same way produces more x-rays then a clear incandescent bulb.
I missed the foil part, that would have to be awful bright light to go through foil. It is a bit hard to believe that x-rays could be produced this way, but I suspect they are very weak, or the astronauts would have had problems in their aluminum foil containers in the vacuum of space.
