Hi guys, I wanted to know if its possible to use RCA jacks and plugs for the cdv- 700's probe without the risk of being shocked with high voltage. thanks! kev...
Not really, the centre pin protrudes too far for safety. The shock won't kill you but you might drop the counter, fall off the cliff ;-) etc. A BNC is the...
RCA phono jacks are designed for very low voltages. Although they can in theory withstand 500VAC for 60 seconds, I have seen them break down after a number of...

I am aware that RAD can fog photographic paper/film. I am curious though, would different KEVs expose color film uniquely - making different colors on film?...
Nope. The alphas, betas, and gammas just shoot through the visible dyes as if they weren't there, and it all looks the same. See my polaroidiographs at ...
I bought a pack of Xray film the other say to see if a fairly not granite spot will take an X ray. Thinking about using black plastic bags to make a crude...
