Keep in mind that a transformer's noise is directly influenced by the load/current flow. If you are intending to use very little current (depending on your...
I recently sold some of my excess scintillator construction materials as a DIY kit on ebay, and will be mailing it tonight. Thing is, since the buyer might be...
Justin, Most of the magnetic field leakage from the transformer will be in the form of AC field at the switching frequency of the transformer driver. AC mag...

Ooh, just discovered another trick that should go down really well with this group - you can use K0FF's cut-open-the-v715-chamber trick (to make an kind of...
cool Justin! I hooked up my hacked 715 the other day an set it on the corner of the workbench. Mine now sports a zero center meter. Then I took 7 or 8 9V ...

yes I have eyed that b4. Usually the "wires" on these things are actually square copper tubing, and water is circulated for cooling. In practical terms, 144...
GM probes, like the ones on CDV-700's, all the different end-window and pancake probes work on the same principle, in which a radiation penetration causes a...
I had to toss in my nickel here. The "hacked" 715 will respond to DC ELECTRIC fields the strongest. Because of its slow meter response it is strictly a LOW...

Here's a thought. Buy an open frame, low voltage (6V, 5V, 3.3V?) reed relay at some electronic surplus place. Carefully remove the reed from the coil. The...
