Well.

It's done.

It has a power switch, a nice quality BNC connector and it charges via Micro USB. My coding skills also seem to be not too shabby, since it hasn't acted up yet, and the values seem to agree quite nicely with the Gamma Scout.

Also: 

Probes!

The grey box is a pancake Alpha-Beta-Gamma probe, using the SBT-10A tube.

I'm still waiting on an adequately long BNC cable. This one's too short, my other one's too long.

Handle's made from a piece of Heat-shrink tubing. The biggest and thickest one I had on hand. It's simply glued to the case. I don't think it's going to stay put for long, but if it breaks, i'm going to figure out a better, comfier handle. 

The small silver probe is the High Dose probe i've made. It is based on the SI-3BG tube, which goes up to 300 Roentgen per hour (open reactor core levels).

That's about it. 

Hope you like it
