My apologies to everyone who has been waiting to place an order, it took a little bit longer than I expected to get all of the parts for this batch. I’m not sure if I’ll be able to keep up with the demand around the holidays, so if you’re thinking about giving a kit to someone (or yourself) as gift, it might be a good idea to order now.
Christoph sent me his data logs, which clearly show the effect of altitude on radiation exposure:
The red trace is the background level on the ground in SFO and hovers around 20 CPM. The blue trace is the measured radiation over Greenland on his transatlantic flight. The peak readings are 25 times the background radiation at sea-level!
I’m happy to announce the release of a custom laser-cut case for the Geiger Counter kit!
The case, which is made of high quality clear acrylic, comes with standoffs and all the hardware needed to assemble it.
The case includes access holes for the HV adjustment, the piezo beeper, and the mute button.
There are also cutouts for the battery compartment and the serial/ICSP/pulse headers.
A pushbutton switch with a 17mm long plunger is included with the case. This can be optionally installed in place of the existing microswitch S2 on the geiger counter. The long plunger makes the mute button easier to actuate with the case on.
