Soeks modified with SBT11A
Inviato: 08/04/2016, 21:12
Hello,
here my DIY project with a russian Soeks 01M Geiger counter with a external SBT11A pancake.
I think the SBT11A and SBM20-1 tube have almost identical conversion factor (little difference)
The DIY SBT11A case have a internal 900mAh LIPO Accu with charging modul, 3,7V to 5V voltage converter and a High Voltage SMD circuit board.
The SBT11A tube has a good Alpha sensitivity.
I can power on the Soeks Geiger with the extern SBT11A probe with internal LIPO Accu or with internal batteries in the Soeks geiger counter.
The switch on Soeks on/off internal tube.
See pictures:
