Geiger counter with SBT10 tube w/ enclosure

I have recently devised CAD drawings for CNC machining openings for LCD LEDs, buttons etc. and SBT10 tube.

The result is a rather sturdy though portable Geiger Counter with a big alpha, beta, gamma capable tube.

The artwork is printed on the printable adhesive vinyl with a water resistant ink.

IR receiver for parameter setting is located the middle, below the LCD screen.

On the left there is a mode change button then On/Off switches for sound, LCD backlight and Power.

Connector for the SerialTTL<>USB connector is installed in the rear of the enclosure.

If you want one like this or just a machined enclosure please feel free to contact me.

Version 10.3c. adaptation for the LCD shield (v.10.3c.1)

v.10.3c.1 - adaptation modifications are listed below:
 PIN definitions are adapted to work with LCD shield as follows:
 #define SEL_BUTTON        11  (in v.10.3 was 10)
 #define ALARM_PIN          10  (in v.10.3 was 15)
 #define NULL_BUTTON    15  (in v.10.3 was 11)

simplified serial port output to work with freeware Radiation Logger software by radiohobbystore:
is now configured to be the default output changable back by menu (note: use of menu needs connection of IR receiver)
If you want CPM, [dose unit], Vcc to be the set as output format during the RESET_ALL (i.e. when the #define RESET_ALL true) find and change the line in Menu from:
back to:
