Gamma Dog Update: Gamma Dog Mini and substantial firmware update

Finally found some time to work again on the Gamma Dog. I have 3 GD electronics modules from the Gen 3 run and a bunch of detectors laying around so I decided to turn them in actual units and add improvements in the firmware.

New Firmware release - Current version is 5.6. These are some of the improvemets:

    - completely new sound library with harmonic suppression and advanced clicking capabilities for low frequency output

    - new "Meter" display mode displaying current rate vs. squelch level with adjustable "Peak Hold' feature and dynamic range adjustments. Fast response with refresh rate at 0.5 sec.

    - completely re-written and improved menu system that is bi-directional and with faster response

    - major internal restructure in the audio-generation routine

    - improved/fixed exit response of the "Open Squelch" Menu / Selector for Softkey / Volume selections

    - numerous improvements throughout the code and bug fixes

My friend Charles Young designed and 3D Printed enclosures for his line of Gamma Dogs. To make these usable with my electronics packages all I needed is to 3D print an "Adapter Collar" between my ABS Cap and his 3D Printed detector enclosure.

This is the enclosure for Bicron or Scionix-Holland 38B57 detector housing.
