Simple DIY Gamma Ray Spectrometer PMT Project

25/05/15 Simple DIY Gamma Ray Spectrometer PMT Project
Gammar Ray Spectrometer is a nuclear physics tool that intended to measure the distribution of gamma photon energy. The professional grade spectrometer can be found in nuclear research laboratory, geochemical and astrophysics institutes. To make my own experimental isotope identifier I purchased russian old stock FEU-31A PMT tube and NaJ(Tl) crystal. read more...

Geiger Kit selection guide

http://www.rhelectronics.net/store/how-to-select-diy-geiger-counter-guide
Want to buy a Geiger counter kit from RH Electronics, but don’t know what to choose? This short article should help you to select the kit model from our stock. It also has several general answers for the questions people usually asking before they buying a Geiger counter.

SD Logger+ Add On for MyGeiger

We released LCD Shield with SD Logger+ add-on for MyGeiger kit. SD Logger+ LCD Shield has same dimensions as the regular MyGeiger LCD Shield. Instead of TRRS audio socket it has micro SD card socket and TQFP-32 Atmega-328A processor with preinstalled Arduino boot loader. 

Because most of the operating time Atmega328 enter idle sleep mode, the power consumption of whole MyGeiger kit is still stay low as before. SD Logger adds only 1.5mA-2.0mA to the total kit consumption. When serial data is transferred from the main PIC18F2550 uProcessor to the USB output, Atmega328 enter active state for several micro seconds and writes same data to the SD card. If SD card is missing, or if you do not need SD log function, you can power down SD logger by removing LOG JMP jumper.
