NEW and upgraded model of RH Electronics Geiger Counter DIY Kitver.2.00 RH-K-GK-2-Acompatible with Arduino IDE LCD Color: BLUE or GREEN, let me know the color you needPCB Board Color: BLUE or GREEN RH-K-GK-2-A Educational Electronic kit to drive Geiger tube ( tube is not included!)This is Do It Yourself Kit, you need to solder it. Have any question or need help to download PDF manual after purchase? You are welcome to contact me! This is upgraded version 2.00 of our robust Geiger Counter project based on Arduino IDE Atmega-328A, very easy and fun to solder project. All parts in the project are through-hole easy to place on the board with a solder iron. With your package you’ll receive detailed printed electrical circuit to assemble the board and we have technical email support if you need any help. Microcontroller comes pre-programmed with installed Arduino UNO bootloader and uploaded sketch, if you need to get program code please contact us after your purchase to get the link for downloading source files. If you want to add SBM-20 geiger tube to your order you are welcome to ask me for about editing your invoice. Optimized code and circuit of the kit has true voltage feedback on high voltage, that make this project much more stable for serious experiments where you need regulated high voltage and high speed counting ability. With a good quality Geiger Tube (like a new LND-712) you can test very active samples and get maximum count rate as your tube is possible to go up. The kit supports UART logging of CPM value and can be integrated into environment monitoring project. youtu.be/tEhwbNvi-Skyoutu.be/EHGymVbiv5E Technical specifications:High Voltage PWM Converter with true voltage feedbackHV Converter has ability to drive 20M load, 25uA into 500V max.400V and 500V Geiger Tubes are supportedDose-Rate Calculation and CPM counterNew Bargraph with CPS counterTwo tact buttons for controlling the softwareMoving Average CPM calculating algorithmUART logging with “Radiation Logger”, require USB-TTL dongleClicker Geiger Event Sound with Mute and Two LED’s Supply Voltage: 5V DCSupply Current: 15mA at background levelDimensions: 89(L) x 39(W) x 22(H) mmShipping Weight: 250grUPC Number: 634654895707SKU: RH-K-GK-2-A What is new in this version?Well-designed electrical scheme and improved PCB layoutTrue voltage feedback in PWM high voltage converter that allows now to drive 20Mega ohm load on 500VOptimized software for fast count-rate conditionSecond screen mode with CPS counterFast CPS bargraph with logarithmic scale (great for pancake tube or scint.probe)Native support of 500V and 400V tubes, voltage is set with jumper switchTwo LED’s with buzzer clicker and mute buttonSwitch between CPM or CPS screen with buttonThe kit is robust hardware that designed to drive a Geiger Tube while high voltage and pulse counting are controlled by one microcontroller. This is simple and educational project, however load capability and performance of the circuit allows to use this board also in more serious applications, like scientific research or extreme enthusiast tests. Second CPS screen mode with bargraph can be used with sensitive pancake GM tube or with externally connected scintillation probe. As before you have:Dose-Rate calculation and ability to calibrate through Arduino sketchMoving average CPM counterUART Logs of CPM value every 10 seconds16x2 LCD ScreenFriendly Arduino IDE source files, open source with buyer Measuring and adjusting high voltage: Default PWM settings in software should work fine for both modes: 400V or 500V. If required, you can adjust PWM percentage ratio through sketch update. The kit has installed 10Mega ohm load resistor with output on terminal block. When you apply 10Mega ohm voltmeter on terminal block then load resistor creates voltage divider with internal impedance of voltmeter. That’s why 400V will read as 200V and 500V will read as 250V. Maximum allowed load on 500V is 25uA – 20 Mega ohm total load. You can measure high voltage without any special dividers with your 10M multimeter, just remember to multiply reading by 2. Compatible Geiger Tubes: Many popular 400V and 500V tubes are supported. Default software settings of gamma dose-rate are for SBM-20.If you struggle to deal with Arduino IDE sketches please let us know when you purchase in PayPal comments of your order and we’ll set the gamma coefficient for different tube you have. Usually the coefficient can be extracted from tube datasheet, in the PDF manual you can find the most common values. Some old stock tubes hasn’t any useful dose-rate conversion information in their datasheet, in that case we’ll use default SBM-20 settings. The kit supports following GM tubes: SBM-20, STS-5, SBM-19, LND-712, LND-7312, SBT-9, SBT-11A, SI-180G, Philips 18504, Beta-1, Beta-2, Gamma-7C, Vacutec-70019A and more. We tested the kit with LND-712 new tube and DP-2 Sr-90 source back to back where maximum CPS reading was recorded is 5000 CPS (300K CPM on LND-712). The DP-2 Sr-90 test source is known as one of the hottest test sources that usually cause old stock tubes like SBM-20 to ignite and enter current mode. That’s why if you planning to run the counter in extreme condition please be sure you have a new quality GM tube that able to work on it’s maximum count-rate. The kit can be pleasure to solder even for a beginner. Electrical circuit design made simple and clear as possible. If you need assembled version please check my other items for the assembled version of this board. Test video demonstration of the assembled kit with one of the highly activity DP-2 Beta test source and LND-712 tube. The counter stay very stable and do not drop readings like competitors devices!
