Review: Super-easy build, well engineered software, and a good case - I bought this primarily so I could keep a running graph, and so this product's serial-port support is what appealed to me. It's a simple build, with pretty much everything through-hole, and aside from the usual misery of identifying resistors, it was a quick, straight-forward build that just worked. I was somewhat disappointed in a lack of any debugging documentation. I've done other kits that would require you to test portions of the project before cutting a trace or installing an expensive IC, and this one didn't have that. You just stuck it all together and only after it didn't make ticking noises would you know something was wrong, and then you'd have few indications of where the problems were. Are you able to check TP2 before installing the tube? (I think you could test with just the 555 installed.) What should it read? Are you able to check TP1 before installing the ucontroller? (I think so, but I'm not sure you could do it with just a multimeter.) What should the blue pot actually be set TO? (Mine puts 202VDC on the TP2.) Despite that, I'm quite happy with the result. I especially recommend hooking it up to a serial port, where it keeps track of actual numbers -- uSieverts/min if I recall correctly. Also, the entire project is open source and open hardware. I was able to answer a number of my own questions just from the documents provided on their site. For the curious: You can power it off a 3v3 FTDI usb serial adaptor. Run power and ground to pins 1 and 3 of the 'pulse' header, and run the TX/RX wires to pins 4 and 5 of the 'serial' header. You're going around the power switch, so it will power up regardless of where it is set, although you should leave it turned OFF since it will otherwise be feeding power to the batteries. Or better, remove them entirely. It defaults to ticking for pulses on power-up, but you can probably reprogram the ATTINY with Arduino tools, although the code is raw AVR.
Review: Great for my continuous radiation monitor project - This worked great. I modified it to run on 5v and added an LCD screen and put it into a box. I made a YouTube video on it (called “Desktop radiation meter with mighty mohm kit & arduino” and “Modify MightyOhm Geiger counter kit to operate with arduino & I2C lcd screen” Been running for a few weeks now and seems fine.

## Questions & Answers

**Q: how many rems is the maximum this device will detect? 6rems a day and no problems according to cdc, so hopefully it goes to 20rem.**
A: The sensitivity and working range are a function of the Geiger tube that is used with the kit. The included SBM-20 has a working range of 0.014 - 144 mR/hr according to http://www.gstube.com/data/2398/

### ⭐⭐⭐⭐⭐ Great assembly instructions (1 hr) worked right out of the box
*by P***H on April 13, 2022*

Was too excited to get to soldering, it took me about an hour. I normally expect kits to be missing parts, but this had every last one of them. Pros: * it's open source, AND has programming pins * It has serial port pins (outputs clicks-per-second and a rolling uS/hr) * Has a button to mute the speaker (only the LED will flash) * Instructions are perfectly clear, great hobby project for kids * also has a "pulse output" pin for attaching your own logic Cons: * some might want printed instruction, but it was easy enough to find them online * would like to see the case be a full enclosure, but this is pretty good
