Review: Geiger counter kit - Easy kit that is a good tool for hobbyists.
Review: A super fun kit with seemingly great accuracy - This is a super fun little kit to put together. While you can download the BOM from MightyOhm and source the parts yourself (I've done both), the pre-selected kit makes it a bit easier to avoid parts that won't fit, or other small issues. The sensitivity of the SBM-20 tube speaks for itself, and easily outperforms may other tubes. If you're starting from scratch with a blank ATTiny 2313V (not the pre-programmed unit that comes in the kit), you'll need a simple debugger and Microchip (formerly Atmel) Studio. The simple firmware can easily be modified, as there are a few improvements off the bat that can be made. Regardless, this is a great kit that you'll enjoy putting together, and if you want to take it a few steps further by modifying the firmware, you'll have fun with that too. I've connected mine to an ESP8266 for an internet-connected counter, with integrated level alarm. It's fun, works well, and allows for IFTTT integration. Yes, this kit is more expensive than pre-built kits on eBay that do the same thing, but you'll have more fun and get a better tube. Highly recommended!

## 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
