The new rev2 boards have arrived. Nice job from the manufacturer. The order form will be available in a week or so.
A technical update (facelift) is coming out from the Muon Hunter ST Nucleo K8 version at the end of January.
Happy new year!
Have rev1, but want to have some of the new features? Read on to find out how to modify your kit.
The new firmware is out for the detector and so is the new python scripts for datalogging.
What's new? Quite a lot:

Download the setup and programs available for the Muon Hunter kit as a single Raspbian image onto a minimum 8 Gb memory card. It's based on Raspbian Jessie.
It includes the AVR programmer feature and the datalogging interface, too.
here it is (now ver v0.3). See v0.3 notes.
The installation instructions are exactly the same as the Raspberry Pi image installation instructions found here:
The latest firmware update for the MCU is available on git. Now it displays the total number of GM counts, too. Thanks for the feature request, Paco. :) You can switch between the averaging and the total modes using the MODE button, plus fixed 2 little bugs.
Read more for the instructions.
You'd expect more muons to come from the direction of the top of the atmosphere than from close to parallel to the surface of the Earth.
This initial data was taken with the highest aperture, so it merely shows the magnitude of the counts.
When the tubes were set parallel to the surface of the earth, I measured the following with one of the prototypes - look at the muons / hour data:
Nothing comes out of vacuum except for a few elusive particles, so this kit has its story, too.
Mine started when I was looking for a tool for demonstrations when teaching particle physics on a budget. Something that actually could do physics in this domain. The first thing I looked at was these cheap GM counters and started to think about turning them into a coincidence detector.
First I built a lead coincidence detector that detects electromagnetic cascades caused by muons at the end of 2014. You can check out this prototype here.
CODE examples are on GitHub
