There are a couple of things that might prove useful bearing in mind when thinking about launching a high altitude balloon with the Muon Hunter.

In terms of ballooning, weight minimisation and power consumption minimisation is everything, therefore you can do a few optimisations. Attaching the kit to a Raspberry Pi in this case to save the data could be a sensible option, so this is the scenario imagined here. Check out how to prepare the Pi for muon logging here. However, there's much more you can do, check it out below.

The Muon Hunter makes datalogging very easy by design. The signals are like button presses, just much shorter and you don't have to worry about debouncing.

1. on the ST Micro connect Vin with the 5V input (JP1 on rev3) and

2. on the MH board connect the 5V power to the Raspberry Pi 5V output (JP4 on rev3). Or do the equivalent manipulations with jumper wires. Note: rev2 is connected to the Pi already except for step 1.

Install the pigpio module on the Raspberry Pi as described here: https://www.raspberrypi.org/forums/viewtopic.php?t=66445

In short issue the following commands in shell:

wget abyz.co.uk/rpi/pigpio/pigpio.zip
unzip pigpio.zip
cd PIGPIO
make
sudo make install

Then start the daemon from shell:

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:

• I2C based datalogging for the GM signals, too
• SQL data storage (SQLite3) with CSV export
• Database structure changed
• AVR records coincidences
  
• UI program revised
• LOG.py main datalogging script added
• export.py database to csv export script added

If you want to use this open source tool http://www.fischl.de/usbasp/ to program the Muon Hunter, here's a quick rundown on how to do it under Ubuntu.

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.

UPDATE.
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:
https://www.raspberrypi.org/documentation/installation/installing-images/README.md

We are going to program the ATmega168 microcontroller on the user interface board using the SPI interface on the Pi, so enable SPI. I mainly adapted this Instructables for the Muon Hunter kit.

sudo raspi-config

Version information
These instructions work with v0.1 and v0.2 of the Muon Hunter kit.

This guide is for those who wish to configure their own Raspberry Pi.
If you have a working Pi skip to Step 4.
