DIY Geiger Counter Kit 1.1

October 4, 2015

This is an Open Source Digital Radiation Dosimeter, that can be used both as a portable detector, but also as a monitoring station to upload readings to the uRADMonitor network. This project is an update to the previous Geiger Counter Kit 1.0. When used as a portable detector, readings are displayed on the LCD. There is also a speaker that beeps on radiation events or is used to sound an…


ILI9341 touchscreen LCD Library

July 23, 2015

I got a few QVGA LCD’s with resistive touchscreen for an ongoing project. All that was left to do was putting the driver code together. The LCD code part was very much similar to my previous work on the ILI9163 but this time I went for faster SPI communication (also due to the bigger resolution). The microcontroller – an Atmega128 – uses normal SPI transfer and the external quartz crystal…


DIY Dosimeter Geiger Counter KIT1.0

March 8, 2015

Note: there is a newer version of this project, KIT1.1, see it here If I was to give this project a version number, the closest match would be the uRADMonitor model B. Finally an open source compact radiation dosimeter, that has an LCD and thus allows mobile use, but also comes with an Ethernet adapter so it can do radiation monitoring (uRADMonitor compatible). Yet, this is not quite the uRADMonitor…
