Comparison of dosimeters

Like with all measurements, it will be very hard to find two different devices indicating the same readings, especially when we demand increased precision. We now know that there are no such things as absolute time, absolute space, there are no synchronous clocks. It is the same with the absolute measurements, and in some cases it’s becoming more relevant to observe the change: if we see increasing values, we know…

DIY Dosimeter Geiger Counter KIT1.0

Note: there is a newer version of this project, KIT1.1, see it here If I was to give this project a version number, the closest match would be the uRADMonitor model B. Finally an open source compact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…

Atmega8 UDP Client

As a follow-up to Radu’s Atmega8 and enc28J60 for ethernet support article, I used the libraries to implement an ATmega8 UDP client using ENC28J60 that broadcasts a simple “Hello World” message over Ethernet. Circuit Diagram is exactly the same as simple web-server project(take a look at Schematic&Docs in the project folder). Do not forget to connect CS to PORTB2 if you are using Atmega8 and modify CS pin section in…

Atmega128 Voodoo

Apparently I had no better inspiration on how to name this post. It all started with a nice sunny day, when I was in great shape for doing creative work. My plan was to do some research on the following uRADMonitor models B/C, to put everything together and start the design of the new device. With all the extra new features, it was clear I needed a microcontroller upgrade, from…

Tube: SI-22G (CИ-22Г) Sensitive Geiger Muller

Pictures: Details: The SI-22G is a highly sensitive hard beta and gamma radiation detector tube, made in USSR during the 80’s for the Soviet Military Needs by the Soviet Institute for Scientific Radiation Technology Research. Notes on sensitivity: This is a highly sensitive tube, thanks to its cathode material and relatively large size. It is perfect for monitoring equipment and DIY dosimeters, superior to the SBM-20 in this sense. The…

Infused™ project

Infused™ is about passion for design, music, digital, programming and alternative culture in Timisoara, Romania. Structured as a set of interviews with people involved in the act of creation regardless of its final form, the first video covered Flat UI & Minimalism, featuring Madalin Gageanu and Adonis Raduca: I was excited to get an invitation to participate to the second episode. This time the subject was focused on Android software…
