@eldaria: I’m afraid not.

@urs: you need the following components:
3x Resistor SMD0805 1K
1x Resistor SMD0805 100K
2x Resistor SMD0805 1M
1x Capacitor SMD0805 100pF
1x Capacitor SMD0805 10nF
1x Capacitor SMD0805 100nF
1x Capacitor SMD0805 10uF
1x IC SMD MAX4466EXK+T
1x Electret Microphone 6×2.2mm like these: http://g03.a.alicdn.com/kf/HTB1Xj5.OVXXXXbTapXXq6xXFXXX1/Free-shipping-30PCS-6-2-2-Microphones-font-b-capacitive-b-font-electret-font-b-pickup.jpg

The components will need tweezers, soldering paste and a hot air soldering station. Careful not to damage the other parts of the board with the hot air. The circuit/pcb layout is as follows:

Excellent question.

A/KIT1/A3 compute CPM counting all pulses during every minute. Then they send the data online.

Assuming the radiation field would be above the background level, you would sense the source if the one-minute average would also be above the background level. But keep in mind the inverse square law, which leaves little detection space if your speed increases distance from source very quickly.

I’ll write it down in an equation if I find the time.

Hello Urs,

While this feature is not available, it is definitely worth some additional research. I will keep it in mind for a next firmware update.

Hello Wolferl,

Please see the files attached, and use them as a starting point. I am using CrossAVR over Eclipse for the AVR Toolchain, and the Makefile is auto generated.

This is great stuff, Wolferl, thank you!

I agree, we’ll have that in place once the notifications are implemented. As a first step, all unit owners received an account here. That account will be used for the notifications.

The code runs with errors:
[Error] TypeError: $ is not a function. (In ‘$(“#status”)’, ‘$’ is undefined)
downloadUnits (radiation-monitoring:325)
Global Code (radiation-monitoring:424)

You will need to add JQuery too, it is also in JSFiddle, top-left of the screen. But easier, here is what you need to add to the blog’s headers:
