There are two versions available:

• Version 0.9 is the most simple, requiring the least number of components. It shows the level of radiation by using a single LED. It is powered with an A23 12V battery. You can interface it with Arduino and other microcontrollers.

• Version 1.0 has a strip of LEDs that gradually light up. It uses a more powerful, standard 9V battery. It requires more circuitry, we believe it is worth the result :-)

Using the Gerber files, available here:

• Gerbers for Version 0.9: https://github.com/CarlosGS/open-radiation-detector/tree/master/Detector_PCB_0.9/Gerber
• Gerbers for Version 1.0: https://github.com/CarlosGS/open-radiation-detector/tree/master/Detector_PCB_1.0/Gerber

This can be done with any manufacture method of your preference.

Full bill-of-materials are available here:

• BOM for version 0.9: https://github.com/CarlosGS/open-radiation-detector/blob/master/Detector_PCB_0.9/Documentation/BOM_open_rad_detector_0.9.pdf
• BOM for version 1.0: https://github.com/CarlosGS/open-radiation-detector/blob/master/Detector_PCB_1.0/Documentation/BOM_open_rad_detector_1.0.pdf

We provide manufacturer part numbers and a link to buy the parts in online stores. Use your favourite supplier!

• Version 0.9: schematic, PCB layout
• Version 1.0: schematic, PCB layout

• It is an experimental design, do not assume it will work in the first try. In doubt, ask in the comment section so we can document everything better.
• Have a voltmeter handy to test everything.
• You may need to tune the high-value resistors within the detector chamber. Do not solder the chamber permanently. It is better to solder two corners only, in order to test the detector first.
