Why wireless charging

To run the bGeigieNano as a fixed sensor for a longer period of time, it is required to keep the bGeigieNano charging at all times. Without charging the device the owner would have to remove the device as a fixed sensor and charge it manually. One way to charge the device, is to lead a cable to it. This will work if the device is in a safe location (inside for example), but won't work if the device is outside, in various unpredictable weather.

The Pelican case of the bGeigieNano is waterproof to keep the device safe. By wirelessly charging the device through the Pelican case, the owner of the device can not only keep their bGeigie safe but also easily take the device for a drive.

So the question is, how can we wirelessly charge the bGeigie?
