Step by step I am building my CStimer project.

Here on the picture you can see first device from this project.

This detector will let airsoft players to find a 'bomb', and stops timer of it as soon as detects presence of a 'bomb'. 

Next I will start to build main device of this project - the 'bomb'. Now I am waiting for one spare part. And as soon as I receive it, this project will go on again :).

If this project was interesting for you, you could buy me a cofee :)
