This is the first part of my project of building a 100% automatic motion sensor claymore mine for airsoft purposes. The design is similar to other 3d printed mines, however I've improved some reliability issues.
The mine itself has a safety (the firing wont move unless you disengage it from safety position) which means that you can load and store them in your backpack.
You will need 2x standard rat traps for the springs, 4x cable ties and some tape.
The second part of the project will have a module containing an arduino nano (or any other clone), a motion sensor, a buzzer/LED, an IR receiver and a servo motor (10-20 Euros approx. total). The module will stick to the back of the mine and will convert it to a motion sensor mine. So far it's working perfectly.
The MKII and the full programming code/wiring diagram/links to the components/unmarked files will be available only for purchase or tip. If you are interested please comment.
Please consider, if you like the desing, to donate to the developer.
