This is a remote controlled, motion sensing, BB throwing airsoft Claymore that I developed, built and used on my own matches. I'm releasing its design on the hope that other makers can enjoy it.
More info and some videos @ https://airsoftdiy.com/3d-printed-airsoft-claymore/
- A doble mousetrap mechanism that shoots BBs forward.
- A motion sensor that triggers when an enemy (or a friend, or you) walks in front.
- Flashing Led and loud piezo in case the victim doesn't realize what hit him.
- A button on the backside to open/close (short press) or activate/deactivate the motion sensor (long press).
- A remote controller with these functions (note the bold initials, which correspond to the remote buttons):
- Activate the motion sensor.
- BOOM -> Immediately opens and shoots the BBs.
- Check range -> Flash Led. Useful if you hide far and aren't sure if the signal will reach. If it's too sunny to see the Led, a long press will also trigger a sound.
- Deactivate the motion sensor.
- Works on 4xAAA batteries. Very long battery life. While it's not opening or closing, it sleeps and only consumes a few microamperes (even while motion sensor is active).
- Easy to print body. All parts have a flat surface and need no supports.
- Most of the structural integrity comes from 3 internal wood bars. Otherwise it would literally self-destruct due to the force of the rat trap springs.
- Easy to solder PCB. Most components are big and through-hole, with a couple SMD resistors but they're still relatively big.
At the moment there is no step-by-step tutorial. If you wish to build your own Claymore, you need to be familiar with:
- 3D printing stl files
- Manufacturing a PCB from gerbers (as in, sending it to a fabhouse)
- Sourcing and soldering electronic components (most are very basic, but ask for help if needed)
- Loading an Arduino program into an ATtiny84 (I recommend using an SPI programmer, since I put a connector on the board)
If you want to modify the enclosure and the PCB, you’ll also need to use Solidworks and Altium, respectively. The firmware is developed in C++ on the Arduino IDE.
