Spring-powered grenade

If you have seen airsoft Claymore mines, you’ll know that they usually have a double mousetrap mechanism inside. Basically, the energy that propels the BBs is stored as tension in the springs. This is a simple mechanism that doesn’t require gas canisters. Throwable grenades, on the other hand, use gas canisters as the propelling agent.

3D printed airsoft Claymore

This is the most recent version of my airsoft Claymore. I had done four others but they were messy, unreliable, and difficult to build. For this one, everything was designed beforehand to the last millimeter. I’ve tested it a few times during matches and it works reliably. It has movement detection and throws BBs with

Electronic grenades on a rubber casing

While researching for one of my old projects, the electronic grenade (Part 1 & Part 2), I experimented with a very different design. Instead of 3D printing the enclosure, I tried 3D printing a negative and molding the enclosure with liquid rubber. To be exact, it was a pair of liquids that hardened when combined.

Bomb prop for bomb defusal and domination games

Reddit user PyroSpud has recently published a very polished bomb prop for playing various game modes, consisting of a few 3D printed parts and some easily available electronics. And he has made both hardware design and software available for download on his GitHub. The device is ready for bomb defusal games, in which the top

Sound grenade for Airsoft [Part 2: Electronics]

Let’s get started on the second part of the sound grenade build, this part focusing on soldering, programming and assembling the electronics into the enclosure. For instructions on how to make the 3D-printed enclosure, check out Sound grenade for Airsoft [Part 1: Enclosure]. I decided to use an ATtiny85 microcontroller and the Arduino environment because

Sound grenade for Airsoft [Part 1: Enclosure]

Commercial airsoft grenades have to be refilled with CO2 capsules every time they are used. This sound grenade aims to be more economical since it can be used hundreds of times on a single coin cell charge, although you will lose the realistic loud bang and the ability to throw BBs. It consists of a
