The first project he tackles is an automatic desk-clearer. This would come in handy all those times you need an empty desk right now and don’t care about breaking everything you own. You know, like when you inadvertently find yourself in a romance movie and the action is about to start. Reeves built that one with a pneumatic actuator and a few 3D-printed parts, and it works just about as well as you’d expect. Fun!
The next project was one every maker would love: a literal hot glue gun. Are you tired of your hot glue gun just lazily oozing viscous goo onto your project? This pneumatic hot glue gun built around a CO2 BB gun literally shoots globs of glue with 65psi of compressed air instead. Efficient!
The final build is a robot that dumps water onto itself — for some reason. Obviously, this is a one-time-use type of robot. It has a cup of water sitting in a pivoting holder that’s actuated by a servo, which is controlled by a microcontroller development board. Push a button, and the robot pours the cup of water on itself, and self-destructs in the process. Practical!
