Powerful Nerf Blaster Aims To Fire 100 Darts Per Second:
Nerf has made plenty of fully-automatic blasters over the years, but their toys typically lack punch, precision, and fire rate. [3DprintedLife] set about building a blaster to rectify that last shortcoming, aiming for design that could fire 100 darts per second.
The design uses half length darts which tend to fly a little nicer from high-powered blasters. It fires them using belts driven by powerful motors, similar to wheel blasters. The darts themselves are loaded into a drum magazine which has sliders to push the darts into the wheels as the drum rotates by.
It all sounds straightforward enough, but getting it all working in harmony is a challenge-particularly at a fire rate of 100 darts per second. The build video explains the trials and tribulations involved in getting near that fire rate, with darts getting shredded and magazines throwing out parts along the way. A good helping of iterative design helps get everything playing nice, with the darts neatly leaving the magazine and flying downrange at great speed. The slow-motion videos of darts flying out of the blaster in rapid succession are a special treat.
I found the embedded YouTube video to be amazing! Just the right match between exposition of the various steps in designing and debugging the gun!
Update:
Upon further reflection: how long does it take to reload? Hmm?
