8:23 lol DuPont, they are hell... but a necessary evil

Awesome! ... ... Wanna try Mega Darts or vortex?

I think a lot of your problems with jamming at high speeds can be explained this way: When the dart leaves the magazine, it has incredibly downwards momentum. The more darts you're trying to shoot, the faster your magazine, the more momentum. Your darts are a flexible object, and you're only catching them at the tip with your launcher, so the momentum in the bottom is continuing, which then causes friction and jamming. This is also the same issue with the tips being brought upwards and angling strangely. This might be fixed by changing the angle of the drum, either making it horizontal to transfer the entirety of your rotational energy on release into forwards momentum, or diagonal to just cut down on the amount of energy that you're having to mitigate/deal with on the dart when it is released from the magazine. Custom hard rubber darts or solid darts might also solve this issue, but that doesn't seem like an option.

Important note about drone ESCs: Their current rating is based on air cooling. Without cooling, expect them to blow up even below that. And if your throttle signal is jittery as hell, they (or the motors) are gonna pop too

Yes! More! Perhaps, since you already have the rotating design working, you could make an RPD-style belt inside a drum the same size as your current drum, and make it belt fed? I don't expect it to be nearly as fast, but it would be a fun challenge

Time to create an automated mag-loader....dump the darts in a hopper and it sorts them to be the right direction and then feeds them into a mag....

9:25 I think a physical button on the bottom would be better than a servo

Teflon rails as guides to help them from catching and throwing them off bore? That it worked that well kicks ass.

Finally, I’ve been waiting so long for the update! So pumped!

I love DuPPa's I2C Encoder and I2C Encoder Mini because it solves all the annoyance with using interrupts to read the quadrature signal and lets you just read off an I2C register

When this came up on my feed, I thought it would be using Compressed Air, But this So much more complicated than that Kudos!

Why didn't you use wide GT belts for the belt drives? Widths up to 15mm are available. Perhaps they would have performed better at such speeds as they don't stretch as much. And if you turn them inside out, the teeth would provide extra grip. Also, a pair of flanged bearings with a regular bearing (or a spacer) between them would work great as a pulley in that case.

This is absolutely Amazing! I would love to get my hands on this! Great work!

Perhaps consider two belt stages. A slower catch belt feeding into a faster propulsion belt is how I've seen similar mechanisms work well before when the item is flexible.

I lol'd at "consumables." Great work!

@JeorgSprave over at the slingshot channel has tips on how to make a cheap and easy projectile catch. just need: -medium cardboard box -towel -box knife -tape (optional) -fold in or remove all but one flap around the opening -cut 2 slots into the side of an amazon box about 2 inches or 4cm apart perpendicular to the opening, on the side opposite the remainder flap, -slip a towel into the slots, draped over the middle bit (leave the towel on a hangar to stiffen if needed) -dangle the towels layers like curtains, passed the remainder flap, which you can tape up to make a basin to catch your projectiles that's it, takes 10 to make your first one, and I've made them in just 2min. you can also just cut one larger slot if you have a simple triangle hangar that's longer than the width of the box.

I hope engineering channels such as Stuff Made Here, etc. take on the challenge of refining your current design to work even better. After all, it’s only a matter of time before someone designs a blaster and mag that can do 1000 RPS. 😉

Here's an idea maybe an RC tank with any variety of strange wheels screws multidirectional drive and a mega dart launcher. The fun bit is some kind of overcomplicated and deliciously over engineered autoloader for the mega dart.
