@ryanpallesen3569 26 дней назад

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.

@3DprintedLife 26 дней назад

You're exactly right, the darts are moving at nearly 7m/s when shooting at 100/s rate. And they have around 2-3 ms to change directions and extract from the mag, then

@sharkbyt8806 23 дня назад

@@3DprintedLife I wonder if you could use a harder, thinner dart in order to counteract this issue. I don't have the resources to try this but it would be cool if someone did. The downside is that they would hurt a lot.

@@3DprintedLife I wonder if you could integrate the mag and the feeding belts more closely. right now there a lot of space between them and they don't really join together. maybe you could somehow make the feed belts mesh with the magazine by having cutouts in the mag for the belts to sit.

@paranoidzkitszo 17 дней назад

What if a "force" was added from the back? So, the dart isn't just snagged, dragged, bagged, sometimes making it, other times just causing ones' self to go mad- what if a slight flow of air was being generated by a fan from the back to kinda push it along especially at the higher speeds so that it's not just the front of the dart being grabbed by the shnoz and dragged into criticall velocity like a brat child getting caught stealling by thieir moms at the candy store/ toy store....

@marekfiferna 26 дней назад

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

@3DprintedLife 21 день назад

Yeah I expected the heat from not cooling them, but they only run at high load for a few seconds tops so shouldn't burn out. I did discover a bad signal would kill the esc's haha but that was resolved by switching to the teensy!

the servo allows it to be a smart-blaster, and eject the mag as soon as its empty. which isnt practical but does add cool factor. pretty sure this design does allow for both the wedge and a pull-tab at the back for manual ejection. id be suprised if this isnt already in the design and just not covered.

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.

@Demonanimator 21 день назад

In my opinion that is a very narrow barrel those darts are expected to pass through, which may be why they sometimes get jammed in the flywheels. The narrow barrel space may also be causing dart drag, which may be why your darts aren't traveling straight when fired.

@nanastos18060 26 дней назад

@ironbeagle1610 21 день назад

this is such a cool design. once you get it flushed out you should definitely order a custom PCB for it so you can make the body slimmer and integrate everything better. also one suggestion is to make the mag release purely mechanical, while the current design with the servo is really nice, a mechanical one might take up less space and have less weight.

@billymarmalade3263 18 дней назад

instead of a spring system, could you use centrifical force to bring the darts to the outside of the mag? youd most likely have to make the channels for them straight though.

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. 😉

@Gunbudder 2 дня назад

why not go to track fed like a real minigun? they have to use a track that rounds slide on because any other method is too slow or unreliable for feeding. and you don't need extra barrels either like a real minigun does because your barrel doesn't factor in to firing a dart at all (you aren't even using gas expansion to move the darts). i'd move towards a huge carousel that feeds a track into the "action" of your two belt drives, and then a rotating pawl that grabs darts from the track and puts them into the belts, then moves out of the way (exactly how the minigun's action loads). what you have now is like if you deleted the track and the loading system on a minigun and just threw rounds from the carousel into the open action lol

@Forakus 26 дней назад

For the darts going all over the place, you should put a bcar. A bcar is a type of barrel addon that acts like rifling.

@siberx4 26 дней назад

These generally don't work that well on flywheel-based blasters; they rely to some degree on the air pressure of a typical spring-and-plunger arrangement pushing them from behind to ensure the darts travel through the bcar reasonably straight and don't lose too much velocity doing so.

@shatteredskies191 26 дней назад

⁠⁠@@siberx4they work fine on flywheel blasters but are a bit more touchy. On a springer, you usually have air ports before the bearings, so that’s not relying on the air pressure either.

@maweitao 25 дней назад

@@shatteredskies191Air pressure is not a factor in flywheelers; the only thing imparting momentum is the flywheels themselves. It's why the only marginally effective BCARs sit just ahead of the flywheel cage. Good dart alignment is one reason, but the bigger issue is that anything ahead of the dart, be it bearings or the barrel is doing to drop FPS. Springers, on the other hand, are entirely dependent on air pressure. It's why barrel length is an important component. It's so much of a factor that muzzle blast can disturb a dart's flight path and that's why some BCARs are ported.

@shatteredskies191 25 дней назад

@@maweitao correct. But anything after that porting on a springer will also drop fps. All I’m saying is that bcars can be used effectively on flywheel blasters.

I have a question, why didn't you use rubber belts on the belt drive? I don't remember if you explained it in a past video but I feel like it'd be a good idea compared to plastic, also with rubber belts you could have a very small belt side loaded into the drive to get rid of any problem with the belt expanding when sped up. Also for the jamming problem I don't know if it would help but you might be able to have a tube barrel with cut out sides for the belts instead of a open space where the darts can stray off the wanted trajectory, also another person has said the centrifugal forces of the rotating drum might be your problem, but I think this might be the solution to said problem.
