Perhaps they should have a vid of it shooting an arduino.

And he’s got his handy dandy… netbook!

85km/h? That’s not that fast at all, only 77fps. To put that in perspective, one can easily attain 150fps with a blowgun…

With a 3.5g dart you’ll get roughly 3.8j with the blowgun, with the theoretical 10g projectile you’ll get 2.8j with the coil gun.

It’s very nicely done and a neat project, but I can see how this is still a fledgling technology.

Exactly bigalexe,

The weight of the projectile is 10 grams. Compare that to a 1 gram bb or pellet’s weight and there is a big difference :)

As for the functionality, Its a work in progress. I update everything weekly and am planning on getting the Arduino control of the boost converter working soon. (I actually have the boost converter working already)

The biggest hurdle atm is getting the capacitor banks to charge individually and discharge individually :/

anyhow, thanks hackaday :D

paul, how about using a relay system to wire the caps together to become one large bank, then disconnect so that they are seperate banks?

Can you guys stop loading the article text with a million hyperlinks please.

….better idea..
shoot an arduino
WITH AN ARDUINO
the thing i hate bout that type of plastic, if you heat it even a LITTLE too much, it bubbles internally

re: your linked page, Fascism?! Seems a little strong.

Seriously I don’t know what to say about coilguns / magnetic projectile guns. Maybe the correct scale for these things is artillery-size, firing a several-pound projectile or larger.

But the more I look at these little proofs-of-concept, the less impressed I am with the whole idea: a bullet weighs more than ten grams, goes much (much) faster than 85 km/h, costs nothing, and can be accurately fired from a weapon small enough to toss in a pocket and cheap enough to put them in everyone’s hand who wants one.

plus at this size, you’re never going to get past the loss due to extra energy conversions.
