The Rotapult

This is the most demanding catapult machine design I've attempted, to date. That it works at all, much less very reliably, is fairly astonishing. For physics buffs, note that the throwing arm is aimed almost at a tangent to the circle of rotation. Very tricky!

This is marvellous. When the camera was spinning filming the cone, did you have to recalibrate the whole machine?

You are a genious of the superfluous!

[BLitwin]

Thank you!

I had a rig, which put most of the camera weight on the center post. So, there was very little interference with the mechanism.

hey can u send me blueprints or plans to some of your,s recent projects would love to use them for me ideas i gust and help u help me kinda way care to share? @BLitwin

[BLitwin]

Sorry. Homey don't play dat.

[Khal337]

put a string on that baby and it'll be an automated ball-in-a-cup.

[BLitwin]

Oh geezis! Now look what you made me think about! Curse you curse you curse you! 8^D

Medieval doomsday-device?

[gunder71]

I love these... can they be bought?

[patrickcorliss]

Soo hypnotic !! Mesmerising.

I just can't resist looking at such accurate catapulting devices! So much, that i've built one myself! Yours is a little more impressive, though! :O

[LapisLee]

Awsome. Da Vinci would be proud.

[inr21sevier]

this could be a time machine a long shot but uh scence thats copper make it magnetic propelled to spin very fast and instead a ball or wait make it a laser or laser/ferrofluid magnetic pulse oiltoner+vegetable oil = ferrofluid/magentic liquid ha try that one hehe. @BLitiwn

[stephendijoseph]

freakkin awesome ..can i use this rhythm? Brad that is just incrdibiible!!
