Hey

So I picked up most of the parts on Friday afternoon to build the potato cannon. Unfortunately the piece of 40mm pipe that is to be used as the barrel is not perfectly straight. I also had to get a whole series of reducers, 110mm > 90mm, 90mm > 50mm, 50mm > 40mm. To solve both problems, I think I’m going to order a new barrel of 50mm, and ask them to ensure that it is perfectly straight. Using th 50mm barrel will definitely lower the projectile speed, but it does mean that I can fire larger projectiles.

I want to start actually constructing the cannon once I have all the parts I need. The PVC will also need to be cleaned properly.

I’ll keep you informed on any developments.

    I’m keen to team up with you guys at UCT next year to build a super sonic cannon :P

    Yeah we will see after this one. I’m keen on some other projects too, especially robotics. What do you think noosh? We could use a programmer..

    Me and Maya must still get together to fire this canon a few times. Just need some other piping…the guy gave me the wrong reducer, and I want a new barrel.

    Hey Eric

    Microsoft recently released v1.0x of their dedicated robotics software. Obviously, they trying to own the middleware market, but it sounds interesting.
