Loop the Loop Project Night

NortHACKton met this evening at our new NSME facilities (http://www.nsme.co.uk/). The club house was pretty much perfect for what we needed, we made good use of the projector and it was nice to have tea and coffee on demand. As most of us drive and don’t drink anyway it seems to suit us well. From now on we will probably meet there twice a month, once for a project night and once for a lecture night, after the lecture we can probably retire down to the Malt shovel anyway.

Back to this evening anyway. The idea was to build a loop to drive the remote control car around. This is a precursor to any potential wipeout track we want to build for the Maker Faire. We previously had a 3D model for a loop made in paper so this evening was about scaling it up to a useable size. This was also a key factor that we needed to test in order to make the large spider bot. We used a projector to shine the pattern onto sheets of cardboard so we could draw round it and cut them out at the appropriate sizes. A team of cutters and some people drawing and we had all the bits we needed cut out and ready for sticking. More team work ensued with one man on the hot glue gun, one folding and holding tabs till the glue dried and a third pair of hands to feed the card in and we were done.

The whole project was a testament to teamwork. Many hands managed to get the whole pattern cut and assembled in 3 just hours.  The only real disappointment is that the loop was too big and the poor little car couldn’t actually complete a full loop. Time was drawing short so we bundled up the loop and stuck it in the back of the car. I will modify the loop making it smaller and we can try it again. Anyway the evening was a still a great night, and despite the lack of success I’d definitely do it again.

  1. The speed the car must be moving at is roughly equal to sqrt(10*g*R) where g is the gravitational constant and R is the loop radius. For a 0.5m radius loop, this gives a speed of around 7m/s.

  2. Hi guys looking for a hackker space to help with a cappasitor problem i have – couldent find a link on NORTHackTON so this looks like the only option

    Cheers

  3. @MR WILCOX, you’re after the mailing list link on the right hand side of this page

  4. Yeah we should have done the maths for the loop, but we were lured by Youtube videos showing it’s possible. In retrospect, they are probably for the car with the faster motor option and LiPo battery, which will probably get you 7m/s. I don’t think many people would be able to control it at that speed though.
