Why are you using a brushed motor for the spinner rather than brushless? I would have assumed brushless would be lighter/more powerful?

Re: Another New Nanoweight...
Have a look at this page: http://en.m.wikipedia.org/wiki/Balancing_of_rotating_masses Your blade is statically ballanced as you have the centre if gravity on the motor shaft but it is not dynamically ballanced due to the shape of that blade. I think you could fix this by either using a simple rectan...

HDPE sheet
Hi, I've been trying to get some thin HDPE sheet (around 1-2mm, maybe one of each) but can't find anywhere to get it from.

Re: Peter Wallers Robot Ramblings
Oddly enough I am trying something similar but with a plain ring and a friction drive rather than actual gears. If I can get it to work in time it will be at the next AWS

Re: 2g) Any system involving the use of pressurised gas or l
Hi, I've been thinking about this and wondered if we could use propane as a gas? It could be stored in a tank as a liquid allowing for large volumes of gas to be stored in a small space allowing for an increased number of flips yet the tank would still be at a relatively low pressure ( around 130PSI...
