The MBX Report
Alright, a quick report before I disappear into the glow of a blue luxeon LED for a few months....
MBX worked really well for what it was (a glorified testbed built in two weekends), it was pretty lame in combat, as I spent most of the time adjusting the LED header due to the last minute hack to due to destroying the accelerometer before the event. It ran between 500 - 750RPM at various stages during the weekend and showed that it can pack a punch.
A brief list of things to do.
- move to two wheels - helps balance and spin up time, was only 1 wheel because of time restraints...
- more volts - after the event when I ran it on 12cells (39.6v) it was really kick ass, hitting around 1500rpm (but totally undriveable due to my current code limit of 1200rpm....)
- make it round - it ended up square because I built the thing in a day with what was laying around in the shed, next time it will be round for lower wind resistance, harder to jam in a corner and better for hitting with.
The future specs:
Armour:
3.2mm Hardox 450
Drive:
2 x 12v 340 Winch motor @ 33v geared 3.6:1
Electronics:
Spektrum + AVR ATMEGA168 + SSR + MMA2300D 250G Accelerometer
Batteries:
1 x 33v (10cell) A123 Packs
Weapon:
Translational Spinner, 13.6kg @ 1500RPM = Lots of Kinetic energy
I look forward to bringing a much better, combat ready version to the Ideas Festival. _________________ https://www.halfdonethings.com/
