Team Eventorizon: Build Diary

Had nothing but trouble with dimention engineering products, try with a rx battery if it still doesnt work..

Also, i thought you were using tz85's? They have a bec built in...

So, if I unplug the BEC then it should still work?
You guys have given me loads of things to try, so its just a matter of me working my way through them to see what works.

If your running 2 ESC's with a BEC and a seperate BEC you could have damaged something. Your probably OK but your best to get rid of your external BEC and cut the red wire to one of your ESC rx cables.

How do people slow there discs down. Binky's disc takes 2 minutes to stop from half speed cos of all the bearings. I don't want top remove the bearings as it will wear away at the supports. But I don't think driving into the wall is a legitimate breaking method?

I think i read about something like an electric brake on the riobotz tutorial. You might want to check it.

You could use a magnet to slow it down a bit- if you have a spinning piece of metal with a magnetic field going across it then it will slow down and be harder to spin. If you connect a magnet to a servo arm then you could engage this brake at the end of the fight.

you could use a bicycle brake pad on a solenoid or servo just to push against the side if its smooth to generate some friction to slow it faster

Or turn off disc throttle and just short the motor out. Same principle, just simpler.
Might want some load though to reduce current at the expense of increased slow down time.

The system is fitted with a one way clutch so that we can turn the motor off and the disc will still spin freely, but shorting the brushless sounds like a really bad idea.

It will probably boil down to a servo/solenoid and a brake pad as there is a nice flat ring running all the way round.

Kind of a pointless rule IMO, ring Grant / James and see what they think of the 60 second rule... i wouldnt fail a robot on tech check for it, and if there happy to run it at the event i dont see an issue.
