I dont think so, im not sure if the flexdrive is like the rckstr but if it is iit will turn the extra voltage into heat. Btw can you give me a link or something on where to get those aluminium things or something copper cause i need it badly
thanks
thanks
well i don't know if that link is useful for you since you're living in Sydney.
Why not try your local hardware or machine shop, or Google for: aluminum pulleys, maybe Google van help you out.
Back here in Holland, we have some local hardware shops specialized in profiles in all sorts of materials and sizes, like iron, aluminum, stainless, etc. I'm sure they have in Sydney some similar shop in your neighborhood

@LaZerZ:
you'd think so, and quite rightfully. Problem is:
1. If you slip with the Multimeter leads and break contact while the driver is being
powered, the Flexdrive can very easily be damaged, being powered without a load on it.
2. Even if you make sure that contact is good all the time (solder the DMMs probes to the driver),
the DMM doesn't simulate the voltage drop of the real diode, and so you end up
measuring a current that is different from what it will be once the diode is connected.
Effectively, your measurement will be inaccurate, you will have set up the driver with a "wrong" current.
The difference might not be much, but when you try to push the diode to it's very edge,
it could mean the difference between a happy diode and a dead diode.
Well said, mate.
