E-Wheelie: wheels and motors

[webby1234]

I am looking forward to starting this project.

I am having problems finding suitable motors
and wheels any suggestions of suppliers out there?

Can this kit be broken down and purchased piece by piece? So, I may be able to afford your genius. How about a set of prints?

At least the PCBs should present no problem if you want to make most parts yourself. The PCB artwork files can be downloaded here:

and with

http://www.elektorpcbservice.com/

you should be able to get unstuffed pcbs. Sourcing the electronic components should be simple (RS, Digikey, Farnell etc.). For the motors have a look here, for example:

hi
i was contemplating using 250w motors instead of the 500w types ..i guess it will be slower but will there be stability issues does anyone think? or will the s/w make the necessary alterations for less torque.??

as i cant afford the wheelie kit and cannot get the boards populated/part kit i am going the zzaag route....

pity the elektor looks nicer..i think elektor have been rather over protective and petty with this project i hope someone produces a part kit soon..

Afaik 250W motors may have insufficient torque. Maybe it will work well enough for people <60kg
I don't know this but I do know: The only way to test it is to test it
The firmware needs not to be patched etc. for this, because the realised feedback loop will work with less and more powerful motors.

250W motors work fine, I have built my own self-balancing scooter by using two 24V/250W motors, which works fine. I can reach the maximum speed about 9 km/h.
