"Only those wheelchair guys don't tell you about the accelerometer chips that are Kalman filtered with those gyros to obtain a low drift angle. Check out some of the balancing robot projects online and you will see what i'm talking about.
Take a look at this one: http://www.tlb.org/scooter.html "

Hi Hardyus,
Thanks, Yep had been at http://www.tlb.org/scooter.html a while back. It seems that the wheelchair source in the pic is not associated with the "scooter" source. Also, Johnson & Johnson is the parent company of that wheel chair project.
I found the wheel chair, and the Futaba link posted in the applications links on the gyro chip site http://www.spp.co.jp/sssj/silicon-e.html indicating the chips come from them.

What I am really looking for is a good board design, component list, and programming for dummies....seems like the prices at http://www.tlb.org/scooter.html are a quite high ( 1 axis $150 )? for a DIY project?? and I can't see what sensors they are using.

It also appears that the chip from http://www.spp.co.jp/sssj/silicon-e.html outputs 3 axis from the one chip???

Update..
I e mailed them and received this response:

No results as yet from the UK.

Those with interest, and with better credibility, than I, are welcome to follow this up. I am quite ignorant in the lingo of this field. In these component sourcing efforts perhaps we could get a leg up by forming a "professional project group" image??

Cheers,
John
