First things first
For all the Star Wars Fans
May the Forth be with you.

On to more mundane things the speed controllers in Gabriel are coming on. the big problem is the continual lack of space for the Roboteqs

As you can see I have had to stack them one on top of the other and pack a lot of wires between them, the problem was I designed Gabriel for a Wotty but these came up cheep so plans changed, as you can see there is now 2 links one for each speed controller and associated LED.
I still have to find room for the RX and the V-tail mixer, yes things are that tight! but by the end of the week I hope to have this part of the modifications done. leaving the modifications to the wheels to provide them with a crude torque limiter in the hope this will spare the drive gearboxes.

With regard to the BB8 project
I have ordered most of the basic drive train.
the Wheels, hubs, motors, speed controllers (all 4 off). Also the mixer the RX I am planning on using a 3s LiPo around the 3-4 Ah. the motors will not draw much more than 2A when stalled so this should drive the thing all day! the chassis will probably be Polycarbonate, it's strong and I have lots.
I am probably going to build a "flat floor chassis" first to test run the innards before I do the unit for the ball, in the ball the motors will have to be inclined at an angle to accommodate the curve of the sphere.

Still not found a suitable sphere for the project so Keep looking 20" or 500mm diameter is the target plastic preferred Polycarbonate or any plastic that can be painted 5mm thick split into two.

Hi yes I've been following his exploits from the very beginning video on utube with regards to this. he said in the second video it's not how the Disney one works!
He is using an inverted pendulum method I like it, but it isn't how the one used in the film works this is commonly agreed that it uses the "hamster ball" method with omni wheels unfortunately no information about the robot will be released before the film in about 6 months time. So everything is guess work but all the r2 builders agree on this point.
this was discussed on this thread in May I think, interesting project though.
