Where do I begin?....

• Small Right Angle brackets (not those goofy easily-bent gussets)

• Small 3-sided Corner Brackets

• 4", 5", 6" Axles

• A way to lock a clutch, motor and axle together so that the clutch/axle won't fall out

• A rack gear for creating Rack and Pinion mechanisms

• A Crown gear for transfering rotation around corners

• Cams for using servos and motors to move lever arms and pistons

• A reel and cable/chain that can be a Winch (for torque or for speed)

• A Shaft Encoder that understands direction and counts up/down accordingly

• A Ratchet that can be used to apply torque in one direction, but slips almost without friction in the other

• A high bandwith hard-wired connection between Vextrollers or one controller and another computer/coprocessor

• An IR communication transceiver for high bandwidth comms with other Vextrollers or other computers/coprocessors

• An RF communication transceiver for high bandwidth comms woth other Vextrollers or other computers/coprocessors

• Individual and grouped LEDs of multiple colors that can be set on/off by using serial I/O to send command "bits"/"words"

• Audio outputs

• A turntable that can support substantial weight

• A tailgate that can be attached at the end of a chute and raised/lowered by a servo

• A swivel joint made from a captive ball pierced by a rod/axle

I'm sure more ideas will come to me shortly....
