Week TechVideo, 2011 #43 - 4-Speed Compact Gearbox

Most likely, some of you might have seen the 4-speed compact linear gearbox by Sariel

MisterFitzGibbon took up on this design and developed a very clever add-on, to change gears with one single motion. Every 90 degree turn, it sets the gearbox one speed up or down. 

Somehow this made me recall one other video where a Geneva mechanism was applied, to command a switch box and select one function..

That is pretty cool...

Sariel said...

Wow, that's clever! Even better than the hamster control system :) I think I'll be putting it to use in future.

Interesting this application of the Geneva Mechanism also. Thanks!

I wonder how the gear change could be driven by a remote controlled motor.
Any idea?
