This is my design for a thumbstick (joystick) for the Power Functions remote
control handset. I forgot about this until prompted, so here it is. It’s a
two-axis joystick that lets you move the stick up/down/left/right and operate
the two IR RC outputs of the selected channel. The up/down movement operates
the right (blue) channel #2, while left/right movement operates the left
(red) channel #1.

Okay, thanks for the recommendations everyone. But having done this, I now have
a new challenge (besides doing a better one of these, anyway).
Can you make a mechanical tank controller thumbstick? It should take in
up/down/left/right (+diagonal) motion like this one, but translate it into tank
drive commands, i.e. forward/back operations on the left and right controls
respectively.
Frankly, it’s got me stumped. It’s the diagonals that make it really hard.

OK, here is an attempted solution to the “new challenge”, i.e. translating
joystick movement to tank controls. It works, but it’s a little awkward to use
(pushing the joystick sideways requires quite a lot of force). I’m sure Jason
(or someone) can come up with a more elegant implementation...

I would really like a joystick with THREE degrees of freedom, controlling three
separate power functions switches - two controlled by moving back/forward and
left/right, and the third by ROTATING the joystick on its own axis. Any ideas
how to do this?

Yep, here is my version: http://flathen.net/tf/lego/pfremote/

See my concept design at http://flathen.net/tf/lego/pfremote/#3axis.
It is not complete since I don’t have enough parts, but you should get the idea.
I have also made an improved version since these photos were taken. I will try
to get it documented soon.

Whoah! These look amazing. Thanks also for the very clear pictures. I’ll be
trying these as soon as I get a moment. Also looking forward to seeing the
“improved version”...
