Ultimarc U360 Mod to add rotary function&Top-fire/LED
(1/21) > >>
Bender:
I was able to convert a U360 to a top fire and then the Idea hit me, why not try to make it rotary too.
I'll have to modify my top fire design too, because it's based on the shaft NOT spinning
but I think I have an idea for that

I saw this hack for a regular joystick
http://www.trimoor.com/rotary_joystick/index.htm

I was thinking I could do something similar by adding a rotary pot to the bottom of the shaft and attaching the magnet to the bottom of that.

also the shaft for the bat type stick is wider than the ball top one and would be easier to hollow out, but has a much larger thread on top. does anyone know if there are ball tops available to fit that thread?

any one know where to buy rotary pots/encoders?
like the one in this mouse

AndyWarne:
The bat-top shaft is the same diameter as the ball-top except the visible part.

Thats an unusual mouse, never seen one with that type of self-contained encoder before. Is it an old one?

Spacejack:
If that didn't work, maybe you could mark the magnet and point an encoder at it somehow, like on a sidelong post.  You'd have to cover up the LED in the ultrastick though.
Cornchip:
 Cool link Bender. Thanks.
