Rotary Stick Turns too Easy- Fix?
tommyinajar:
Someone had some old parts in a box and asked if I wanted to buy it. Mostly junk, but It had some Ikari style rotarys in there that felt ok in 8 way but they rotated almost freely. I never really looked at one in depth. What would be the cause and is it worth the time and money to fix it? (If you can even find individual OE or repo parts)- Thanks-
PL1:
Are you sure those are LS-30 (mechanical rotary) sticks and not Loop-24 (optical rotary) sticks?
There's a wiki page here on how to service the rotary switch on an LS-30.

EDIT: I haven't transferred all the pictures from the old wiki yet. :embarassed:
The old wiki page here has all the pics.
EDIT2: Wiki pic transfer done. :woot

Are the green handle ones the optical ones or did the LS-30 use both the yellow and green ? It's been a long time since I played or even looked at a rotary control- Thanks!

Yes, the green tops are the Loop-24 optical joys.
The LS-30 are the yellow tops & are rotary joys.
Second pic is the Loop-24 bottom open.

IIRC, Data East also made optical rotary sticks with barrel-shaped yellow handles and the octagonal yellow and green handles are interchangeable.
The best way to be sure what kind of rotary stick you have is to look at the number of pins in the rotary circuit.
Opticals will have 4 pins -- power, ground, and 2 data lines.
Mechanicals will have 13 pins -- 12 directions and ground.
The reason for counting pins is that rotary encoders like the GP Wiz40 and KADE combine the 12 directions into 3 groups of 4 plus a ground = 4 wires.
You connect every third directional connection together -- 1(1), 2(2), 3(3), 4(1), 5(2), 6(3), 7(1), 8(2), 9(3), 10(1), 11(2), 12(3) + ground.
This only uses three inputs + ground, and the encoder sends the output when you change from one input to another.
Input 1->2, 2->3, or 3->1 = right turn.
Input 3->2, 2->1, or 1->3 = left turn.

P.S. Great pics, Tron84.
Mind if I use those two for the wiki? (assuming they are your pics ;D)
If they're not yours, do you remember where you got them?
