So there could be some "transmission" and 24 notches in Happ optical rotary does not really define its resolution.
There is no "transmission" in a Happ optical rotary. It is 1:1.
Anyway, we all understand how mechanical transmission works with larger and smaller gears/rollers/balls changing rotation ratio, but how does software "transmission" work, what about "multiplier" thing? Would it be possible then to have 25x multiplier built in optical board and get higher resolution than Arkanoid even if with only 24 notches encoder wheel?
How did you arrive at 96 counts, is that "at least"?
No, that is the maximum. You could get 24, 48 or 96, depending on the decoding scheme, from that encoder wheel.
I never disagreed about "tactile feedback", that's a part of personal preferences and out of the scope of what I wish to discuss. Only if you mean to suggest it can impact the score, only then it is worth discussion, but otherwise it's for everyone to figure out for themselves. Do you agree?
It certainly can impact the score. If you concede that detents are helpful, then you must also concede that the lack of them places a certain disadvantage on the player. How much will depend on the players themselves, but less effort concentrating on the control will almost always mean a better ability to concentrate on actually playing the game.
Have you actually tried playing any mechanical rotary games with optical rotary? I don't have any such problems as you describe. Do you think that's how it is to play Caliber .50 this joystick was made for and has 24 positions? Do you believe there would be twice as much "erroneous movement" than with Ikari Warriors, or half as much? If you can properly play Caliber .50 with it, then surely it would be even more suitable for those mechanical rotary games with half the precision, yes?
Yes, I have played these games, with both types of controls. If not, I would not be commenting. I've also played them with an up down spinner, where the fire button was mapped to the down switch. There are a number of ways to get the input the game expects, but there are always compromises without the actual control. A game with finer granularity in positioning will benefit from the optical approach, more so than one where fewer positions are used. This is simple to explain; The greater the distance between the points at which your movement of the control actually results in a change in the game, the more difficult it is to judge where that change occurs, or where in that zone you currently are.
Why did you say that? If you mean to imply I took that absurd position then please quote me as you seem to be misinterpreting something. I repeated several times and was very clear what my position is, please:
Oh, I have plenty of resolution on my optical rotary, playing Tempest or Arkanoid is much better than with a mouse, almost as good as with a spinner, I really enjoy it and I don't feel the playability is compromised at all
While you may not "feel the playability is compromised at all", it most certainly is with those titles. If you enjoy playing them with the additional hampering added by the control, that's fine. It's not for me to judge what makes folks happy. However, if you want to promote the notion that there is little difference, then that is just misleading to folks who may not have the experience to know otherwise. Those who do have that experience, are attempting to temper your enthusiasm for poor controls with some facts about the originals, in order to stem the flow of misinformation and to help prevent disappointment for folks who are looking for the most enjoyable ways to play the games.
- Resolution = Not sure if this is correct. Not sure if Randy is calculating the diameter of the wheel. However, so what. The game will never play well with a stick, even With the res.
The diameter of the encoder wheel has absolutely no bearing on the resolution or feel. You turn the center of the wheel (more specifically, the knob attached to it), and everything else follows that, regardless of the distance between it and the outside edge. Tempest used a 72 aperture encoder, decoded at 1x. A 24 aperture encoder, decoded at 4x, is actually higher resolution than required by the game. But you won't find any argument from me about the playability statement

could someone make a rubber sleeve like a kid's pencil gripper to go over the bat and give an octagon, grippy tactile surface? Seems like I saw somewhere that those were able to be prototyped fairly cheaply. Could somebody do a one off by putting on that Sculpey clay and molding it around a bat top? If it were me prototyping it I would make an octagon grip out of hardwood, demo the bat top plastic and glue it on more or less permanently as Xiao2 mentioned.
Honestly, I like the idea of milling the handle to have flats on it. A 3-Axis mill, or Shopsmith type machine, could do this pretty easily. Barring that, a short section (3/4 to 1" long) of soft silicone tubing, of the proper diameter and thickness, could be stretched over the knob to provide a more comfortable and less "slippy" grip.
One could also approach the problem by making a slip-on cover, held to the handle by nylon set screws.
