Which Spinner?
Brian74:
These are the two I was considering. I need to get a LED controller too. I have 2 ledwiz, maybe I will get the turbo twist. I just know it took forever to get stuff from ggg

I'm also in the process of deciding between a TurboTwist 2 vs Ultimarc Spintrak.
I'm planning to put ONE of these into an X Arcade Tankstik (the one with the trackball), likely located somewhere near the middle of the unit, thus drilling a new button-sized hole for either of these. I have it on order so I don't know what the internal clearance looks like, but others have added spinners w/o issue.
Is the Spintrak USB 2 interface a significant advantage over TurboTwist 2? Both are 1200 transitions/rotation.
I presume the knobs are universally compatible? The larger tokentop knob at groovygamegear allows you to forego a counterweight since it's heavier (http://groovygamegear.com/webstore/index.php?main_page=product_info&cPath=86&products_id=280)
I'm thinking of these options:
1. TT2 w/ USB interface + larger token-insert knob, no counterweight
2. Spintrak w/ USB 2 interface + larger token-insert know, no counterweight
Aside from buying from 2vendors thus a bit more shipping, any other thoughts?

+1 on TT2.
Consider getting the 7" steering wheel, too.

Without attempting to start any kind of war between the manufactures of these products, I wanted to throw my .02 in on the USB 1.1/USB 2.0 part of the discussion. I am no USB or electronics expert by any means, so take this with a grain of salt. And I welcome anyone who knows better to correct me. As I personally have wondered this in the past, and would like to know if there is a real-world difference here. Or if I'm mistaken in anyway of my thought process.
USB 2 has higher bandwith and lower latency than USB 1.1. In the case of a mouse/spinner, I highly doubt it's transmitting more than 12Mbit/sec of data limit of full bandwith 1.1. And I doubt the OS would ever poll the mouse faster than USB 1.1.
I'd be surprised if a spinner/mouse even transmits more than the 1.5Mbit of the low bandwith mode of 1.1. Granted, there is overhead in USB that eats into each packet, but I still doubt a mouse device would exceed it. Additionally, I believe the 2.0 specs don't require the HW mfg to support the full 480Mbit/s. Meaning if the device won't be using "High Speed" mode, it can still be compliant with 2.0 specs but only support "Low/Full Speed".
And while USB 2.0 does have a faster latency, (like 950ns for 2.0 vs 1ms for USB 1.1), I don't think the OS would even notice. But by default (for windows at least), the OS only polls the mouse every 125Hz (8ms) anyway. You can increase it, but I doubt you would get any benefit of increasing the polling rate to 1000Hz (1ms).
And as a full disclaimer, I went with the TT2 myself. Because I happened to place my first major order of supplies with Randy, and I felt they were comparable.

There is no real world, or any other difference when playing games. According to the numbers, based on the default 8ms poll rate (which can be increased with some OS tweaks, but won't provide a benefit) you would have to generate 125 (samples per second) x 127 (the max difference per each sample)= 15625 "ticks" on the encoder per second, before it was even noticed. This comes out to over 12 full revolutions on the TT2 per second. Considering that paddle games have less than a couple hundred positions on the screen, your player would be off the screen and in the next room in that second.
In other words, you are correct in your assessment. :)
If you've ever done a serial mouse hack, you know what happens when the limit is exceeded. Backspin, which is something you will never see on a current TurboTwist2, unless it is the fault of the game ROM you are playing. But the spinner hardware has nothing to do with that issue.
