I'm rocking the 3200dpi CST now.
.2 of a spin to cross 3760 pixels. Sounds about right.
Would anybody like to contribute to the Trackball Wiki by posting results?
Hahaha - competing TRACKBALL wikis. Talk about a subsegment of a market.
It's like two people on a desert island arguing all the time.
Just set the mouse sensitivity to 6/11 and roll the ball please.
3200 DPI ROCKS!!!
300 DPI doesn't.
If you're not going to help you can go away now.
Will you be this argumentative at work?
Technically you are not threadcrapping since this is not the Classifieds but you are definitely threadpooping.
Go away.
I move the Kensington trackball and it doesn't go very far.
I move the CST trackball and it goes a lot further.
I think it is a relevant and interesting thing to consider in Trackballs.
Now stop being a ****head.
That doesn't look like MY Kensington Expert.
Are you trolling me? Notice the good old Cypress chip. I see that USB Micontroller EVERYWHERE. Blue Cube. Nostromo. I think even Leopolds - or Pokers. Can't remember which.
Oh now that IS interesting. Hmm.... I wonder how this is working. I'm getting like 500dpi using my technique. Maybe the vendor fiddles with resolution?
In the end it really doesn't matter. It's the RELATIVE sensitivity that matters. For example comparing with the Logitech M570.
So how many spins does it take for your Expert to cross your screen at 1:1 SW settings?
I don't think you're going to do very well in your new job.
Terrible team player.
I'd report your trolling but I'm no snitch.
The DPI on the CH Gen1 and Gen2 trackballs are pretty so-so.
if anybody wants to help compile DPI/Sensitiivity/Whatchamacallit parameters please roll your ball following the instructions in the OP.
Let me know if you find out the DPI on the CH Trackball. I want to compare it to my measurements.
You're about as helpful to the Geekhack Community as a blackhead on Rebecca Black.
So far you told me the DPI is either 1000 or 800.
It's kinda confusing.
I get 460 dpi for the currently shipping Kensington Expert. Same method. Same Windows settings.
This is why the post title is what it is.
Yeah, 400 or so sounds/feels about right.
Now I have to figure out if that 300dpi for the Orbit is right. Seems like they would all share the same sensor and microcontroller.
After using the slimblade for a day, I think the twisting ball scroll works well for an average user but my hand get tired of twisting this ball again and again.You're doing it wrong, or I am an average user.
It's built in HW acceleration. If you go slow the test should be accurate.
I'll be updating the "All About Trackballs" wiki with acceleration technical details.

Deceleration doesn't make sense or else it would be too slow and would go against the normal operation of the sensor, an acceleration limit is more logical
In other words you can have a really low sensitivity if you move slowly but the second you flick it hard enough you can actuate the delta and move as fast as high sens.
The way mice and trackball sensors work is they automatically slow down based on the input provided and no this isn't dynamic DPI.
Post the number of revolutions it took, your horizontal screen resolution, and your OS.
(...) In essense this test is better described as "default sensitivity". Still in the end it's what get's reported to the OS that is what the user primarily sees.Default sensitivity is what you get when you kill all the proprietary software. And yes acceleration is a *****.
Maybe I should have chosen a more diplomatic thread title.
Still, from these preliminary numbers I'm not seeing why the MTOs and MTEs sell for $200 plus on Ebay.
Because there is more to trackballs than just DPI :)
Need mto numbahs!!!!
Well if dpi is the only problem with my trackman, the dpi has a major influence. This thing is completely unusable

Just kinda wanted to throw that in there
The CST has some but on a trackball it's quite handy.Probably just due to the high amount of acceleration Windows forces. The amount windows forces cuts down consistent twitch accuracy, I notice it just in moving around folders in explorer. On paper it sounds like an amazing implementation, but you do lose consistency.
Not sure why the mice guys always have such a fit about acceleration anyway. Sounds overblown as an issue since my MX518 is fine as a gaming mouse.

Using the Kensington Orbit without a scroll ring, it takes 1.5 spins to cross my screen at 1360*768 at 6/11 mouse sensitivity on Windows XP 64-bit. I never cared about DPI to be honest.
