My buddy on GH "Gator456" did a couple major Datahand improvements. One was adding a trackpoint from an IBM KPD8923, and the other was some sophisticated work using Teensy. Look up on GH, or on my "Everything Kinesis Advantage wiki, but here is the original wiki:http://geekhack.org/showwiki.php?title=Island:12212
I've looked at it before. I'm not quite convinced by the trackpoint placement, it's probably easy to reach but it seems that not having to move your fingers at all is kind of the point of a Datahand.
Yea, placement seems to be the only bummer. But for a guy that is using ice every day and laying on the floor to use his Datahand, if the trackpoint is working for him, it must not be as bad is it seems. The only other option I can think of is to have the Datahand on a pressure sensor to move the mouse, but then you are moving more than just your fingers.
I know this site as well, there really aren't all that many Datahand ressources it seems.
I really like his work, I'm jealous of his mechanical skills, I could never have built that chair mount. The footmouse idea seems totally ridiculous to me but apparently it works.
Ergo usually looks goofy. Definitely function over form *****I HAD TO EDIT THIS PALM PAD INFO...I HAD INCORRECT INFORMATION REGARDING SIZES AND THE GROOVY-GROOVE*****PALM PAD STUFF (for the more modern Datahands (Personal, Pro, Pro II)
- Sizes: Small and Large. But there is a smaller, undocumented palm pad that is Xtra Small.
- Attachment: Threaded insert now just a ball-shaped nubbin. (this change affected the Datahand unit itself as well).
- Design: Cross-hatched top, some have cross-hatched top with a deep groove around the perimeter of the cross-hatching
(not completely sure of this, maybe only the xtra-smalls have the groove, but minor detail and won't affect me molding replacements for people)
I am fixated on the palm pads only because it seems to me that the palm rests are important as part of the fit of the Datahand, and being close the the best size is of some importance, especially for RSI prone individuals. Datahand currently doesn't have large available, small being the only option at this point. Since purchasing used is the only option, it's rare someone has both sizes (I know for a time around 1999 Datahand would send Small and Large with a purchase) and it's a 50-50 shot if it comes with the best size for you.
<I don't really know where it's best to post this, I'm not trying to hijack your thread but I think it has value for some RSI inflicted persons. And since you are documenting tearing yours apart and modifying, it seems you may have an interest as well. Your photo thread may become a repository for some unique Datahand info on the web. Who knows, maybe you need a different size too? Using the pics below, which size do you have?>
Here are some pics Geoff sent me of the 3 sizes of palm rests, and the couple styles. I don't know when (serial #) they changed from the threaded insert to the locator nubbin. In one pic, there is an xtra-small with a scalloped underside and a groove. I had an xtra small, scalloped underside with the groove (circa 2009) and now have a large with no groove and a locator nubbin, so who knows? The groove doesn't matter but having a threaded insert or nubbin affects attachment. (The photos are labeled S-M-L... but that's not how it is....XS-S-L would be more correct).
