Ok, right off the top I need to say, I am not a fan of the Twiddler. But, I am a fan of standards. I have often berated friends and colleagues for insisting on some particular non standards compliant app or another because it gives them one feature they can't live with out. So, in the interest of "put up or shut up" I have made a concerted effort to learn and use a twiddler.
While doing this I found I needed to make it fit my hand better. The strap was too far forward on my hand so it did not ballance well. Moving the upper attachment point back a bit improved the feel of the keybord dramatically. I also discoverd I wanted to put my thumb against something when not chording with it. I know Thad brings his thumb to the palm side of the twiddler so it is on top of the strap sometimes, but I do not find that comfortable, so I added a small thumb rest on the other side of the device.
Finally, I wanted to make the thing bigger, so it would fit my hand better. I have done this a number of ways, but lately I have simplifed this down to a piece of foam that is slotted for the strap to go through. This can be easily changed in shape and thickness so you can try different pads until you get it the way you like it.
If you try this with your Twiddler I would love to see a picture and hear how it works for you, or if it does not, what you like better.
So, without any more words, here are the pictures: 2007 Twiddler hack
For the sake of the historical record, here are some pictures of an earlier Twiddler modification I did that is not as easy as this hack: 2005 Twiddler hack
