Thats the idea I had, though I thought using peizos would be a little expensive. The one I had had two incarnations; one with pot's and one with microswithes off an old mouse. On the first I have 2 small pots. They were a neat kind, with resestance speints in them, so they would turn back to 0 by themselves when the pull was lessened. The second was just 3 on-and-off microswitches, one for up, down, and enter. Most of my ideas work of the 'low cost' theme. But, it is quite a novel idea. I'd love to be able to operate my HUD just by guesturing. Perhaps use a few relays, then you could use a standard keyboard generator module. One more hand idea I'm in the middle of trying : A nifty Multi-glove-tester. It involves putting each probe of the meter on the first and second fingers. The really cool part it that the probe tips are retactable using the same idea as a ball-point pen. When you push on them , they retract and lock above the fingernails, and one more push, or pressing them against a tabletop or something will extend them again. The 'on' switch is a pad on the 3rd finger and the thumb. So, touch those two together, and touch the probes where you want and you have a one-handed meter. The only problem is where to mount the main display unit of the meter. -----== Posted via Deja News, The Leader in Internet Discussion ==----- http://www.dejanews.com/ Now offering spam-free web-based newsreading
