Okay, here's another cool thing about the Droid Development Kit -- it includes a bunch of the new three-way bevel gears. I call them "three-way" bevel gears because they're like two bevel gears back-to-back with a normal gear in the middle. The (...) (25 years ago, 1-Sep-99, to lugnet.robotics)

(...) Quite useful too - I used the 20t gear in my (very simple) calipers which are now on the web: (URL) Those 4-stud-long gear rack thingies have 10 teeth each, and I wanted to get close to one increment on the rotation sensor per stud of (...) (25 years ago, 1-Sep-99, to lugnet.robotics)

(...) (actual URL is (URL) ) (...) Those calipers are pretty cool. It seems to me though you could get more precision, since the slop on the gears is a lot less than half a stud. The rotation sensor presents very little friction torque, so I imagine (...) (25 years ago, 1-Sep-99, to lugnet.robotics)

The new gear sizes inspired me so much that I created a huge listing of all gear ratios that can be created with the gear sizes now available and put it up on my web site: (URL) case you're wondering, this is useful mainly for building clocks that (...) (25 years ago, 1-Sep-99, to lugnet.robotics)

(...) New gears... Excellent. Has anyone seen these gears in any other sets besides the Droid Kit? How about new technic service packs? Any listed in the newest Shop@home catalog? <ICS> -- Did you check the web site first?: (URL) (25 years ago, 6-Sep-99, to lugnet.robotics)

(...) I got mine in the 8448 super car. They provide some of the five forward speeds in the gearbox. That's a sweet gearbox too... Cheers, - Ben. ---...--- Ben Williamson benw@pobox.com (URL) you check the web site first?: (URL) (25 years ago, 6-Sep-99, to lugnet.robotics)

(...) That makes sense. With the two new sizes you end up with five different ratios that can be constructed with two gears at a 2-stud (16 millimeter) axle spacing: 8 <-> 24 1:3 ratio 12 <-> 20 1:1.4 ratio 16 <-> 16 1:1 ratio 20 <-> 12 1.4:1 ratio (...) (25 years ago, 7-Sep-99, to lugnet.robotics)
