| I was inspired by Philo's pneumatic wheel and his ratio of 1 switch per piston. (URL) right, in that when I did my Inchworms they all used two switches per piston, and he cut it to one. I wondered how short I could make one of my inchworms and still (...) (17 years ago, 26-Dec-07, to lugnet.technic, lugnet.announce.moc)

|
| I was playing with pneumatic piston and switch linkages trying to improve on the geometries I've developed in the past. This lead to inchworm 4. (URL) 4 has two waves travel down its body like inchworm 3 (URL) big difference is the design of an (...) (17 years ago, 26-Dec-07, to lugnet.technic, lugnet.announce.moc)

| Real life has finally slowed down enough to have time to build. After showing off my robots at an elementary school in another town for three days, I got a huge burst of energy. My first creation was a new kind of pneumatic inchworm. It uses the (...) (17 years ago, 26-Dec-07, to lugnet.technic, lugnet.announce.moc)

| So I got the technic Motorized Bulldozer 8275 for Christmas. Haven't finished yet but I have started instruction book 2, so I can't say too much about it yet, but the new tracks look pretty sturdy. Anyone else get Technic for Chrimbo? (17 years ago, 25-Dec-07, to lugnet.technic)

| | | | | Re: Technicopedia
|
| (...) Good point, Philo. I did not choose very good wording here. What I meant was that, as a DC motor, there is no "hot" terminal and no "neutral" terminal. Therefore, you cannot hook it up wrong and damage it. I'll go back and see if I can clean (...) (17 years ago, 21-Dec-07, to lugnet.technic, FTX)

| Hi Blakbird, Little note about 4.5V motor: when you say "The motor is DC, so polarity is not important."... precisely since it is a DC motor, polarity IS important, rotation direction depends on it... Philo (17 years ago, 21-Dec-07, to lugnet.technic, FTX)
