|
| (...) Very interested. I'm always on the lookout for new cam designs. The engine's very cool, although I can't quite visualize the motion. Thanks! Rick C. (18 years ago, 5-Feb-07, to lugnet.technic, FTX)

| | | | | New inline 4 cylinder Pneumatic Engine - No valves.
|
| Not quite the same old inline 4 underneath - this engine is only single acting, because to make it double acting would mean double the amount of t-pieces and cables, which is already a lot. anyway, no valves in this engine at all, just a mechanism (...)

| Here's an update on my parts experiments. I've added quite a few Technic parts: (URL) expansion link (URL) , based on a 1x3 thin liftarm, allows an axle or peg to slide in the 1x2 slotted hole. Very useful for steam engines: (URL) (It would go (...) (18 years ago, 2-Feb-07, to lugnet.parts.mod, lugnet.loc.uk, lugnet.announce.moc, lugnet.parts.custom, lugnet.technic)
| | | | | Re: R/C skid steer test
|
| (...) Nice idea. I made a similar prototype some time ago, which does not need a battery pack, but which can not have both tracks running in opposite direction. Some images here: (URL) Julien (18 years ago, 2-Feb-07, to lugnet.org.ca.rtltoronto, lugnet.technic)
| | | | | R/C skid steer test
|
| Well- I finally got around to testing the idea of a R/C tank. I built a little test rig just to see how it would work. The idea is an adder/subtractor drive, with the R/C "drive" output goes to a motor on the base input and the steering output tied (...)

Just to elaborate on my first post, this would be for display only - I'm not asking to take it home with me :-P If you have any other (...) (18 years ago, 1-Feb-07, to lugnet.build, lugnet.technic)

|
| (...) Come to think of it; if the difference in torque triggers a switch, that switch might as well trigger the off switch to the blade motor. The whole thing could be done 100% mechanically without the Mindstorms kit. Bummer. Oh well; that kit will (...) (18 years ago, 31-Jan-07, to lugnet.technic)
