 | | 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 (...)

| | | | | New modded parts
|
| 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 (...)

|
| (...) Don't everyone jump up at once! I'm just looking for something that looks nice and will at least roll. 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)
| | | | | Re: Mindstorms question
|
| (...) Thanks for the reply. If everything you say is true, I might use multiple white clutch gears on one axle, gear them to a differential and use the difference in torque to trigger a lever- which can activate the touch sensor. It sounds better to (...) (18 years ago, 31-Jan-07, to lugnet.technic)
| | | | | Request: 1/19 scale tank/heavy machinery for PDX
|
| Hi I've usually a lurker on lugnet, but as Brickfest PDX nears I figure its time to speak up. I'm hoping to bring a 14-wide model semi with lowboy in the Model Team style to this brickfest. I've been building it for almost a year, and should have it (...) (18 years ago, 31-Jan-07, to lugnet.build, lugnet.technic)
