I've noticed that because the Emerald Night's two sets of driver wheels are locked together, the engine struggles to go around corners: the outer wheels have further to turn, so the wheels slip and the engine's movement becomes jerky. Would it be (...) (15 years ago, 19-Jan-10, to lugnet.trains, lugnet.technic, lugnet.robotics, FTX)

Hi all. I am currently working on a project (to be revealed in due course!) and I've come across something of a stumbling block. I have a tray that is constrained to move in one dimension, and a series of short liftarms under the tray, all rotating (...) (15 years ago, 19-Jan-10, to lugnet.technic)

(...) (URL) a bit early for Mindstorms. I've only got a passing familiarity with the 4.5v system, but I believe that any parts that feature that type of 3-prong socket are designed for 4.5v power. All Mindstorms parts use either the 2x2x2/3 electric (...) (15 years ago, 19-Jan-10, to lugnet.technic)

Hi, I've got a black 3x2 block in my large mixed box of Technic, but I'm not sure what it does! The block has a power cable socket in the top, and a smooth axle hole through it, as well as a smaller hole on one side. I've looked through the various (...) (15 years ago, 18-Jan-10, to lugnet.technic)

(URL) Hi folks Last fall we had the swine flu outbreak - it spread here too, of course, and I fell ill too. While my symptoms remained vague, I was in bed for a week. And one week in bed tends to be kind of boring. So I took my brick boxes onto a (...) (15 years ago, 17-Jan-10, to lugnet.technic, lugnet.cad, FTX)

(...) A corollary to this (that I discovered yesterday - apologies if this is already well known) is that you can use a bushing to lock a driving ring to the axle - the same notches that allow the bushing to fit between four studs will act as the (...)

(...) Hi Ari, I'd love to build it. No lack of necessary parts here. Could you post (or send me) a copy of the LDraw file you took that screenshot from? Never mind if it's incomplete. It's just easier to build if I can see it from different angles. (...) (15 years ago, 7-Jan-10, to lugnet.technic, FTX)

Hi, here is an idea to build a good old fashioned twin stick truck transmission. I don't have enough synchro parts so I can't build this myself. Is there any volunteers to build and test it? :) (URL) Schematics> (URL) Twin Stick 5x4> More accurate (...) (15 years ago, 7-Jan-10, to lugnet.technic, FTX)
