  Question about gearing Power Functions-based trains
 
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)
 
  Some help or advice requested
 
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)
 
  Re: Please help me identify this brick!
 
(...) (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)

(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)

  Non-standard uses for parts
 
(...) 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 (...)

  Re: Volunteers to build and test twin stick transmission?
 
(...) 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)
