| Would you please make the clickable images larger? They are only 384x288 pixels, which is pretty small. I want to see super-up-close detail, so give us some higher resolution photos, please! (20 years ago, 11-Aug-04, to lugnet.dear-lego) !

| (...) That's good to hear. Right after I made the original post on LUGNET I went to the LEGO website and filled in their feedback form, too. So LEGO's getting the comment from two places. (20 years ago, 12-Aug-04, to lugnet.dear-lego)

| | 4512 is great to modify
|
| I got a 4512 Cargo Train yesterday. It's my second train set, and I really like it. It derails on tight curves, though, but then you wouldn't expect a cargo train to be flying down the track anyway. I noticed while building the engine that it was (...)

| What's funny is the other day I was thinking of building a marble machine with LEGO. After reading about this contraption system, I got super-motivated and built myself a ball pump last night. I only spent a few hours on it, but I think I have it (...) (20 years ago, 20-Jan-05, to lugnet.robotics, FTX)

I might not even need tension in the chain at all; the tread links slide on the flat bottom part (...) (20 years ago, 21-Jan-05, to lugnet.robotics, FTX)

| | What should you do with a stuck motor?
|
| Last night I had a new-style 9V motor attached directly to a 40-tooth gear that was turning an 8-tooth gear. There was a fair amount of torque involved, and my motor stalled after a while. Now the thing won't turn unless I really force it. What (...) (19 years ago, 29-Jun-05, to lugnet.technic, lugnet.robotics, FTX)

| | Avoiding motor stalls
|
| I broke another 9V motor. See my (URL) post> for the first story. I'm building what amounts to a pitching machine for the Great Ball Contraption. In most TECHNIC building you're building a gear train to produce lots of power at the expense of speed. (...) (19 years ago, 9-Jul-05, to lugnet.technic, lugnet.robotics, FTX)

| I thought of something else. I'm testing this thing with an RCX, and could it be that as the batteries get weaker the motor loses power, which makes stalls even more dangerous? (19 years ago, 9-Jul-05, to lugnet.technic, FTX)

| Update: there are now two motors driving this thing. They each have an 8 tooth gear that turn a 40-tooth gear placed between them -- instant torque, but less output speed. I put another 40-tooth gear on the same axle as that one and connect that (...) (19 years ago, 18-Jul-05, to lugnet.technic, FTX)
