| | | Magnets, righto. How do I do that? I've spent most of today trying to put together a program for a pressure pad triggered setup, haven't had any sucess. Same with a light program. I don't have any idea how to use magnets. Do you have a program I (...) (20 years ago, 16-Dec-04, to lugnet.trains)

| | | | (...) You'll need more than a program, you'll need to make sensors of some sort, as sensors that detect magnets are not on offer from LEGO. Chris Phillips made some (reedswitch based, I think) sensors, and documented what he did. it requires some (...) (20 years ago, 16-Dec-04, to lugnet.trains, lugnet.robotics)

I'm not too crazy about modding Lego so I'll go with the pure version. (...) Right, I'd think you'd need a lead time of (...) (20 years ago, 16-Dec-04, to lugnet.trains)

His crossing gates are awesome, and the read switches that control them work very well. I just I (...) (20 years ago, 28-Dec-04, to lugnet.trains)
