Hey all, Well I’m at it again. This time I bring you something with more usability. As most of you reading this should know the Lego Company recently released 2 IR train sets. While the idea is great, the implementation left much to be desired. The (...)

(...) <SNIP> (...) Well, its persuaded me to go and get one to modify sometime :) (...) Seeing a the instructions are already here (in your post). I'd look at selling preassembled units rather than explaining how to further than you already have. (18 years ago, 31-Jul-06, to lugnet.trains, lugnet.parts.custom, lugnet.parts.mod)

(...) It's a nice modification, but I can't help thinking it'd be better and cheaper all round to just build an IR receiver circuit for this - there's very little of the original configuration left in your mod. One mod I would like to see (to save (...) (18 years ago, 31-Jul-06, to lugnet.trains, lugnet.parts.custom, lugnet.parts.mod, FTX)

(...) It would be a useful exercise for someone with electronics skills to (if possible) figure out the IR stuff and draw up a circuit diagram for the IR baseplate piece. (18 years ago, 1-Aug-06, to lugnet.trains, lugnet.parts.custom, lugnet.parts.mod)

(...) I’m still trying to figure all that out. If I make 20+ at a time it wouldn't be horrible but it's still a little time consuming.

(...) Actually, it would be easy enough for someone with electronics and microcontroller experience just to build a new receiver. You typically record the IR signals on a PC, figure out how they're coded, then program a microcontroller to decode (...)

(...) Actually a typical bridge rectifier will drop ~1.4 volts in the supply. That's alot! About a 16% drop in voltage, and a 29% drop in overall power at the top end. I'm not sure what effect this would have on the control circuitry. Mat (18 years ago, 27-Sep-06, to lugnet.trains, lugnet.parts.custom, lugnet.parts.mod, FTX)
