It’s only those Sharp sensors which didn’t work for me… ok, and maybe the RFID readers are useless when the tag is on an engine as the magnetic fields kill it… (idea just popped up, insulate from engine/motor with some form of foil shielding…)

But such is life, I installed 10 LDRs last night and then ran out of time… retrofitting LDRs into the track base is a royal bastard, but the ones I have my hands on are much nicer than the standard orange ones. Keep an eye out for them!
