| | Power Functions train controller
|

I've been reading the Power Functions protocol specification. I'm thinking that the train controller is using: Single Output Mode Mode = Clear/Set/Toggle 0100 Increment PWM and 0101 Decrement PWM when you spin a knob. Possibly Single Output Mode (...)

(...) Agreed. 8479 while having 4 models has a one clear "main" model. 8485 in my mind, has two main models and one alternate model. But neither are universal sets. 8094 is a universal set, in my line of thinking. (16 years ago, 17-May-09, to lugnet.technic, FTX)

(...) Hi Eric, awesome update. It's no wonder that I only have three technic universal sets in my collection - and one of these was a gift, 8020. The other two are 8082, along with 8456, the fiber optic set from 1996, which I consider a universal (...) (16 years ago, 17-May-09, to lugnet.technic, FTX)

(...) He probably means two clutch gears in a single axle, meshing with two other gears which also share an axle. That way (in parallel) they should slip at twice the nominal torque. (16 years ago, 18-Apr-09, to lugnet.technic)

(...) That's not a bug- it's a feature. The point is to protect the motor from damage. That said, I bet if you used two clutch gears you'll get twice the allowable torque. I don't recommend it- but you could try it and see what you think. (16 years ago, 17-Apr-09, to lugnet.technic)

(...) With the PF and NXT motors, i perhaps agree with you. Of course, you can get any torque limit you want by gearing up and then back down, it's just more awkward. (16 years ago, 16-Apr-09, to lugnet.technic)

(...) I think it's a non-issue for the most part. The torque isn't really "over a range" - it's different for different clutch gears, but for any *single* clutch gear it's pretty constant. After all, if it has a point at which it starts slipping, it (...) (16 years ago, 16-Apr-09, to lugnet.technic)
