Calling all EE's, robotics nuts, technic gurus, PF fanatics, and electronics
geniuses...
So by using the PF to 9V connector wire, I can run a PF motor using the 9V Train
regulator. This is all wonderful...until I try to put an IR receiver between
them. When I do that, it doesn't work. Can anyone explain why this doesn't
work? I still have 9V going from the controller (it's turned all the way up) to
the IR receiver and then the motor connected to the IR receiver. In theory...it
should work. So...EE's and other electronics gurus...what am I missing? Is
there a workaround?
For those wondering, I am in the process of motorizing all of my switches on my
layout using PF motors and IR receivers. However, I would like to run them all
off of one or two Train controllers to eliminate the 'battery issue'.
Thanks in advance for any help.

| (...) The receiver works on the outer most two contacts of the PF cable, and the "legacy 9v" run on the inner most two wires. Basically, outer wires for the power bus for controllers, and inner two wires for load items such as lights and batteries. (...) (16 years ago, 25-Feb-09, to lugnet.technic)

| (...) Hi Dave, What you're missing is that the IR Receiver requires a specific PF input.. if you ask me that was a small oversight on the part of LEGO as far as backwards compatibility is concerned, but there is a relatively easy workaround. You can (...) (16 years ago, 25-Feb-09, to lugnet.technic)

| (...) Sheer awesomeness! I knew I could count on your guys for the answer and the workaround. Though it's not ideal to have to use the battery box, it's nonetheless a great workaround. Maybe LEGO will release a V2.0 connector that allows us to (...) (16 years ago, 25-Feb-09, to lugnet.technic)
