PF/9V update

Ni kanske kommer ihåg projektet med den laddbara 9V-motorn som skulle laddas genom spåren? Jag fick ett högst intressant mejl. Det verkar som han börjar ro projektet i land. Jättekul om nån kunde prova med ett standard lego batteri!

Hello again,
I just wanted to give you a quick update on my project. Here is the link to some
pictures:

First, I discovered that when the IR receiver is plugged into my 9v motor modified
with a pf cable, the IR receiver will be powered with electricity from the track
and the speed of the motor is controlled the IR remote. So you can now control
up to 8 trains all on a 9v system without investing on batteries. I made another
custom battery pack. It has all the functions of the Lego battery but it’s only
about half the size. It has a micro chip in it to keep it from over charging/discharging
and it also has short circuit protection. Also since there is an available port
on the IR receiver you can plug in a pf motor to drive that emerald night and
still get power from the tracks. Now when the system is all hooked up just plug
the 9v regulator to the tracks and turn the knob to full. Turning it the wrong
way will make the green light turn dim (sort circuit) This will not harm any
part of the system, just simply turn the knob in the other direction and the
battery will start charging. When the train moves over plastic track the train
will use the stored power in the battery. Just be sure you don’t have a turnaround
in the track layout because if the train motor is turned in the opposite direction
and goes over the 9v track it will not charge. Once again, this will NOT damage
anything; it just simply won’t charge the battery.

My system with MY battery is working flawlessly. And the 9v motor with IR receiver
and no battery works flawlessly. Please note I have yet to test this with the
LEGO brand battery, so please don’t use it with this system until I have time
to test it.
