Thanks for sharing although the video cut off at the good part and I don't see any of the pictures. I am assuming you have 3 volts of battery in a trailing car???
Yes, I am using CR123A, it makes thing much more easier. I tried to use 3.7V but then, I need to calculate a resistor or better a variable resistor. I found that it is very interesting but I will not have time to do it. Other option is button batteries in parallel but then there are 2 problems, a) short battery life; torque tuned consume 1.3-1.7A per hour, so a 230mah even in parallel will only last for 30 minutes. b) choking & swallowing hazard, I don't want any kid open the train (you never know how they did it) and eat the button batteries!
