Open of my James OT-3

Hi this is a video to show the new James. I love the motor has NO solder, so I can easily swap to any motor I want!



Taking it apart!


Motor connect with no solder, easy swap!

Motor Swapped [Sorry the swap part out of camera and out focus, so I cut it off]
Motor swap. My 3 years old son is there as well.


James's gears




Opening the Chatting Cargo:


When i opened it, the yellow wire is disconnected. I have to solder it and now, when wheel turns every 6-8 times, it will speak out and no need to press the button.

Simple Battery MOD for CR123A [Get the part from a R/C toy's controller]




Draw back, CAD$5 per battery. I am going to use 14500 3.7v to test out.

Thanks for reading. Next Project, add a LED light to James front.

Another motor swap, this one is easy!

Hi Lee & son

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???

Am I the only one that does not see any pictures?

No. I can't either. Just too lazy to work on it, just copy the link and put up on a browser, then you will able to see it.

Please PM me if you know how to fix this problem anyone.

Yes, I did swap the motor to Torque Tune. I post in under MOD. Now I am working to install the LED in front of it. But I broke the switch, so, I need to find/buy another replacement. Next step will then be drill, and some soldering. I will post it once done. Last phrase will be the passage cargo. I will do what Tramp did, using SMD LED but it is hard to find here and I need to order those LED from Asia, won't come until end of July.

May be I am a new member, attachment option is not allowed or not show as in the youtube video. So, I use link.

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!
