About TK2241

  1. That's great! What about doing two magnets, maybe power and ground, and then pogo pins or something for the other connections? I'm planning on using a fixed decoupler on the track rather than building one into the engine. That way I can manage any number of cars. Another thought that would be cool would be some sort of clamp mechanism (similar to a real world train coupler) that could be powered to open and close. I'd have to do some sketches. But I really like the magnetic coupler here - great start!
  2. I like the 3D printed idea - I think smaller diameter magnets would probably work better. I really want to try getting 4 or 5 conductors into each car. I'll try my hand at something as well, and hopefully I'll have a 3D printer in a couple months ;-)
  3. I believe they're about the same size as the coupler magnets. But, I'll have to see if I can get them, and how much room there is to work with it. If they can be mounted on top of the existing magnet, that would be ideal. Yeah, but I want magnetic "self-locating" connectors so that I can automatically couple/decouple them. I think the magnetic USB connectors I found might work - I'm waiting to hear back from the company in China.
  4. Well, I just found these: https://www.alibaba.com/product-detail/Customized-powerful-magnetic-usb-5-pin_60628607437.html If I can buy less 5000 of them, that might just work And I would need to build some sort of swivel system like the magnetic car couplers. I was thinking maybe on top of the cars for ease of building. Definitely need to find some ideas on that... Not entirely sure yet. Basically I'll have five wires, two for power, and three for data. Leaving my options open for now. For my LEDs I've got one wire (three reall, vcc, ground, and one data) addressable strip, but I'm also looking in 1-wire devices.
  5. Hello all, I'm trying to find a way to create a power/data coupling between train cars that can be connected/disconnected like the car coupling magnets. Has anyone done anything like this? Background: This is so that I can supply power and control to LED lights (and maybe other devices) in the cars being pulled behind the engine, which will provide the power and control unit (Arduino based MCU) I've tried using a micro USB magnetic connector, but they are too bulky and don't flex easily enough for this. I'd love to find out if anyone has engineered anything similar. Thanks in advance! Arlo
  6. Hello everyone! Just saying hello here as my first post. This is an absolutely wonderful resource for all things Lego :) I'm an electronics and Lego enthusiast, filmmaker, and software architect by trade. See you 'round! Arlo
