I built this several years ago but I'm just now getting around to posting about it online. I have a TON of Lego PBricks / Train Regulators / controllers that use a 9-12V~ transformer. I don't know about you all but AC adapters and transformers drive me up the wall, especially as a project demands more and more of them. I decided to find a somewhat beefy transformer and create an enclosure with power jacks for all my of Lego devices (I've done a similar thing in my garage for all of my DC devices such as routers, USB hubs, HDMI splitters etc.). Maybe it will inspire someone to build a similar project and simplify setting up at conventions or at home. Towards the end of the video I also give a tip for a much more simple solution for fewer devices and requires no soldering. If you know of any other Lego devices that used 9-12V~ transformers I'd be interested to find out (I think I got them all?). Also any constructive criticism on the technical aspects are welcome, I've already thought of a few critiques Something I just thought of while watching a David Koudys video on YouTube, something like this could be used to keep firmware / programs on RCX bricks instead of leaving batteries in for whenever the "next time" you'll use them will be Although I've been uploading videos to YouTube for well over 10 years I am still very much a newbie. Still working on lighting, sound, color correction etc. so any constructive criticism is most welcome

After much searching I finally found what I needed. I just needed the right block to send the right command. I don't think it was on the HiTechnic site but I did find it elsewhere. Maybe this will help someone in the future https://modernroboticsinc.com/download/hitechnic-power-functions-single-irlink-sensor-block-for-mindstorms-nxt-software/

I haven't been able to find how to send commands to a PF receiver like a train controller would using the HiTechnic IRLink. I need to send a one time command for power level 7 in either direction. I am using a PF servo motor to control the direction of a monorail. I can control the servo with the IRLink but it just returns to center after a second or so unless I loop the IR command. Since the IRLink will most likely be used to control many other IR devices I want to be able to send a single command for the 3 states. I'm including a short video illustrating my dilemma. For bonus point I'll also include a short video of my current work around which would tie up two motor outputs on one of my controllers. I typically use the official NXT-G for programming or NXC in some cases. I haven't used either language in about 4 years so I'm trying to get back up to speed. Any help is greatly appreciated!

Right? I've seen some third party narrow gauge train track with larger radius curves and straight tracks but It would be quite the challenge to power it in a 4 wide setup. I still might have to try at some point though

I Recently purchased 2 of the Lego High-Speed Train 40518 sets. My first thought was to get some narrow gauge straight track and use it as a display piece but ended up modifying it for use with the monorail system. It's not minifig scale by any means but I still like how it looks traveling around the city (WIP).

Necro-ing this thread since it's what I came across in my search for a solution. I'm using BS Backup on Windows 10 and it hangs on "getting list...". I've tried running as admin and compatibility modes. I've also sent an email to the author in the off chance of getting a response. I will update if I find a solution. Posting here to see if anyone has any ideas or other solutions.
