    I think no, the max. current depends on the chips used, no matter where the 9V comes from, as you wrote. If they only alow 800mA i.E. it doesn't matter if your power supply could deliver 3A
  2. Lok24
    Yes, then, you just remove the two contacs from board.

    Additional: there is another problem. The axles are fixed in the frame, so only three of them have really contact to the track with metal wheels. (The lego 9V system picks up energy form the flanks of the track) One axle has to swing, then you always have for wheels with contact. I have a loco in 1:87 schale here, 105 gramm weight, and it runs like shown in the video.

    Sure, as your photos show. Nice work. You cold use other batteries like rechargeble Lipos and so on too.

    There is no "wait "in line 30, so line 31 is executed after the "run_angle" in line 30 is completed.

    That depends on the decoders and their technique. Good ones have UPS and receive the signal without contact to the track via capacitance coupling. Have a look https://www.lenz-elektronik.de/src/media/USP-HD-1280.mp4 And the engine is really small....

    The children I play with have an age af 2 an4 years and a Duplo train, they would never use the Duplo Loco without the tracks. Why should they do when tey are seven years old?
  8. Lok24
    Yes, this possible and very simple, but you loose a lot of facicilies of DCC. The DCC decoders start about 20,-- €, but you always need some central unit control to generate the signal on the track and handhelds if desired. The question is not what is possible but what you want to archieve. With your idea you get rid of the batteries but need the metal rails everywhere.

    Hi @DarioD I mean both, the real locos have complex lightnig patterns, and DCC decoders can (and do) reflect them all, and you have have a half a dozen switches (per model) to control that all. And it is not very usual to control several locos at the same time, normally you set up one loco (choose address, all properties are stored so that they easily can be acces on you handheld) make all preparations (Panto up, closing doors, setting lights, check brakes, whistle) , and then start it, while runnig you can start next train. I have been on many events where you have one person and one handheld per loco ! Absolutely! My approach: Value are always 0-100, if DC then motor.dc = val, if motor then motor.run=val*100, this is what you use too. But you can ask the port what type of motor ist attached and than use the best command for it. You find exmaples if you serch fot classPUPDevice(port) You can see that IDs 1+2 are dc, all other can use run. So just ask for the id, if < 3 then .dc, else use run. And there is a huge difference: the run command provides load contol, which makes it possible to drive really slow and constant, see my videos.

    With DCC you have to use special receivers in each loco and the metal rails, which is very useful, but expensive.

    And what about missing tracks?
  12. Lok24
    Hi @DarioD, I see, thats why I asked for the explanation of your Idea. And I understood that you wanted to establish a " "real" automatic lighting (forw/backw.)" I interpreted "real" as "realistic". All locomotives have lights that you can seperately turn on or off, since decades. Manually, because lightning depends of the actual situation the loco is in. Do the two programs only differ in line 103, and why do recommend the one?
  13. Lok24
    Hi @DarioD As I understand the color of the lamps depends of the direction of the train and cannot be switched via RC. As an iprovement you should then mount the red lamps in the last waggon of the train, because it indicates "end of train", with waggons attached there is no red "rear" light in the loco. The loco should show the right rear white lamp when working, if showing situation after 1947. And also be aware that a train with that loco could never move backwards. Perhaps while shunting , but i'm not sure. Or you use the buttons to turn on and off white and red seperately, for shunting purposes.
  14. Lok24
    Sounds interesting, is there a description or explanation of your idea?
  15. Lok24
    Great, thanks for your feedback!
  16. Lok24
    Don't know, but there are different classes for technic hub and Hub No 4 as well, If you don't acess the hub you don't need them
  17. Lok24
    A train without tracks? Really?
  18. Lok24
    According to the number and number of pieces it might be a giveaway....
  19. Lok24
    Yes, I do VB and VBA since 1995 writing complete applications including ASP, JT DB ans so on (before that I did some "Apps" in dBase 4 Clipper), but I' really very fond of Python, it's easy but allows complex programming. Why don't you start with a small project and pybricks? Its very well documented and has lots of example online.

    Hi, what's your intention with the 51515? That's the question. If you have a bunch of Powered up components, what would be different with the set? To me it seems that it's the programming languages, and I'm not a friend of scratch, because (as far as I know) you cannot minimize own blocks (subroutines), so you see all of your programm on one screen, always. And how do you want to control the Hub? Should it run independent from any outer control (Robot), with the Buttons only (very few, don't know if this is possible), or some gamepad or anything similar? And where should the "intelligence" be? In the hub? In some microcontroller? I don't see much advantage in the technic Large Hubs (except the the 6 Ports) I now used two methods with PU-Hubs: pybricks(python) and ESP32(C++), and both offer lots of potential. But that's only my point of view, of course. I could buy me a 51515, but I have no idea what to do with it, that I can't do with powered up With the EV3 I've be around on exhibtions to show children and parents how to build and program, but I will not do that with the 51515 because of the accu pack.

    They did not drop "mindstorms" the set 51515 is called LEGO® MINDSTORMS® Robot Inventor And yes, the hubs are included in the SPIKE sets, but you can buy them seperately, and as you can see in the link given from @Brickblock1, SPIKE is not even even mentioned there. It's just another technic hub, like the "technic Large Hub". In other words: the SPIKE PRIME does not contain a "SPIKE HUB" but a technic Hub. Have a look at the LEGO® Education SPIKE™ Prime Technical Specifications, there you find: Hardware name Technic™ Large Hub They all are summarized as "Powered up" no matter if the are contained in SPIK, RI,BOOST, technic Anyway: It's too much money, and its purpose is just to follow the lessons the SET is designed for.

    The same technic with four ports (without battery) , the technic hub, is sold for less then 20,--€ via Bricklink ......
  23. Lok24
    No, each of them it's a technic hub Of course names differ according to language, but normally they are called in the shop - technic Hub (used in the technic sets) - large technic Hub (SPIKE and RI) - small technic hub (the one announced here)
  24. Lok24
    Indeed, but more than 200 € for a 2 port Hub? Really?
  25. Lok24
    Hi @Cobalt Usagi, now found and Android device and tested your program, no disconnect at all. With motor running, with motor stopped, more than 5 minutes. Conclusion: the program is ok. But I could oly test with app Version 3.6.0, suppose you have 3.7.0?
