    It depends on what you plan to do with them. For me, I prefer the 2 port train hub since my main use for them is running trains at our club's train show events. I use rechargeable NiMH batteries. They last an hour or two depending on the size and weight of the train. It is not hard to swap in a set of recharged batteries and recharge the depleted ones if you designed your MOCs for easy battery box access. Also the PU remote works with it so I don't have to use the Powered UP app on my tablet.

    Crappy BASIC style? I taught myself to program in BASIC. My code may read like a bad romance novel but they seem to work out in the end. Older school would be 1488 and 1489 level converters for RS232. I may have to build a serial IR tower one day when my LUG can meet again. One of my members has a SCOUT for me. Hopefully it won't be too hard to fix and get working. Are you writing your own serial communication routines for the ZX81?

    Nice build. I remember the ZX81. Do your cassette tapes still work? I may still have a Z80 processor somewhere. I was thinking the thread would be more like the Technic Pub where it is not too LEGO-centric and more on the off-topic side of shifting bits or shooting the breeze. Back in the days, I wrote some assembler to control fluid flow with an 8088 processor. I never did like the Intel segmented memory addressing. Coming from the MOS 6502 and Motorola 68000, the Intel drove me nuts. Making ASCII art on a IBM System/34's 5211 band printer was more entertaining.

    PV Productions sells Powered UP extension cables for 24.95 euros each. The PU connectors are not too hard to draw up in CAD and then 3D print them yourself.

    Michael posted that himself in this thread: https://www.eurobricks.com/forum/index.php?/forums/topic/183202-a-review-of-the-first-elements-from-the-fx-track-system/&do=findComment&comment=3357504

    Congrats.
  7. dr_spock
    That's great. Is that Apple IIc, Lisa, and OneScanner?
  8. dr_spock
    I asked Santa for better documentation and physical controllers. Other stuff I can build my own if required.

    I think the hardest set could be the 42114 Volvo hauler based on the number of help request threads on this forum.

    It is the white block with the 2 hubs. The order you link the hubs is important as you have to tell that white block which hub number is doing what. Here is an example of the input of color sensor on hub #1 port B controlling the output to motors on hub #2 port A and B.

    I had lucky experience pulling a portable outhouse car around on 2927 wheels at shows. It is not very free rolling but it never derailed. I think axle hole or something similar may be needed if the wheel is to be powered.

    Great job on the Amfleet II and Superliner II cars. How are the custom truck frames mounted?

    I suppose self-control or self-discipline. At some point overtorquing a screw or bolt will snap it.

    We can start a thread in the Mindstorms & Robotics forum. What should we call it? The Mindful Pub? Welcome aboard. Where in Canada are you? I went the DIY route. It is kind of fun to learn to design and make my own adapters with some old CAT3 cable wires and a few cents of 3D printer filament.. I think I stocked up enough PF motors to keep my GBCs going for a while before having to resort to PU motors as replacements. I used to do that too. The touch-typing class on manual typewriters I took in school was really useful for that.

    It probably wouldn't be too hard to bolt some Technic liftarms to an existing Traxxas chassis for mounting a Technic built body.

    1. Do you get in the ZONE while making MOCs? No. 2. What is the average DURATION of your MOC sessions? No idea, never really tracked the time. 3. Do you keep more than one MOC in progress at all times? Not usually. 4. Do you have MOCs that you like but just don't feel like finishing - you know how much work is LEFT to do? No. 5. Leonardo said Art is never finished only abandoned. Do you see it apply to MOCs? No. 6. Do you get anxious if you don't finish a MOC on time? No, it's a hobby to de-stress. 7. Original MOCs vs C-models? Both. I usually tweak sets to my personal liking. 8. How much time do you keep them for display later? Without modifying ANYTHING on them... At least for the entire LUG event season. 9. How is your SO dealing with your MOC spirit? All LEGO® must stay inside the designated area. 10. How much GB of data /photos, videos, schematics, renders, PDFs/ do you gather after each MOC? Probably less than a GB. 11. Do you delete your WIP footages once the thing is done? No.

    Those axles, pins, gears, etc. are also used more frequently in non-Technic sets targeted at younger builders. For example: LEGO® Friends Party Boat for age 7+ has a moving dance floor using Technic axles, connectors and bevel gears.

    You might have to make a custom cable or take apart and wire the battery boxes together. The PF extension cables and other components don't seem to permit connecting more than one power source.
  19. dr_spock
    Yes, you should be able to run PF motors off the RCX using the PF extension cables.

    Thank you, Tcm0 and Toastie.
  21. dr_spock
    Not really, some people have multiple accounts.
  22. dr_spock
    You could use a label maker like a Brother PTouch to print a label of letters to stick on your moc.
  23. dr_spock
    The poll appears to be limited to those with Google accounts.
  24. dr_spock
    Is there a way to emulate the serial or USB IR tower using a microcontroller + IR LED?
  25. dr_spock
    Because there isn't really much market demand for them? They do require more effort and skill to get working.
