The hole could stop it from rolling if there isn't enough momentum. There are also molded ridges on the balls. Those could get caught in mechanisms with sharp edges? -

Cool, see you at BITS. -
9v motor dies after running for 2-3 mini
dr_spock replied to Chris Stransky's topic in LEGO Train Tech
Maybe connect a volt meter (or multimeter) to the output of the power pack and don't let it run above 9V? -
How do I control two PuP crocodiles simultaneously ?
dr_spock replied to Selander's topic in LEGO Train Tech
The PU remote can pair with more than one PU hub, if I recall. I guess one trick could be to fool the PU hub thinking that a PU train motor is attached. With the "train motor", one would get the variable speed control with the PU remote instead of the on-off. It can be done with an adapter going between motor and hub where the hub end of the adapter is wired to ID as a PU train motor. No programming or app are required. -
I believe the ESP32 has a built-in BASIC interpreter. It's basically for debugging if needed. There are also a number of BASIC interpreters for ESP32 on github. You can probably use Leguino to support Power UP hubs too.

The STL files are available. I suppose one can 3d print the enclosure. Then hack in a basic PWM board and a direction control SPDT switch for "dumb" speed control.

I think LEGO red is DD1A21 in hex. https://filamentcolors.xyz/colormatch/ Hatchbox ABS may be close. Finding an exact match can be hard. Shredding, melting, and extruding red LEGO bricks into ABS filament could give an exact match. :-)

3rd party or DIY may be the way to go for non-LEGO standard layout geometry. I see Chinese tracks go on bundle sales from time to time. To be sure, look at close up pictures of the product, if you don't see 3D print layer lines, then it is injected.

TrixBrix to start doing custom wheels and rods

The wheels on their product page look 3D printed. -
For a moment, I thought Mad Spamm Bomber was a new train MOC. Please use the Report feature under "..." (located at the upper right hand corner of each post) Select the "SPAM" from the drop down list. One of the available moderators or admin will take care of it.

I store my complete minifigs in plastic bags by type. There is a bag of pirates, a bag of minidolls, etc. The bags go and sit in a bin until needed for a MOC or vignette. When the MOC is disassembled, they go back into the baggies and bin. Minifigure parts and accessories are sorted into divided storage drawers like these. It makes it easier to find the pieces to add to the figs when building a MOC.

Having a patent doesn't mean they will make a motorcycle with it. But if someone else does, it's easy licensing money for Yamaha. I think they forgot the aroma aspect of the exhaust and the heat feeling. :-) -
I used to have all LEGO PF but lately I've been replacing bad motors with 3rd party. I noticed some of the 3rd party draw twice as much current than LEGO. Some seem to run a tad faster too. Before 3rd party, I had a batch of electric toy motors to rebuild burned out PF M motors. Pressing pinion gear on to replacement motor shaft is a pain. Buying 3rd party is much easier and cheaper than the new brass pinion gears and motors and labour.
