  1. Do you mean updating it each year? Yes, I've been doing that since 2017 (though I hadn't shared it yet), and I plan to keep doing it for the foreseeable future.
  2. I took apart my 42130 BMW yesterday, and got a few pictures to share: First is the large front shocks taken apart, for any curious about what that looks like: Next are two different ideas for using the disc brakes as rims. This first one is the Defender's (actually the old 8880 version, but it doesn't matter) tire on the non-Defender rim as a simple wheel cover for a strange futuristic look: The second is the Porsche/Bugatti/Lamborghini tire mounted on two discs, spaced two studs apart. They're not quite as big as they should be, but they hold the tire pretty nicely and look good. You'll give up the offset, though, so it's not a great idea.
  3. Hmm, my impression had been that this contest was intended to be for really small models, of only a couple hundred pieces or so. My opinion would be that a contest of really small stuff doesn't need a theme, but by the time we reach Corvette scale the entries will be too diverse to compare with each other effectively without some kind of theme. I think my preference would be for smaller stuff, just because it's an area I've never really explored, but I don't feel strongly about it.
  4. Ok, thanks for the thorough answer! I hope someone does a full on comparison video at some point, especially to compare torque outputs.
  5. Can you direct me to any info regarding the difference in power between CADA and Lego buggy motors?
  6. So, as you may know, I’ve built a couple mechanical calculators before, my Technivac I and Technivac II. I’m pleased to have completed those, but I recently came up with an idea that should make even state-of-the-art mechanical calculators like those look obsolete: namely, electrical calculators!!! Electronics would allow me to make the calculator far more compact, give me far superior reliability, and even allow me to add the elusive (though arguably irrelevant) multiplication and division operators. Naturally, I jumped into the powerful and innovative Lego Powered UP app as the obvious choice to attempt such a calculator. I had a few difficulties along the way, but no great breakthrough is without them. And a breakthrough it was! After only a few hours of labor, I had successfully created a completely electrical calculator controlled from my phone, which didn’t even require a single Lego brick (they’re overpriced anyways). Beyond that, as projected, the reliability was flawless, allowing me to add, subtract, multiply, and divide single-digit numbers with ease. I think this idea has enormous implications for the world that go far beyond being a simple Lego MOC! People everywhere will be able to trade in their mechanical calculators for a simple, pocket-sized device, freeing up valuable space in their houses that can now be filled with Furbys, or whatever the latest fad is these days! Beyond that, there will no longer be glaring mistakes in complex calculations, which should allow engineers to build bridges that will last longer than a week. My patent is still pending, but before I reveal this breakthrough to the public, I wanted to make it available to the community here on Eurobricks, free of charge! All you have to do to add this digital revolution to your pocket is download the Powered UP app (if you don’t already have it) and then copy the code blocks and widgets from the images provided here. Enjoy! Here’s a video, where you can see this marvel in action:
  7. Well, in a way yes. I did actually make what I said I made; the joke was more in why someone wouldmake it.
  8. Thank you! I agree that the ability to build this MOC without physical bricks at all is its key feature. Here are my previous two mechanical calculators, should one have archaic preferences in calculation technology: I'd have to learn how one of those works first... Thanks! If I had a tablet I could definitely make use of a larger user interface, but alas my phone is too small. It's also annoying how the only dials available take up a 2x2 space on the screen. A 1x1 one would be really handy! -------------------------- So, in case I didn't make the tongue-in-cheek nature of this post clear enough, this was my idea of an April Fools joke--A MOC that isn't really Lego in any meaningful way. In case you're wondering, I have actually been working on a third take on my Mechanical Calculator, and finished it a few days ago. It's still not as precise as I'd like, but I think it's nonetheless my best one yet. Once I get some more free time, I'll get around to posting it on here, so stay tuned for that.
  9. Nice job! I've never seen the rear suspension angled like that. Is there any advantage to that when the wheels aren't being steered?
  10. Again, nice and clean! One thing that could be worth trying is having two HOG knobs; one on the back, and one on the top. The top one would be used with a trailer attached, since there would then be enough weight on the rear for it to work, while the bottom would be used when there is no trailer, because there is then access to it.
  11. It might not be too bad with a backpack, but it still seems annoyingly complicated!
  12. I'd love to see any solutions people come up with for an onboard air compressor, but I can't help you there. I would imagine that by carefully operating the lever on a pneumatic valve, you could perhaps slow down the airflow enough even with a fixed-speed compressor, but I don't know for sure.
  13. It's cool to see in those different colors, but if I'm not mistaken those wheel covers don't exist in black.
  14. Though because the upper pivot is so far up, it is a smaller effect than it would be if it were lower down.
  15. I like it! It's a much more interesting suspension than we usually see, and looks pretty solid.
  16. Maybe this isn't helpful, but even when I bought a brand new one direct from Lego, it did have noticeable bend. It's not an issue in a model because of how easy it is to straighten under constraint, but maybe it's just normal for these parts.
  17. Very nice job and presentation! A trailer like this could easily become an afterthought, but you put a lot of thought and engineering into adding functions and giving them good execution.
  18. One suggestion for the front suspension would be to go to a MacPherson strut setup, using a spring taken from a small shock absorber on the steering pivot. This wouldn't be as realistic for this car, and could have trouble fitting under the hood, but would eliminate the need for any upper wishbone. I guess you could even just use a vertical axle for the strut to locate the axle, and then use a rubber band somewhere else for the actual springing.
  19. Nice job finding that! I'll have to pick up one of those in case I ever build a helicopter. It looks super convenient, and I wonder if it'll be used in the official helicopter rumored for this summer!
  20. Very nice! I like seeing complex mechanisms like this one. What is the black ball part you're using in the middle of the swashplate?
  21. Yesterday I got around to thinking about converting the 3+N transmission to a 4-speed, and came up with a solution I'm pretty happy with. It has an unfortunately small range of speeds, but they are still distinct and shift in order. Interestingly, the setup is dependent on the new non-beveled 12T gear to run a chain, although since I don't have one yet, I'm using a 3D-printed stand-in. Here's some pictures of the drivetrain model on its own, giving a good view of the modified gearing: So, the orange loop drawn on the bottom represents the chain, with drives its 16T gear, and then everything along the green line, causing the 20T and 16T clutch gears on opposite ends to rotate at different speeds. The axles the driving rings are kept running at slightly different speeds thanks to the chain drive with the orange line on it. At the top, under the red circle, is the new 12T gear, and at the bottom, in the purple circle, is a 12T gear. The upper driving ring's axle then continues through the blue drivetrain to run the engine. I forgot to take decent pictures of this before putting the bike back together, but the white 2L beam that is used to limit the shifting has to be rotated by 90 degrees in a specific direction relative to the wave selector to make sure that it shifts in the right order. Anyways, I think having a four-speed sounds a lot more impressive than a mere three-speed, so while there isn't really a functional advantage here, I'm happy to have the upgrade.
  22. There've been a bunch of times I've had just a little idea I wanted to post on here, without making a new thread for it. I've put them in different generic threads in the past, but I figured it might make sense just to make a personal thread to share stuff of this sort. Anyways, the first thing I want to share is this ten-sided "Geneva Mechanism" I came up with today. It's using a 10T splat gear with a pretty standard mechanism for rotating it intermittently, as in a stepper. However, rather than having a spring-loaded part pressing against the teeth of the gear as in a stepper, I've got a an axle that locks the teeth of the gear when it isn't being engaged. The same axle that runs the beam that steps the teeth is also hooked up to a wave selector, so that when it approaches the position in which it will have to move the teeth of the gear, the bump on the selector moves a linkage that briefly unlocks the gear, and then automatically locks it again after the motion is done. It's working well in one direction right now, as seen in the video, but it's not working the other way. I think this is because of the sideways force the wave selector exerts on the black beam, but I'm pretty confident it could be fixed with a more thoroughly engineered solution than this proof of concept.
  23. That probably is a factor, but I think the main thing is how the selector pushes the beam sideways. This sideways motion ends up pulling the axle back a bit before the beam has even popped up on the selector's bump, and I think it's this preselection that makes the one side work better than the other. Like I commented, though, I've got a totally different design that works quite a bit better, so I probably won't develop this design any further at present.
  24. And, I already came up with a design I like better... I should probably hold off on posting stuff like this until I refine it. Because of that principle, I'll wait on showing my new design until I decide if it's final or not.
