Would anyone mind PMing me a link to these images? I don't have Instagram, so I can't see 'em that way, but I'm excited to see these sets!

I think there's some kind of built-in translation function on the website; otherwise Google can automatically translate that. At least, that's what I always did.

This here is a good website to check out for Stud.io files: https://fogeyman.tistory.com/

Wow, I finally looked up the sets that you're working with here, and was surprised at how ancient it was! I didn't realize there was any programmable stuff for the 4.5V system!

I kind of doubt that it would be able to be any cheaper. In a sense it ought to be, being quite a bit simpler than an electric one, but we're at a point where little electric motors are being mass produced, allowing them to be a lot cheaper than they would be otherwise. Because pneumatic motors would be so niche, they wouldn't be able to benefit from that scale. They sure would be cool, though!

Nice work! That does look a lot more natural than the original set, and fills a niche that Lego hasn't filled in a while. I appreciate that the extra parts have been kept to a minimum.

I believe The Unofficial Lego Technic Builder's Guide suggested that red was the weakest color, while yellow was the strongest. Most of the evidence for these different things is probably fairly anecdotal, though!

Might work! Unless you wanted to have a longer lever (with a higher pivot) to get more travel for the shifter

Cool! That ought to be possible one way or another

Yeah, it sure isn't. If it's anything like PF, getting a 9V transformer and just pinching the wires against the correct two contacts (Using old batteries as spacers, perhaps with some tape on their ends to avoid any electrical properties of theirs from having effect) could work, but you'd definitely want to do it right, and EV3 may be more picky about its voltage!

I'm pretty sure he's got add-on rechargeable battery packs in there replacing the AAs, and that the AC adapter is really just a charge port built in to the rechargeable pack.

Yeah, 24122 is only two studs wide, so it would be great there, but alas, it doesn't work that way. Unfortunate that 27940 is too wide for that. I wonder what other options there are. EDIT: Have you thought about using this part, 53585, with the through axle hole? It can have a lot of uses for this type of thing.

I made some more progress the other day, starting on the body of the "truck" that will be hauling this container. We've got an unload function based on a track section at the rear, which links with the container through two 2L pins, and unloads it using two coupled pullback motors. (I've decided to keep this model manual, and it's always fun to find a good use for trusty pullback motors) There's a few little wheels along the sides to help support the container as it slides off. (No, this doesn't make it a space car!), plus some rather Y-wing inspired booster engines alongside the container. I also built a gun that will be hidden under the hood. It's based on the 6-shooter piece, and will hopefully be aimable with a joystick and able-to-be-fired with a knob. I didn't grab a picture of it, so that'll have to wait until the next update!

Yeah, he's right. I've got one in my hands now, and it won't go into the pinhole. Perhaps you could use one of these instead, with one of the new friction stud-pins inside it:

Which can be added via an external hosting website, like Bricksafe.

4770 is long out of production, though, but I think it can be useful!

I'm pretty sure it could be done in theory, but there'd be some practical problems. For one, both of my mechanisms are already a little finicky because of the tight space I allowed for them, and a more complex mechanism really wouldn't help that. For another, I didn't want to take up too much of the interior space, (behind the spike) because the crew needs some room too! That's also why I didn't use motors.

I've made some solid progress lately, and have essentially finished the container part of the model! This is the container in its disguised form, but by turning a knob on the side, this spike will protrude, blowing out the rear doors! By turning another knob on the top, the four parts of the spike slide out in four different directions, tearing a hole in the hull of the enemy ship and allowing the container's crew to disembark into the ship. I've got a video of this action down at the bottom. These mechanisms were fairly hard to realize. I used two mirrored linkage setups to link the spikes into two pairs, and then controlled them with these two long 15L liftarms, which are driven by the square inner profile of a 28T turntable to allow them to function like a long extendable axle (Something similar and simpler could probably have been done with 16L axles, but I only have one real one that I can use in this contest, and I'd need two). Because of the square profile on the stationary part of the turntable, though, the turntables could not be rotated when the beams were slid back in for a stowed spike, but this wasn't a problem, since the spike doesn't have to expand until its extended all the way anyways. Also, I think this model will go quite nicely with my one Technic figure, who happens to be a police officer! Matched with a black helmet, I think he'll look pretty good! My next step will be to start building the "truck" that'll be carrying this container!

Welcome to Eurobricks! I'm pretty sure that should be fine. It might be hard to rotate that long red axle right now by grabbing the axle, but if you pull on the center lever (or the other one that isn't installed at this point in the build) you should have significantly more leverage to get it moving. That's a great set you're working on!

Sweet, thanks for the heads-up! The blue 12T/20T gears were both back in stock as well, along with some other cool stuff, so I'll finally get to try some of the new gears and pins out thanks to $20 in VIP points!

Ah, I see. That's annoying! Sometimes people just make torsion bar suspension by twisting axles, which is something you could try, but that can also be challenging to make hard, and would lose the quirky appeal of your solution!

If the pullback suspension is too soft, could you try preloading it by winding it up a bit before inserting the suspension arm?

Impressive performance for snow!

Nice work! I really like the unconventional suspension ideas. The links work nicely to simulate leaf springs; the Watt's linkage is cool to see, and the pullback torsion suspension is pretty awesome! Does it work well?

I was just looking through a new Lego catalog, and noticed this new wheelchair wheel part, part 80441, which looks to be a half stud thick with a pinhole. I wonder what uses it might have for Technic, being so small and skinny!
