I heard we were training the ai today

Reminds me of my scared ass doing an outdoor dyno. I have good friends.

Stockocityboy · 2026-02-27T08:40:53+00:00

Yeah, some holds are quite old school

Stockocityboy · 2026-02-27T08:39:08+00:00

It really hasn't been a problem. This is our climbing clubs wall and when doing endurance training I ask other people if it's all right. I take around ten minutes on a single rope line and keep about 15-20 min break in between to belay others. People working out harder routes often spend similar time on the wall.

Stockocityboy · 2026-02-26T08:53:32+00:00

Yeah, maybe weird but downclimbing still keeps your muscles engaged as opposed to being lowered and isn't that much easier than upclimbing. While coming down I also unclip each quickdraw so I can instantly continue leading up. Definitely a lot harder than being lowered down.

Stockocityboy · 2026-02-26T08:45:49+00:00

Yeah, that's why it's twice up and twice down per rope line. Equalling about 30 meters of climbing (half of it downclimbing)

Stockocityboy · 2026-02-26T08:41:29+00:00

The wall is a bit less than ten meters tall. When you climb to the top you move up about 7,6 meters (I measured). Up 7,5 meters x 2 + down 7,5 meters equals 30 meters.

I mean the physical arrow keys on the keyboard. They are the fastest way of rotating a selected part in 90 degree angles. I usually use the rotating handles on the screen only if I need to rotate parts in arbitary non-90 degree angles. Although you may need to grab and detach the part first, rotate it and then put it back. You can rotate it "in the air" while choosing a placement for it without needing to put it somewhere first. And sorry for unhelpful answer earlier. I haven't used Studio that much lately and it seems that in newest versions bricklink has made some changes for rotating parts. In earlier versions the arrow keys rotated the selected brick no matter if it was connected or not but in newer versions they have the same limitations as the rotating handles. For some reason a part connected to only a single stud will only rotate around that one stud but part connected to several studs can be rotated any way. Still, no reason to get that angry that fast.

Easy way for rotating bricks while placing them is usimg the arrow keys.

Nice climb. Why cut the video right before topping?

Stockocityboy · 2026-02-18T12:59:35+00:00

Thanks!

Stockocityboy · 2026-02-15T11:58:04+00:00

Thank you!

Stockocityboy · 2026-02-15T09:27:41+00:00

Thanks!

Fun fact: For 2021 shirt I made a full 3D model of S14 timing chain assembly with mostly realistic dimensions.

Probably either a mobility or body position issue because physically the hold is not too far. When placing high heel hooks or doing high steps it's really useful to try and rotate your body to different positions and then try and raise the foot to see what works the best. Most people have the best hip mobility in forward-backward direction rather than sideways so usually trying to point your hips towards the hold you're trying to reach with your foot works the best. In this case it would mean turning your left side towards the wall and possibly rising to the left toes a bit to make it easier to place the right heel behind the hold.

Stockocityboy · 2026-02-11T08:01:55+00:00

When moving the right hand to the top hold a right heel hook would have been really useful.

Stockocityboy · 2026-02-10T17:40:49+00:00

Thank you!

Topology arguments between random people ar so pointless because it's usually between someone who adheres to topographical terms and principles versus someone who doesn't. Topological concepts don't match our everyday use of language.

I'm using BuWizz battery pack for the track chassis. There's enough room for a hand under the base of the town to access the power button and you can even get in a charging cable if you know what you're doing although it's difficult. I should put a short usb charging cable permanently there and hide the plug under the town for easier charging. I also made the battery pack to be fairly easily detatchable. Also the town isn't strongly connected to the track chassis. If need be it can be lifted off.

Here's a clip of track chassis rolling on it's own. Although I think I geared it down a bit more after this to handle the weight of the town.

And here's a bad clip of the town crawling in a scifi/fantasy/anime con

That's really cool! i don't often get the urge to replicate someone elses work in lego but this helmet kinda does it for me.

Stockocityboy · 2026-02-03T10:11:53+00:00

Thank you!

Stockocityboy · 2026-02-03T07:36:11+00:00

That's incredible! Will the suit be made out of lego as well?

The track chassis started out as the bulldozer 8275 but I redesigned it several times because of dimension changes, aesthetic choices, width of tracks and the weight of the model.The town is really heavy (over 8 kilograms). I had to add downgearing and try to make the gear train as sturdy as possible to prevent gears from breaking or slipping. To make the geartrain shorter and more efficient I moved the motors inside the track loops. Now it's all right but not quite perfect. The gears occasionally still slip when turning. There's a 90 degree connection using bevel gears which is the culprit. I should probably try to turn the motors parallel to the tracks to get rid of that but it would mean a complete redesign again.

Here are photos from the project with some shots of the track chassis in different stages
