Technic tango

Just had alot of fun reading this, and thought I would share a tool I made for my grade 11 final project for making triangles that have whole number sides: Triangle tool on github

Im trying to make a very compact 6 cylinder ross yoke engine with a 9x15 stud footprint for use in my moc, and im wondering if anyone could help me with a linkage for my valves. If you are familiar with the engine, im trying to use the centeral stabilizing rod to facilitate movement of the valves. Here is a detailed video of the situation on youtube: Ross yoke video

Can i do the droideka set 8002? It has the technic logo on the box but i was advised to ask first before undertaking such a project. It has super cool functions and i really wanna try compacting it, perhaps looking at the bakugan mechanism to do the iconic roll and pop up @Jim

Kinda neat how the rotary catch holds the ball joint knob back and forth, pushing the forks back and forth and in turn moving the driving rings. Seems much closer to a real gearbox now.

I built this project as an exe so if anyone wants to try it out they can: https://github.com/mcneds/Trigen/releases

This tool Includes all possible unique orientations of right triangles, and a portion of scalene ones that arent necessarily right angle triangles by subtracting and verifying it is scalene. All sides are whole numbers. I didnt add a button to change the range from the current 1-10 but its in the first couple lines of code so you could change it yourself if you wanted to.

whats the best pneumatic tubing for lego swtichless lpe? every "silicone" tubing ive tried hasnt been soft enough that going switchless is more efficient than switches

Showcase

Used it with 2 buggy motors and 2 buwizz with 15:1 gear ratio around my rock garden with no issues until the buwizz died

Well if you take a look at the original u joint, it isnt supported either because it tends to be strongly supported on its other side when you use it. The only weak part is the drawback most custom hubs have: the actual connection point isnt restrained to slide off like a normal hub. Heres how im using the hub, the construction is exceedingly sturdy: So because its supported at the steering pivot, it doesnt need anything there cuz i left it to who is using it to design that part to their needs.

i finally figured out how to embed pictures actually in the post so it shows them yayy

I made this for a project where I accidentally built the axles 4 studs too wide on each side so with this I'm halfway there if i use this hub and the landrover rims. here's the link to the video

Possibly micromotor from cada? _____________________________ different post due to merging Im making a bogey with self contained suspension and steering, but due to lego axle torsion there is alot of play. I attempted to add sort of a steering lock here with the pneumatics but that would make the suspension not work and it would introduce bump steer. Any thoughts on how to add a lock here?

Ive tried a few times and it never really worked for me. I was also thinking that since im printing i can use fasteners that are inset into the corners to generate the pressure instead of glue to make things easier

There are a couple sources to get modified parts but 20$ although sensible for the time required to mod, isnt really justifiable for me, and whenever i try it myself it never works out. Ive been toying with the idea of making 3d printed pneumatics that already have lower friction requirements to move, and have wider ports. What im struggling to overcome though is what to do about the nature of 3d prints. The surface finish may look smooth, but it definitely has substantial friction to it when rubbing other parts and if i smooth it with sandpaper then i lose my tolerances. I have not found anyone else trying to do this or anyone else selling ready made lpe valves that are injection molded, likely because so few people want them. Any insights to making something like this would be appreciated because im stumped on how to make a valve design like lego's work in the same or similiar form factor.
