An interesting little robot, but it has a huge drawback. You designed the whole thing wrong. Motor mounts made from an injection molding are used for installation by holding the gearbox, not the motor! With an assembly like yours, these gearboxes will be destroyed very quickly by anything that gets between the gears.

@concretedog7427 9 ай бұрын

You can use the clamps over the gearbox in the same way as the commercial ones with a standoff. Or indeed we could design a mount that has a gearbox cover. I've run them a lot as they are and they are pretty resilient.

It's a great project. A very similar system in the former GDR, "Vero Construc" was one of my favourite Toys during my childhood years. This system hadn't beams, but blue cubes. With this cubes it was possible to create beams from braces. The braces were made from wood. What do you think about make braces from lasercuttet wood. I think it would be more efficient (less plastic and time) to make the braces this way instead of printing 3D.

@concretedog7427 11 ай бұрын

Basically when the wings are in the stowed position the two smaller horns on the wings form a small V slot (where the pressure of the elastic bands wants to rotate the V closed as the wings open) the wire then sits inside the V and the horns press against it but the wings can't open until the wire is pulled out of the way and the V can cross each other.

They should produce another version without the lock-down but in a very distinct colour so it would be easy to spot in an exam hall. It is a huge pity that all modern calculators are hobbled to meet education requirements. I really miss the good old days when calculators were made as good as the chips and displays of the time allowed for a professional market! Colour displays are another regret well illustrated on this video as the display has to distractingly blink off after a timeout period to avoid the battery drain.

I carry a really low end multitool with an adjustable wrench in my laptop bag. Your Nextool Vanguard here is so much nicer, but the one I carry was selling for only $3 on Amazon when I bought it, so I can't really complain! When I did IT work, I always carried an adjustable wrench in my laptop bag next to my screwdriver multitool. The number of times when I would drive or fly to one of our locations and sit on a wobbly chair or at a wobbly table was way too high. You can really improve someone's tiny office when you make their table stop wobbling by tightening a bolt. Sure. You can tighten a bolt with the pliers, but I always feel like a cave man when I do that, and sometimes you just can't easily tighten a nut or bolt well when you also have to squeeze really hard.

Splendid that, an adjustable can be infinitely useful - I love a good multi tool myself for all the random things I also get up to, and I carry three with me usually. A pliers based multi-tool from Stanley, a cheap one with a hammer head on it (for the drone landing pad ground pegs), and a swiss army 'knife' for general scissors, pliers, screwdrivers etc, although I don't carry any of them for the knives on them, they are all legal. I have often wondered how many I can reasonably account for if I were ever stopped though.
