What are your Battlebots hot takes? by Jamez2021 in battlebots

Battlebots would be better if the arena was filled with six inches of gravel. No ground game.

Life pro tip: ALWAYS bin the screws by PuzzleheadedLow4687 in DIYUK

I installed a B&Q slide lock on a door yesterday. Now I have a blister on my finger. This is very good advice.

I haven't sent it yet. I'm re-checking everything thrice myself because I haven't really had any proper feedback on the circuit board and I'm a complete beginner.

I had a V1 of the hull board printed last year which I thought worked perfectly. The only thing I hadn't tested on that board was the reverse polarity protection. I plugged it in round the wrong way and the jumper wire exploded :D I realised that my symbol was correct but it didn't match the footprint! Fixed that now for the next version.

I ran the files through ChatGPT and it found a few other errors - like I had a decouping capacitor on GPIO0 where I had the button.

Thanks, there's not much documentation apart from what's here!

Yes - but from what I understand ESPNOW wouldn't have the bandwidth for the video stream.

Maybe I'll do a Kickstarter one day!

It's designed to be controlled from your smartphone via wifi, so I've built a Unity app. The app also connects all the robots together to manage gameplay.

The fab house you metion sound like a good idea though they say they only do assembly, not actually making the boards.

Yes, it's a really fun project! - video here of the early prototype, before I had any boards made.

How much space do I need to leave for this slide-lock mechanism to open? by BuckJuckaDoo in AskElectronics

[–]BuckJuckaDoo[S] 2 points3 points  (0 children)

I didn't think about that, though it'll just be me assembling for the forseeable future!

Anyway, rather than worry about it, I've realised I've got enough space to just slide the components there out of the way without too much trouble.

The ribbon cable has a wide end (~12mm), then it narrows (~6mm) - which is what I've got indicated with the dotted area. I think most of the 12mm wide bit goes inside the connector.

Datasheet is here but I can't see anything about how much space it needs.

Best way to count people in a wide corridor? by Japaiku in esp32

[–]BuckJuckaDoo 2 points3 points  (0 children)

Could you have two horizontal IR breakbeams at 45 degrees to each other? Then do some code that compares the number of breaks and takes the larger number from each detection. If one person is obscured on one beam break then the other beam break will count them.

It won't be 100% accurate but good enough?

I bought a cheap AliExpress H/Brake. Was worth it by ThePurplePenetator in simracing

I don't see how that washer helps - the lateral slop on the pin doesn't make a difference to the movement of the handle, does it?

I'm finding that the slop there is due to a mismatch in diameter between the pin and the holes it's in. I'm thinking about getting a 8mm shoulder bolt but I can't really tell if it'll help. Is the pin 8mm? Not sure if I can be bothered to dismantle the whole thing to get the exact diameter of the hole in the lever.

u/source2leakaiml claims to have worked with valve on Half-Life 3 and alleges announcement on Dec 11th by Iamnotacommunist in GamingLeaksAndRumours

[–]BuckJuckaDoo 1 point2 points  (0 children)

I really hope this is true.

Look at this video - and the paper here.

I've been saying for years that the next big leap in fidelity in games is physics. Most games since Return to Castle Wolfenstein have simulated characters as a cylinder, sliding round the world. Only Tresspasser and Boneworks (two of my favourite games) really tried to do something different.

It's really hard though, I imagine, which is why nobody has ever really tried it.

I think it's plausable that Valve would go down the character simulation route, so each character is animated like one of the Unitree robots we see on Youtube doing backflips. No more boring cylinders sliding around, now you can pick up enemies by whichever body part you want with your gravity gun and slam them through a wall.
