Crossposting from here where I'm actually writing up a whole big thing. I'm making a moving timelapse camera mount using LASERS and motors and gears. Here are some teasers:

Lasers! (Don't use acrylic)

I've got access to my local hackspace's RedSail laser cutter. It's one of the cheap Chinese options, but at like four grand, it's not really that cheap. 80w, 100x80cm bed I think. You don't really want to go less powerful than that. I've used a 40w one a fair amount, and it's good for etching but not much else. The 120w one was pretty amazing, I was cutting 3/8 acrylic and it wasn't even blinking. Basically lasers are awesome and if you're in a large metro area, you probably have a local hackspace that either has a laser cutter or is trying to collect donations to get one RIGHT NOW.

I don't have the ability to cut steel and I don't want to spend real money on this. I did break a couple of the clips while putting them in, but it's still a lot stronger than acrylic was. Maybe in a month or two, one of the CNCs in my hackspace will be operational. I've been building some acrylic geared stuff, and steel versions would be pretty rad.

Start with looking up local hackspaces if you're in a largish city. Otherwise, services like Ponoko will cut stuff for you, but they're a little expensive and you'll probably gently caress it up the first time if you've never used lasers before. Last year sometime, I designed a machine that needed it, submitted it to them, and it came back like $140. I said gently caress that and shelved the project. When I eventually got hands-on access, yeah, nothing really worked right or fit at first. Six months in, I'm only really starting to be able to cut most of my stuff right the first time. So yeah, if you don't have anything locally, I don't know what to tell you. If you can swing it, I think you can buy and build sub-$1000 40w kits that will definitely get you started. It'll take a while to outgrow that if you've never tasted something more powerful.

Just over two weeks, nice job.

You're doing that for the Instructables contest, right? Someone from my hackspace is using an identical box to make an electronics testbench.

oXDemosthenesXo posted:I've got an oddball question for y'all: This is an intriguing question and I like it. What is involved in the hinges? Is it just a tube with a cutout and a little pin inside? Does that make sense? Does material matter? Are you looking for a one-off? If you are, then I would suggest trying to make your own with some copper/other metal tube and pin, or 3D printing if you have a local source. Ponoko might be a reasonable option for that too, I don't know.

Blooot posted:I did this thing http://www.facebook.com/completecontrolrobot Blown away by how fast you guys put that together. What were the rules like? I'm curious how strict they were on your radio systems. Could you have your bot constantly transmitting a beacon on a second frequency to allow for more sophisticated position-based control? Could you use an autopilot?

What kind of sensors are you using? This might be more techie than is appropriate given the situation so far, but I'd try and set up some data logging as soon as possible to gather metrics, and possibly trigger notifications on certain events. You should totally create a hydroponics thread! I've been vaguely thinking it'd be a fun thing to do, so I Have Some Opinions.

Little bit of lacquer might not be a bad idea.

Are there any good YouTube videos on sanding? This is such a strange question, but getting metal parts I've been building to a mirror shine is surprisingly difficult. Knowing when you're done at a particular grit is the most boring skill to have to learn

BTW Slungblade's old thread is backed up on archive.org with the original pictures, and the thread is especially good when you start noticing that Grover is fairly active and dispensing his housebuilding wisdom throughout

Look up YouTube videos for burning Lichtenberg figures. Should get you started. You're definitely gonna die though, fyi, can I have your stuff?

Might be some decent DC motors with worm gears on Aliexpress, or check out your local junkyard and pull some windshield wiper motors * I don't have any real intuition for how much torque that is

I'm quite allergic to pine, due to growing up in a woodshop basically. Same thing can easily happen to other woods

Get bicolour / strips that contain two temperatures of white LEDs, and then drivers that can fade between them. I don't have great sourcing advice for you - Film stuff is great but hella expensive, I think IKEA has some decent compromise stuff.
