#102Mumbo Jumbo built a similar concept on Hermitcraft using trap doors. There is a revolution going on called "buildstone", using redstone to create aesthetics

#103A refresh rate of 370 microhertz gives "Calm Technology" a whole new meaning. I love it. https://en.wikipedia.org/wiki/Calm_technology
Coincidentally that's also the framerate of the YouTube stream main camera (please fix OP)
I think the issue is that I'm streaming to disk with ffmpeg and recording at 5 fps to save space. OBS must be locked to the same frame rate since it's sharing the webcam?
My original concept included two webcams, one for OBS, one for ffmpeg. Guess I should have gone with that!

#104This has to be the the most expensive cost per pixel display I've ever seen. And I've never loved a display more. This is absurd in the best possible way
> I created a reciprocating poking mechanism that uses a flexible glue stick With the most cost effective and creative "wear item" ever.
I was extremely pleased with that discovery! Needed something a little grippy, pliable yet firm, and disposable.

#105This is pretty cool as-is, but I can't help but try to think up ways to increase the speed. (Not the point, I know.) I feel like it should be able to do a whole column pretty quickly with some optimizations. If the device that turns a block could do so without needing x-axis alignment to change, then you could do a whole column pretty quickly. Or perhaps it'd be better to do rows instead of columns, since the y-axis…
Thanks for thinking through it! I've found that moving left-right is a little noisier and has a little vibration - up-down is smoother. However, it's not that noisy and it'd be fun to experiment with different algorithms for finding the next pixel.
Re: Show HN: I spent 6 years building a ridiculous wooden pixel display
#106I keep trying to imagine "faster" variations. What about some system to shoot wooden spheres into a tube or channel for each scan line, selectively feeding different color spheres. Some combination of gravity or pneumatics to drive it. So a scan line would flush out one end and refill from the other. Then scale it up to a stadium size unit with bowling ball pixels. I guess a challenging part would be proper timing to…
Your idea is not too far from marble pixel art machines... https://youtu.be/w1ks0Vy98KI
I love this project! I was well on my way with the kilopixel when I find him or it would have given me pause.
He's optimizing for some very different things though.

#108I'm working on something similar, but 3D and faster motion: PinThing / TAP (Tangible Actuated Pins) [1] "Motorized pin art display" is what i'm going for... The problem with passion projects: Progress is never as much or as fast as I want, though! Hard to find the people who want to throw money at things like this and/or buy them. And anything mechanical gets complicated and expensive very quickly. But it's so much f…
I love this so much! Will it be mounted so that gravity makes the pins fall back down or do you need a retraction mechanism?
Re: Show HN: I spent 6 years building a ridiculous wooden pixel display
#109Awesome project! I built a somewhat similar 30-pixel display: https://www.chrisfenton.com/the-pixelweaver/ Mine was entirely mechanical (driven by punch cards and a hand-crank), and changed all of the pixels in parallel, but a lot of the mechanism development looked extremely familiar to me.
This is incredible! I can appreciate how much work it took to make this happen. Well done! I was recently in the presence of some linotype machines from the 1800s and it's so good to be humbled by the achievements of people who came before us. That machine was so complex, I could barely begin to figure out how to manufacture one. Your discussion of looms reminds me of that!
If you enjoy linotype machines, I'll suggest you watch 'Farewell ETAOIN SHRDLU', a documentary on the last night the New York Times ran its hot press system
Re: Show HN: I spent 6 years building a ridiculous wooden pixel display
#110This is cool. I wonder, as you were iterating on the design and development, why didn't you start with a very small grid (10x10) to validate or test different options for their practicality and operation before scaling up to the 1000 pixel versions? It might have saved a lot of time and money, but maybe small scale tests aren't sufficient to work out the kinks?
Definitely! I scaled up to 3×21 to validate some things and immediately broke a lot of what I thought would work.
I tested a 1×10 grid of the wooden pixels to try out some different variations as well.
