A few weeks ago my ridiculous kilopixel wooden pixel display went a little crazy on the internet. I wrote about the response and the experience as a whole, and feature some of the …

I had some down time when the Y axis stepper motor managed to unplug itself overnight!

Oh yeah I love split flaps! Even considered them for this project but they're cost prohibitive and that idea is already out there. The sound those things make is just perfect.

Hey, I know you! Thanks for checking it out, looking forward to seeing you at the next PHP×MSP!

$250!

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 differen…

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?

It was indeed < 1 day

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.

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…

I was extremely pleased with that discovery! Needed something a little grippy, pliable yet firm, and disposable.

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 origin…

Western Wisconsin, Eau Claire. It's beautiful here

Pretty quiet! I spent some time figuring out how to make sure the stepper motors don't whine (the answer is microstepping and decent motor controllers). The pixel turning is very q…

Rozin was a direct influence on me! Seeing his stuff ~10 years ago got me thinking about unorthodox displays.

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 …

Genius. I'll do this when I install it in my Zoom background and take it off the internet

Oh I kinda love the idea of drawing the next one based on the pixel diff! Would be fun to game that queue.

TTFP will surely be < 1 day

That it, the method will forever be called the Vanna White Method

Yes! I have an RGB sensor that could handle that, but it's more bulky than the simple IR on/off sensor I went with. Could be four colors, or four shades of a color.

y'know, I've been excited / feared that Bad Apple would show up. The good news is a lot of frames would probably just be a few pixels to change from the previous frame, so some mig…

I think I might put this in my friend's coffee shop but I'll restrict access to people in the coffee shop. Not going to let the internet get a hold of that. In addition to the user…

I don't think I want to think of the actual cost per pixel - especially the cost of my time! I have deliberately avoided accounting the final cost
