I've worked on optimizing serial displays, and I think I see your problem. I think you are sending a lot of overhead with each write. i2c works by sending and address, a command, and data for that command. If you are only writing a single byte at a time, 2/3s of the transmission is completely unrelated to what you actually want to display. Instead of only changing the bits that change per frame, store a frame buffer on the computer's side, and write to the entire display at once. That would change it so that only 2/1027 bytes are overhead, and that should give a decent speed increase.
@@gorgpflug6087 I'm not talking about changing the i2c transmission speed, I'm talking about increasing the goodput(ratio of relevant data to irrelevant data) of the bus.

Not gonna lie, I actually got emotional hearing and seeing bad apple show up here. Its such a cultural touchstone for so many people and touhou music became such a big part of my life for so many years. Overall it just fills me with joy seeing it used for demonstration purposes.

Try blue noise comparison (static) instead of Floyd Steinberg to dither. You can also try 3D blue noise or Nvidia precomputed spatiotemporal blue noise, but given low frame rate, I think static would work better. The problem is that the movement in the dither is obscuring the movement in the picture. With a static dither, maybe you'll be more successful with partial screen updates.
this seems like a good idea, but would probably need something more, to be worth making a new video about, and given how at first this was like april fools video, and then he made a cool case for it, then now what, fix the dither and...what, use another of those screens, to make a micro model computer with functional screen?
@@jan_harald Oh I do believe mitxela could figure this out! You're right that it doesn't look easy to build a video about, at a glance. However, I didn't expect this one, either =D What I would do personally is "here how the code was massively improved" - there's def some things that can be added, including partial refreshes (look up micropython SH1106 driver for simple page-based example) to increase FPS. In addition to that... 128x128 could be done with two displays, I suppose! But, AFAIU, mitxela's videos aren't software-focused typically? so I'd understand if this were to be left as exercise to the reader.
@@AryaFairywren didn't he just specifically talk about how he made it only send the updates to the screen? both at one point, and then demoing it at the end, how if only the mouse moved, it worked just fine? and rather than bigger resolution, I'd rather take lower resolution over bigger screen size, to make it more legible, lol, right now it's basically just tiny noise, even at a terminal prompt
Also if you need it for any future projects feel free to use my video edit of bad apple specifically designed for these displays: th-cam.com/video/7XijCqWb5TI/w-d-xo.html
I dont know if you can change that, but if the dithering is slowing down the performance, maybe switching to indexed dithering would help. Floyd-Steinberg dithering is acumulating data in an iterative way, while indexed or lookup dithering is done per pixel and way faster. as a bonus you would get a nice retro pixel art vibe
The proper way to use that style knurling tool is to pinch your part between rollers, using the screw to apply pressure. Doing so puts almost no load on the lathe itself, and therefore won't damage it. A lathe is not really meant to take heavy loads in the direction that a pressed knurling tool generates.
I have not seen a music box mech like that before. With the rotating strikers it looks as though you can actually adjust the sustain of each note by varying the rotation speed. Wicked!
🛠 The knurled brass HDMI connector looks super sleek. I never thought about customizing connectors like this, but you make it look both fun and doable. Also, the tech details you shared were really insightful. It's amazing how you manage to blend craftsmanship with tech so seamlessly. Can't wait to see what you come up with next!
Sir i just discovered your channel a few months ago, and i have to say that your channel is very special, thank you so much and i wish you all the best
Dunno what the hell I just watched, but it's earned you a sub. That's a work of art. It might not be much use for playing DOOM, but it works quite nicely for the video of Bad Apple.
Uhhh, what? That's a 20+ year old Touhou track, "Bad Apple!!". It's been a meme for these low resolution displays for almost a decade now? Just like Doom. :P
The commentary toward was the end was amazing ,(first video if yours I've seen)... a thicker backplate for the screen and a screen protector (thiugh idk if steampunk) would add some polish. Love it!!!
What would make this even cooler is if the screen was amber, like a few old school monitors are, but I'm not sure if anyone manufactures small screens in this color...
omg its so coooooooooolllll!!!!! I love all things steam punk!!!! eeee keep up the amazing work also love the break in the music for an explanation also if you mark your work as ASMR you may get more views if you havent already

From the department of “but why would you do this?” comes another amazing creation.

Could not have said it better!
That i2c abuse is one of the best backwards uses of a technology I've ever seen. Kudos.
that's DDC
@@fffUUUUUU For what it's worth, DDC2B uses the I2C protocol.
would have used SPI, might actually have a decent bandwith and the controllers supports it natively
@@Flowxing I don't think the video card can speak SPI but you're right if this were microcontroller driven
@@big0bad0brad oh I didnt know this was directly driven by the gpu, I thought there was a controller inbetween
this brings a whole new territory to those tiny oleds people use to display stats or animations on their pcs

Bad Apple is one of the "testing" videos, just like doom. So it shows up everywhere in tech.

That Bad Apple bit at the end was perfect. The most useless display has a use!

Below the chrome should be a copper layer, which - when exposed - would look even more steampunk.

Someone bought a mill! Congrats! Btw, I am sure, you know how the "pinch" knurling holder should be used.
I was wondering the same thing and I figured someone would point it out
What a coincidence! I was just on a binge of your old content. Great as always, keep up the good work!
This is absolutely stellar. This is my kinda ridiculous! It does make me want a more real gooseneck display for showing chat while I'm streaming...
What a cool project! Loved the bad apple part, keep on doing what youre doing!

You should put a ridiculous fresnel lens in front and make it look like the screens in the movie Brazil
I would add a ink-stained microscope slide in front of the screen to protect it and change it away from B/W
I dont know if you can change that, but if the dithering is slowing down the performance, maybe switching to indexed dithering would help. Floyd-Steinberg dithering is acumulating data in an iterative way, while indexed or lookup dithering is done per pixel and way faster. as a bonus you would get a nice retro pixel art vibe
Indexed can also be readily performed on a pixel shader due to its nature.
Always happy to see another version of Bad Apple, and always happy to see the Midi music box.
Yes, i use PoH (Power over HDMI) on my monitor.
What size? Does the hdmi have enough current?
@@309electronics5 It's just a joke about he is not connected anything except HDMI.
Well, HDMI does pass 5v so...
@@NaddlyCOnly at a measly 55mA though. Difficult to power anything much bigger than this 😅

AWESOME! The Bad Apple Demo at the end - That's what i wanted to see on this display from the very beginning of the movie.
in case anyone was wondering- the drums in the background track are the default club samples in FL studio
I really do admire this esoteric TH-cam channel, absolutely stunning!
Is this the start of ThisOldAlex? and well done, you made me laugh a lot with that punchline
Honestly this is pretty close to the sorta shit I'd be coming up with if I had my own workshop. Living vicariously through you right now.
i never expected to see "steampunk" and "HDMI" in the same sentence

“A weight off my solder” is such a beautiful song, i had to go back and listen multiple times. Wow.

Really like that music. Something different and not so overused. Keep it up!!!
Thank you for this wonderful rendition of bad apple!
This video has all the good things: music, technology, mill, lathe, brass and fine work.
The Bad Apple remix and display made this worthwhile. Got really nostalgic here. Great job!
amazing. And holy crap that music box demo at the end
The performance of Thus Spake Zarathustra on the piano makes this ending just so much better.
We leave you alone for five minutes and you become ClickSpring.
Seriously tho this is legendary
Nothing bad with that!
Nice swing in sound track!
