This video is the exact opposite of "hey guys, "! It hit me with such immediacy that I felt a little anxious, as if I'm not paying enough attention. And that's a good thing!
A lot of TH-cam videos fail to satisfy "I cut the side off, hot-glued a Arduino into! Like, subscribe, and donate to my patron guyzzz". It is incredibly refreshing to see content like this. I love it when people reverse engineer the existing hardware. You are legit one of my heroes. Excellent work! I feel like I have wind in my sails.
Wow, I'm glad youtube recommended this to me. At first I was like "yeah, ok, 4 buttons, why are you recommending this to me youtube" but after watching, and checking out some of the other videos, code, microcontrollers, machining, reverse engineering, disassembly, FPGA design?? - wow, finally a channel that goes into the details of the fun stuff, not just watered down for mass consumption. Why didn't I know about this sooner? SUBSCRIBED!!!
Depends i guess. The short circuit buttons will overwrite the lowpass buttons. You could maybe dissern both lowpass buttons getting pressed from an individual button press but in the end it does not matter too much in this application
it mostly acts like it ignores all buttons except the leftmost, but there might be a quirk or two in it.. i didn't really intend for it to handle edge cases like this in any particular way.
As a lifelong coder and electronics nerd, I'm super impressed. As a woodworker, I'm annoyed at how nice the finish on the case is right off the tool. Beautiful work!
I really appreciate your reverse engineering work here. I was able to take the information you gathered and modify my own usb switch, I added an esp8266 to mine and host a simple web server so that I can swap to different machines without buttons. I also got rid of the auto switch functionality.
This is seriously so inspiring. As someone who's teaching myself electronics and programming I'm incredibly jealous of your knowledge. To be able to just pick up a device and reverse engineer it to the point of being able to modify it to your liking seems like an impossible task to me and yet you make it look so easy. Hope you continue to post your work, I'm excited to see what you do next
Great attention to detail and amazing editing! Loved the music, narration, time lapses, and b-roll! Makes me want to invest more effort into my streaming setup, myself!
I just want to say how humbled I am by your knowledge and skill. There is so much expertise being shown in so many disciplines of this 'little' project that, even though I have had the word 'engineer' in my job title for more than 20 years... it feels kind of like an example of verbal irony at this point. I look forward to your content going forward. If any of it is simple enough for me to grok, you might teach this old dog some new tricks.
This neardy video made me click subscribe! It's so cool that people put up videos like these, a chance for everyone to learn new stuff every day. Even without having checked I know that you probably have alot of videos that will come in use in the future! :)
Bummer there's no STM8 support in Ghidra, it's a great tool that has really made my RE skills seem more impressive 😄. Cool hack and glad to see a new video from you! I totally do not understand the circuit Black Magic you worked for the switches and LED s... Nice desktop CNC! It's been a while since I've watched one of your streams, but I've learned a ton from you and your community.
I have no idea why youtube thought I would want to see this, but I must admit that I'm intrigued and this is very much something that I'd like to learn.
I am incredibly impressed with everything in this video. Thanks youtube for recommending this one. I really wish I would get to this level of hardware/firmware understanding at some point. Any tips for good resources? Obviously experience over time is probably the best way to get there.
Made me want one of those cnc mills. Never occured to me that you could totally just use a small mill on plastics and wood and stuff. I always associated milling with metal but delrin is a fantastic material. Maybe when my GME shares explode I'll buy myself a nice little mill 💎🙌
I’ve loved watching this process, the end result looks beautiful, thanks for documenting! Fascinated at how you re-wrote the firmware for the ST chip, really impressive, out of curiosity if the IC wasn’t an ST chip would you have found this process more complicated? Love the cnc skills as well, routing plastic doesn’t look so nice, you are certainly braver than me!
I find it amazing that the USB switcher was running a microcontroller with so much firmware code on it. It seems like the entire device could be driven with a simple counter and MAYBE a 555 timer (to automatically advance if it finds itself on an input that doesn’t come up within a few seconds). But I guess microcontrollers are cheaper than a couple of ICs now. I also wonder what other sorts of switchers are built using the same basic setup and template firmware.
I'm not even convinced that µCs are cheaper in this instance I think it's probable that the development budget was constrained too heavily for a discrete analogue solution. It's much easier to pay an intern/junior tech to turn your fully featured KVM switcher in to a USB only switcher than to pay an engineer to design one from the ground up.
@@TheRealFlamingNinja Yeah, the fact there was an unpopulated IR receiver is also pretty telling. I'm betting the device started life as an HDMI switch.
What what? How? Please explain. Do you mean that you can trigger firmware dumps by glitching the clock?!? How is this accomplished? I am genuinely asking.
@@confusingdalek709 (cool name, btw ^^) Man, I can't put my finger on what it reminds me of. I feel like I've heard stuff from 3epkano, Amiina and other groups that leaned more into the atmospheric side of things, but they're not usually that ambient on average. Thank you for recommending (well, mentioning) Boards of Canada, I'm listening to them as we speak :)
Oh! It's original music by Scanlime, she made it specifically for this video! It's on her Extra Content channel on diode zone. I'm posting the link separately, in case it gets auto-filtered by TH-cam, so you'd at least have this comment :) She called it simply "Four Buttons OST"
Must be one of the key elements if firmware hacking.... being able to judge "this code does something worthwhile" vs "this is just garbage left over from an old codebase".... especially when there's so much of the latter thatit's almost like trying to "map" DNA.
This video is the exact opposite of "hey guys, "! It hit me with such immediacy that I felt a little anxious, as if I'm not paying enough attention. And that's a good thing!
You are a true polymath
No!
It can't be!
Afro, you are still alive?!
Are you planning on making videos again?
it's one of my goals in life to be described as a polymath by someone unprompted & unbiased.
I remember you
hope you make comeback.
What's that?
This is what "hacking" montages in movies should look like.
too much thinking not enough explosions, main stream would never go for it
IT SHOULD THOUGH
I was gonna say the same - I could literally take this video and edit it into a movie scene. I found myself saying "they should act".
this ist like hacking in a database its more like redesigning/modding someting but realy good
When life gives you lemons... flash its firmware and redesign it from the ground up!
Just what I've always said
I was in awe for the 25 minutes and 5 second I was watching this. What a wonderful adventure from being annoyed at a loud button.

IDK why TH-cam recommended this to me, but I love it.
So much work for just 4 buttons. Exactly my stuff!
Simple question: What happens if you press two buttons at once?
It will blow the world up BOOM efery one deadh
Depends i guess. The short circuit buttons will overwrite the lowpass buttons. You could maybe dissern both lowpass buttons getting pressed from an individual button press but in the end it does not matter too much in this application
Magic smoke.
just dont do it xD

What an amazing skill-set you've developed.
the music in this is fantastic. it makes it all feel like a grand mystery being unraveled.
The algorithm brought me here and I like it.
Hooray, a new scanlime video! Totally worth the wait, love how this project turned out.

Yay you're back; I have so much been missing watching your videos: half technical deep dive and half meditation. Thanks Micah!

Can't give this enough thumbs up! Excellent work, Micah. I miss the chat and the streams.
This presentation style is so unique. I love it. You are like the "Applied science" of aesthetic.
No way this was 25 minutes! I know pretty much nothing about what you did but I was still super engaged!

absolutely gorgeous video and process... thank you for taking us on this journey
Nice project and relaxing video. There's a little bit of everything in there. Well done.
Very impressed, great music too. Keep up the good work!
l’m glad TH-cam show me this godlike bigbrain channel. Thanks for the video.
when i grow up i want my job to look like this.
I've watched this video 6 times. So inspiring! Thanks for sharing.
Absolutely amazing. I envy your amount of patience.
Great job! Love the firmware disassembly and milling!
A thing of beauty, a joy forever. Great video, its content like this that gets my subscriptions.
This is amazing! Thanks for the video, I'm surprised I haven't seen your channel before!
oooh, this video is sweet! I love seeing these kinds of breaking-stuff-down-tryna-hack processes
Love the editing on it too! And that CNC buffing to smooth out the plastic amazed me.
"In today's episode of DIY or BUY..."
Good to see you back. Was wondering where you had gone.
stumbled on this video accidentally, but... very glad I did, really enjoying the content
First video I see of you, love the style
the frame blending in the timelapses of you cadding looks so smooth compared to frame sampling
Zen Photon Garden HQZ at 1:37... that project was how I found you way back when. Would love to see more work on the garden someday
this video is such a vibe, love it
I'm lost for words. Props to you!
Never saw something quite like this for long out here, great!🔥💯
It's been a hot minute. Good to see you back!
that mix of making/hacking and ASMR-ish-ness, both relaxing and interesting. the youtube algorithm can be fickle but sometimes it'll give you a gem.
Wow! Plastic, wood, 3D printing, laser cutting, circuit design, hardware hacking, programming. You can do everything!

I am definitely smarter for having watched this. Thanks!

Glad to see more videos! Long time no see 😊
Could you do a video of your work bench area?
Amazing edit of an amazing project!
I wonder if it wouldn't be easier to just build one from scratch. But I'm happy that you didn't.
This so far for 2021 is the most satisfying video.
That was incredibly impressive. Subbed :)
Very impressive work !
Hahaha your face looking at the cnc mill through the mill webcam :DDDDDD
I loved that moment too
One of the most brilliant and inspiring things I've ever fucking seen.
Woah new scanlime
right?! I was just looking if a new video was uploaded _yesterday_ lol
Very nice editing !
Love the mix of materials used. Was that Delrin? And those mills seem dang handy. And I missed seeing Tuco!
22:58 she says "delrin base"
@@HybridChickun D'oh! Thanks!

Quite the adventure!
Also thanks to the almighty algorithm for bringing me here.
That is unreal. Good Job

welcome back!
Really great execution on the single piece wood construction. It looks really good. What cnc machine are you using and how do you like it?
Nice music, great for background stuff when you're concentrating on a project!
Anyone know what it is?

That's awesome! :)
Thank you for sharing, too! 🖤
Damn that's cool. What a brain. And this is the short version, how long did it take you? Truly amazing watch your projects. My new favorite channel.
Very cool, I love this type of hacks... loved the one where you used glitching to extract firmware form tablet :) More of these pls
What what? How? Please explain. Do you mean that you can trigger firmware dumps by glitching the clock?!? How is this accomplished? I am genuinely asking.
Holy shit your circuit design is so fucking clever!
22k subs?!? Not enough! Take another~
Very nice, looks great!
This video is amazingly good! Like, this is a real ass piece of art you've made. What's the music? It's hypnotizing.
I'm also wondering :)

WOW. Amazing video.
*EDIT*
You should upload more!
It's been a while. Glad to see the pandemic didn't take you out.
That is truly a work of art 👌
Great job!
i got a headache just watching her. shes amazing.
this is my kind of ASMR
Not sure what I just watched but dangit it was cool.
There are four lights!
New upload, great :)
