I redesigned my mini game to use the new CH32X035 chip. It supports full speed USB mass storage now, got an LDR for new features and runs an interpreter that I developed on livestream. Unbelievably productive week I would say

Writing a custom ASM, its compiler _and_ its IDE - that's a Herculien effort! Incredible. Astounding.
sounds like Terry Davis
@@joedoe3688 it is much less effort than writing an OS. still impressive though
Assembler, not compiler .. which makes it pretty easuly, actually. I've done it a few times. It's not easy to come up with a GOOD instruction set though.
Did we really get rick rolled 12 seconds into the video? 😂
I think it's his new sthick
Yes. Yes, we did.
As is customary.
We got Bad Apple'd 0 seconds into the video
Yes, life is nothing but one big Rick Roll.
Love how QFN soldering is just SMOOSHING the part on there and it works
great way to create shorts
It is really so much easier to solder than qfp it is not even funny. With QFP if you get solder high up between two of the legs you're basically screwed. With QFN you just drag a fine tip soldering iron along the bottom edge and any excess is gone.
It's not, this is just how unskilled people do it.
@@supernovahm1178 Nope. Its how people who need it done quick do it.
Right, you can decscribe then as you like but this is highly unskilled and would not pass for production anywhere, and especially wouldn't pass for a warranted product.@@Alpine_flo92002
Forth would be perfect for this, and implementing a custom Forth isn't too complicated, though there are no doubt a few open source Forth VMs already implemented for RISC-V. Of course, doing it yourself is always the most fun. I would suggest exploring Forth, even if just for some inspiration with your own VM/language.
I was just writing that his language looks like a low level forth. It’s obviously a stack based engine like forth.
1:50 One trick I learned is you can invert your if statements and write the returns first, and leave out the else. This way your code won't become as deeply nested and looks better
The errors might be from windows writing to the mass storage device in an "optimized" way, it can be turned off I think
Very excited about this project!
Flashing Text on 5:51
*Because of an oopsie
Thanks! I slowed down the video and spammed the play pause but still couldn't catch it lol
Same. Screen recorded it on 0.25 and then scrolled through until I got it 😅
it's a single frame at 60fps (16.67ms long)
amazing that human eyes can read a few words at such speed (maybe after a few attempts)
Amazing work, well done!
I recently designed my first PCB and also used fusion to design a case, however instead of using an image of the pcb as a canvas and tracing it, I exported the PCB as a .step file from KiCad and worked around that 3d model in Fusion. Worked out well, PCB fit first try.
I hate ads but I really do like JLCPCB! Used it several times. Fast, cheap and accurate.
Edit: Geez Louise this is advanced stuff! Very cool, new subscriber here.
This is so cool. I wish you published more videos
Wow. I've really seen a lot of stuff in the domain over the last few years - but this is next level. Best regards from Stuttgart.
Awesome video! Just one suggestion for next time, maybe don't flash text on-screen for a single frame (like at 5:51), it's only an inconvenience to people who actually want to read the text. Just a minor nitpick though :3
ts, pf! it's a mistake, it's the chapter headers, there's more of them, presumably on a single frame each. and then you could use the video slider, you know, "frame-by-frame" function.
@@christianlingurar7085 On desktop it's easy. The left and right arrow bracket keys go frame by frame. But on mobile it's virtually impossible to find a single frame like that.
@@christianlingurar7085if you read the text, it says "*because of an oopsie". I doubt that's a chapter header lol
The aggressive rick roll was super funny
There were some options for languages for tiny processors. One is Berry, interpreted directly on the processor, another is Millfork which is a middle level programming language that compiles to different microprocessors.
The assembly language looks like a low level version of forth. It’s obviously a simple stack engine. Very cool!
Duuuuuuuude. Every upload is a banger!
"A CASE IN FUSION" -- sounds like a prog rock concept album hehehe. ooo can jlcpcb print the liner notes?!
You beat me to it - I had also planned a MicroController Bytecode. This looks great!
Amazing work!
Amazing work 👍
This is good stuff man.
Jolly good show old bean.....cheers.
Ayyy new bitluni vid!
my tip for creating cassses is to also get a model of whats going to be inside the case, that way its easy to check if you forgot anything.

Oh nein! ❌️
Oh no! ❌️
Oh nye! ✅️
So cool 🎉 Thanks
you are a genius man
Oh my god, you've tinkered with those mini black and white CRTs? I saw them a bunch a few years ago, and I was fascinated. I'll have to check out what you did with them. And maybe finally learn how to make my own electronics projects.
You are a genius!
Parabéns! tem poucos projetos sobres Lcds no youtube.
Abraços do Brasil.
Very cool, and great talent. And I also wonder why? If you use a c/cpp compiler it will also run the same code on any mcu?
Damn, this is just pure wizardry.
When I try writing a program for one of these somehwat obscure chips like the ones from wch or bouffalo, I get completely overwhelmed. The sdk is almost always lacking a lot of qol features with everything relying on low level api that I have no idea how they work because documentation is non existent and whatever examples there are, they are most often lacking and way too complicated despite doing something very simple. No tinyusb and certainly no arduino usb but some sort of custom library or library I've never heard of to do everything from setting up descriptors to sending and receiving data all in low level apis and from a single "example" file. Sure, I could get a blinky working, but this? I struggle understanding how you even figured a lot of the obscure parts of how to program them.
Reaching this level of arcane magic with all those powerful spells has always been my dream. Yet the complexity never seems to end. I truly admire all the work you do.
And btw, there is a thing called pikapython which I think can run on mcu with as little as 2KB of memory (and binary size is also small).
bitluni ? YOU ARE A SAINT!
Thank you for sharing this information! Maybe you should offer a 1-Week "Handson" pcb design as a teacher, i would happily sacrifice 5 days of my free time and book you as a presenter/teacher?
Just an idear if you want to kick of something more..
Best regards ;-)
Like the way you oriented the LED's, envy your skill with coding. I can just manage to configure Marlin code. Please do many follow ups.
Just a fusion tip, rather than importing an image and having to draw all around the place, export a step file from kicad and so long as there are 3d models for the parts then you'll get a 3d model of your board and everything. Much easier to start with
Could you please do a series on programming. I know about functions and syntax of commands but not sure how to combine properly into a efficient workable program . Thanks
Hi! Very impressive! Where have you learned all that?
hey, how about to design stackable led panel. so you put multiple boards side to side to make larger screen. and microcontrollers for every board should sync to display one image. would be cool. like MiniLED screen
sir can u guide how to start vlsi and start building custom chips and also how to select components to design brand new board
Now to the interesting question. Do DIY tube stars like you have groupies? But where would your back stage be?
if the part is 3d printed at @250°C, you can do whatever you like with a soldering iron @250°C
Interesting. Remembering that QFN involucre are not recommended for solder rework.
Du bist sehr klug!!!
I'll have to look at your bytecode and see how plausible an implementation on my system it is.
I would also love to be able to do what you do, it is very interesting to me. Where did you learn how to do this? I have an engineering background, but not in EE. This is fascinating to me.
You can use blender with the CAD drawing add-on, if you already know blender.
Jetzt fehlt nur noch ein einfacher C-Compiler der das in Dein Assembler übersetzt und das ganze wäre dann perfekt !
I also need to do a switch to a pro CAD software, been making my 3d prints in cinema4d hahah
I don't see any flexible resin options on jlcpcb, I'm confused o.O maybe it is still curing and you have to put it in the sun for some days :D
Awesome , 🎉
I saw bad apple I needed to watch this
oh maaaaaan the impact resistant plastic i am still laughing out loud
Congrats on the byte code work! Just make sure you don't force tabs on people like arduino did with spaces. I abandoned tabs years ago because they encouraged me to be reckless in my code writing. I started programming in 1967 using IBM punched card mainframe computers. Most of my micro controller designs in the 1990's required me to write an assembler for each new chip.
Assembly programming has become a lost art form. Good on ya!
Tabs are still great, it's this modern trend on forcing multitudes of spaces that's such a pain. Programmers should be free to choose 😊
@@rashidwinter Exactly.
Hey, where can I see the stream where you create that asm?
8:36 why some of the "random" LEDs are slightly blinking even if they are not fully powered?
Power Bloughr to save the day!
Wow how wonderfully silly !
What is the "impact proof" material made from? is it 3D printed!?!?
you did WHAT? I gotta check out that assembler right away! (oh god, I am so unworthy...! ;-> )
Could u link the Mini hotplate that use?
The 🐐
Blender is nice. I'm using Fusion and want to switch to Blender
Is it possible for you to just write an LLVM target instead?
Remind me to mr. Tony Fourcroy, author of BUFFALO, bit user's fast friendly aid to logical operation.
Awesome project, man! Loved it.
And TIL you have a live yt channel too! Smh 🤦♂️
Sorry, but did they ask you about the polarity of a light-dependent resistor?
A good runtime for this class of devices is Pawn scripting language.
What I really with... after long time odrer my own PCb
We have a version with native USB firmware upload like an adruino, its janky but it works, lemme know if you want me to send it
dont have any programming pins exposed on the board... (very quick text = "*because of an oopsie")
❤
Wouldn't a rigid case be better here since the PCB is rigid? Otherwise the case might flex and the pcb gets damaged internally. Not sure about that, but that's my intuition
What's wrong with Blender?
It doesn't support parametric modelling, and isn't as good as CAD software for engineering tasks. With CAD, you specify dimensions, radius, bevel radius and such without bothering with vertices and the topology of the model. It's a completely different paradigm. Blender is really really good, but it just isn't made for engineering in the same way as say Fusion 360 is.
Here is where platformio comes in, using arduino framework without their terrible IDE and with many cores available, you can even write core/platform yourself.
20usd is a lot to money to me still tbh lol. I can’t justify the shipping so I choose standard and go insane waiting for my package for a month
Of course he played Bad Apple on it. Of course.
Why an LDR? Why not a phototransistor or a photodiode?
The characteristics of an LDR are way to slow for any communication...
Bitlunatic ;)
Bad appled and rickrolled wow
Does one get rick rolled if the resolution is too low for perceiving it, unless told or know from previous videos, that it's a rick roll 🤔
It's kind of like the question about the tree falling in the forest with nobody around, I think.
Exactly 😅@@tdhoward
Bad Apple ran on this? Its official then, that its capable enough to do anything we want to do now, WE CAN CREATE THE WORLD!
Micro: TENCENT oder 10cent (0,1 USD)
You are a underrated genius. You are the top 0.001% of humanity. I'm talking possibly Tesla your brain works way different than most.....
Fantastic video, but one small request: please stop flashing messages for such an absurdly short length of time. If you want it legible, please make it legible. If you don't want it legible, please don't put it in at all! Have a great day!
Управлять 240 диодами по 16 ногам! Моё почтение. 0 1 Z. Led = N*(N-1)
I was extremely impressed until i found out that you use tabs instead of spaces, smh /s
Great video, WHERE'S DOOM !!?!?!??!!?!??
Did i just got rick rolled.
diy circuit assembler. support for who. not you. them. and you could just do the case from sheet plastic, and bend it and melt it and make the holes. by hand.
if you want to play with fpga gpu's, you can ise a terasic DE10 nano soc platform with linux on the arm processor to test it. 110K logic units. maybe a few gpu cores like in a desktop system.
Please msell some
Definitely a bit looney!
Rick roll

lmao bad apple
People love USB C and it can power it as well?
*Abstract*
This video documents the redesign of the creator's mini game device. Key changes include the use of a CH32X035 microcontroller for native USB support (enabling mass storage functionality) and the addition of an LDR. The redesign was manufactured and assembled by JLCPCB. The device firmware was developed to support a new mass storage device feature and an interpreter for the custom-developed assembly language, luniASM. This interpreter will enable a consistent gaming experience across various device platforms.

Just kidding, amazing work!
you paid $30 for 10 3d prints? i know they're your sponsor, but if you don't have an SLA printer you could've just ordered something locally. i feel like calling this a no-brainer is just a blatant lie
