We can all combine our own knowledge, enthusiasm, and AI to do amazing things. It's like using better computers with better processors. For programming, I could perfectly well use a PC from 2001.

I admire the entire community behind reverse engineering iPods. I'm active in various community channels, sharing information with them. I wouldn't be an engineer without using the tools and knowledge of those who came before me.

Here are some details about how I made the iPod Classic 6G emulator and what I encountered along the way: https://x.com/DMonteroCrespo1/status/2095882094455009695

Hi, I wrote that note by hand; I didn't use Claude. The hypotheses were based on the fact that other emulations used different paths to reach the playback device. For example, I analyzed Rockbox to see how they managed to play music on

Some improvements are still needed, but the idea is to run the original Apple firmware without modifications. I'd like to be able to run it on a Raspberry Pi Zero someday... a very thin layer will lift the iPod Classic 6G emulator

Even though I used AI, it took me months to decipher parts of the emulation. I had to study, and I loved learning things I didn't know. It's also a very beautiful learning path; everything related to technology is magical. Enginee

I used AI, and I mention it in the post. I'm also an engineer at IBM, and I know a bit about operating systems and embedded systems, which helps me understand and decipher parts of the iPod. I also have a small workshop where I was abl

I didn't know that, it's a good fact. When I had my iPod 6G, that album art animation looked amazing.I haven't been able to unlock it because it has many upgrade directions that I haven't been able to decipher

I saw your work and I thought it was excellent; that's another step I want to take: being able to run the games and the cover flow! We're one step away from making the iPod free forever.

One of the things that gave me a lot of trouble was unlocking the music player. Reverse engineering it was really difficult. I investigated many possible variations, tried searching on https://freemyipod.org for memory register

I've been developing a QEMU emulator for the iPod Classic 6G (Samsung S5L8702) that boots the original, unmodified Apple retailOS. Navigation, the disc, the screen, and the music library worked for a while, but the music player appeare

I recently saw a video about this, and it happened a few years ago. But today we don't rely so much on GPS to locate an address. Thousands of devices around the world connected by antennas can calculate proximity better than a GPS

We are currently in discussions to see if we can emulate that device in the velxio.dev electronics emulator

It's a bit crazy that they used characters as markers to detect the use of Asian countries. I think in the near future they might change the intelligence of the model based on where you live

I tried the Arduino + RC low-pass filter example (using PWM as a DAC) and it was pretty impressive to see the output voltage actually smooth out instead of just flipping between 0 and 5V What I found interesting is that the ADC reading foll

Velxio 2.0 is live. A free, open-source emulator for 19 embedded boards: Arduino, ESP32, Raspberry Pi, RISC-V , running real compiled code in your browser. The best part: it's fully local. No cloud dependency. No student accounts. No d

Creator here! Just saw this was posted. I've been working on the 2.0 release to move beyond simple AVR emulation. Integrating QEMU for the ESP32 and Pi 3 (Linux) was a massive challenge, especially maintaining sync between the differen

Hi HN, I recently spent some time going through MiniMind, and it’s a remarkably clean resource for understanding the modern LLM stack under the hood. It’s a minimal, end-to-end implementation of a ~25M parameter GPT-style model in pure PyTo

Thanks, I didn’t know about Renode.I’ll definitely take a look. The reason I’m specifically exploring JavaScript is because of a project I’m working on (velxio.dev), where everything runs in the browser, so having a JS/WASM-based appro

One thing that’s been particularly frustrating is trying to find complete documentation for Xtensa. I’ve looked around quite a bit, and it feels like there isn’t a fully open, detailed spec available. Most of what exists is either partial,

I’ve been looking into this space recently while exploring ESP32 emulation. I came across this repo: https://github.com/lcgamboa/qemu/ which is quite interesting, but it’s not really a JavaScript/browser-bas

I've donated about $100 USD to it. KidCAD is great software because many engineering systems are too expensive for students. Another very interesting project that's gaining traction is the Arduino emulator https://velxi
