Hey Hackers. This is a project I solo-developed that turns completed PCB assemblies into an easy to use boardview with some accompanying boardscans. There are lots of easier and better ways of doing this, but this is an experimentation to do it as cheaply as possible, with the highest quality and lowest chance of errors. The technical details are in the link. Most public boardviews are almost entirely the result of industrial espionage, other than a few encrypted subscription based software platforms that provide extensive access. The process output is released as donationware, as my main…

A few months ago, I was inspired by this post on Reddit, titled: Food items should have QR codes that instruct the microwave exactly what to do. Like high for 2 minutes, let stand 1 minute, medium 1 minutes.. I thought this was a pretty cool idea, and that it

I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more.…

Hi! I've been working on the flipjump project, a programming language with 1 opcode: flip (invert) a bit, then jump (unconditionally). So a bit-flip followed by more bit-flips. It's effectively a bunch of NOT gates. This language, as poor as it sounds, is RICH. Today I completed my compiler from C to FlipJump. It takes C files, and compiles them into flipjump. I finished testing it all today, and it works! My key interest in this project is to stretch what we know of computing and to prove that anything can be done even with minimal power. I appreciate you reading my announcement, and be…

1. Single universal binary, that can be natively executed on every hardware platform Mac OS X was made for (32/64 bit, PowerPC/x86/AppleSilicon). 2. Minimalistic gadget-style design. If launched as a tool, there is no menubar, no dock icon, no nothing, just the clock window. 3. Support for hidpi and dark mode for environments, that have them. 4. Window title bar for moving the window with a mouse, and a handle to resize it (latter for OS versions, that have it). 5. Can be easily ported to GNUStep and thus other OSes (sources under GPLv3). 6. Simple Makefile build system.

We wanted to do something very challenging to prove to ourselves that we can do anything we put our mind to. The reasoning for why we chose to build a toy TPU specifically is fairly simple: - Building a chip for ML workloads seemed cool - There was no well-documented open source repo for an ML accelerator that performed both inference and training None of us have real professional experience in hardware design, which, in a way, made the TPU even more appealing since we weren't able to estimate exactly how difficult it would be. As we worked on the initial stages of this project, we…

Hey all - this is the software part of my cyberdeck, called the Slimedeck Zero. The Slimedeck Zero is based around this somewhat esoteric device called the PicoVision which is a super cool RP2040 (Raspberry Pi Pico) based device. It outputs relatively high-res video over HDMI while still being super fast to boot with low power consumption. The PicoVision actually uses two RP2040 - one as a CPU and one as a GPU. This gives the CPU plenty of cycles to run bigger apps (and a heavy python stack) and lets the GPU handle some of the rendering and the complex timing HDMI requires. You can do this…

I built a software-defined radio transmission platform that runs on a Raspberry Pi Zero W. It spawns its own WiFi hotspot and serves a web UI — connect from any device and you have a portable RF signal generator with 12 transmission modes: FM broadcasting with RDS, FT8, RTTY, FSK, POCSAG paging, Morse code, SSTV image transmission, voice cloning via live mic, spectrum painting, IQ replay, carrier wave, and frequency sweeps. Everything runs through a browser interface. Upload audio files, type messages, configure frequencies, and transmit. The Pi's GPIO pin does the actual RF generation via…

Made an ARM Thumb CPU from scratch in a digital circuit simulator for fun and decided to push the joke a little further and run real stuff on it, like a Web server, a Scheme interpreter, a MIDI player, and a VT100 emulator. This is basically a how-did-we-get-here blogpost, it's my second one of this kind, I'd love any feedback you might have.

Hi Hacker News, This is definitely out of my comfort zone. I just wanted to show you guys because I'm super proud of it. It's a 100% faithful recreation based off of the schematics, patents, and ROMs that were found online. So please watch the video and tell me what you think https://youtu.be/auOlZXI1VxA The reason why I think this is relevant is because I've been a programmer for 25 years and AI scares the shit out of me. I'm not a programmer anymore. I'm something else now. I don't know what it is but it's multi-disciplinary, and it doesn't involve writing code myself--for…

Zero-Knowledge Proofs (ZKPs) let an untrusted proved show that computation was executed correctly without revealing the inputs to the verifier. However to prove anything, the computation first has to be expressed as a circuit: a system of polynomial equations (constraints) over a finite field. Circuits are the assembly language of zk and every constraint costs prover (and sometimes verifier) time, so production circuits are aggressively hand-optimized. Over the last months, we have been experimenting with writing formal specifications instead and letting LLMs produce the circuits: as long as…

If you've debugged a null pointer exception on a Flipper Zero, you know the pain - the device crashes, you reflash, add print statements, repeat. Memory bugs in embedded C are brutal because they only surface at runtime on the actual hardware. This template lets you write Flipper Zero applications in Zig, giving you: - Memory safety and compile-time error checking - Bounds-checked arrays and explicit error handling - Clean build system that works cross-platform - Integration with UFBT for packaging and deployment - No special IDE required - just Zig, UFBT, and your editor The interesting…

The 6502ctl project is an Arduino controller for the 6502 CPU. The controller controls all 6502 pins, including the clock signal and interrupts, and simulates an address and data bus with attached memory and an output peripheral. The controller includes a clock-cycle debugger with disassembler. An assembler is also included with the project.

After being thrust headfirst into FPGA development thanks to the Analogue Pocket, my first from scratch creation was a gate level implementation of the original Tamagotchi toy. The core, running on both the Analogue Pocket and MiSTer platforms, lets users re-experience the very first Tamagotchi from 1996 with accurate emulation, but modern features. The core has savestates (which is much harder to do in hardware vs software emulation), high turbo speeds (1,800x was the max clock speed I've reached so far), and more. Learning more about hardware and FPGAs is something I've wanted to do for…
