I Am Making an 8-Bit CPU in Logisim
Hey HN, I am making an 8-Bit CPU in Logisim and blogging about it.t's nothing fancy, really simple, unoptimized dumb CPU for sake of learning. I am no electrical engineer, I am just a self-taught dude who has programming as a hobby and wanted to dive deeper into abstractions. So here it is, so far I wrote 2 parts: [links redacted] I welcome any and all critique and feedback, as I can be wrong about everything for sure.

all alternatives →- IBI built a mockup/prototype/wireframe editor in ten weeks2012 · ▲42
Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…
- IBI built an open-source kernel for Texas Instruments calculators2014 · ▲20
You know that old TI calculator you used in high school, then put in a box and forgot about? Have you ever wished you had an operating system for your calculator with preemptive multitasking, dynamic memory management, a tree filesystem conforming to the FHS, and all the comforts of Unix? Well, good news: that's totally a thing that exists. I've been working on my kernel for about three and a half years now and I'm looking for new contributors to help out. It's written entirely in z80 assembly, and it's both challenging and fun to work on. There's an IRC channel for contributors or people…
- MHMy HomeLab (and other cool stuff)2024 · github.com · ▲9
Just wanted to make my first post about something interesting I've been working on for some time. Any ideas/suggestions for new hardware or software I should try out are welcome, though I will only have time for a major overhaul in a month or two where I want to redo and document everything a bit better than how it is currently. Hope this can inspire someone to start their own homelab or give some ideas to already existing ones!
- IMI made a OSS alternative to Weights and Biases2025 · github.com · ▲6
Hey HN! I made a completely open sourced alternative to Weights and Biases with (insert cringe) blazingly fast performance (yes we use rust and clickhouse) Weights and Biases is super unperformant, their logger blocks user code... logging should not be blocking, yet they got away with it. We do the right thing by being non blocking. Would love any thoughts / feedbacks / roasts etc

First tutorial to date. Writing your first C program, includes a link at the bottom with a detailed look at printf() as optional reading. I would love some feedback, as I intend writing up a lot of dev articles for people to learn from : www.xanthu.com/first-c-program

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
