24 alternatives to I made a little digital circuit simulator that operates on PNGs
This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!
This digital circuit simulator enables users to design and test logic circuits by creating PNG image files, then simulating them through a Python interface. Inspired by Minecraft's Redstone and the Piet programming… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made a little digital circuit simulator that operates on PNGs launched in 2022; newer entries below may have overtaken it.

Inspired by games like Turing Complete/Virtual Circuit Board/Logic World, I tried to make a mix of aseprite and wiredworld/wired-logic, the idea being the user can build a digital circuit using a "fullstack" pixelart creation workflow. The circuit is just an image. The primitives are (i) connected wires which have undefined, 0 or 1 state during simulation (displayed brighter or darker in function of the state) and (ii) NANDs, which are little pixel triangles. During simulation the user can interact with any wire by clicking on it, toggling its state, which is cool for messing…

Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

I'm enthralled with using pen plotters to make generative art. Last August at SIGGRAPH, I built an interactive experience for others to see how code can be used to make visual art. The linked blog post is my trials and tribulations of linking a MIDI controller to one of these algorithms and sending its output to a plotter, so that people may witness the end-to-end experience.

I am a Dutch high school student and last year I had to do a large project of my own choice. Together with two other guys I decided to do a project about digital logic. We had an ambitious plan: building an 8-bits computer. At that time I started learning programming and I already knew some HTML and CSS. So we decided to not build a physical computer, but one running in a self-built simulator. I was going to build the simulator, the other guys took care of the computer. I was hard, our school hadn't taught us anything about computers and programming so we had to learn everything ourselves.…

Took a break from the falling sand simulation blog posts this week to work on another small project. It's a little pixel world generator- each time you visit, you'll see a new little world. I really like this stuff and had a blast building it yesterday!

Fun little side project I built after learning about circuit bending in cameras for intentional glitch effect. It is browser based camera toy where you "rewire" CCD pin pairs, turn knobs to get different glitch artefacts in real time to capture as photos. I had fun learning to simulate different pin modes - channel split, hue/phase shifts, horizontal clock delays, colour kill etc. Here are some photos taken: https://glitchycam.com/gallery I intentionally leaned towards skeuomorphic design for nostalgia. I miss the days where I'd spend hours making a button to look like a…

I built this educational game to help people identify and understand dark patterns in digital products. It features 10 interactive scenarios based on real-world examples. The game includes: • Interactive pattern recognition scenarios • Explanations of psychological principles • Simulated real-world examples with guided feedback Built with Next.js, TypeScript, and Tailwind. I'd especially appreciate feedback on the educational approach and scenario design.

I built ChipBuilder to make computer architecture more approachable through interactive puzzles. You start with basic logic gates like AND, OR, and NOT, then gradually combine them into adders, multiplexers, memory, an ALU, and eventually a complete CPU. Once you've built the hardware, you can write assembly programs that run on the processor you created. The game is inspired by courses like Nand2Tetris, but everything runs directly in the browser with a visual circuit editor, simulations, and progressively harder challenges.

VoxelChain is an experimental tool to create voxel worlds in the browser. The lighting is fully ray traced in real-time and there is powerful cellular-automata based programming system, which allows to create complex digital circuits and model the behaviour of voxels (behaviour such as falling sand or water). Technology wise, I'm using WebGL2 for the rendering and the simulation is coded in C89 and gets compiled to WebAssembly (with multi-threading) using Clang. The simulation is basically a custom cellular automaton and is fully parallelized. Once WebGPU is released, I'm planning to run the…
