A screen reader for linux. My aim is to carry around my Raspberry Pi 500 or some other mini keyboard with a tiny computer embedded in it and have it serve as a fully functioning computer.

My hope is to make it easier to use a computer blind than with my usual workflow with a monitor.

I'm working on a new app for creating technical diagrams - https://vexlio.com . It's an area with some heavyweight incumbents (e.g. Visio, Lucid) but I think there's good opportunity here to differentiate in simplicity and overall experience. I'm still in the fairly early phase, and I suspect I haven't quite found the best match of features to customers yet. From a dev perspective this area has a ton of super interes…

really nice work. I'm going to give it a roll!

Not as exciting or big as some of the projects on here, but just a small personal one I’ve been wanting to do for a while.

I recently impulse bought an Epson receipt printer, and I’ve started putting together a server in Go to print a morning update every day. Getting it to print the weather, my calendar and todos, news headlines, HN front page. Basically everything I pick up my phone for in the morning, to be on paper rather than looking at a screen first thing. Very early days but hacking away and learning escpos/go! (Vibecoding a lot of it)

I’m building an open-source project (with a hosted option) that lets web and mobile devs add LLM-powered features with zero backend code. Current platforms like Vercel still require at least a backend serverless function even for basic LLM integrations. This handles key management, access control, usage tracking, rate limiting, message conversation state, etc so devs can focus on frontend.

I just finished playing with my Shimano Di2 groupset and the e-tube app. Last year researchers revealed that a simple replay attack was possible to shift someone elses bicycle. My bike was delivered with updated firmware that is no longer vulnerable so I had to find a way to downgrade the bike. The e-Tube app only allows updating the bike, but it detects root, emulators, frida-server or changing the APK and then crashes. I had to find a way to circumvent that and use an SDR to do the actual attack

I've been working on Splice CAD – an in-browser cable-harness designer.

https://splice-cad.com

Building cables for multiple personal and professional projects, I was frustrated by having to cobble together harness diagrams in Illustrator or Visio, cut snippets from from PDFs for connector outlines, map pin-outs, wire specs, cable constructions, mating terminals, and manually updating an Excel BOM.

Splice gives you:

An SVG canvas to drag-and-drop any connector or cable from your library to quickly route and bundle wires. Assign signal names to wires or cable cores.

Complete part data Connector outlines, pin-outs, terminal selections (by connector family & AWG), cable core colors & strand counts, wire AWG/color.

Automated BOM & exports parts-ready diagrams, wiring drawings, and a clean BOM in SVG, PNG, or PDF.

Connector & Cable Creators. Connectors or cables not in the existing library can be added with an optional outline and full specs (manufacturer, MPN, series, pitch, positions, IP-rating, operating temp, etc.), then publish privately or share publicly.
