(May 2026)"]]>I’m an application developer by day, but lately Claude Code and Codex have finally made microcontrollers approachable enough for me to start tinkering with them on the side. I built this little “holographic” display that shows the surf forecast for any beach. While my friend built the casing, and mechanical part of it

My only concern is that it’s able to get 90% of the way there for productionized ready code, but the last 10% is starts to fail at when the tech debt gets too large.

Have you been able to build anything productionizable this way, or are you just using this workflow for rapid prototyping?

The same way to think about exploring a 2d plane in a 3 dimensional space where the 3rd dimension is constant. We just happen to be in a random big bang in this 5th dimensional space

A way to store bookmarks all in one place similar to Pocket, but built around semantic feature as the primary feature. Been beta testing an iOS app, but need to pivot on the name since there’s another Recallify on the App Store, and haven’t gotten around to it due to not much user growth.

I’ve been experimenting with embeddings by building Recallify, primarily to help me quickly retrieve obscure things I’ve read online. Even at just 1024 dimensions, it’s impressive how effectively embeddings capture and surface ideas based purely on semantic similarity, rather than exact keyword recall (which I’m pretty terrible at remembering). It’s been a game changer for turning fuzzy mental concepts into actionable insights.

Beta testing an iOS app for it if anyone is interested: https://recallify.app/

I’ve recently bought a mini PC for small projects like this and have been loving being able to host with no cost associated to it. Albeit it’s probably still incredibly cheap to use a IaaS or PaaS but still a barrier to entry for random projects I want to work on a weekend

It uses natural language as an interface to retrieve what you've learned in the past with direct connections to the source of truth. There's also a perplexity integration to keep chatting with what you've retrieved.

I like to use it as a smart bookmarking tool that you can save niche utility hacks across reddit, hackernews, Twitter/X, or anywhere across the web. Consolidate all of your saved materials, and bookmarks into one place where you can easily find what you've saved from the past using natural language to search across your knowledge base.
