Trying to learn electronics from the bottom up, currently going through „Practical Electronics for Inventors“ (4th ed.). Great book, but not really as practical as the title implies, the base theory chapter is really, really long (but also very interesting)!

Initially started as WhatsApp Team Inbox. But, now I am adding telegram bot, emails and MCP support. Eventually, I am going to add like Messenger, Instagram, Line, Viber, Discord, Slack, etc...

So, it will be a bridge between your/your business communication and AI via MCP. If you want to create your own agent you would be able to create as well.

I vibe coded mostly, but once a while I go in and refactor heavy.

I'm building a RSS <> Discord syndication tool called [FeedSync](https://feedsync.net).

It's pretty simple to set up and is designed to "just work", set and forget.

Recently, I've been experimenting with an Elixir Lua runtime (https://deflua.com/) to build custom feeds by parsing HTML, which has worked exceedingly well, so hoping to release that soon.

It's an extremely niche product, but has been growing well organically, which is nice for a side project!

I'm woking on AgentSpork, a permissionless public board where AI agents request help, respond to each other, and review how well tools support agents. I'd love any feedback from y'all (or your agents) on the idea or implementation. Inspired by recent emergent agent swarm message boards, but hopefully in an aligned way!

I’m building a website for discovering first names that’s enjoyable to explore: https://abracadanames.com

It started with a family member telling me they were frustrated with existing websites. What I noticed is that in many cases they feel cluttered and not smooth to use, almost like a 1-to-1 translation of the underlying database queries, where they have you choose filters and sorting options upfront then browse the paginated results.

I wanted to avoid all of that by creating a different experience; I built an interactive full-screen wall UI with infinite browsing so that most of the screen space is dedicated to the core content. I worked on the name sampling algorithm to try to make it as enjoyable to browse as I could, and the only filter displayed by default is the one to select genders.

More advanced queries are available through the search field which supports natural language queries, running on a local multilingual interpretation engine with a cloud LLM fallback. The database engine is custom built with Rust, compiled to WASM for higher performance when running on CloudFlare Workers. I don’t use an external DB service for names today.

What I’m pretty proud of is to know a lot of technical work is hidden behind that UI, and how it has been shaped by the experience I wanted instead of the other way around.

The lullaby is cute but extremely annoying after a while, give me a way to disable it!

Thanks for the feedback! You can now disable it in the new “Experiences” menu.

I saw an interesting article posted here on HN about Go's Swiss Tables implementation. I'm writing a small C library to use them for fun, so you can use any byte array as a key. Either a C string, a number, a bool, etc.

I'm vibe coding a toy chatbot with OpenCode and GLM 5.3 - I'll open source it once it's meaningfully done (keeping the repo private for now until I am _so so_ sure there are no secrets in it!). This has been an exercise in learning about lots of new AI SWE concepts including some tech (Mastra, LangSmith, DeepInfra) - as well as a chance to try some open weights models. The actual useful output is an iteration loop orchestrator based on GitHub issues/PRs which I have found a lot of fun to use. That'll also be open-sourced.

I'm making a stair lift for my Roomba. It fits into a small box and you can retrofit it on any stairs. I got sick of carrying it up and down manually and didn't want to buy one for each floor. It also carries my laundry up and down.

I am working on solving Prompt Injection!

I am building a new kind of LLM runner which lets you understand the internal reasoning process, and which can be automated to intercept hallucinations and prompt injections before they cause more damage.

(No public code yet, but I do intend to open source it)

My friend and I built Alineo (https://github.com/DrejT/alineo), an open-source framework that provides the core building blocks for orchestrating secure sandboxes and harnesses for AI agents from scratch.
