#702I am sharing what I learnt building electric cars. On YouTube: https://youtube.com/@foxev-content In a learning app: https://foxev.io/academy/ On a physical board where people can explore electric car tech on their desk: https://foxev.io/ev-mastermind-kit/ Backstory: from 2018-2023 I converted London taxis to be electric and built three prototypes. We also raised £300k and were featured in The Guardian. I have a day-…
Thanks for sharing. I watched some of canbus video and came back to say it looks really interesting. I am building a prototype diesel electric autonomous vehicle for farm applications at the moment so the videos are somewhat relevant to me.
Thank you means a lot :)

#703I'm building an AI DJ for Spotify called Listen to Luther. It's open source here: https://github.com/jacobheric/luther. Currently it responds to prompts with a list of songs that can be queued, played or added to playlists on Spotify. Next I'll give it proper memory and the ability to adjust and remix on the fly. I built it because I was frustrated by the mostly passive experience of Spotify's own AI DJ. There is no path to commercialization here as Spotify's TOS does not permit it (I asked them). So I host it for myself and a few friends and made it open source for anyone who's handy enough to run it themselves.

#705Working on an interactive SQL tutorial for intermediate+ SQL developers, introducing you to and showing the power of such concepts as JOINs, pivoting (flipping rows to columns & vice versa), subqueries and common table expressions, including recursion, UNIONs, row locks, and some other small things.
The thing will be browser-based and, hopefully, both entertatining and educational.

#706I'm building modular home audio speakers. Wireless, self-powered, upgradeable, repairable. Think Sonos meets the Framework laptop. Check out my prelaunch page here:

#707I am writing a newsletter, https://www.clientserver.dev, which started with the writing prompt “what if someone tried to make Money Stuff for software engineering?” I’m still iterating on the format a bit, but I just crossed 100 subscribers and made the Hacker News front page, so I feel like I’m on the right track.
I had a daughter almost 2 years ago, and for a while I didn’t have any free time. But once I started getting a few hours in the evening, I wanted to start up side projects again. I found it frustrating to work on coding projects in 1-2 hour windows. But writing is a little easier; I feel like progress is a little more linear with writing, and having the Monday/Thursday deadline has helped me just ship.

#708I've started working on a shared shopping list for group vacations. No sign-up, just create a list and share the link with friends. Emphasis on good sync performance even in bad network conditions, automatic sorting of the list based on where food is found in the supermarket, tags for items on the list. If anybody has ideas for this use-case please comment or email me :).
Not exactly the same but this reminds me of an idea I had for shareable shopping carts. You add things to a shopping cart and then you share it via a link (text, dm, chat, email, etc) and the receiver of that link clicks on it and the contents get added to their cart (alternative could be an import button that you paste the link in to make it more explicit). Why? Plenty of times I've been ordering food with friends a…
Actually I really like this idea, especially in the context of shared food ordering it makes a lot of sense!

#709Rewriting the Elixir parser for QueueMetrics live for Teams, my company's service to keep track of call and queue statistics for Microsoft Teams telephony, in a way that's better than the PowerBI examples that come in the box. It's at https://www.queuemetrics.com/teams.jsp?lid=H990
It's quite a mess as we have to aggregate multiple data sources that come with their own timing and sequence issues - plus we are seeing massive adoption so resource usage will be interesting for v2.
The plus side is that building massively parallel and redundant services in Elixir is, if not actually fun, at least more feasible than in other environments.

#710I'm working on https://photoboost.app, a tool that turns a handful of selfies into professional AI-generated headshots. Think studio-quality photos without the studio — powered by LoRA fine-tuning and smart prompting.
The goal: minimal input, fast turnaround, and results good enough to use on LinkedIn or resumes. Currently experimenting with ways to reduce training time and improve accuracy with as little as 5-8 images. Also exploring automatic gender/style detection to optimize prompts while keeping everything privacy-friendly.
Would love feedback — what would you expect from a tool like this? What features or improvements would make it a no-brainer to use?
