I made this spectrum analyzer/music visualizer recently. It's meant to be easy to use by just going to the URL and looks great on a 4K screen, jameskdouglas.github.io/frequenSee/

For some clients, electronics for a low impedance guitar pickup (pick up all the signal then process it later instead of building in filtering to the pickup).

And an automated design app that turns a 3D model from Fusion into something that's easy to change the parameters on. That way people can easily just type stuff in and move on to manufacturing. This started for staircases - for companies that make like 20 sets of wood staircases on site every day they want to turn that 1hr of drawing into 60s of data input.

A mostly vibe coded(since I don't plan to ever go commercial with it) app for music composition, which I suspect real musicians would mostly not like..

You can create patterns, play those patterns on a specific beats, add melodies(HTML tables of notes!) with lyrics, add chord changes to determine how the patterns are played, etc.

It's meant to be CAD-like, so you're working as high level as possible, not looking at some raw notes and having to go look up what chord it is every five seconds.

There's plenty of features that don't exist but look like they do, but it does work.

I'm continuing work on my Saas for hairdressers.

I'm happy to say I'm no longer stuck on endless little business logic decisions. Now I'm mostly stuck on essentially creating a (more) complicated google calendar interface. (React + MUI) I stopped work when everything was still wonky but i could quickly make appointments on the fly with it. A few days ago when trying to wrap my head around my own code i kind of regretted that decision. It's a bit more complex of a UI piece than what i've tried my hand at before and my current holdup is (re-)implementing proper drag & drop to edit appointments after i rewrote a piece of the underlying stuff.

I'm an app developer, and I've had such a terrible experience with deferred deep linking providers like Branch and Appsflyer that I decided to build a competitor - https://DeepLinkNow.com

Why I think it's good: deferred deep linking has become an also-ran feature for MMPs whose primary focus is tracking users and advertising.

It's so bad that I can't even open deep links for Tiktok on my home network, because onelink links are blocked by adguard.

So that's why I built DLN. It's brand new and open for beta testing, I'd love some feedback and feature requests + to know how people use deferred deep linking.

I'm working on an alternative frontend for GitHub https://githero.app/

The focus is on providing a better experience: faster, with smoother interactions, with higher information density and a lot more focused on your daily work (with features such as bookmarks and drafts).

It's web-based but there will be also desktop apps (thanks to tauri) that will integrate with your local git.

If you start using it and want to ask for feature requests or notify bug reports please go to the discord server: https://discord.gg/RHCJvUSbr5 Thanks!!

This weekend I’m working on mobile app that allows you to upload photos and it turns everything into a stitched anime (ghibli or not) with movements and eventually sound and script. Great to make mini animes from your day or travels or anything.

Just partnered with an old friend. We want to see if we can tackle movie recommendations in the streaming age. Exited to begin the journey. https://pressplay.app/

I was getting stuck in some manager <> direct report situations and wanted to figure out a way to practice tough conversations, so I started putting together https://practicecallai.com/.

You can choose from common difficult scenarios or create a custom one and get connected with a conversational AI voice agent to practice. Started out with just manager use cases but now testing out sales calls, interviews, pitches, etc.

Mostly built on Replit (would recommend - is amazing & keeps getting better) and relying on a mix of ElevenLabs / OpenAI / Anthropic for the voice & LLM tech.
