I launched Quiet UI this week:

https://quietui.org/

It prioritizes accessibility, longevity, performance, and simplicity.

With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.)

Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode.

All form controls are form-associated via ElementInternals and work with native validation APIs (required, pattern, etc.).

Dialogs, popovers, tooltips, etc. use Popover API for top-layer access without having to portal or hoist.

Some of the more fun components include: Joystick, Stamp, Mesh Gradient, Flip Card, Random Content, Intersection Observer, Typewriter, Lorem Ipsum, Slide Activator

The library is free for personal, educational, non-profit use. Commercial use requires a license.

Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics.

I've been playing guitar for a little under 6 years and ran into the common problem among many intermediate guitarists fall into, which is stagnating into a plateau at a certain BPM.

The most effective solution I've found is to take the top speed hit playing a chunk of a lick and simply increase it 20-50 BPM past that limit, attempting one's best to stay in tempo. Regardless of how sloppy it sounds. Then roughly halve that increased addition of BPM, it will become relatively easier to play. For example, if you are stuck at 120 BPM, upping it to 150 BPM with sloppy attempts, then dropping it back down to 130-140 BPM.

I've gone cleanly from alternate picked 140 BPM triplets to 220 BPM triplets in two months after being stuck at 140 BPM for over a year with this method. Sometimes even hitting 280 BPM triplets when I have the focus and time for it.

Even then, I want a more consistent, and variable way of customizing a practice session using a metronome from a hobbyist perspective without using a DAW. With a simpler interface for doing so. As well as encourage with said method above for other guitarists in the pursuit of speed.

Currently bootstrapping a SaaS side project: https://diplomium.com

Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation.

The bigger picture: Certificates are often the only tangible outcome of a learning experience. By making them verifiable, permanent, and easy to distribute, organizations save admin time while learners get a trustworthy credential.

Status: Running for 2 years, used by schools and training centers in Latin America. Now building AI-powered features for design editing and data extraction from PDFs.

I’m at a crossroads with my Speed Cubing Competitions listing app (SCComps.com). It’s an iOS app built in Flutter, has around 250 downloads, and currently generates no revenue. I'm spending about $500 a year just to keep it running. There’s little community engagement, and I'm debating whether to double down and rebuild it in Swift—or just shut it down altogether.

Everyone’s drowning in long articles, dense PDFs, and hour-long videos. I’m working on https://unrav.io , it lets you flip any article, paper, or YouTube link into the format you actually want (summary, mindmap, podcast, infographic, etc.) in one click.

Right now I’m experimenting with a simple bookmarklet trigger instead of a browser extension. Curious: how do HN folks feel about bookmarklets in 2025, still viable, or do you prefer extensions?

Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI.

I am currently working on a new mode that is more like what played walking around: a few rounds in rapid fire, very little time to think before the next round.

We're building a repairable and sustainable e-bike battery at https://gouach.com :)

That's pretty cool. It's nice to see this exists.

For me, I'll probably send an email later to support to ask (no rush, since it's out of stock anyway), but I was checking for info on compatibility with Yamaha (e.g. my Cross Connect) ebikes. It's not on the compatibility list. They make their own (mid-drive) motors (PW-SE on mine I think) and proprietary batteries. They pulled out of the United States market altogether so getting more batteries from them again is doubtful. (Mine currently charges to ~85% and then throws an error code, but it still works for now.) It is a Yamaha 500Wh36V battery pack on the down tube with 3 wires (I just unscrewed where the battery plugs in to see).
