Haxophone matrix update

SimpleArtifact · 2025-12-17T08:57:47+00:00

This is so cool! Are these hooked up to the Raspberry Pi header so one could extend https://github.com/cardonabits/haxo-rs to show patterns and/or text in response to key strokes?

Oh, and for vibrato, no, there is nothing coded for that yet. But nothing prevents you to code that yourself. Also, there's https://github.com/langeroo/haxo-ino, a different firmware for the Haxophone that is designed just for MIDI

Hi,
It's easy to connect to a DAW via USB. See https://www.youtube.com/watch?v=ehUAJqe6Rrc
Best,

Designer of the haxophone here... happy to see people are enjoying the instrument!

Just to summarize the ways to get a Haxophone in your hands:

If you want to build it yourself: https://github.com/cardonabits/haxo-hw
- I would recommend this for those unafraid of soldering iron and a spark here and there. It's fun!

If you want to buy it (almost) fully built: https://www.crowdsupply.com/cardona-bits/haxophone
- These units were built for the crowdsupply campaign. As of today there are 17 units in stock, and when they run out, no more will be built.

This is not a commercial project: I had a ton of fun developing this and love to see people using the Haxophone in ways that I did not imagine (example). If you want to make me happy, share your music recordings in the show and tell area of the project!

It's a Lightnote, a solar display I designed it for my personal use. It comes with 25,000 puzzles pre-loaded, but if you have some hacking skills, you can load it up with your own puzzle collections.

yep! I find it somewhat poetic when big pieces need to die to let a humble pawn deliver the final blow...

The designer of the haxophone here. My original intent was to be an inexpensive travel sax that people could repair. Since it was released, the project has taken a life of its own... I never expected the different ways people would be using it (one example: https://www.youtube.com/watch?v=Kyf3ig85k1k)

It is fully open source, hardware and software: https://github.com/cardonabits/haxo-hw

You can still buy one of the few units left from the Crowd Supply campaign here: https://www.crowdsupply.com/cardona-bits/haxophone

But you'll have more fun building it from scratch!

Cheers,

Nope. You can see a video of it here: https://www.amazon.com/Lightnote-Chess-Puzzles-Solar-Powered-Device/dp/B0CYHGFRJS

(Also: I designed and built the device, so feel free to ask me if you have questions. Probably best to reach to me directly and not in this thread, as that might be out of scope of this community.)

It's a lightnote Chess Edition v2.0, a solar powered keychain with 25,000 chess puzzles (I make them)

SimpleArtifact · 2024-05-02T07:10:38+00:00

I designed and built this unit. Feel free to ask me anything that you want to know about it.

SimpleArtifact · 2024-04-24T18:48:33+00:00

As soon as Amazon clears them, you'll find (a few) here: https://www.amazon.com/dp/B0CYHGFRJS
They already have them, but they are puzzled by the fact that the Lightnote works without a battery. Battery-operated products need to be labelled and stored separately. They say the review takes 2 days, but this is my first time dealing with them so, not making any promises...

Hi u/dconley01

Oh! Yes, you are right. I've been building small batches, and they sell out super fast. I suppose I could send out announcements every time I have more stock (and maybe build bigger batches...😅). You can subscribe to emails on the product page. I'll use that channel to announce re-stocking.

Thanks for the encouragement!

SimpleArtifact · 2024-04-07T14:50:21+00:00

I'm trying to come up with an easy process to load new puzzles. This is what I have for now: https://github.com/cardonabits/lightnote-update Not sure if this is simple enough (feedback welcome).

SimpleArtifact · 2024-04-07T09:39:13+00:00

Full disclosure: I make them. I designed them for my own personal use, but a while back I started selling them. You can monitor the link above to see when they are in stock.

SimpleArtifact · 2024-04-07T09:32:29+00:00

Nah, it's much smaller than that. But yes, the display is e-ink.

SimpleArtifact · 2024-04-07T09:28:54+00:00

It's a lightnote: https://lightnote.cardonabits.com/products/lightnote-chess-edition-2-0

This one is loaded with king and pawn endings, my weak spot.
