Very much appreciating the sentiment in the article.

Is it just me, or is there some kind of unusual photo editing going on in the photo at the bottom of the article? Something looks uncanny valley, related to the bottom of the box on the left side of the photo, and related to the background. Did some kind of "erase background" mechanism go wrong here?

Interesting that is has ESP32 in there - looks like it's becoming the default choice whether or not wireless is involved.

Hope we can read more about this.

>>Now, granted, Jamcorder is -- very much intentionally -- a simple device. I get that.

And let's not forget that. And let's not just follow the headline.

Greetings from a hardware engineer with decades of experience building hard things.

Nice.

If I may ask for your advice on a related subject.

I have an old electric piano, it doesn't register dynamics, the strength with which I hit each note. Which is a huge bummer.

I can't think of a simple way to hack dynamics onto the keyboard, I thought of adding an additional sensor and using the time delta between touching a key and hitting the bottom, but that's not really correct, as you can hit a pianissimo key fast in staccato.

Maybe a basic spring that decreases resistance as it becomes compressed, but it might make keys quite hard, and it's not very simple to implement.

Any ideas?

Thank you.

the amount of crapping on the author that I'm reading bothers me.

whole lot of manufacturing experts on HN today.

It's not that hardware is simple, but the fact that we have inexpensive micro-controllers that pack a giant amount of complexity and let us turn a lot of electronic problems into software problems.

Try building such a device only with non programmable TTL logic.

As usual for these posts. No certifications. No proper markings. Probably non compliant. Will probably go unpunished.
