Vast majority of the hardware, especially as it's running on ESP has already been done for you

>Assembly is just a single screw, for a single PCB. The injection mold has generous draft, no slides.

Says everything

I would be curious what “ Have a strong anti-counterfeit strategy.” looks like in practice

How is fulfillment not a nightmare?

Oh, if that’s how you build hardware then sure, hardware isn’t hard to do at all.

Another happy customer, bought two Jamcorder units. Not just the hardware is simple, the software as well: it just works, quietly in the background. I just had to enable daily auto-reset otherwise it eventually had issues. Whenever someone starts playing piano, it records. The iOS app is so nice, playing back on the phone or on the piano, and keeping track of total hours played and organizing favorites. Congrats, if only more projects kept things simple and useable!

Does anyone know what kind of anti-counterfeiting techniques he used?

Reading these kinds of stories always make me happy. Well done!

Ok are you riding with two huge boxes containing all your work on an electric unicycle and I guess the hi-vis top means you're headed into traffic and the box-cords seem to be balancing at the halfway point of the boxes and this is too much anxiety for me. But hey, glad you optimized for minimalism on the PCB ♡

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.
