> What can I build with an Arduino that isn’t better, cheaper, faster, and more complete as a full product on Amazon? Almost nothing.

I mean, my little hobby project is making the LED strips taped to my skis respond to an accelerometer, so they pulse brighter when I make a good turn. Plus Bluetooth control of the patterns. Not gonna find that on Amazon.

Love it, and I agree. I've built two "star skies" for kids, using cheap RGB LED lights, programming them to slowly change color, only use warm colors, and turn off more and more stars over time. Nothing super fancy, but very custom to my needs.

Please blog and post about this. I need a how to.

If I complete the project! Haha.

There are plenty of not-arduino microcontrollers that can do this.

To your reply-writer, how do you think those products came to be, many of them are productization of hobbiest projects.

The arduino project jumpstarted a whole ecosystem, but I don't that ecosystem needs arduino anymore.

It sounded like OP was saying they couldn't think of any interesting things to tinker with since everything they could think of is already a product on amazon. So in this case it isn't about alternatives to Arduino, it's about alternatives to reactive LED lights for your skis.

Sure. I'm responding to this bit:

Mine's on a nRF52840 board. My point is less about Arduino and more about tinkering.
