How does a "sunflower light" work? curiosity teardown https://makertube.net/videos/watch/7e2ee8a3-2e47-45a6-a14c-70c4fd86d29c I recently got this "sunflower light" while searching for stage / disco lighting effects. While it's an interesting effect, I'm curious about how it works and if it is hackable. So lets go exploring! Here's where I got this thing: https://pileofstuff.ca/r/0xbv3 It made it's first appearance in my most recent mailbag video: https://youtu.be/uaFCQlDZqgw My tip jar: https://www.patreon.com/pileofstuff My other tip jar (channel membership) : https://www.youtube.com/channel/UCRiFz3gNKE3VysarZ7nmqIA/join Buy me a coffee (or a beer): https://ko-fi.com/pileofstuff If you are OK with me getting a commission on your purchases, feel free to use my affiliate links: Ebay: https://ebay.to/33IF7PA Banggood: http://pileofstuff.ca/r/9ajsf Some other links to products may be affiliate links #ElectronicsCreatorsThis isn't the only way to do it. It's probably not the best way to do it. But it's how I did it.

wonder how long it would take to be noticable 😛

Microcontroller clocks are not usually exactly calibrated.
