in the first place, the anal0g flow3r is a tribute to it's big ancestor [the 2023 CCC camp badge "flow3r"](https://flow3r.garden/) ([social media on mastodon](https://chaos.social/@flow3rbadge)).

the anal0g flow3r is a much simpler analog 5 stage ring oscillator in the form of a flower with 5 petals. each LED will slowly light up in amber, turn off again slowly and pass the light to the next petal.

a beginner's soldering kit.
