A binary clock only needs 9 leds. With multiplexing, that's just 6 leads. With #Charlieplexing... five?
So, either an ATTiny with some kind of decoder chip, or a slightly larger ATmega chip?
Oh, maybe this!!! https://www.adafruit.com/product/3677
That could even drive the LEDs individually, no multiplexing!I wish I was better at #soldering. It low-key terrifies me. 😆
I could maybe bodge a design for a surface-mount LED board and send it to pcbway and have them a$$emble it?!? 🤷♂️

Как я сделал брелок на ATtiny13, научил его трем гипнотическим режимам и превратил в набор для пайки
Представьте: маленький брелок лежит в кармане. На нём — мордочка кота из популярного мема. Нажимаешь кнопку на затылке — и в центре головы загорается круг из двенадцати ярких SMD-светодиодов. Два огонька начинают бегать по кругу с коротким хвостом. Ещё одно нажатие — и запускается спиннер: три луча вращаются по часовой, потом три круга против. Третий режим — маятник, три светодиода плавно качаются взад-вперёд, как загипнотизированный взгляд. Четвёртое нажатие — и всё гаснет. Батарейка CR2032 отдыхает. Всё это работает на самом дешёвом микроконтроллере ATtiny13. Четыре пина управляют двенадцатью светодиодами через Charlieplexing. Никаких Arduino, никаких сдвиговых регистров.
