There are plenty of conventional timepieces out there in the world; we’ve also featured a great many that are aesthetically beautiful while being unreadably esoteric. This neat “shadow clock” from …read more (https://hackaday.com/2025/08/10/building-a-7-segment-shadow-clock/)

A Solar-Only, Battery-Free Device That Harvests Energy from a BPW34 Photodiode
https://hackaday.com/2025/08/10/a-solar-only-battery-free-device-that-harvests-energy-from-a-bpw34-photodiode/

Normally when you think solar projects, you think of big photovoltaic cells. But a photodiode is just an inefficient, and usually much smaller, PV cell. Since [Pocket Concepts]’s Solar_nRF has …read more (https://hackaday.com/2025/08/10/a-solar-only-battery-free-device-that-harvests-energy-from-a-bpw34-photodiode/)

Coping with Disappearing Capacitance in a Buck Converter
