Stacked Raspberry Pi's with common power
From CaveLab
This is a gallery page — meaning that it contains mostly images, with little or no supporting text.
In the early days of the homelab I experimented with using a common 5 V power supply for all my Raspberry Pies. I later switched back to using individual AC adapters, it was just easier. But I am playing with the idea of revisiting this in the future, using a computer power supply. That will provide both 5 V for embedded devices, and 12 V for my stack light.
