Get a good power supply,
I run 200 Raspberry cluster.. each power supply powers 40 Raspberries.
My power supply is 220v in / 5v out 60A
but you need to get a good brand, this is just an example link : http://rgb-123.com/product/5v-60a-power-supply/
Is it possible to further explain how did you distribute the power to each RPI? GPIO/USB?
I am thinking of using multiple pi+camera arrays, which need to be positioned at some distance from each other, still trying to find alternative solution. One method was to splice ethernet twice, to inject & to GPIO, a bit complex, appreciate your insight if there's easier solution, thanks
