First, I gathered four Raspberry Pi 4’s. I say “gathered” because I already had most of them lying around, so I just picked up a fourth board to round out my set. The thing about Raspberry Pis is, they’re easy to accumulate. I see this as a giant plus. I don’t know if my boyfriend shares this enthusiasm.
With the Raspberry Pi 4, it’s critical that you use a 3amp power supply if you don’t want the board to get throttled by power limitations when under heavier loads or using peripherals. After that, there were just a handful of other accessories to order. Many of them I already had around, like the network patch cables and the switch.
Reduce, reuse, recycle
I highly recommend you cannibalize your own existing stock rather than ordering new for this project, since it’s just a hobby build.
