I setup a meeting indicator using a raspberry pi zero w
- Raspberry Pi Zero W I bought the one with headers pre-soldered because I suck at soldering, but if you're comfortable with solder you can likely save some 💵 here.
- Mini-HDMI Adapter
- 2.5A Power Adapter
- A Mini SD Card with Noobs pre-installed
- Pimoroni Unicorn Hat Mini
- Raspberry Pi Zero Case
- Something to mount the case on the wall, I used these 3M Command Tabs but they might be a bit OTT.
