# Skycam

## Overview
Raspberry Pi 4-based webcam

## Specs
* SoC - Broadcom BCM2711
* CPU - ARM Cortex-A72 @ 1.8 GHz
* Memory - 8 GB LPDDR4

### Disks
Device | Partitions _(filesystem, usage)_
--- | ---
SD card | `/dev/mmcblk0` (ext4, NixOS Root)

### Networks
- DHCP on `10.0.1.0/24` subnet.
- Tailscale on `100.64.0.0/10` subnet. FQDN: `skycam.mesh.vimium.net`.

## Devices and connections
- Camera Module 3 with wide-angle lens

## Building
To generate a compressed SD card image for Skycam, run:
`nix build '.#nixosConfigurations.skycam.config.system.build.sdImage'`

Once a card is imaged, the existing SSH host keys should be copied to
`/etc/ssh` manually to enable secret decryption.
