Code for a Lego Mindstorms Dalek, from Doctor Who, using the Mindstorms EV3 brick running ev3dev.

With a Logitech C270 webcam:

Taking a selfie in the mirror:

1. Install ev3dev Stretch using these instructions, including the steps to set up SSH and update apt.

2. The following commands use a local copy of the SD card for the rest of the installation; this is much faster than running on the EV3:

   a. Plug the SD card into the computer, and find its device name, typically /dev/sda, /dev/sdb, etc. Assuming /dev/sda, run:

   sudo umount /dev/sda1
   sudo umount /dev/sda2
   sudo dd bs=4M if=/dev/sda of=dalek.img
   sudo chown "$(id -u):$(id -g)" dalek.img

   b. Remove the SD card.

   c. Ensure qemu is installed; assuming Ubuntu 24.04, run:

   sudo apt-get install qemu-user-static

   d. Chroot into the image:

   mkdir dalek
   sudo losetup -P /dev/loop0 dalek.img
   sudo mount /dev/loop0p2 dalek
   sudo systemd-nspawn -D dalek --resolv-conf=bind-host --user=1000

   e. Inside the image, run:

   git clone https://github.com/calliecameron/lego-mindstorms-dalek
   ./lego-mindstorms-dalek/utils/setup_ev3.sh
   ./lego-mindstorms-dalek/utils/install_dependencies.sh
   exit

   f. Unmount the image:

   sudo umount dalek
   sudo losetup -d /dev/loop0

   g. Write the image back to the SD card using the same tool used to install ev3dev.

Select lego-mindstorms-dalek/run.sh from the brick's file browser (or you can run it through SSH).

1. Make sure the Dalek and the computer are on the same WiFi network.
2. Find the Dalek's IP address (displayed on the brick), and in your browser go to port 12345. E.g. if the Dalek is 192.168.0.2, the address you want is http://192.168.0.2:12345.

1. Connect the controller to the brick via bluetooth.
