+Stappenplan:
+
+* Hang lasers. Connect all cables etc.
+* `DISPLAY=:0 cargo run --example laser_frame_stream_gui`
+    * Use numbers to pick a nice shape. Use this to make sure both lasers cover the right area. (if it doesn't work. Flip some switches in the gui, the laser output should now start)
+* In trap folder: `uv run supervisorctl start video`
+* In laserspace folder: `DISPLAY=:0 cargo run --bin render_lines_gui` and use gui to draw and tweak projection area
+    * Use the save button to store configuration
+/*
+* in trap folder: `DISPLAY=:0 uv run trap_laser_calibration`
+    * follow instructions:
+        * camera points: 1-9 or cursor to create/select/move points
+        * move laser: vim movement keys : hjkl, use shift to move faster
+        * `c` to calibrate. Matrix is output to cli.
+        * `q` to quit
+    * saved to `laser_calib.json`, copy H field to `trap_rust/src/trap/laser.rs` (to e.g. TMP_STUDIO_CM_8)
+* Restart `render_lines_gui` with new homographies
+    * `DISPLAY=:0 cargo run --bin render_lines_gui`
+*/
+* change video source in `supervisord.conf` and run `uv run supervisorctl update` to switch
+    * **if tracking is slow and there's no prediction.**
+        * `uv run python -c "import torch;print(torch.cuda.is_available())"`
