With the serial port added, the connection to the RPi is similar as with the BB and shows like below. The next picture is a screenshot of a minicom session from the laptop to the RPi.
As a result, the schematic setup looks like this. For the remote desktop I use TigerVNC
This is a short video about my RPi and below a picture with the RPi camera and mounted on carton (which has been replaced by small camera stand made of fischertechnik).
The various experiments have lead to several playlists (oldest on top):
Several short tests

19 April 2024: Questions for this episode: can I use an external monitor via de HDMI cable, does the floppydrive work and can I use the raspicam as a second camera? Well, there are some unexpected results. Paying Patrons (Tier 2 and up) can watch the full video of 20 minutes. Click the image to watch the video. See also the blog.
