Experimenting with attaching other devices to the Romo. The idea was to use a simple velcro patch to attach a little light sensitive instrument to the front of the Romo. That way it could make a noise depending on how much light was going into it.
It did work. It was ok, but not that interesting. However, it means I can attach other stuff to Romo and do some more experiments at some point. Which I will do.
