Hehe no worries. There’s a distinct lack of assessibility for these little devices. They are so cool to, you can do lots of very interesting projects with them.
I’ve seen so far:
3D Mapper (this is on my list. I’m almost finished… Sadly, I’ve got a degree to finish)
Thermin (Makes various noises depending how close you are to the module. Handy for making ghostly noises of old)
Something I’d really REALLY like to try… REAL TIME 3D motion detecting. Multiple sensors at various points in a room/garden/etc feeding real-time distance scans. You can build up a 3d picture of an area.
That would take some time to do though. Still, imagine that!
