Step 4Second type - components needed
You need the following components:
- 2 pieces of thick copper wire
- copper tube (our tube was chromed - harder to solder)
- an iron ball (e.g. from a ball bearing system) - of course it must fit to the tube
- soldering-iron and some solder
- a bit of hot glue
How it worx?
As you change the position of the sensor (a few degrees from horizontal) the ball rolls to one side of the tube (that damned gravity... _) and if it's the side where the central contact is (made from the wire), the ball makes electrical contact between the tube and the wire - and that's it!
