Transit detection

Finally, we let the orbit pass around the lamp and measure the light intensity as a function of time. Whenever the orbit passes in front of the lamp, the brightness goes down a little, but does not become zero: a very good analogy to the planetary transit.

Prototype 2018
Experimental set up 2019
(in the meantime, the plate is laked black and the lamp is better)
