The audio from this session was then transmitted the following day, via light, from Butser Hill to the Trundle, 12 miles away. The audio modulates the intensity of a bright red LED and a lens is used to form a beam. The white flashing light on the Trundle is the locator for the LED transmitter, once the LED is pointing towards the white light, the scope is used to align the receiver's photo diode. The output from the photo diode is then converted to audio and played through the Cube. This was recorded live with additional sounds from the MC101.
Future plan is to build a couple of two-way transmitters/receivers, so that light-speed communication can be established between the hilltops. Greater distances are being tested too.
