Sundial
Sundial is a dual oscillator, amplitude modulator (tremolo). Making use of two
NE555 Timer ICs, the circuit outputs two oscillations (two white LEDs)
which have been shaped differently. These oscillations are summed and
power an LED (red). The audio input and output are connected in series
through an LDR (light dependant resistor) - which has a high resistance
when there is no light and low resistance when there is light. This
causes the audio signal's volume to be modulated by the summed
oscillation.The schematic/layout has been finalised and PCB's are on their way! I
can finally start working on the casing design.
