Connect up to 16 satellites to one receiver with AVR DiSEqC switch

DiSEqC-Switch is widely used in individual satellite systems to connect up to 16 satellites to one receiver using cascading method. This switch uses other cheap DiSEqC-Switches ver1.0 with four satelite heads each or simply connects directly to satelite heads and this way acts as simple switch.

Schematic diagram is based upon standard DiSEqC-schematic solutions except connections between the Attiny13 and the output switches. This solution allows to reduce number of transistors. PCB is available in P-CAD format. Decoding algorithm of incoming DiSEqC messages are explained here. Also you can check out Testing Device for DiSEqC-Switches that is uses 1.0 or 11 protocols .
