Version 0.2: Berlin Wall Distortion Pedal – Circuit Layout (2017)
Important sites, border crossings and roads of West-Berlin 1961-1989. Routes between markers/components are mapped to work as a circuit for a distortion pedal (there are bridges were the road cross). Red routes are on the face of the circuit and gray routes under the circuit (they follow the U-Bahn routes / excluding the 9v in). Components are located on important landmarks and diodes are located border crossings (diodes will be connected to switches outside the board, from were they return to the ground). The wall is ground and connects outside of the circuit. Off board components include A10k, A100k potentiometers, 22uF capacitor/4.7k resistor/led, audio in/out jacks, a rotary switch (2 pole, 3 positions for signal in to the airport caps), a 3PDT footswitch. etc.
Any tips on improving the design welcome! I’ll redesign the layout to fit a 7x10cm circuit board and etch it.
