+This folder contains photos of assembled working prototypes (version 0.1) of three O-ESD candidates
+1) Flyback based O-ESD,
+2) Push-pull based O-ESD and
+3) Audio-amplifier based O-ESD. 
+
+The prototypes are made modular so that multiple transistors can be used in flyback/push-pull, all available audio amplifiers, trafos and relays can be interchanged, all produced shapers and cascades can be used, virtually any configuration for power supply can be tested, as well as arbitrary connections between the microcontroller and all O-ESD functional parts. The details for schematics and used components can be found in data from the previous stages of development.
