For the swatch book exchange 2017, i continue to explore the vinegar etching technic to make my circuit but this time instead of trying to make a precise circuit some parts are made by hand, making a unique version of each pcb. To express the idea, i’ve made a simple attiny capacitive circuit which trigger a led. After etching the circuit and solder the component, i apply a layer of silicone to secure the connections.
