I want to make a capacitive dropper and i have a 203 film capacitor that i will use for it. What will be the voltage drop on it. I tried to use an online calculator but it doesn’t work.
Hi everyone,
I'm working on a little DIY lamp project with a capacitive switch.
The kit consists of a breadboard with some components, a battery and its charging PCB, and a 20cm-long electric wire that leads to the aluminium foil used as capacitive sensor.
