Hi I have an Idea for something. I wanna make a low-power wearable project. I wanna attach an rgb tricolor led to a attiny85 and have it run off a super capacitor. Also I'm going to attach a motion switch to wake up the attiny85. The problem is that I'm having a hard time finding an example schematic for a simple capacitor charger. Most are rated for a much higher voltage or are controlled by a manual switch.
If I remember correctly if you connect a capacitor directly to power (without over-volting it), It will eventually stop drawing power. Because it's technically an open circuit (on the inside of the cap).
My first question is: Can someone help me create a charging circuit? My second question is: Can I make it wireless with QI charging?
