How to safely charge and discharge a supercap

How to safely charge and discharge a supercap 5 boards for about $22 in about 7 days https://www.pcbway.com In this video we look at one way of safely charging and discharging a supercapacitor. We use a suitable resistor to limit the current and cutoff the power as the cap reaches our desired level of charge. There are other ways to achieve this, but this is a simple method available to anyone with a DC power supply. Capacitor calculator: http://mustcalculate.com/electronics/...
