I have a supercapcitor to power some of my small projects. The only problem is that the voltage drops gradually, unlike a lithium ion battery, in which the voltage is mostly stable throughout. My boost converter that I am using to boost the voltage up to 5 volts, stops working with an input voltage below 1 volt, and it is a 2.5 volt super capacitor, so the power source dies almost twice as fast, because i can only use a little more than half the power in the cap. My question was, How would I boost the voltage of my super capacitor up to the usable 1 volt, if it is lower than that? Can I use some sort of Joule Thief with my Super Capacitor? Is their some sort of other method I have not considered?
