Can someone explain to me how a Schmitt trigger works like I'm a 5 year old? Thank you

Hi, I'm building a solar panel project that may use the charge battery and so on. As solar output is not consistent, I have a capacitor array to store charge before deliver it to the end devices. However if the solar output power is lower than the end devices(example charging phone) power load, it will probably on and off since the solar output is not enough. I would like to use by capacitor array to reduce the on and off rate by design a Schmitt trigger or perhaps it a flip flop circuit. For example if my Solar panel max voltage is 12v and my device using 5v thru a voltage regulator that need min of 6v. So I would like to design a circuit to do this 1) When capacitor array discharge to 6v, terminate the circuit to regulator. 2) Wait for the solar panel to charge the capacitor up to 12V 3) Upon reach 12 V, allow the current to pass thru regulator again. Repeat step 1 I tried so search Schmitt trigger circuit but I cannot find the suitable one as most Schmitt trigger is with a Vref and signal input. Since my voltage input(capacitor charging and solar panel) is variable, I do not have Vref. I still believe it can be achieved, perhaps my mind stuck at one concept only

I have been told that a Schmitt trigger can flash an LED, just like a 555 timer can, only the circuit is simpler. I haven't been able to find an example of this online, however.

I'm curious about where instructables members purchase their electroincs parts. I've played around with electronics since high school, but I've always been in an environment where parts are "free" (aka paid for by others). Now that I'm branching out on my own, I'd like to know the best place to buy parts. I did a quick comparison of Jameco and Mouser on my blog. http://www.thelumberlab.com/2011/catalog-fight-jameco-vs-mouser I'd greatly appreciate it if you all could share your thoughts on this. Thanks so much.
