(about powering mb with 6vdc)
Recently I read a post elsewhere about using solar panels to power a usb port to charge various devices. I have an assortment of panels, ranging from tiny 1.x volt panels about 1 in. squared to a full sized, 6/12v 53w "home/commercial" grade panel.
I'm trying to use them (live in a really sunny state) to save a little and put the solar energy to good use, but don't have the funds to "go big", and actually make a deep cycle battery "proper" system. I read an article recently about using the mintyboost as a vessel between the panel and "device". My main concern is this..
The article used a 6v panel, and led mention that you could alternatively use a cluster of small panels (such as the 1in ones from those solar night lights you put along your path, driveway, etc.). When I started digging around though, I find warnings and notices all over saying NOT to ever use more than 5v with the mintyboost. The article I linked (also on this forum) even mentions an elaborate schematic someone was working on to allow the 6v source, though gets lost in a debate over battery vs. capacitors..
Can someone give me a decisive "this will or will not work" with a 6v source? Some research seemed to indicate I need a "Buck converter", not "Boost convertor", but when I looked up buck converters, they were all these large mammoth devices, where people are taking far more excessive amounts of voltage and desiring low voltages.. Didn't seem to really fit what I need, but by the same token, there are a ton of posts/comments here and on other articles in regard to using a mintyboost NEVER to exceed 5v.
As a follow up item. Whether I provide an exact 4.8-5v or less (or more, like the 6v I am mentioning above), is there a "easy" way to get 1000ma out of this instead of the 500ma? I ask because while I see the HTC Evo listed (one of the many things I plan on using this for), the Evo actually prefers to draw 1000ma, and in fact, on car chargers rated at 500ma causes the battery/phone to overheat as well as heats up (excessively) the car charger. The stock supply ac adapter in fact is rated at 1000ma. I'd like to replicate that, if possible, but know next to nothing to make it happen. I can solder and build for days though, if I have something to follow, rofl :)
Appreciate all the time and assistance on this, thanks :)
