Could you link me to a 555 control circuit? I'm not exactly sure how that would work. I know the 555 is a timer chip, but I have never used one.
I did order a CN3722 board for $9 off ebay. It will be here in 2-5 weeks, haha. I am a little concerned that I will burn it up working at it's max output. We will see. I will explore other options in the mean time.
I was able to find some inexpensive ($5) 6A dc-dc step up converters for the output. They even have undervoltage protection which is a great thing. I was thinking I would use two of them.
