Wow, What A Really Great Idea & Using Our Friend The Sun, I Like It!! You Did A Beautiful Job On The Way You Laid Out The Solar Cells, That Coulda Been A Headache!! There's Something I Thought I'd Share With You; Before You Spray The Plasti Dip On The Back Of The Solar Cell Discs, There Are Several Companies That Make A Paint-On Type Electric Insulation [One Calls It "Liquid Electric Tape"] And It Has A Brush Attached To The Lid [Like Pipe Dope Cans Have] You Might Want To Put Some Of That Stuff On A Day Or So Before The PlastiDip Stuff & You Can Also Paint It Over Circuit Boards Also If I Remember Correctly, Ya Might Wanna Check That Out First Though!! I Dont Know If It Might Help Ya Any, Just Wanted To Share A Thought!! Another Idea Is You Could Approach A Company That Makes The Umbrellas About Including Your Product During The Manufacturing Of The Umbrellas; That Could Help Solve The Problem You Had In Opening & Closing Them!! Great Job & Good Luck On The Success Of Your Product!!

It was interesting and clearly demonstrated at least part of the fallacy of the perpetual motion.

Hi,Sure, send me the specs and I'll see if I can come up with something.Cheers,Mike
Ok, it looks too complicated for me. Would you consider selling me one of these? If so, I would look at the specs of my small pump and you could build it for those specs.
I am looking for a way to power a small water pump for a small fountain. Not a fancy large fountain, just one that trickles for the birds. The problem is that all of the times I try to use the small solar panels that come with those other pumps, they must be directly in the sun, I mean if it is off by even the slightest angle they wont work. Do you think this would work for such a thing?
The battery from the link below may work for you. Based on the description, it charges a few iPad models(2A) and has two USB outputs. You'd have to regulate your solar panel output current to 1A though.https://www.adafruit.com/product/1566

Thank you for your kind words! I actually did apply for a design patent a while ago. They are so slow! I just had to get out of my lab into the world!
Thanks! I've been experimenting with some different charging circuits. I'm looking for one that can charge the lipo and, at the same time, deliver power to mulitiple USB ports. Most of the charging circuits I've found either can't do both at once or can't deliver more than 2A. Any suggestions?
Great idea! I'd suggest adding a small lipo battery with a charger circuit to solve your issue with power consumption!
Thanks for your suggestion. I considered something like that but I was worried it might block too much of the umbrella's surface color, logos, etc.
This projet provides 5V and how much current????
So sorry if I don't understand this but I am 13 and I need to know what this robot does.
