Tell us about yourself!
I don't know what regulator you are using but it looks like a step down or buck regulator. That's why you need a voltage above 5v for it to regulate. Look for a step up or boost regulator. Those bring a low voltage up by reducing the amp output. I don't know what kind of power your product can produce burr I'm sure it can work
Awesome project to upcycle all those pvc and wood extras of other projects
Good idea.Could i ask where your shed is located. Like exactly. Full address. To... you know... congratulate you....Just kidding. Seriously now. Good idea
Not wanting to be mean but instructables is a web for tutorials on how to do stuff. Not how to buy stuff. That's why.
Wait!!! What???? You are feeding ac power of 110v or 220v through an arduino????Don't suggest I'll repeat. Nobody do that please!!!!!!Don't want to sound mean man but do some research first and don't suggest people to feed dangerous ac power to ecposed pcb like an arduino wich will blow

You can try painting It black and leaving It under the sun a bit for free heated water
