standard D-cell has 4 ish Amphours (from top of my head iirc) at 1.5v (or 12Wh if you will ?

I could check again, but I think it's closer to 15 for alkaline, and 4 for rechargeables.

yeah might be that im remembering zinc-carb ones as herpderp

but even alkalines are at 20ish Wh

figuring out how much playroom you have here after the panel draws what ever it wants (full bright colorblend continous animation case ?)

It's been a few months since I looked last, but I remember mathing out that the TV would run for maybe 6 hours with no other power draw, and I was thinking about half that time if I really maxed out an SBC.

so getting that what 15ish Ahs out of it

It was going to be black-and-white TV at whatever shit resolution 😂

Look, in any case, I know for a fact that a Raspberry Pi 4 can pull just over 7 Watts at full chooch, and I have no idea whatsoever what the Rock64 draws since no one wants to fucking talk about it, if they already own one.

look at spec sheets?

5v 3A suggested supply

>>> ROCK64 require +5V 3A power supply with Type H 3.5mm OD/1.35mm ID barrel ‘coaxial’ type plug. The power supply available in PINE64 store.

I don't recall the power for just the board; just the suggested power like Tervy says.

That's totally inaccurate to the board's actual use, since it takes into account maximum draw from all of the available USB ports, too.

Of course the Pi 4 doesn't burn fifteen fucking watts at full use.

sure but youl be using that to calculate

not optimal scenario

so you get free safety margins if nothing else

Sure, I just wish someone would measure the actual draw. I've only ever found quotes for the suggested draw from the spec sheet.

XU4 has recommended 5V4A and (5v6A when usb3 HDD)

Actual draw tho <:pepeturt:499291994649133067> someday

Hello, I'm a retard. I got everything I needed for a diy solar panel, decided against buying tabbing wire because lol it's just a nickel strip. Tried doing it with 0.5mm copper wire, shit was fuck, too thick, pain in the ass to tin the wire, too stiff, cells broke. Ok, wanted to do it quick, bought a nickel strip locally. Of course it was too hard to do proper research and it's a plain nickel strip, not a tinned one. Too wide, too, so I had to cut it with scissors. Managed to tab 4 cells out of 36 needed before ragequitting and ordering proper tabbing wire from China

so yeah time to get that amp-meter and strap it to that TV

to check the thing

I just wanted a fucking solar panel for summer

Now it's gonna be ready for winter

be cheap get cheap

:D

Yeah

Since it was relatively simple to tin the nickel wire, I think I won't have many problems with tabbing cells with proper wire

So now I'm eyeing bigger cells

Not like the sun stops existing in the winter.

Can get a surprising amount of energy from solar panels in the winter.

muh solar power

oh look

the boomer fears renewable energy

ghostwriter.

@androidcrawler im all for renewable energy but allocating huge plots of land just for solar panels is a massive waste of space

To be fair how renewable are solar panals compared to nuclear

the efficiency is increasing
