Hay /g/, I'm interested, can you build a computer that runs on Double A batteries?

Pic related, sparked interest.
>>
A non-rechargable AA Battery typically has 4~ wh of power.

A typical laptop battery has around 60 wh

Assuming you wire them properly to end up with the input voltage a laptop requires, you can potentially power a laptop for a few hours with 15 AA batteries.

There is a reason they have rechargeable batteries.

Interesting. So around how many batteries would be needed to power this setup for 5 hours:

Full load is 300~ watts

(300 * 5) / 4 = 375 AA batteries
A good estimate for an AA batteries weight is 25 grams, 25 * 375 = 9.375 kg , or 21 pounds going off memory.

That's amazing. Jesus christ I want to see a person with a labtop containing a huge-ass battery full of batteries.

I'm going shopping tomorrow. I've been looking for something to do with my old rig. I'll get a backpack and all the batteries my credit limit will allow and make a really autistic heads up display.
>>
>>51415621
make sure you mix series and parallel correctly to get the desired voltage.
>>
Duracell or bust, OP. Energizer Bunny is a liar and a scoundrel.

>>51414647
The capacity of alkaline batteries is dependant on the discharge rate. Spend the extra money and get the "for high powered devices" lithium type, if you're actually going through with this stupid idea.

meanwhile in a parallel universe where thinkpads don't exist, a /g/entleman walks into his uni class with his "laptop"

ESP8266 can be programmed with LUA and it has Wifi for <$3, runs on 2 AA batteries
>>
First thing that came to mind. Runs on 2 AA batteries. There's also that asia-exclusive thinkpad that runs on 6 AA batteries.
>>
A Pi could easily with a step up regulator.
Same as a phone.
A small windows tablet perhaps?
>>
>>51415643
Easiest but a bit dangerous would be to just connect them all in series to get 100v+ so with 100 1.5vs in series youd get 150v and provided your psu doesnt have active pfc or anything of the sorts it should run just fine off of dc allowing you to just plug it in.

I've powered a raspberry pi with a 4AA pack before.

This TRS-80 Model 100 ran on 4 AA batteries, I believe it was the first 'Notebook' computer.
>>
Buy a raspberry pi clone with 5v2a power input, get a 3.5mm barrel to USB adapter and find a USB charger that supports AA batteries.
>>
>>51414647
Yes, you could get a Raspberry PI and power it from 4 AA batteries.
Not a good idea, but possible, it would be a much more better deal to just get a $3 chinese powerbank and attach it to the PI
>>
>>51416383
I don't know if it was truly the first of the sort, rather it was probably the first that was actually usable for anything. Others had things like shitty keyboards, or 20x2 displays.
>>
>>51414647
I have an old 2009 laptop that I power with 3x 12v 7ah SLA battery's in series and a homemade buck converter set to 19v, works flawlessly. But I only do it because I don't have the AC adapter and the laptop doesn't require a 3 pin "smart" charger.
