then use a microcontroler with a voltage comparator and a switching power supply

Well isn't everyone using a 2a charger anyway?

or you know, put like 4.2v continuously and pray

Also are they acctually damaged by charging at ~100mAh?

Other than it taking forever

The word is that low charge rates kill the anode and cathodes

no, only if you surpass the limit

Low and high are bad for different reasons

High is obvious

Low causes corrosion and decreased capacity

yeha, but getting more than 100 cycles from the cheap batteries is really hard

I just replace them...

Yup you're doing it right

Otoh

The guys buying 13000mAh banks don't know that stuff

I'm really fearful of housefires

I doubt they realize what they're signing up for

But this goes banks, not just chink and again why would you charge with a normal USB port and not your 2a charger?

you get 3000-3500mAh from a 18650

you're fooling yourself if you don't think the average person is using their computer to charge

Some guy is NZ is buying a big bank for $35

Scrolll up

usb 2.0 is like 100mAh

It's probably too late to tell him stahp

if you speak the protocol you can get 500mAh maximum

per specs

but needs negotiation

Yeap. For single cell 18650 its fine, as would a Lopo at around even 3000mAh

But charging a 10Ah battery on 500mA is silly

Lipo*

Or even 2A

you can use those cheap RC battery charger for planes and shit

they have everything

Yeah I think you're preaching to the choir

Like I said

I don't think normies and other /csg/'ers know what they're going in for

I use a bench power supply an a skyrcmeme

Those nitecore things aren't great

same, I used to tape the leads to a bench power supply with electrical tape when i was broke

Why would you wait 24h to charge with a pv

Pc

Anyone on g should be using a charger

People don't know electricity dude

They just think "oh it's usb"

Go out and meet people once in a while. You'll be pleasantly depressed

The 90iq normies sure but I don't think g does this

http://i.imgur.com/zcGLniR.png

fuck you chinky

do you think g is not full of 90iq normies?

there are generals spoonfeeding them on how to build a pc

I think you overestimate the austimal level of /g/

No it's full of 90iq weebs uwu

Less than almost anywhere

@Tendril I stand corrected

Sadly I deal a lot with normies irl

>I'm above it all because I have an anime avatar

This makes you worse than normies

The omni-psyche turbo wizard 40+ year olds who REALLY know their shit lurk BBS forums.

Not /g/ or /tech/.

eevblog maybe

I like Dave

There are some smart people on /g/, I won't deny that, but not many.

/g/ is visited by wizards once in a while

I knew that one tripfag Marisa for like, 5 years on and off

They're REALLY sharp in ganoo/loonicks and C

But that's about it uwu

compsci is more compatible with channers than hard science or engineering /bait

I dunno.

I spent a year doing hardware fault-finding and the process you have to go through every time is autismal as fuck.

no doubt

My boss was one of those turbo wizards though, so that helped.

It's frustrating debugging bad connections

Especially when they're faulty by (bad) design

are you one of the fuckers that add a shitload of 0 ohm resistors unmarked so its imposible to reverse engineer?

Turns out that EEs aren't good mechanical engineers

I once had to diagnose a desktop which kept powering off for temp reasons

and eventually we just ruled that the temp sensor itself was fucking knackered

Which is really frustrating because the only way you can rule that is to stick your fingers in the heatsink and note that it's fucking cold even when the machine is 'overheating'

Imagine trying to do that for something like a guidance system

Horrifying.

And then convincing them "well, it's the motherboard's fault"

And you're shipping the built-in-test for the next contractor in the chain

can you change a temp sensor on a motherboard? , I thought most sensors are etched in silicon

And you can't do shit because contracts are already signed and you can't do a complete redesign because your little firm may be bankrupted

Yeah, sounds like it'd have you really backed into a corner.

software is comfy

You can always ship a patch

exceptvin embedded design...

Hardware is frightening and nightmarish in comparison

So you'd have to forgive if us hw guys are more autist

We literally have to have whole designs in our heads running in pseudo simulation casually

Which leads to cool a-ha moments

Fortunately, I've only been stuck with fault-finding and repairs.

But it's generally shitty

Either way, you do have to be a giant fucking autist with hardware, because it's like you said.

You have to be 100% with what you do.

Yeah repairing and hobby stuff is fun

I'd hate the fault finding thing

Well you need a better testing framework and harness
