Nevermind

AA laddas are rewrapped panasonic eneloops

Damn it, I was nearby Ikea last week

I don't see 2450mAh eneloops though

@Millwood what Julian said, go for the Ikea batteries

the white ones have more capacity

brown ones are more useful in stuff like TV remotes

white is right 👌

and brown ones arent rechargeable iirc

they are @Julian

Yeah, even chink ones are more expensive so I'll get those when I'm in ikea

based ikea batteries

Ikea sells non-rechargeable batteries too but those are silver+yellow

I replaced pretty much every regular battery in my house with rechargeables from Ikea

most of the light bulbs are LED

very eco friendly household

How often do you have to recharge the ikea batteries?

depends on what you use them for and how often you use them

I've tried searching alibaba and can't seem to find a fitness tracker that has oxygen+bp+hr that also has an open source app to use with it. I am mainly needing it for my grandpa so that we can be alerted to changes in his health.

oxygen?

oxygen readings, the miband which I know works with gadgetbridge only does HR

How the hell would you measure that woth a watch

Yeah, you'd need blood samples for oxygen

a pulse oximeter

it uses a flashing light and some sort of sensor to read the oxygen levels.

not perfect but still it's "good enough" as a rough guideline.

Will never work on a wrist

You need something on both sides

And as thin as a finger

what the fuck gearbest just messaged me on facebook

this which is on amazon which is just a rebrand of various chinese versions says it works.

Thats blood pressure, what the hell are you on about

basically something like that, since apparently they can do it. No idea how it works but verified purchasers say it was on the money.

reviewer with verified purchase states it does oxygen somehow.

According to what metric?

Also the link is broken

some random reviewer on amazon. I just need something that's close enough as my grandpa hates wearing a blood pressure cuff.

Do you mean oxegen or blood pressure
