Kind of surprised it doesn't have better battery life...

Incidentally, you’ll want to avoid draining the Beepy’s battery too deeply if you can help it — according to the schematics (and confirmed on my actual hardware) SQFMI have used a 10K resistor on the “programming” pin of the TP4054 charging IC. That sets the chip’s charge rate to a measly 100 mA, which means a full recharge of the battery would take somewhere in the neighborhood of 20 hours. It’s hard to believe this was intentional, and may be addressed on a later hardware revision.

Yeah, this is a really cool idea, but they need to flush it out a little more. analogue audio and faster charging would make it a lot more appealing

Bigger battery might not be a bad idea either, but I say that about everything.

Has me wondering if ever we'll reach a state where we just have battery packs like backpacks that we just wear as a daily habit, like putting a shirt on. It'll charge up overnight, then go in a sleeve that's machine washable (otherwise ew), and have a half dozen or so PD USB-C ports that we just tap into for phones, smart watches, laptops, etc

People definitely care battery chargers around and I've seen some that are integrated into backpacks already so it's kind of already started. I heard the chargeable backpacks are kinda meh though and you're pretty much better off just sticking some batteries in your pack.

I've had a backpack for years that has usb plugs for a battery pack sewn into it. It's been a thing for like a decade.

Longer I think

20 hours

What the fuck. Yes it is a cool product, THAT however needs to be fixed before they launch this thing. 20 hours? Imagine trying to implement this for some kind of project and having to wait basically a whole goddamn day for it to charge lmao

In order to keep costs down the Pi is based on some pretty ancient hardware. DDR2 uses so much power no matter what, it's not like modern stuff that uses nothing idle.

[–] _haha_oh_wow_ 1 points 1 year ago

Yeah, could put a beefier battery in this thing though.
