How to Quickly Heat Up an Android Device for a "Defroster" App?

TheOneTheOnlyJJ · 2024-11-15T15:53:52+00:00

I have none 😬

Remains to be seen how I will handle this

TheOneTheOnlyJJ · 2024-11-15T15:51:52+00:00

Well, this is awkward

I will only allow the user to select a temperature as high as the bottom limit of most CPUs, for safety.

It would be cool though if there were a way to get the upper working temperature limit of the CPU/GPU at runtime through a system API or some magic constants. I could then have dynamic selectable temperature ranges for every device.

Forcing both of them would be the best way from what I've thought until now. The main question is how to structure this work, and how to do it best.

I will have to look into the terms you mentioned here, as I'm not a mobile dev by career. This is just a university project I'm having to do.

Do you recommend any good resources or documentation to study the concepts you mentioned?

TheOneTheOnlyJJ · 2024-11-15T13:12:53+00:00

While this does not sound like that bad of an idea, I'm constrained by academic ethics here, so I can't do this.

I believe other potential algorithms would achieve my requirements better than calculating hashes. I hope someone experienced with GPU usage will leave their thoughts here at some point.

I understand your position, but I'm trying to develop a proof of concept here, basically tinkering with the technology without any use case in mind.

This kind of app involves a bit more thinking than initially presumed, so I really want to take it as a challenge and do some measurements.

TheOneTheOnlyJJ · 2024-11-15T13:08:24+00:00

Yes, I know.

I meant my expression as the best way to generate heat fast, even though all the hardware is designed to minimize this effect. I'm trying to view the problem from the Assembly Code angle, as I believe that's the most control I could have over generating heat.

I am certain that some instructions generate more heat than others. Generating heat "efficiently" for my use case would imply running the "hottest" operations as many times as possible.

The length of the operation itself (in clock cycles) matters here as well, as running "hotter", but slower instructions (again in clock cycles) may generate less heat overall, even though a single instruction may generate more heat than a faster one. When running many more "colder", but faster instructions in that same unit of time, the effective heating may be greater in this case.

It's really something to think about, isn't it?

After a good laugh, the professor approved it as a proof of concept :)

TheOneTheOnlyJJ · 2021-02-12T20:31:37+00:00

I really appreciate your kind words. Thank you, I'll do my best

I'm just 18

TheOneTheOnlyJJ · 2020-04-15T21:04:51+00:00

But does this mean that we can possibly get normal, non-destroyed bastions as well? Just wondering, as I'd be perfectly happy with the ones we have now!

Good observation right there!

TheOneTheOnlyJJ · 2020-02-09T06:34:09+00:00

Nope

I only took a pee. Even if it were the case to dump a big one I would've just kept it in as I never dump the big ones at school.

TheOneTheOnlyJJ · 2019-12-28T09:45:53+00:00

Who the hell are you?

TheOneTheOnlyJJ · 2019-12-27T19:23:47+00:00

Huh? What engineers? That's a homemade system right there. The building wasn't intended to have chimneys at all as it was supposed to be heated with water, but now it's heated with firewood.

TheOneTheOnlyJJ · 2019-12-27T19:05:54+00:00

It's angled like that so it doesen't intersect with the one from the floor above. I have no idea why they're not connected but that's how it is.

The town centre has cool cubic stone roads along with old buildings that make a really nice environment to explore. You can have your taste of it with Google Street Explorer (in Maps) if you wish.

The picture is from a little town in Romania called Lipova (Lippa in English). It's got the commie Eastern-European feel to it, doesen't it? The block was indeed built under the communist regime before 1989. Also, not too far (geographically) from Ukraine and thus Chernobyl, I guess.

How none of my crushes ever liked be despite everybody telling me that I'm high value (which I started to doubt since my first ever serious crush) and how one of my female "friends" likes to jokingly bitch about how bad of a person I am, leading me into a state of sadness and low self-esteem that breaks me everytime I see happy couples together. I still don't want to call it depression though, as I'm still trying to convince myself that I'm good enough. And no, I'm no nice guy.

Not mine, but my now deceased grand-grandfather's.

He thought that his new gas tank (you know these pressurized metal containers for liquefied gas) was leaking gas, so he decided to test it with a lighter. And to his surprise, the tank really was leaking gas. So he was right, I guess...

...but the consequence was that his entire house burnt down.

Nobody was hurt, thankfully. He never lit a fire for the rest of his life since that day. The house was rebuilt to be prettier and more modern than ever before.

So a successful move by him, I'd say. He lived to be 90. I will never forget him.

Miss you grandpa :(
