Boosting PC with explosions

[Vatablous]

So I have an old PC that weighs about 8.5 KG (18.7 Lbs) and I was wondering how much gunpowder I would need to boost it into the air when its dropped?

Drop PC onto gunpowder and get gunpowder to boost pc back into the air with impressive force. How much gunpowder is needed?

 

Thanks guys!

When I read the title it took me a while to get it, but I think you will get formula for that on Wikipedia, Google it

thats not how any of this works...

I smashed a hammer onto gunpowder yesterday and it worked. Now I'm turning the hammer into a computer.

assuming gunpowder ignites from force, not a spark(which it doesnt), the amount of force required to ignite it, would far exceed the kinetic force created by an object falling on it. unless it created a spark when it landed

 

it wont work

You're saying gunpowder doesn't ignite from force?

correct.

correct.

How do guns work then? And how was it that I slam a metal object into the gunpowder which causes it to ignite?

guns work because the rounds have a primer, which is what the hammer strikes.

and you slammed a metal object onto it, presumebly while it was on the ground, creating a spark which ignited it.

Ok, back to the original idea then, If the computer managed to gain enough momentum and somehow sparked with the ground, how much and what sort of gunpowder would be needed to launch it back into the air?

Doubt anyone's ever had to calculate this first. Maybe you should just buy a bunch and then tell us how much it took. Doesn't sound like a bad way to spend an afternoon, plus if it doesn't work you have a bunch of gunpowder to play with, which if were to guess I'd say it would be pretty hard to get the gunpowder to ignite. Even if dropping the computer could create a spark, the amount of gunpowder required to create that kind of force would most likely insulate the PC from making contact with the ground.

Currently, the gunpowder I'm using is out of caps from a cap gun (google cap gun caps) and just one circle of those mangled up a hard drive's spinning disk pretty well. 

 

(unrelated but Petr how did you get your i7 to 5.1 GHz? I cant get mine to 4.8?)

assuming ideal conditions, you would use black powder, not gunpowder. gunpowder doesnt actually explode, its conflagurates(burns really fast) because its low density, great for propelling things(like bullets) but not great to create a force wave that would be needed to lift the computer.

 

black powder however, is more suited to your needs, as it releases 3 million joules of energy per kilogram.

you'd have to calculate how much force would be needed to move the computer would would be Force=mass x gravity

force =  8.5KG x 10m/s²  which is about 85 Netwon meters of force.

 

so if my math is right, you would need roughly .02 grams of black powder to move the computer. probably a bit more to actually lift it. but not too much more to avoid blowing it up entirely

Good math. That really doesn't seem like much powder and from a quick search, it seems fairly easy to get.

its not a lot, and honestly doesnt seem like it would be enough.

its actually really easy to make at home too. i wont go into it, but everything you need can be bought at home depot.

 

one issue you're going to run into, is that just a pile of it may just put a hole in the case and not be dispersed enough to create lift. so you would need a bit more and spread out enough. but not too much, so you dont just blow it the fuck up

[Vatablous]

Honestly, this was just a theoretical thread but it seems really easy to do. Thanks for the help!

I've got it 5.1 @1.38v with an AVX offset of 3. What is keeping you at 4.8? Thermals or stability?

I have never overclocked before. I also only built this system a few months ago. It's stability. I have tried a few times before but my computer always ends up crashing.

[PETRGangKing]

Try using an AVX offset. If the highest you can get it stable at is 4.8, you take whichever clock you're going for, subtract 48, and put your avx offset at that number. So say you're going for 5.0 ghz, you would set your CPU core at 50 and your avx offset at 2.  50-48= 2

Huh, that's interesting. I really don't know anything about Overclocking. Do I do this in bios?

[PETRGangKing]

Yes. It's also worth noting that overclock ability varies from chip to chip. While one 7700k might hit 5.1, another one might top out at 4.9

Ah thanks. Do you have any other tips for overclocking? Where to find this stuff in bios?

[PETRGangKing]

Not really, with unlocked processors it's nowhere near as difficult to overclock as it used to be. Depending on your motherboard, the option for avx offset should be right by where you change the core ratio. Unless you are running on a Skylake motherboard, then it won't have that option as it was introduced with the z270 boards

[PETRGangKing]

Just make sure you have a good cooling solution, if you haven't delidded it, 7700k can get HOT
