This is the right kind of absurd for a Friday afternoon

dabumere• 12 months ago

This just made me smile

dougdude33399• 12 months ago

Means a lot - thank you :)

xandrius• 12 months ago

Absolutely cool project but unfortunately percolating coffee is nowhere near the best way to brew a good cup of coffee.

m463• 12 months ago

Should probably run cpu benchmarks while slowing water cooling pump + pressurizing cooling system above 9bar and expressing water through carefully tamped specially ground coffee and drip into cup.

or just have a large reservoir, severely overcool the cpu and cold-brew the coffee

MangoToupe2• 12 months ago

This must be a matter of taste because I strongly disagree.

ViscountPenguin• 12 months ago

Good luck hooking up an espresso machine to a PC though.

shakna• 12 months ago

Tell that to the gaggiuino crowd.

sillywalk• 12 months ago

It's not a PC, but SGI made an espresso machine inside an Indigo case as a marketing gag. The "Espressigo".

I assume that they're referring to something other than espresso if they're trying to get the best cup.

dredmorbius• 12 months ago

Very little about this project screams "best" or "fully optimised".

Its objectives lie elsewhere.

dougdude33399• 12 months ago

Glad you like the project. I might have special taste in coffee, this stuff is pretty good, but honestly I like instant too...

Groxx3• 12 months ago

I'm glad someone is still building what needs to be built <3

v0.2a needs to mine crypto to pay for its own coffee beans while peculating the coffee. =3

MostlyStable• 12 months ago

I assume you meant "percolating", but you very nearly spelled "speculating", which, given the crypto, seems more appropriate.

angled• 12 months ago

Then tokenise the mined crypto. The tokens can be represented by coffee beans. The beans are now magically valuable!

Digitally enhanced coffee as fungible tokens. “Decaf” for short. What could go wrong?

Excellent find I have never heard of - thank you for sharing

zeta0134• 12 months ago

This is the very best kind of silly project. :) I'm pleased to learn that the coffee is an effective (... sortof) heatsink and not merely part of the case.

dougdude33399• 12 months ago

Thank you - I wonder, if in some microscopic way, the coffee is caffeinating the CPU too.

jfengel• 12 months ago

Why not rig it the other way: pump water past the CPU, then through your coffee grounds?

It probably wouldn't be great for your CPU, because the temperature required to properly brew coffee is hotter than you really want for your CPU. But maybe get the water to 80C, and a secondary heater after that.

umanwizard• 12 months ago

I'm not expert in CPU water cooling but I'd guess the CPU would have to be way over 100C in order to get the water to 80C quickly.

macNchz• 12 months ago

You could recirculate water past the CPU via an insulated storage carafe. This would create a fun and exciting gamble wherein you might receive a freshly brewed pot of coffee OR your computer might turn itself off just before the water is hot enough to brew with, and the time it would take would be based on how hard you worked the PC.

nottorp• 12 months ago

Modern Intel can help.

_Algernon_• 12 months ago

Add a heat exchanger.

reactordev• 12 months ago

This, except when it comes time to actually brew, it goes to a 5.25” slot to heat up, then you can determine the best delivery mechanism for your build. Shot/Kup, drip, pour over, just don’t build a french press PC.

And have a reservoir large enough to replenish the closed loop circuit when you press the button.

reaperducer• 12 months ago

The CD ROM drive should open so you can insert a paper cup and then the coffee dispenses into it.

mulmen• 12 months ago

Use a heat pump to keep the CPU (and GPU as a secondary heat source) at a lower temperature then heat the coffee water with a secondary heat exchanger. Then you can control the temperature of both cooling loops independently.

swiftcoder3• 12 months ago

Maybe one wants a mini heat pump between the CPU and the coffee. 50º C is plenty for a heat pump to very efficiently push the temperature on the other side to 98º C or so

matheusmoreira3• 12 months ago

Can this concept be extended to the home in general? Why not pump heat out of computer components and into a general hot water tank for home use? I wonder if anyone's tried it.

pitched• 12 months ago

80C is about the lowest you would want to use but can definitely get you a good cup of coffee. It will come out a bit lighter but using a finer grind might offset that.

tecleandor• 12 months ago

Let's do cold brew then...

nosioptar• 12 months ago

Could use an old P4 Celeron as the secondary heater.

omh• 12 months ago

Many years ago we used a hot P4 to heat mulled wine.

https://imgur.com/a/mulled-wine-pc-WW1pW

It could get to 60°C which is a bit low for coffee but was great for mulled wine

dougdude33399• 12 months ago

Incredible - thank you for sharing this.

bongodongobob• 12 months ago

It better support RFC 2324.

throwmeaway222• 12 months ago

It does, unfortunately there is a bug as every request is returning a 418.

parlortricks• 12 months ago

Time for you to use my 1080ti with Furmark too cook some eggs and bacon to go with the coffee.

dougdude33399• 12 months ago

Damn that's a good idea... orienting the graphics card horizontally would've made a little frying pan.

Tread carefully. This is how the Borg started. “Your caffeinated and medicated existence will be added to our own, resistance is futile… pass the creamer.”

It should use the logo: https://mybcagroup.blogspot.com/2016/07/what-is-hot-java-hot...

9front• 12 months ago

He's using "Linux Mint" for OS. Should have used "Coffee Linux" instead.

ghm2180• 12 months ago

A key with haptic feedback that when pressed runs the CPU/GPU and as water heats up the button lets you know. Calibrate feedback to temperature and ease off the button when the water is done.

bialpio• 12 months ago

Was a reference to https://xkcd.com/1172/ intentional here?

bitcrshr• 12 months ago

No worries of HTTP 418 here.

nojs• 12 months ago

Finally the Java logo makes sense.

happycube• 12 months ago

Someday this should be upgraded to an 8th or 9th gen core i7. ;)

I don’t know what the pipes are made of, but doesn’t look like something I’d like to heat and run my water through it before drinking it

ZiiS• 12 months ago

Usually PVC not dissimilar to your home plumbing; but yes at temperate it can leach.

dougdude33399• 12 months ago

The tubing and pumps are food safe, however, the radiators and cooling block are not. It's a special tasting cup of coffee best consumed in moderation.

Lio• 12 months ago

I’d like to see this project extended with AI to work out what drink the user really wants before dispensing a drink almost, but not entirely, unlike tea.

Share and enjoy!

yupyupyups• 12 months ago

The coffee is too cold.

Don't worry, I'll run an Electron app.

inciampati• 12 months ago

Now do mayonaise.

I'd just like to interject for a moment. What you're referring to as GE Coffeemattic PC, is in fact, GNU/GE Coffeemattic PC, or as I've recently taken to calling it, GNU plus GE coffeemattic. GE Coffeemattic is not a PC unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full PC as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which pumps hot java today is often called "GE Coffeematic PC", and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a GE Coffeemattic exists, and these people are using it, but it is just a part of the system they use. GE Coffeematic is the coffee kernel: the program in the system that allocates the machine's caffeinated resources to the other the user's physical space. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Coffeemattic is normally used in combination with the GNU operating system: the whole system is basically GNU with Coffeemattic added, or GNU/GE Coffeemattic. All the so-called "GE Coffeemattic PC" distributions are really distributions of GNU/GE Coffeemattic PC.

tap->coffeemaker->radiator->pc->cup. ?

really stupid arrangement. slurry from the coffeemaker clogging your rad and cooling block, not to mention corrosion

better would be RO water -> pc -> coffemaker no rad needed

I need to make one of my own, when Im done fixing up an old bike for my fish.

GPUs and alcohol distillation always seemed like a match:

I used to manage a scientific supercluster, heavily laden with GPUs. We were constantly consuming about 60kW of power. These GPUs were happy to run at 85C, which from other interests I knew to be the temperature where alcohol distillation occurred. I always wanted to install a heat exchanger and distill fuel with all of the waste heat.
