Coffeematic PC – A coffee maker computer that pumps hot coffee to the CPU

[jfengel]

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.

[swiftcoder]

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

[mulmen]

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.

[umanwizard]

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.

[reactordev]

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.

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

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

[pitched]

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.

[nosioptar]

Could use an old P4 Celeron as the secondary heater.

[tecleandor]

Let's do cold brew then...

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.

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

SGI was ahead of the game: http://mycollins.net/sgicoffee.png

[Joel_Mckay]

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

[yupyupyups]

>The coffee is too cold.

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

[Lio]

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!

[bitcrshr]

No worries of HTTP 418 here.

[bongodongobob]

It better support RFC 2324.

https://en.m.wikipedia.org/wiki/Hyper_Text_Coffee_Pot_Contro...

[throwmeaway222]

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

[zeta0134]

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.

[dougdude3339]

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

[bluelightning2k]

100% Java compatible

[layer8]

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

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.

[9front]

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

[ghm2180]

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]

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

[dabumere]

This just made me smile

[dougdude3339]

Means a lot - thank you :)

[iammrpayments]

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

[dougdude3339]

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.

[ZiiS]

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

[parlortricks]

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

[dougdude3339]

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

[reboot81]

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

[bawana]

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

[happycube]

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

[BizarroLand]

This is the right kind of absurd for a Friday afternoon

[imchillyb]

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.”

[nojs]

Finally the Java logo makes sense.

[inciampati]

Now do mayonaise.

[xandrius]

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

[MangoToupe]

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

[m463]

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

[dougdude3339]

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

[dredmorbius]

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

Its objectives lie elsewhere.

[ViscountPenguin]

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