This is the right kind of absurd for a Friday afternoon

This just made me smile

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

m463•8h 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

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

ViscountPenguin•6h ago

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

shakna•6h ago

Tell that to the gaggiuino crowd.

Avicebron•5h ago

That's forbidden jutsu.

sillywalk•4h 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•5h ago

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

Its objectives lie elsewhere.

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•8h ago

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

fadesibert•7h ago

And of course, peculation means misappropriating or embezzling funds. Again, given crypto (and certain notorious crypto exchanges), even more appropriate.

Dilettante_•1h ago

FWIW, I would not have known 'peculating' was a real word with a meaning if GP hadn't explained.

Joel_Mckay•6h ago

Never, the French Press is superior in every regard. lol =3

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

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.

jfengel•8h 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•7h 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•7h 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.

reactordev•7h 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•6h ago

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

mulmen•6h 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.

swiftcoder•18m 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

It better support RFC 2324.

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

parlortricks•7h ago

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

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

ghm2180•5h 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.

bitcrshr•4h ago

No worries of HTTP 418 here.

Finally the Java logo makes sense.

happycube•3h ago

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

iammrpayments•2h ago

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•1h ago

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

Lio•1h 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.
