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

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

Earlier quoted context omitted.

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

It's not a PC, but SGI made an espresso machine inside an Indigo case as a marketing gag. The "Espressigo". https://commons.wikimedia.org/wiki/Category:SGI_Espressigo https://old.reddit.com/r/SiliconGraphics/comments/1eh9puu/sg...

Excellent find - I haven't heard of this one. The marketing gag approach reminds me of the Zotac Mekspresso build by Ali “THE CRE8OR” Abbas. https://thecre8or.de/mekspresso.htm

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.

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.

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.

Add a heat exchanger.

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

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.
