How did you go about reverse engineering it?

I'd be curious to read about that, myself.

Pretty simple, actually!! This model (B31) contains:

- 12VDC air pump to push water from tank into coffee pod

- 10K thermistor, stuck in the tank

- 1400 Watt heating element

I wired all three to the Arduino through a transistor for the pump, a resistor divider to use analogRead() and calculate temperature, and a mechanical relay.

The Arduino uses 4 buttons: heating element toggle, temperature up/down, and pump engage. I didn't bother with the water sense non-sense Keurig uses (to know if water is in the tank or reservoir), so it pretty much checks temperature and if it is low engages the relay. When it's done I then hit the button to dump the water through the coffee (so it's not as automated as Keurig, but better than buying a new one). Code is here:

The thing was a pain to disassemble too. It's one of those "oooooooohhhh that's how it's put together" products where you have completely destroyed the plastic tabs before you see the one magic screw holding it together.

Yeah, I'm gradually coming around to an RMS-y way of thinking – having to tape small bits of an old K-cup onto my Keurig 2.0 is DRM bullshit that I have no room for in my life. Fuck them. Some people will use the new Keurig and its DRMed cups because it provides them with enough value. I will completely bypass this nonsense and make a DRM-free cup of dirt cheap coffee that stimulates my senses, as outlined in another…

Can I recommend an Aeropress? It's only a little more work than a Keurig (about the same as a french press), and makes some of the best coffee I've ever had. It's also $25, and has no moving parts or electrical components.

I don't even drink coffee (bitter to me), but those who like coffee at my former employer where skipping the company provided machine and coffee packets and using one of those.

Seems lest wasteful.

For a single cup of coffee, I'm partial to the AeroPress. It takes a bit more work, but the strange looks I get from my coworkers is worth it.

The Aeropress makes the best coffee I've ever had at home. I've tried moka pots, regular coffee brewers and French presses. The Aeropress is better than all of those hands down.

Have you tried a Chemex or other pour over?

I add powdered caffeine to my morning Soylent. (really.)

I'd recommend anyone trying this to be cautious with the amount you add.

Primarily because caffeine is extremely bitter and adding too much will ruin it. I tried to put like 500mg of caffeine powder in my cereal once and it was utterly disgusting. I got about 4 spoonfuls in before I couldn't take it anymore.

On the subject of leaching dangerous chemicals into coffee, moka pots are definitely bad idea. The coffee absolutely picks up a lot of aluminum.

I love my Aeropress, but an arguably even simpler option is something like the Hario V60 (http://www.amazon.com/Hario-V60/dp/B000P4D5HG/). $19, and no plastic if that matters to you. I think the filters probably cost you a bit more than the Aeropress.

IMHO you should have several different coffee brewing methods at your disposal :-)

Call me paranoid but I refuse to drink hot liquids out of plastic containers of any kind. A glass french press is the way to go.

As someone who owns (and regularly uses) an aeropress, may I ask why? Simply out of of curiosity, not out of disagreement.

Leaching chemicals. Here's an article I found after a quick google search, http://myplasticfreelife.com/2011/04/bpa-free-does-not-mean-...

It doesn't mention heat, but I presume leaching increases with heat.

I have owned two Nespresso machines. They were both great for about 8 months. Then no matter how much I 'cleansed' them they made terrible tasting coffee. You can never get the insides completely clean. I suspect the Keurig has a similar problem. I'm now back to my ceramic filter cone (one-time $20 cost) and the coffee has never tasted better.

Ammonia is the way to clean a coffee maker.
