Hedberg Is A Bionic Hand Made From A Single Keurig

August 12, 2016 by 11 Comments

Developing into a modern hacker and tinkerer requires a lot of things: electronics study, programming knowledge, and patience (among many other things). But, the most important quality a hacker can have is curiosity. The desire to see how things work is what drives most budding hackers towards the dismantling of family appliances and electronic gadgets.

Many end up scavenging parts from the things around the house for their first projects. But, with money and more ambitious builds comes the need to purchase parts off the shelf. There is, however, something to be said for the ingenuity that comes with building something solely with scavenged parts, and that’s what [Evan Booth] decided to do, in a spectacular fashion.

Dead Simple Hack Allows For “Rebel” Keurig K-Cups

December 10, 2014 by 141 Comments

If you haven’t actually used a Keurig coffee machine, then you’ve probably at least seen one. They are supposed to make brewing coffee simple. You just take one of the Keurig “k-cups” and place it into the machine. The machine will punch a hole in the foil top and run the water through the k-cup. Your flavored beverage of choice comes out the other side. It’s a simple idea, run by a more complex machine. A machine that is complicated enough to have a security vulnerability.

Unfortunately newer versions of these machines have a sort of DRM, or lockout chip. In order to prevent unofficial k-cups from being manufactured and sold, the Keurig machines have a way to detect which cups are legitimate and which are counterfeit. It appears as though the machine identifies the lid specifically as being genuine.

It turns out this “lockout” technology is very simple to defeat. All one needs to do is cut the lid off of a legitimate Keurig k-cup and place it on top of your counterfeit cup. The system will read the real lid and allow you to brew to your heart’s content. A more convenient solution involves cutting off just the small portion of the lid that contains the Keurig logo. This then gets taped directly to the Keurig machine itself. This way you can still easily replace the cups without having to fuss with the extra lid every time.

It’s a simple hack, but it’s interesting to see that even coffee machines are being sold with limiting technology these days. This is the kind of stuff we would have joked about five or ten years ago. Yet here we are, with a coffee machine security vulnerability. Check out the video demonstration below.

Wireless Keurig Hack!

coffeemaker

[Kolumkilli] loves his Keurig coffee maker, as it makes him an excellent cup of coffee, but he doesn’t like waiting for it to brew. So he set out to make it wirelessly controlled via his computer… with the press of a button, he can have his coffee ready and waiting for him when he gets up.

After carefully dismantling his Keurig, he set to locating the main buttons on the PCB, and proceeded to wire in relays in parallel to the ones he wanted to control. Throw in a Moteino and add the notification LEDs as inputs as well and now he can control and monitor almost all the coffee maker’s functions via a web browser at his desk. Now if only he could remember to put a new coffee cup in…

There’s a great writeup on the forum post, so if you want to see a more detailed build log, check it out! And if you’re looking to add even more functionality to your Keurig, why not run a waterline to it?

Keurig Hack Now Automatically Fills The Water Reservoir

June 3, 2013 by 26 Comments

keurig-automatic-water-fill

This hack makes your Keurig experience fully automatic. For those that aren’t familiar with the hardware: this type of coffee maker includes a water reservoir. Coffee is brewed One cup at a time by drawing from that water, quickly heating it, then forcing it through disposable pods containing coffee grounds and a filter. This takes the user-friendly design one step further by automatically keeping the water full.

This goes beyond the last water reservoir hack we saw. That one routed a water line to the machine, but included a manually operated valve. [Eod_punk] added a solenoid valve and level sensor in this project. The level sensor is submerged in the tank and is monitored by a Basic Stamp microcontroller. When the level is low the BS1 drives the solenoid via a transistor, letting the water flow. This is all shown in the video below.

Keurig Hack Runs A Water Supply Line To Your Coffee Maker

April 25, 2013 by 57 Comments

We were skeptical about Keurig machines when we first heard about them. Although we still scoff at the added waste of throwing away a plastic container of used grounds for each cup of coffee made, we tried one at the in-laws and it does brew a great cup of Joe. One of the draws of the machine is that it does it pretty much automatically as long as you fill it with water first. [Joseph Collins] is even taking the work out of that by adding a water supply line to his Keurig.

His coffee maker sits right next to the fridge, which has its own water supply. So one day he thought, why not run a line to the coffee maker as well? As far as plumbing projects go it’s very simple. He pulled out the refrigerator and added a T-fitting to split the water supply line. From there he ran an extension next to the coffee maker that terminates with a valve being pointed to by the arrow in the lower left. The plastic supply line leaving the valve passes through a rubber grommet in the lid of the water reservoir pointed to by the other arrow.

[Joseph] figures the whole project came in at under $30 and shows how he did it in the clip after the break.

Aquarium Water Exchanger Built From Keurig Parts

March 21, 2012 by 22 Comments

We keep seeing commercials for those Keurig coffee makers that use a plastic pod of grounds to brew just one cup of coffee. We’re pretty sure this is a fad, and absolutely sure that the extra packaging created by brewing with this method is a waste. But to each his own. [Danman1453] has two of the devices. One he bought, the other is a warranty replacement. He decided to scrap the malfunctioning unit and see if he could put it to good use. What he ended up with is the aquarium pumping system you see above.

It is conceived as tidier way to swap out the water in the fish tank. He had been using tubing to siphon the water, but found he almost always made a mess. This system uses an air pump to prime the water pump by pressurizing the tank which forces water into the lines. Once the water pump is primed he switches over to that for the rest of the work. He used an old metal tool box as an enclosure, using the cover to mount the push-buttons which route power to various components when pressed. Many of the parts were transplants from the coffee maker, but even if you sourced all of the components new this wouldn’t cost too much to put together.

Securing Your Keurig With RFID

keurig-hacking

[Andrew Robinson] and his co-workers are lucky enough to have a Keurig coffee maker in their office, though they have a hard time keeping track of who owes what to the community coffee fund. Since K-Cups are more expensive than bulk coffee, [Andrew] decided that they needed a better way to log everyone’s drinking habits in order to know who needs to cough up the most cash at the end of the month.

He started by tearing down the Keurig B40, making note of the various PCBs inside while identifying the best way to go about hacking the device. The coffee maker is controlled by a PIC, and rather than try to re-engineer things from the bottom up, he left the core of the machine intact and focused on the control panel instead.

He disconnected all of the unit’s buttons from the control board, routing them through an Arduino before reconnecting them to the machine. This essentially rendered the machine inoperable unless triggered by the Arduino, giving [Andrew] control over the brewing process. He wired in an RFID reader from SparkFun, then got busy coding his security/inventory system. Now, when someone wants coffee, they merely need to swipe their office access card over the machine, which enables the use of its control panel.

As you can see in the video below the system seems to work well. If we were to offer some constructive criticism, we would suggest ditching the laptop and rolling the RFID reading/verification into the Arduino instead – other than that, we think it’s great.
