Here’s a cool crowdfunding campaign that somehow escaped the Hackaday Tip Line. It’s a remote control SpaceShipOne and White Knight. SpaceShipOne is a ducted fan that has the high-drag feathering mechanism, while White Knight is a glider. Very cool, and something we haven’t really seen in the scratchbuilding world.
[Sink] has a Makerbot Digitizer – the Makerbot 3D scanner – and a lot of time on his hands. He printed something, scanned it, printed that scan… you get the picture. It’s a project called Transcription Error.
Keurig has admitted they were wrong to force DRM on consumers for their pod coffee cups.
The Apple ][, The Commodore 64, and the Spectrum. The three kings. Apple will never license their name for retro computer hardware, and there will never be another computer sold under the Commodore label. The Spectrum, though… The Sinclair ZX Spectrum Vega is a direct-to-TV console in the vein of [Jeri Ellisworth]’s C64 joystick doohickey.
Infinity mirrors are simple enough to make; they’re just one mirror, some LEDs, and another piece of glass. How about a 3D infinity mirror? They look really, really cool.
Here’s the six-day notice for some cool events: Hamvention in Dayton, OH. [Greg Charvat] will be there, and [Robert] is offering cold drinks to anyone who mentions Hackaday. If anyone feels like scavenging for me, here’s a thread I created on the Vintage Computer Forum. Bay Area Maker Faire is next weekend. Most of the rest of the Hackaday crew will be there because we have a meetup on Saturday night
Keurig, the manufacturer of a single-serve coffee brewing system, has a very wide following amongst coffee drinkers. Their K-cup (pre-packaged coffee grounds with a coffee filter, all in a plastic container) is an interesting concept and makes brewing a single cup of coffee much more efficient over making a whole pot. Their newer line of coffee makers, the Keurig 2.0, has some interesting (and annoying) security features though, which [Kate Gray] has found an interesting and simple way around.
The DRM security in these coffee makers is intended to keep third-party “cups” from being used in the Keurig. It can recognize an authentic Keurig cup, and can stop the operation of the coffee pot if a knockoff is placed in the machine. We can only assume that this is because Keurig makes a heap of cash by selling its canisters of coffee. One simple solution was already covered a few days ago by taping an authentic lid to the machine. This one doesn’t require any authentic pods but just removes one wire from a wiring harness inside of the case.
There are other ways around the security on these devices, but when [Kate Gray] actually investigated, she found the security decidedly lacking. With something this simple, one can only speculate how much Keurig has really invested in making sure users don’t use third-party cups of coffee in their machines, but it also brings up the classic question of who really owns hardware if we can’t use it in the way we want, rather than the way the manufacturer wants.
You can read more about the project on its Reddit page. Thanks to [MyOwnDemon] for the tip!
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.

[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?
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.

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.

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.
