Good news from CadSoft this week. They didn’t miss all the complaints about their decision to use a Node Lock License for EAGLE 7. This had meant that users of the popular PCB design software would be limit on how many machines they could use the software with a license. They have removed License Management from the package (and all the citizens rejoiced).

We’re tripping over the growing pile of hardware that boast the “next-big-thing” in getting devices onto a network. That’s not a complaint at all. This time around it’s a cell chip, the U-blox SARA-U260, which can connect to 3G on the AT&T network and is just 16x26mm. They call it world’s smallest but we have no idea if that’s true or not. Anyone have a source and/or pricing for these? [Thanks Austin]

This guy loves his Nixie tube. How much? To the extent that he built up a hardware and software interface that behaves much like a pet. It’s voice activated, and the infectious delight of [Glasslinger’s] video demo is in itself worth watching. [Thanks Morris]

Making this Magnetic Stripe Reader work as a USB device is really nothing more than adding a serial-to-USB converter. The journey to find the way to add the converter makes for a fun read though.

We know from watching Breaking Bad that you can kill power to a building by shorting the power lines outside with a huge bouquet of mylar balloons. This installation is a twist on the idea. Connecting one mylar balloon to a Van de Graaff generator and floating it next to another results in an oscillating repel-discharge-repel cycle. [Thanks filnt via NPR]

Kyocera is vastly expanding their product lineup with the Shop Sink 3530. The perfect addition to your copiers, fax machines, and laser printers.

About a year and a half ago and with objections from the editorial staff, we did a Top 10 hacking fails in movies and TV post. The number one fail is, “Stupid crime shows like NCIS, CSI, and Bones.” A new show on CBS just topped this list. It’s named Scorpion, and wow. Dropping a Cat5 cable from an airplane doing an almost-touch-and-go because something is wrong with the computers in the tower. Four million adults age 18-49 watched this.

thing[Derek] found something that really looks like the Hackaday logo in a spacer of some kind. It’s been sitting on his shelf for a few months, and is only now sending it in. He picked it up in a pile of scrap metal, and he (and we) really have no idea what this thing is. Any guesses?

[Sheldon] has a teardown of a vintage voltage and current standard. Just look at those hand drawn traces on a single sided board. Beautiful.

[Art] has another, ‘what is this thing’. He has two of them, and he’s pretty sure it’s some sort of differential, but other than that he’s got nothing. The only real clue is that [Art] lives near a harbor on the N. Cali coast. Maybe from a navigation system, or a governor from a weird diesel?

So you have a Kinect sitting on a shelf somewhere. That’s fine, we completely understand that. Here’s something: freeze yourself in carbonite. Yeah, it turns out having a depth sensor is exactly what you need to make a carbonite copy of yourself.

Obviously the best way to show you’ve pwned a piece of hardware is to run Doom on it. This time around it’s not just a hardware hack but a security hack. [Michael Jordan] demonstrates a network vulnerability on a Canon printer by making it run Doom. [Thanks to all who sent this tip to us]

Fans of the photo-resist method of PCB etching will appreciate this Bromograph built from an old all-in-one-printer. When gutted, the body of the printer makes a nice enclosure for four UV Lamps. The treated copper clad goes face-down on the scanner glass with the printed transparency between the two. [Michele’s] early testing shows really great results.

[Tom] sent in a link to this video biography of the rLab hackerspace. It shows off the space and its members but also tells the story of a tight-knit community. We enjoyed hearing that almost everything in the space is salvaged and repaired; a great way to acquire equipment on a tight budget while also building the skills of the members.

The bulbs in projectors can be quite expensive to replace. This hack adds an RC filter to the bulb and claims to greatly extend its life. Does this really work and why isn’t it built into the projector?

[Steve Maher] built a GRBL board that is the same form-factor as a DB25 connector housing. It’s basically an Arduino derivative that includes a USB connection, a separate jack for STOP and CYCLE START switches. If you’re not familiar, GRBL is an open source project that lets your drive parallel-port-based hardware with a machine that doesn’t have a parallel port.

Finally, have you heard of the ZofzPCB program before? It’s a way to visualize your gerber files in order to perform a final sanity check before sending your deign off for fabrication. [Thanks Boldport]

Photonicinduction is back! The Brit famous for not setting his attic on fire has built a 20,000 Watt power supply. It connects directly to England’s national grid with huge connectors. Impeccable fabrication and triple servo controlled variacs, and apparently this will be used for making a lot of hydrogen and oxygen through electrolysis of water.

In case you missed it, there’s a group buy for Flir’s Lepton thermal imaging module. Here’s the breakout board.

Need to solder something away from an outlet, and all you have is a disposable lighter? There’s a fix for that.

A Raspberry Pi case designed to be compatible with Lego. Now we need a hat/shield for NXT connectors.

Need another channel in your RC remote? Here’s this. It uses the gyro gain channel on a receiver. If someone wants to figure out how this works, wee do have a rather cool project hosting site.


Here’s something impossibly cool: The Macintosh PowerBop. It’s a Powerbook 170 with the floppy drive replaced with the radio in a cordless phone. It was part of France’s BiBop network, and you could buy private base stations for use at home. It is technically possible to use the radio as a wireless link to a modem, but [Pierre] couldn’t get PPP or a sufficiently ancient browser working. Plus ten points for taking it to an Apple store, and another twenty for trying to connect to our retro edition.

Chicken Lips. [Fran] and our very own [Bil Herd] are hanging out a bunch and recalling [Bil]’s time at Commodore. For this little featurette, [Bil] brought out his very own Commodore LCD. There are three of those in the world. Also included: tales of vertical integration, flipping bits with photons, and 80s era ERC.

Like Adventure Time? Make your own BMO! It’s a little more expressive than the Adafruit version we saw earlier due to the Nokia LCD. It’s got audio playback too so it can talk to football.

A few years ago, [Matt] made a meat smoker with a PID controller and an SSR. Now the same controller is being used as a sous vide. PID controllers: the most useful kitchen gadget ever.

[Josh] keeps his server in a rack, and lacking a proper cable management solution, this means his rack is a mess. He adapted some Dell wire management arms to his system, using a PCI card bracket to attach the arm to the computer.

[Dr. Dampfpunk] has a lot of glowey things on his Youtube channel

Another [Josh] built a 3D tracking display for an IMU. It takes data off an IMU, sends it over Bluetooth, and displays the orientation of the device on a computer screen. This device also has a microphone and changes the visualization in response to noises.

Remember the pile of failure in a bowl of fraud that is the Scribble pen? Their second crowdfunding campaign was shut down. Don’t worry; they’re still seeking private investment, so there’s still a chance of thousands of people getting swindled. We have to give a shout-out to Tilt, Scribble’s second crowdfunding platform. Tilt has been far more forthcoming with information than Kickstarter ever has with any crowdfunding campaign.

Adafruit did another Circuit Playground, this time concerning frequency. If you’re reading this, no, it’s probably not for you, which is great because it’s not meant to be. If you have some kids, though, it’s great. Not-muppet robots and oscilloscopes. Just great.

The Hack42 space in Arnhem, Neterhlands recently got an offer: clean out a basement filled with old computer equipment, and it’s yours. Everything in the haul had to fit through an 80cm square door, and there are some very heavy, very rare pieces of equipment here. It’ll be a great (and massive) addition to their museum. There’s a few pics from the cleanout here and here.

[Mike] has been working on a project to convert gerber files into SVGs and it’s great.

[Carl] did a roundup of all the currently available software defined radios available. It’s more than just the RTL-SDR, HackRF, and BladeRF, and there’s also a list of modifications and ones targeted explicitly to the ham crowd.

This is a Facebook video, but it is pretty cool. It’s a DIY well pump made in Mexico. A few rubber disks made out of an old inner tube, a bit of PVC pipe, and a string is all you need to bring water to ground level.

What can you do with a cellphone equipped with a thermal imaging camera? Steal PIN codes, of course. Cue the rest of the blogosphere sensationalizing this to kingdom come. Oh, what’s that? Only Gizmodo took the bait?

About a year ago, we saw a pretty cool board made by [Derek] to listen in on the CAN bus in his Mazda 3. Now it’s a Kickstarter, and a pretty good one at that.

Your connectors will never be this cool. This is a teardown of a mind bogglingly expensive cable assembly, and this thing is amazing. Modular connectors, machined copper shields, machined plastic stress relief, and entire PCBs dedicated to two caps. Does anyone know what this mated to and what the list price was?

Remember those ‘cocktail’ arcade cabinets? The Ikea Lack table has existed for years, so why not make one into an arcade table? Raspberry Pi with RetroPie as the brains,  and an ancient 4:3 monitor as the display.

Old Unixes! Running on PDPs, Novas, and IBMs! Thanks to Simh, you can emulate these old machines. [Matt] put up a guide to getting Simh running on a Pi that includes running Unix V5 on an emulated PDP-11.

Ever wanted to run your own telecom? The folks at Toorcamp did just that, 50 lines, 10,000 feet of 1-pair, and 1,500 feet of 2-pair. There’s a facebook album of all the pics.

Remember last week when Sparkfun said they shipped 2000 Microviews without a bootloader? Make interviewed [Marcus Schappi], the guy behind the MicroView. There’s also a tutorial on how to fix the issue.

Barbie needs an exorcism.

Remember the [Lord Vetinari] clock from way back when? It’s a clock that ticks 86400 times a day, but the interval between each second is just slightly random and enough to drive people insane. Here’s a kit on Tindie that makes it pretty easy to build a Ventinari clock, or a variety of other clocks that are sufficiently weird. There’s also a martian clock that’s 39 minutes and 36 seconds longer than normal, perfect for the folks at JPL.
