ChipWhisperer Hits Kickstarter

Even the most well designed crypto algorithms can be broken if someone is smart enough to connect an oscilloscope to a processor. Over the last 15 years or so, an entire domain of embedded security has cropped up around the techniques of power and side channel analysis. The tools are expensive and rare, but [Colin O’Flynn] and the ChipWhisperer are here to bring a new era of hardware security to the masses.

The ChipWhisperer was the second place winner of last year’s Hackaday Prize. It’s an interesting domain of security research, and something that was previously extremely expensive to study. If you’re looking for a general overview of what the ChipWhisperer does, you might want to check out when we bumped into [Colin] at DEFCON last year.

While the original goal of the ChipWhisperer was to bring the cost of the tools required for power and side channel analysis down to something a hackerspace or researcher could afford, this was still too expensive for a Kickstarter campaign. To that end, [Colin] designed the ChipWhisperer Lite, a cut-down version, but still something that does most of what the original could do.

There are two parts to the ChipWhisperer Lite – the main section contains a big microcontroller, a big FPGA, and a high gain, low noise amplifier. This is the core of the ChipWhisperer, and it’s where all the power analysis happens. The other part is a target board containing an XMega microcontroller. This is where you’ll run all your encryption algorithms, and where you’ll find out if they can be broken by power analysis. The main board and target board are held together by a break-away connection, so if you want to run a power analysis on another board, just snap the ChipWhisperer in half.

[Colin] is offering up a ChipWhisperer Lite for around $200 USD – far, far less than what these tools cost just a year ago. We’re looking forward to a successful campaign and all the neat findings people with this board will find.

Ask Hackaday: Bringing Your Design to Market

While many of us have made and documented our open source projects, not many of us have tried to sell our design to the masses. [Scott] developed, marketed, and “bootstrapped” a cool looking MIDI controller. Now, before you get your jumpers in a bunch – the project is completely open source. [Scott] documented the entire process of not only the design, but the trials and tribulations of bringing it to market as well. Calculating costs, FCC testing and the many other challenges of bringing a consumer electronics device to market are all detailed in his blog. Join me while we look at the highs and lows of his interesting and eventually worthwhile journey.

Putting yourself into a game where orders are in the tens of thousands, with hundreds of thousands of dollars changing hands is not easy when you’re just a guy with an idea and a soldering iron. [Scott] was up for the challenge, however. He quickly realized that much of the margin is spent on advertising and to cover risk. On his last order, some of the paint was chipping off. He had to fix the paint and repackage everything – all at his cost.

He also talks about the learning process of product design along the way. His original idea was to make a volume controller, but couldn’t sell a single one. He was forced to redesign the software into the MIDI controller as it exists today. He tried to launch a Kickstarter, but was rejected. This turned out to be a good thing, however, because he would have wound up kickstarting a product that didn’t work.

For advertising, he relied on Google and made some extremely detailed tutorials for his product. Many of them can be used for other MIDI controllers, and often come up in Google searches. Smart. Very smart.

Be sure to check out the video below, where [Scott] gets into some capacitive touch design theory, and talks about how not to cut your final product in half while on the CNC.

Have any of you ever tried to mass produce and sell one of your designs? Let us know in the comments!

Hackaday Links: The Last One Of 2014

The guy behind the Microslice, a tiny Arduino-controlled laser cutter, has a new Kickstarter out. It’s called the Multibox PC, and it’s exactly what you need if you want to turn a Raspi, Banana Pi, HummingBoard, or Odroid U3 into an all-in-one desktop. 14″ 1366 x 768 LCD, and speakers turns dev boards into a respectable little Linux box.

If you’re learning to design schematics and lay out PCBs, you should really, really think about using KiCAD. It’s the future. However, Eagle is still popular and has many more tutorials. Here’s another. [Mushfiq] put together a series of tutorials for creating a library, designing a schematic, and doing the layout.

Another kickstarter wristwatch. But wait, this thing has a circular display. That’s really cool. It’s a 1.4″ 220×220 pixel, 262k color display. No, the display doesn’t use a polar coordinate system.

[Jari] wrote a digital logic simulator, Atanua, started selling licenses, and figured out it wasn’t worth developing on his own anymore. As promised, Atanua is now open source. If you want to look at the finances behind Atanua, here you go.

In 1970, you didn’t have a lot of options when it came to memory. One of the best options was Intel’s 1405 shift register – 512 bits of storage. Yes, shift registers as memory. [Ken Shirriff] got his hands on a memory board from a Datapoint 2200 terminal. Each of the display boards had 32 of these shift registers. Here’s what they look like on the inside

There’s a lot of talk about North Korean hackers, and a quick review of the yearly WordPress stats for Hackaday puts a tear in our eye. This year, there were fifty-four views from the Democratic People’s Republic of Korea. That’s just great. It’s awesome to see the hacker ethos make it to far-flung lands and through highly restricted firewalls. There’s still a long road ahead of us, though, and we’ll redouble our efforts on bringing the hacker mindset to Tuvalu and Saint Helena in the year 2015.

Christmas Lights And Ships In A Bottle

Thanksgiving was last week, and Christmas has been invading department stores for two or three months now, and that can only mean one thing: it’s time to kill a tree, set it up in your living room, and put a few hundred watts of lights on it. All those lights, though; it’s as if Christmas lights were specifically invented as fodder for standup comedians for two months out of the year. Why can’t someone invent wireless Christmas lights?

We don’t know if it’s been invented, but here’s a Kickstarter campaign that’s selling that same idea. It’s called Aura, and it’s exactly what it says on the tin: wireless Christmas lights, controllable with a smartphone. If it works, it’s a brilliant idea.

Phoenard, A Prototyping Gadget

The Hackaday Prize party wasn’t just about the five finalists; actually, there were more THP entries in attendance – All Yarns Are Beautiful, OpenExposer, M.A.R.S., a 3D scanner, and a few more that I’m forgetting – than actual finalists. In addition, a number of people brought projects that had never seen the light of day, like [Ralf] and [Pamungkas]’ Phoenard.

Phoenard is a Kickstarter project the guys launched at the prize party, something they could attend as a little side trip after manning the ‘maker’ part of the Atmel booth at Electronica. They’ve come up with a tiny handheld device that can only be described as a ‘gadget’. It has a touchscreen, a battery, an MegaAVR, a few connectors, and not much else. What makes this project cool is how they’re running their applications. A bootloader sits on the AVR, but all the applications – everything from a GSM phone to an MP3 player – lives on a microSD card.

The Phoenard guys have come up with a few expansion modules for Bluetooth LE, GSM, GPS, and all the usual cool modules. Plugging one of these modules into the back of the device adds capability, and if that isn’t enough, there’s an old 30-pin iPhone connector on the bottom ready to accept a prototyping board.

Video of these guys below.

Tesla Truck Wants to Bring The Makerspace To The Children

With so many budget cuts, many public schools find themselves having to cut “unnecessary” programs such as shop, art, and music classes. They simply can’t afford to keep those things running and also teach other important concepts like math, language, and history. The obvious side effect is that kids don’t have a safe place to be creative and learn to make things with their hands.

Luckily, the maker movement has been rapidly growing over the last few years with makerspaces popping up all over the globe. These places are picking up the slack left behind by the budget cuts that hurt our public schools. But while makerspaces are getting more and more common, they still don’t exist everywhere. Even in those places lucky enough to have a makerspace, not everyone is aware that they exist and not everyone can afford to be a full-time member. This is where Tesla Truck comes in.

The Tesla Truck’s mission statement is “to provide a cutting-edge, mobile, hands-on STEM lab, where students, teachers, and makers can teach, learn, collaborate, create, and innovate.” It’s a noble cause for sure, but how do they plan to do this? This group intends to outfit a truck with the kinds of tools every maker dreams of. These would include a 3D printer, laser cutter, CNC plasma cutter, mill and lathe, electronics bench, and more.

Obviously just having a bunch of high-end tools is not going to cut it. Someone is going to have to teach people how to properly use these tools. The group behind the Tesla Truck is made up of educators, engineers, and published researches who have been doing this kind of thing for a while now. This group has been packing up their own personal tools into their hatchbacks and setting up shop in school classrooms around New York City, only to have to break down at the end of the day and bring them all home again. Together with the students, this group has built things like robots, quadcopters, and water purifiers. The Tesla Truck will give them the ability to reach more people much more easily.

The Tesla Truck is looking to raise a total of $62,804.01 to make their dream a reality. They have raised more than half of that outside of crowd funding. They’ve now turned to Indiegogo to raise the last $24,300. They have ten days left and they are almost halfway to their goal. You can watch their campaign video below to get a better feel for what they are all about. Continue reading “Tesla Truck Wants to Bring The Makerspace To The Children”

Carvey, the CNC Machine for Everyone

Over the past few years, [Bart Dring] has contributed immensely to the homebrew CNC machine scene, with the creation of MakerSlide linear rail, the buildlog.net open source laser cutters and CNC machines, and a host of other builds that have brought the power of digital fabrication to garages and workshops the world over. After a year of work, he, along with Inventables, is releasing Carvey, the CNC machine for everyone else.

Carvey is heavily inspired by Inventables other CNC machine, the Shapeoko, but built to be the Makerbot to the Shapeoko’s RepRap, without all the baggage that goes along with that analogy, of course. The machine has a 300W spindle capable of cutting wood, plastic, foam, carbon fiber, and linoleum, as well as aluminum and brass. There are a few interesting features like a color-coded bit system, and this time the machine has an enclosure for containing MDF dust.

CiebwEA13yxYp576g_7HRNUx06KmzO3QEqGCLfs4kRoCAD programs might be a little too foreboding for someone just getting into the world of CNC, so Inventables has created their own design program called Easel. It’s a web app that allows you to design all your parts for the Carvey and send them all to the machine without worrying about speeds, feeds and all the other intimidating machinist terminology. You can, of course, output GCode from Easel, so those of us with slightly more complex toolchains can still use the Carvey.

Inventables is Kickstarting their production, with the non-early bird Carveys going for $2400. That’s a bit cheaper than some extremely similar machines we’ve seen on Kickstarter before.
