The First Evil Maid-Proof Computer

August 9, 2016 by Brian Benchoff 157 Comments

It doesn’t matter how many bits your password has, how proven your encryption is, or how many TrueCrypt volumes are on your computer. If someone wants data off your device, they can get it if they have physical access to your device. This is the ‘evil maid’ security scenario, named after hotel maids on the payroll of a three-letter agency. If someone has physical access to a laptop – even for an hour or two – the data on that laptop can be considered compromised. Until now, there has been no counter to this Evil Maid scenario, and for good reason. Preventing access to data even when it is in the possession of an Evil Maid is a very, very hard problem.

Today, Design Shift has released ORWL (as in George Orwell), the first computer designed with physical security in mind. This tiny disc of a computer is designed to defeat an Evil Maid through some very clever engineering on top of encryption tools we already use.

The Onion Omega2: The Latest Router Dev Board

July 21, 2016 by Brian Benchoff 42 Comments

A few years ago, the best way to put a device or project online was by hacking a router. With an inconspicuous Linksys WRT54G held onto a project with baling wire, anything can connect to the Internet. A lot has changed in a few years, and now those routers are development boards themselves. The latest of these is the Onion Omega2, a follow-up crowdfunding campaign to the very popular original Omega. Now, this tiny dev board is faster, more capable, and now it’s giving the Raspberry Pi Zero a run for its money.

The original Onion Omega was released last year with specs you would expect from an Internet of Things development board designed upon a chip for a cheap router. The original Onion used an Atheros AR9331 SOC running at 400 MHZ, had 64MB of RAM and 16MB of storage – enough to run a lightweight Linux distro – and also included USB, 802.11b/g/n, and a handful of GPIOs and a single UART. The Omega2 is a vast improvement over the original Omega, featuring a CPU that is 45% faster. The upgraded version of the Omega sports twice as much RAM, twice as much storage, and a MicroSD slot. This enables some Linux distros with a little more oomph behind them, and of course the SD card allows for local storage.

The original Onion Omega was funded through a crowdfunding campaign, with a single Onion Omega and dock available for a pledge of $19. Taking a lesson from the C.H.I.P. and the Pi Zero, the team at Onion have slashed the price. The Omega2 is only five dollars. If you want more RAM, storage, and an SD card socket, that price goes up to $9 USD. That’s amazing, and just goes to show how far hardware designed to service the Internet of Things has come in just a few short years.

Foster A Robot, Explore Your Home Planet

June 24, 2016 by Dan Maloney 9 Comments

The robots we’ve sent to explore other worlds in our stead are impressive feats of engineering. But stuck at the bottom of our gravity well as we are, they are fantastically expensive ventures that are out of reach of the DIY community. There’s still plenty to explore right in your own backyard, though, and this robot needs your help to explore planet Earth.

The project is called RoboSpatium, and it’s the brainchild of [Norbert Heinz]. The idea is a little like HitchBot except it will be sent from host to host by mail. (And it’s an actual robot, and not just brains in a bucket.) Hopefully each host will have something interesting for the robot to do for the 24 hours allotted, like explore a local landmark, get a robot-eye view of the goings on in a hackerspace, or just watch the sunset in some beautiful spot. Project participants will get to drive the robot via a web interface and do a little virtual exploration of a part of the world they might never otherwise get to see.

We gather that the robot in the video below is only a prototype at this point, and that the sensor suite and mechanicals have yet to be sorted out. Hackaday regulars will no doubt know [Norbert] better as the excellently accented [HomoFaciens], creator of dumpster-sourced CNC machines, encoders made from tin can lids and wheels of resistors, and a potentially self-replicating CNC plotter. [Norbert] has the hacker chops to pull this off, and we think it’s a pretty neat idea with the potential to engage and educate a lot of people. We think it could do with a little support from the Hackaday community.

One Dollar Board Targets Students

May 16, 2016 by Al Williams 75 Comments

The Raspberry Pi was made to be inexpensive with an eye toward putting them into schools. But what about programs targeted at teaching embedded programming? There are plenty of fiscally-starved schools all over the world, and it isn’t uncommon for teachers to buy supplies out of their own pockets. What could you do with a board that cost just one dollar?

That’s the idea behind the team promoting the “One Dollar Board” (we don’t know why they didn’t call it a buck board). The idea is to produce a Creative Commons design for a simple microcontroller board that only costs a dollar. You can see a video about the project, below.

Why Kickstarter Products Fail

May 16, 2016 by Bob Baddeley 68 Comments

It seems every week we report on Kickstarter campaigns that fail in extraordinary fashion. And yet there are templates for their failure; stories that are told and retold. These stereotypical faceplants can be avoided. And they are of course not limited to Kickstarter, but apply to all Crowd Funding platforms. Let me list the many failure modes of crowdfunding a product. Learn from these tropes and maybe we can break out of this cycle of despair.

Failure Out of the Gate

You don’t hear about these failures, and that’s the point. These are crowd funded projects that launch into the abyss and don’t get any wings through printed word or exposure. They may have a stellar product, an impressive engineering team, and a 100% likelihood of being able to deliver, but the project doesn’t get noticed and it dies. Coolest Cooler, the project that raised $13 million, failed miserably the first time they ran a campaign. It was the second attempt that got traction.

The solution is to have a mailing list of interested people are ready to purchase the moment you launch, and share to everyone they know. Reach out to blogs and news organizations a month early with a press package and a pitch catered to their specific audience. Press releases get tossed. Have a good reason why this thing is relevant to their audience. Offer an exclusive to a big news site that is your target market.

Hackaday Links: April 24, 2016

April 24, 2016 by Brian Benchoff 8 Comments

The Internet Archive has a truck. Why? Because you should never underestimate the bandwidth of a truck filled with old manuals, books, audio recordings, films, and everything else the Internet Archive digitizes and hosts online. This truck also looks really, really badass. A good thing, too, because it was recently stolen. [Jason Scott] got the word out on Twitter and eagle-eyed spotters saw it driving to Bakersfield. The truck of awesome was recovered, and all is right with the world. The lesson we learned from all of this? Steal normal cars. Wait. Don’t steal cars, but if you do, steal normal cars.

In a completely unrelated note, does anyone know where to get a 99-01 Chevy Astro / GMC Safari cargo van with AWD, preferably with minimal rust?

[Star Simpson] is almost famous around these parts. She’s responsible for the TacoCopter among other such interesting endeavours. Now she’s working on a classic. [Forrest Mims]’ circuits, making the notebook version real. These Circuit Classics take the circuits found in [Forrest Mims]’ series of notebook workbooks, print them on FR4, and add a real, solderable implementation alongside.

Everyone needs more cheap Linux ARM boards, so here’s the Robin Core. It’s $15, has WiFi, and does 720p encoding. Weird, huh? It’s the same chip from an IP webcam. Oooohhhh. Now it makes sense.

Adafruit has some mechanical keyboard dorks on staff. [ladyada] famously uses a Dell AT101 with Alps Bigfoot switches, but she and [Collin Cunningham] spent three-quarters of an hour dorking out on mechanical keyboards. A music video was the result. Included in the video: vintage Alps on a NeXT keyboard and an Optimus Mini Three OLED keyboard.

A new Raspberry Pi! Get overenthusiastic hype! The Raspberry Pi Model A+ got an upgrade recently. It now has 512MB of RAM

We saw this delta 3D printer a month ago at the Midwest RepRap festival in Indiana. Now it’s a Kickstarter. Very big, and fairly cheap.

The Rigol DS1054Zed is one of the best oscilloscopes you can buy for the price. It’s also sort of loud. Here’s how you replace the fan to make it quieter.

Here’s some Crowdfunding drama for you. This project aims to bring the Commodore 64 back, in both a ‘home computer’ format and a portable gaming console. It’s not an FPGA implementation – it’s an ARM single board computer that also has support for, “multiple SIDs for stereo sound (6581 or 8580).” God only knows where they’re sourcing them from. Some tech journos complained that it’s, “just a Raspberry Pi running an emulator,” which it is not – apparently it’s a custom ARM board with a few sockets for SIDs, carts, and disk drives. I’ll be watching this one with interest.

Particle Electron – The Solution To Cellular Things

February 10, 2016 by Brian Benchoff 56 Comments

Just over a year ago, Particle (formerly Spark), makers of the very popular Core and Particle Photon WiFi development kits, released the first juicy tidbits for a very interesting piece of hardware. It was the Electron, a cheap, all-in-one cellular development kit with an even more interesting data plan. Particle would offer their own cellular service, allowing their tiny board to send or receive 1 Megabyte for $3.00 a month, without any contracts.

Thousands of people found this an interesting proposition and the Electron crowdfunding campaign took off like a rocket. Now, after a year of development and manufacturing, these tiny cellular boards are finally shipping out to backers and today the Electron officially launches.

Particle was kind enough to provide Hackaday with an Electron kit for a review. The short version of this review is the Electron is a great development platform, but Particle pulled off a small revolution in cellular communications and the Internet of Things
