Don’t Steal This Laptop

September 22, 2015 by 74 Comments

As laptops have become smaller and easy to carry around, they have also picked up the most unfortunate property of being easy to steal. We’ve read the stories of how some victims are able to track them down via webcam still images of the thief. [Mastro Gippo] decided to take it one step further and add a remotely operated hardware self destruct to his laptop. The idea is if the laptop becomes unrecoverable, it will become useless and any sensitive data will be destroyed without harming the area around it.

It’s somewhat inception like, as it’s a hack within a hack. It’s based on the Crunchtrack, a CAN bus reverse engineering tool equipped with GPS and a SIM800 GSM module, which was also developed by [Mastro Gippo]. The idea is to tuck the small board somewhere in the laptop and wire it up between the battery and some sensitive parts. Send a single SMS text and ‘poof’, bye-bye laptop.

He wrote all the code in less the 24 hours for the BattleHack Hackathon. He decided to spice up the act with some firecrackers and a detonator, which made his team the crowd favorite and earned a victory.

KeyMouSerial Solves Your Raspberry Pi Keyboard Problems

June 27, 2015 by 36 Comments

All laptops have a working keyboard and mouse built into them, the only problem is that you can’t use these tools on other computers that don’t have them. At least, until now. [Peter] has created the KeyMouSerial in order to use his laptop’s keyboard and mouse as physical devices on his Raspberry Pi, finally freeing the bonds holding our laptops’ human interface devices back.

The software for KeyMouSerial copies keystroke and mouse information and sends this out via a serial port on his laptop (using a USB to serial adapter). From there the information is translated by an Arduino into HID commands which are sent via USB to the target computer, in this case a Raspberry Pi. It’s a pretty elegant solution to carrying a bulky keyboard and mouse along just for a Raspberry Pi, or for any computer that might not have access to a network and SSH.

[Peter] has also been working on using his iPod as a serial-to-USB converter, so if you’re a Rockbox developer and want to help out then drop him a line. All of the software is available (for Windows, Mac, or Linux) including the Arduino sketch if you want to try this software out for yourself. And, if you don’t want to turn a computer into a keyboard and want to go the other direction and turn a keyboard into a computer, that is also an option.

Simple Terminal Hack Is Fit For Hollywood

November 25, 2014 by 21 Comments

We’ve all seen the cheesy hacker scenes in movies and on TV. Three dimensional file system browsers, computer chip cityscapes, and other ridiculous visualizations to make the dull act of sitting at a keyboard look pretty on the silver screen. While real hackers know those things are often silly and impractical, sometimes we do go out of our way to pretty things up a bit.

Hollywood might be able to learn a thing or two from this latest hack. [Yuri] modified his Linux terminal to change the color of the back lights on his laptop’s keyboard. It’s the kind of thing that actually would look good in a modern hacker movie, and [Yuri] is living proof that it’s something that a real-life hacker would actually use!

[Yuri] has been running Simple Terminal. The Simple Terminal project aims to build a replacement for the default xterm program that removes all of the unnecessary features and simplifies the source code. It also aims to make your terminal experience prettier. Part of making things prettier means that you can choose the font color for your terminals, and of course each terminal window can have its own color if you so choose.

[Yuri] happens to own an Alienware laptop. This laptop comes with RGB LEDs behind the keyboard, allowing you to light them up just about any color you could ever want. [Yuri] thought it would be cool if his keyboard color matched the font color of his terminal windows. Thanks to AlienFX, he was able to write a simple patch for Simple Terminal that does exactly this. Now whenever he selects a terminal window, the keyboard automatically switches colors to match the text in that window. Be sure to check out the video below.

Did you know that Hackaday.io has a hackerspace index? That’s right, you can enter your local hackerspace’s info, pictures, videos, and social media links. Members and crew can link their hackaday.io profiles and drop comments about their latest projects.

The map up at the top of the hackerspace index’s page is interactive too – zoom in on your country and local area to see any spaces nearby. It’s like one-stop shopping for awesome. Well, except that this awesome is free.

It really is great to see all the pictures of spaces large and small. Some of the most stunning shots are from c-base, in Berlin, Germany. Founded in 1995, the c-base crew have created an incredible space. Take a look at the workstation in the photo. Is it Steampunk? Matrix-punk? Heck no, that’s 100% c-base.

Do It Yourself Laptops

You don’t have to be Bunnie Huang to build your own laptop. All it takes is some time, ingenuity,and a good hot glue gun.

opentech-laptop

Our first laptop is actually inspired by Bunnie’s Novena. The OpenTech-Laptop uses two binders as it’s shell, but inside hides some decent computing power. [OpenTech] used a miniITX motherboard with an ATOM N2800 CPU. The screen came from an old laptop (long live matte 4:3 screens!) [OpenTech] even hand wired a Low Voltage Differential Signaling (LVDS) cable so the motherboard can push those pixels. A wireless keyboard, hard drive, and speakers round out the build. [OpenTech] is still looking for a portable power solution.Why not follow Bunnie’s lead and grab some R/C Plane LiPo batteries, [OpenTech]?

Next up is a MiniBSD laptop computer created by [Jaromir]. MiniBSD is based on RetroBSD, a PIC32 based BSD single board computer. Rather than use a premade platform like the Fubarino, [Jaromir] laid out his own board with everything he wanted – a microSD socket, SDRAM, real-time clock, and all the trimmings. He then added a graphical LCD, a LiPo battery, and a sweet retro keyboard from an old Czech computer company called Tesla. [Jaromir’s] next task is a 3D printed case. The only problem is the case is 2cm wider than his current printer’s bed!

You didn’t think we’d leave the Raspberry Pi out, now did you? Laptop-pi is [Bram’s] project to convert an old DVD player (remember those?) into a Pi Laptop. Not only did [Bram] build a QWERTY keyboard from scratch on perfboard, he also hacked together an on-screen keyboard so he can type with just a D-pad. He’s currently fighting with a dodgy audio amp, but we’re sure that’s just a temporary setback. We think Laptop-pi will be a killer portable for retro gaming!

 

That’s it for this week’s Hacklet, stay tuned for next week when we bring you more of what’s happening at Hackaday.io!

[Bunnie]’s Open Source Laptop Is Ready For Production

January 12, 2014 by 60 Comments

Just over a year ago, [Bunnie Huang] announced he was working on a very ambitious personal project: a completely open source laptop. Now, with help from his hardware hacker compatriot [xobs], this laptop named Novena is nearly complete.

Before setting out on this project, [Bunnie] had some must-have requirements for the design. Most importantly, all the components should be free of NDA encumbrances. This isn’t an easy task; an SoC vendor with documentation sitting around on their servers is rare as hen’s teeth, and Freescale was the only vendor that fit the bill. Secondly, the entire laptop should be entirely open source. [Bunnie] wasn’t able to find an open source GPU, so using hardware video decoding on his laptop requires a binary blob. Software decoding works just fine, though.

Furthermore, this laptop is designed for both security and hardware hacking. Two Ethernet ports (one 1Gbit and the second 100Mbit), a USB OTG port, and a Spartan 6 FPGA put this laptop in a class all by itself. The main board includes 8x analog inputs, 8x digital I/O ports, 8 PWM pins, and a Raspberry Pi-compatible header for some real hardware hackery.

As for the specs of the laptop, they’re respectable for a high-end tablet.  The CPU is a Freescale iMX6, a quad-core ARM Cortex-A9 running at 1.2 GHz. The RAM is upgradeable to 4GB, an internal SATA-II port will easily accommodate a huge SSD, the ability to use an LCD adapter board to run the 13-inch 2560×1700 LED panel [Bunnie] is using. The power system is intended to be modular, with batteries provided by run-of-the-mill RC Lipo packs. For complete specs, check out the wiki.

Despite the high price and relatively low performance (compared to i7 laptop) of [Bunnie]’s laptop, there has been a lot of interest in spinning a few thousand boards and sending them off to be pick and placed. There’s going to be a crowd funding campaign for Novena sometime in late February or March based around an “all-in-one PC with a battery” form factor. There’s no exact figure on what the price of a Novena will be, but it goes without saying a lot will be sold regardless.
