    Smashed tablet in NES case lives out its days as an emulator

    hackaday.com 26 Feb '13, 11pm

    The creator of this project started off with a 7″ tablet he received from a coworker. The screen was horribly smashed from one corner spreading out through the entire surface. But the hardware inside still worked, including the HDMI out port. He ended up transplanting the tablet hardw...

    Massively parallel CPU processes 256 shades of gray

    hackaday.com 26 Feb '13, 5pm

    The 1980s were a heyday for strange computer architectures; instead of the von Newmann architecture you’d find in one of today’s desktop computers or the Harvard architecture of a microcontroller, a lot of companies experimented with strange parallel designs. While not used much today...

  • Taking the pain out of making custom Eagle parts

    Taking the pain out of making custom Eagle parts

    hackaday.com 26 Feb '13, 3pm

    One thing that’s really convenient for custom Eagle parts is that most components are DIPs or some sort of leaded SMD component. [Dave]‘s script takes the dimensional data from any chip’s datasheet and creates a custom outline for each part. The inputs and outputs can also be ripped d...

  • Giving 3D printed parts a shiny smooth finish

    Giving 3D printed parts a shiny smooth finish

    hackaday.com 26 Feb '13, 1pm

    Beware that smoothing 3D printed parts with a solvent is PATENTED, just like many other OBVIOUS little things you can do while making 3D printed parts also have been granted ridiculous patents. Some obvious examples are: 1) Keeping your 3D printer at a warm temperature in a temperatur...

    Hacking the International Space Station with a toothbrush

    hackaday.com 26 Feb '13, 11am

    [Douglas Adams] will tell you not to forget your towel when it comes to space travel. But NASA may start mandating that astronauts always carry a toothbrush. That’s because when a recent repair on a critical International Space Station component went wrong it was a toothbrush hack tha...

    Automatic beer pourer was hacked together from a bit of everything

    hackaday.com 26 Feb '13, 3am

    Many of the parts come from a washing machine that the team scrapped for the build — most notably the motor which drives the belt. But pretty much every part of it is salvaged. For instance, the conveyor belt that transports the full glasses was made from gluing sections of bicycle in...

    Laser Kaleidoscope uses more 3D printing and less scavenging

    hackaday.com 26 Feb '13, 1am

    At first we thought that [Pete Prodoehl] was using the wrong term when calling his project a Laser Kaleidoscope . We usually think of a kaleidoscope as a long tube with three mirrors and some beads or glass shards in one end. But we looked it up and there’s a second definition that me...

    [Art Barrios] kept having night-time visitors who were raiding his dog’s food storage bin. It’s a plastic tub with a lid that latches but the critters were knocking it over and popping that lid off. He wanted to find out which animal was the culprit so he hacked together an automatic ...

  • Using a flashing LCD monitor to transfer data

    Using a flashing LCD monitor to transfer data

    hackaday.com 25 Feb '13, 7pm

    We love the concept of using an LCD screen to transfer data. The most wide-spread and successful method we know of is the combination of a QR code and the camera on a smart phone. But for less powerful/costly devices data can be transferred simply by flashing colors on the screen. Tha...

  • Ubuntu with a GUI on a Beagleboard

    hackaday.com 25 Feb '13, 5pm

    The Raspberry Pi is great if you’re looking for a cheap yet powerful computer running Linux, but let’s not forget all the other ARM dev boards out there. [Adam] spent some time this weekend putting together an Ubuntu distro for his Beagleboard XM to give it the convenience of a GUI an...

    Modifying a printer for PCB fabbing

    hackaday.com 25 Feb '13, 1pm

    The migraine-inducing image above is the product of [Rupert Hirst]‘s attempts at home PCB fabrication. He’s using the toner transfer method – printing a circuit on a piece of transparency sheet with a laser printer, setting it on a piece of copper clad board, and sending the whole ass...

  • Building huge displays with LED strips

    Building huge displays with LED strips

    hackaday.com 25 Feb '13, 11am

    Building RGB LED displays is one of the most interesting programming and engineering challenges we see here on Hackaday. Not only do the creators of large displays and LED cubes have to deal with the power requirements of driving a whole bunch of LEDs, but there’s also the issue of ge...

  • Arduinofied QRP radio beacon

    hackaday.com 24 Feb '13, 7pm

    A while back, [m0xpd] picked up an unbearably cheap AD9850 DDS module from ebay. He turned this in to a Raspberry Pi-powered radio beacon, but like so many builds that grace our pages, the trolls didn’t like using such an overpowered computer for such a simple device. To keep those tr...

  • A remote-controlled, autonomous kite generates power

    hackaday.com 24 Feb '13, 5pm

    Autonomous: “not subject to control from outside; independent.” Remote Control: “control of a system or activity by a person at a different place” Please don’t write “remote-controlled, autonomous” as a description for anything. They pretty much mean opposite things! This is one of my...

  • Multibooting the Raspberry Pi

    Multibooting the Raspberry Pi

    hackaday.com 24 Feb '13, 1pm

    Those of us have been dual booting Linux, Windows, and OS X operating systems for a while will be familiar with bootloaders such as GRUB and its ilk. Surprisingly, though, we haven’t seen a bootloader for the most popular computer of the last year – the Raspberry Pi. It makes sense to...

  • Automated pH Control

    hackaday.com 23 Feb '13, 7pm

    Controlling the pH level of a solution is usually a tedious task. Adding an acid or base to the solution will change the pH, but manually monitoring the levels and adding the correct amount isn’t fun. [Reza] rigged up an automated pH controller to keep a solution’s pH steady. The buil...

  • Tickle-Me-Elmo… Frozen In Carbonite

    hackaday.com 23 Feb '13, 5pm

    We at [HAD] love any hack that combines children’s toys with science-fiction technology, so seeing a Tickle-Me-Elmo “frozen” in [Carbonite] is a definite win in our book. It’s also a great argument for joining your local Hackerspace, or just getting together with some like-minded frie...

  • An industrial RepRap

    hackaday.com 23 Feb '13, 3pm

    It may just be another 3D printer, but [Jonas] and [Simon]‘s Kühling & Kühling RepRap Industrial is a cross between a work of art and a beautiful machine tool. It also looks to be a pretty nice 3D printer, to boot. The Kühling RepRap is built out of 20mm t-slot aluminum with plastic s...

  • WeMo without a smartphone

    hackaday.com 23 Feb '13, 1pm

    this Python script used for WeMo hacking . It was originally meant to issue commands to the outlet once it had passed the initial setup. [Matt] followed along but couldn’t get an answer on the port he expected. It turns out that the device listens on a different port until the initial...

  • Smartphone controlled Labyrinth

    hackaday.com 23 Feb '13, 3am

    This entire project could have been done as an app, drawing the maze and ball virtually on the screen. But that wouldn’t have been nearly as fun as what [Matt] accomplished. He built a little Labyrinth which responds to the accelerometer in his phone . Take a close look at that handse...

  • Dissecting a firmware image

    hackaday.com 23 Feb '13, 1am

    [Leland Flynn] did a great job of picking apart the firmware image for a Westell 9100EM FiOS router . Unfortunately he didn’t actually find the information he was looking for. But he’s not quite done poking around yet either. If you have never tried to make sense of an embedded Linux ...

    Door hidden by bookcase is a marvel of DIY engineering

    hackaday.com 22 Feb '13, 7pm

    Possibly the most important part of the build is figuring out how to hinge all the weight a bookcase will carry. His solution was to use a set of four heavy-duty casters. He cut off the wheels from one pair and the mounting brackets from another. By welding the brackets on in place of...

  • Panelizing PCBs in Eagle

    hackaday.com 22 Feb '13, 5pm

    A lot of the board houses out there including Seeed and ITead studios have a fixed size for circuit boards before the price goes up. A one-inch square board costs the same as a much larger 5cm x 5cm board, making panelized PCBs a great way to get more boards for the same amount of mon...
