Karma Controller Makes Reddit A Game

[Will] likes Reddit so much he built this dedicated controller that lets him play the social website like a video game.

He calls it he Karma Controller. In this case, ‘Karma’ refers to ability to accumulate a large number of net up-votes on a Reddit post. The device features seven buttons which are all it takes to up and down vote, navigate up and down on the Reddit listings, toggle images, as well as open and close new tabs for the comments section. We’re wondering if it allows you to follow a link to the post source too?

One of the reasons that we’re featuring this is that it’s only [Will’s] second electronics project. If you’re still reluctant to get your hands dirty we hope this acts as inspiration. He started by building the first version on a hunk of protoboard. The Digispark microcontroller seen at the top reads from his button network and communicates with the computer via USB. Once the design was proven he had some help etching this circuit board which is version 2. He shows it off in the clip after the jump.

If you just want some buttons for voting you should take a look at this project which includes a 3D printed enclosure and button covers.

Atari Combo Controller Has What You Need For Any Cartridge

Retro gaming enthusiasts take note: this joystick is what you need to play any Atari game on the original console. It plugs right into the original console hardware and removes the need to choose the joystick, paddle, or keypad controller separately. You just leave this puppy hooked up and move your hands to the set of controls used on each game.

[x2Jiggy] built the thing from scratch. The enclosure is a wooden box from the craft store. He holds it closed with a couple of magnetic latches like you might find on old fashioned kitchen cabinets. The buttons of the keypad are mounted on a chunk of protoboard but he did take the time to give it a coat of matching paint so that it doesn’t look out of place. Inside you’ll find some more protoboard and point-to-point soldering to complete the rest of the connections.

You can see a fast motion video of the build process after the break. This reminds us of the universal controller built for Project Unity.

Sega Controller Houses Auto-launch Emulator

April 29, 2013 by Mike Szczys 17 Comments

[Joe’s] wife grew up playing Sega games and he wanted to help her unwind by reliving the experience. Since the work computer she uses when travelling isn’t a good place to install emulators he built this plug-and-play emulator inside of a Sega controller.

We’ve seen this type of thing a few times before (even with XBMC in a SNES controller) but there is one thing we hadn’t thought of lately. Newer versions of Windows have auto-launch disabled for USB drives. But [Joe] knew that there were still some USB sticks that manage to auto-launch anyway so he researched how those work. It turns out that they have two partitions, one is formatted as a CDFS which looks like a CD-ROM to Windows and allows auto-launch. He used this method of partitioning a USB stick, storing the ROMs on the mass storage partition and the emulator and the CDFS partition. To finish the hack he cracked open the controller and found room for a USB hub and the PCB from the thumb drive.

If you still have cartridges lying around you can pull the ROMs off of them over USB.

Drop-in Pcb Makes Nintendo Four Score A USB Joystick

April 21, 2013 by Mike Szczys 12 Comments

The Nintendo Four Score was a controller attachment for the original Nintendo Entertainment System which allowed you to use four controllers at one time. [Simon Inns] wanted to use some original NES controllers on his computer so he developed a drop-in replacement board that converts the device to USB.

As we’ve seen with other NES controller hacks, the hardware uses a simple parallel to serial shift register to deliver key-presses to the console. This means that reading four controllers at a time is no different than shifting in data to a microcontroller from the four different sources. The remaining portion of the problem is providing a USB connection that enumerates the device as a joystick. We’ve seen a bunch of USB projects from [Simon] so it’s no surprise that he was able to pull it off.

He went with the ATmega16U2 which has built-in support for USB. [Simon] wrote the code so that although there is only one USB cable, each of the four controller ports will appear as a separate USB joystick on the computer. To button up the project he carefully measured the original board and laid out his own version so that it fits the footprint of all the original components as well as the mounting brackets on the case. Top notch [Simon]!

Horribly Complicated Electric Guitar Keyboard

Gutarist, hacker, and mustache enthusiast [David Neevel] brought together way too many pieces of hardware in order to use his electric guitar as a computer keyboard.

So let’s dig into the house of cards he built for the project. It starts off with the guitar which has been fitted with an additional pickup to interface with a Roland GR-33 synthesizer pedal. That outputs a MIDI signal, which many hackers would have connected to the computer and parsed with a simple script. But not [David], he connected it to an Arduino via an optisolator. Well that’s not too ridiculous, right? Don’t you think he’ll just parse the MIDI signals and push them to the computer via the Arduino’s USB port? Wrong! He translates the MIDI signals into combinations for a big relay board which is emulating the key matrix of an old USB keyboard. But as you can see in the demo video after the jump it works quite well.

If you’re more of the drumming sort there’s an electric drum set version of this hack too.

Automating A Mechanical Typewriter

Check out all the work going on in the cabinet below this typewriter. The hack which automates a mechanical typewriter is for an art installation, but wouldn’t it be fun to build one of these to use as a résumé printer? It really makes us wish we had an old typewriter sitting around.

It would have been much easier to patch into an electric typewriter, but we have seen the string trick used on those as well. In this case a loop of string attaches to the the bar under each key, allowing a pull from below to type the character. An automotive door lock actuator ([Harvey Moon] tells us they’re not solenoids) connects to the other end of the string for every key. But then you’ve got to have a way to drive the actuators and that’s where the protoboard full of forty relays seen to the right comes into play. That image, which was taken from the demo video after the break, shows the board being testing. We’d guess more wires are added later to multiplex the array as we can’t figure out how the Arduino manages to drive all forty of them as shown. One thing we are sure about, the completed project looks and sounds amazing!

Wall Wart Computer Mouse

This rather bulky looking wall wart is actually a computer mouse. Sure, it may cause your hand to cramp horribly if used for any length of time. But some would say it’s worth that for the hipster value of the thing.

The rather odd shape is somewhat explained by the fact that this was sourced from Ikea. After gutting the transformer found inside the plastic case he had plenty of room to work with. He drilled a hole so that the sensor from a Logitech USB optical mouse can pick up the movement of the mouse. He also got pretty creative when it came to the buttons. The two prongs of the wall plug pivot horizontally to affect the momentary press switches inside.

After the break you can see a quick demo of the project. [Alec] doesn’t consider it to be complete. He wants to make a couple of improvements which include adding weight to make it feel more like the original wall wart, and finding a way to hide the hole he drilled for the sensor.
