Does it seem like everyone you game against can do everything faster than you? Chances are good that they have some kind of dedicated game pad or macro pad with a bunch of custom shortcuts. If you can’t beat ’em, join ’em, but why buy one when you can build your own? [lordofthedum] did the smart thing when they built their own version of the Azeron game pad, which is an outrageously expensive but ergonomic and cool-looking macro pad that reminds us of the DataHand ergonomic keyboard.
Each finger hovers over a C-shaped group of three switches — one actuates by moving the finger forward, another by moving backward, and the third by pushing down like a regular button. The thumb gets a 4-way joystick. All of these inputs are wired up to an Arduino Pro Micro, which has sort of become the standard for DIY macro pads and keyboards. We think this looks fantastic, and really raises the bar for DIY macro pads.
Need a few more keys, but still want a thumb joystick? Check out the smooth and sweet Sherbet game pad.
When [Billiam]’s beloved Logitech G13 game pad went to that great spectate room in the sky, he decided to pay homage by designing a custom, more ergonomic replacement from the desk up. Grab a spoon and dig into the story of [Billiam]’s journey toward Sherbet, because it’s a sweet ride.
Here’s the scoop: like a lot of DIY game pads and keyboards, Sherbet is based on the Teensy. We often see the micro USB coming straight off the Teensy, especially in clear acrylic builds, but [Billiam] added a USB breakout board so there’s no direct stress on the Teensy itself.
One of [Billiam]’s design challenges comes from the game pad placement — he has a tall desk and uses a keyboard tray, so it has to fit the space and leave enough room for his hand. Fortunately, there are low-profile mechanical switches out there, although the keycap options are strongly limited. We love that [Billiam] embedded a tiny ceramic bearing into one of them to use as a homing bump, because that’s a great idea.
If you want to take a crack at this project, [Billiam] has all the goodies laid out. [Billiam] wanted to use QMK firmware, but they didn’t have joystick support yet, so he’s got an Arduino sketch running in the meantime.
We love a good custom game pad around here, especially if they can reprogram themselves.
[Quinn Dunki] has been hard at work building a Teddy Top – an Apple IIc Plus modified for a road warrior. It has a 3.5 inch disk drive, runs at a blistering four megahertz, and has a beautiful integrated color LCD. It would be a shame to have such a great machine and no way to play games as they were intended, so [Quinn] set about building a game pad for her lovable Apple II.
The Apple II joystick port isn’t as simple as an Atari or Commodore joystick port. Where the bog-standard Atari joystick is basically just a bunch of switches connected to pins, the Apple II joystick is analog. Weird, and even weirder is the value of the pots in these joysticks: 150kΩ. Somehow or another, nobody makes pots in this value any more. Luckily the hardware in these joysticks is well documented, and shoehorning in modern components isn’t that bad.
The Apple joystick has a bit of circuitry – a 556 timer chip that reads the values of each pot and converts that into a stream of 0s and 1s for the Apple. The joystick [Quinn] found for her game pad is an analog thumb stick on a neat breakout board manufactured by Parallax. This analog joystick has 10kΩ pots in it, and that just won’t work with the 556 timer chip. However, since this is just resistors and a 556 chip, adjusting some of the values on the original schematics does the trick. [Quinn] added a few capacitors to her circuit, and everything worked beautifully.
With the electronics down, she turned her attention to the case for her Apple II road warrior enclosure. She recently picked up a 3D printer, which means she’s new to 3D printing. After spending a few hours designing a controller in 123D Design, she sent the files over to the printer. Warping happened. She tried an ABS slurry. The part was stuck to the bed. It took a few tries (purple glue sticks are awesome, [Quinn]), but she eventually got her plastic enclosure printed out, and the circuitry installed. The result is a portable computer, with a custom controller, playing Lode Runner. Can’t beat that.
[Ben Heckendorn]’s Access Controller is now shipping. The controller is designed to be used with just one hand. It has six openings that the five control modules can be placed in. It’s easy to reconfigure depending on the player or game. While the prototype was built using Xbox 360 controller parts, this newly released unit is available for the PS2, PS3, and PCs. The Xbox 360 version is still being reviewed for final production. [Ben] says that in the coming weeks he’ll post a how-to for building your own modules. There’s always one empty slot and the bus like design should make this fairly simple.
