Recently, a friend of ours got married who is a Ms. Pac-Man fanatic. His best man set out to fulfill the groom’s dream of owning a Ms. Pac-Man cocktail cabinet. The problem is that the unit he was after was selling for $2500. It’s great to buy the real thing (and with guest contributions he did,) but if it’s not available consider building your own.
[Alex] has put together a comprehensive guide for building a MAME cocktail cabinet. Unlike the mini-cabinet we saw last week, this is intended to be used sitting down and features controls on more than one side. His guide details the use of an original arcade CRT or an LCD flat panel, high-end controls via an I-Pac 4 controller, and a PC running MAME and MaLa software for Windows. The result is a professional looking build with controls on three sides of the table.
For those that are lucky enough to remember it, Lunar Lander was a fantastic game. Though it had simple vector graphics and highly repetitive game play, it kept us captivated. We probably lost entire weeks of our lives competing with friends to be the best. Well, now we can relive that experience with a physical version of the game. [Lain] built this fantastic arcade style game to replicate Lunar Lander’s game play exactly. The style of the project is fantastic with giant analog meters and dials giving real time feedback. You even get a prize if you complete all 3 levels. You can get plenty of build details by going through his blog. Maybe he should hook up with the folks that built the Apollo landing computer replica to build the ultimate simulator.
[Perry's] awesome AcceLED Pong project gives new life to a classic game by adding acceleration-based control. The pong paddles are moved by tilting the circuit left or right. Motion is measured by an ADXL203 dual axis accelerometer, and an ATMEGA32 microcontroller converts acceleration into ball and paddle movement. The game display is a three-color SparkFun 8×8 LED matrix with serial interface.
m8ta fun did an extensive teardown of OCZ’s Neural Impulse Actuator (NIA). OCZ’s computer/mind interface is actually a fairly straight forward design. An analog front-end cleans and amplifies the ‘neural’ signal with a few op-amps before feeding it to a 24 bit analog to digital converter (ADC). A USB enabled PIC microcontroller reads the 24bit parallel ADC output through a common 7400 series parallel to serial adapter IC. The device has an ICSP programing header (top right), though it’s not yet clear if the PIC can be read or written.
USB NES controllers are old school these days, but [Jay] put together a nice new take on the project. He shoehorned a USB interface adapter, USB hub and a USB memory stick to store his collection of NES roms and emulators right on the controller. He even dug up a black USB cable to keep the original look of the controller. Now he can just plug in and load his game selection directly from the controller.
Today, [sprite_tm] let us in on one of his pet projects. This is an inexpensive portable game platform runs about $50 and happens to use an ARM CPU and a 320×240 color LCD. Because it’s so cheap, he’s been working on reverse engineering the thing and there’s already a proof of concept homebrew version of Pong out for it. Update: Yeah, yeah – title’s fixed.
[sprite_tm]’s back with one of his excellent Atmel projects. This time he decided to turn an original XBox controller (cause he likes ‘em) into a standard USB HID device. He gutted the custom USB chip that Microsoft installed and replaced it with an Atmel ATMega88. The ATMega required a few changes to the board, but nothing too off the wall.
[Elf] sent in this interesting DIY joystick glove. There aren’t many details on the actual glove switch design, but from the schematic on the site, it seems to mostly consist of micro-switches with some pot adjusted transistors to calibrate the X-Y signals.
Building on his USB NES pad interface, [Raphaël] released a universal USB joystick interface. It presents a HID device with four directional buttons and eight general purpose buttons. The board uses an ATmega8 and implements USB entirely in software.
The Universal PCB project lets you make any controller (specifically arcade sticks) console agnostic. A PIC microcontroller is used to translate between the button presses and the signals for the specific console you’re connected to. It uses a DB15 for the external plug. The PIC knows which console you’re plugged into based on which pins are high or low in your console specific adapter cable. The board includes a piggyback plug so you can plug in an Xbox360 controller board (like the one above) since the console requires authentication. The PIC’s firmware is conveniently upgradeable over the USB cable.
