Hi all, 

 

I'll link a few pictures when I get the chance but for now you get a description. 

 

Arcade machine is a 1980's era full size machine - made of chipboard and 30mm ply. Wrapped in some authentic (and pretty cool graphics). 

 

Originally it had a Steering wheel and pedals but those were broken, since gutted and are gone in favour of a dual (two player) joystick control layout.

 

Control buttons are wired to a keyboard emulator circuit (from ebay) which converts button presses into what a computer thinks is key presses (more reliable than USB gamepad emulator mapping) and sends it down as a "USB keyboard" with key presses to whatever PC/device you plug it into. 

 

Has a PC power transformer (so all internal wiring is just running on 12v max). This powers cooling, the LED light strip for top light, the RPi device (via USB 5v rail). Also powers a car stereo which is currently connected as the speaker amp! Although it also includes a (currently unused) amp controller which I'd intended to connect instead of the car stereo, because it's annoying to turn it on and then turn on the car stereo to AUX separately.

 

RPi 2 is pretty standard, has a case, loaded with PiMAME, which runs OK. Currently has a few odd games setup properly - Pacman, Asteroid, StreetFighter II. Includes a USB nano WiFi adaptor, so you can connect it to WiFI (using a USB keyboard to update wifi settings) and load up new games over the local IP web interface via web-browser. 

 

PiMAME works okay, only couple things: can get a bit techy to fix if anything does die (you need to know or know how to google your debian / Raspbian linux commands fairly extensively) loading games has worked pretty flawlessly so far, but the tricky bit is correctly mapping control pad keys to in-game keys, pimame has some emulator control panels to help with this, but fair warning - it's not what I'd call "plug-n-play". 

 

Has a 20-inch LCD monitor (4:3) inside mounted behind the glass which makes the whole thing super light. Also features a hidden exterior switch to turn on/off power to reset or turn on/off.

 

Has a HDMI to DVI adaptor for connecting the Raspberry pi to the monitor, and an AUX cable to connect the Rpi to car stereo amp. 

Added a couple wheels underneath so you can roll it around the garage pretty easily. Also have added a coin mech which accepts 50c coins, although not hard to bypass this with a button if youd rather have it coinless. 

Would like to see if there's any interest on GZ before potentially listing on TradeMe. 

Spent $110 on the unit, plus about $400 on parts. So I've spent about $500 total getting it to this point, plus a number of hours. I'd like to get $500 back but open to realistic offers.

 

Cheers, Kieran
