Like many of us, [Alex] spent a large part of his childhood feeding coin after coin into one arcade game or another. Galaga is one of his all-time favorites, and he has wanted to build a Galaga cabinet for a long time. Once his workshop was ready for the job, it was time to cross it off the list.
The cabinet is built to 4/5 scale. This is a great size because he gets the stability and feel of a full-size machine, but it’s much easier to move it around. As you might expect, there’s Pi in the cabinet. The display is an old TV that [Alex] found in a Dumpster. And although it works great, it would go into standby instead of powering off along with everything else. To get around this, [Alex] built an automatic remote control with an IR LED and an Arduino Diecimila. After a five-second wait, it sends the power-on code to the TV and switches the input. The TV is supposed to be in portrait mode for Galaga, but this proved to be a challenge. Changing the orientation at the Pi level resulted in poor performance and choppy sound, so he changed it at the game execution level.
We are continually impressed by the diversity of [Alex]’s builds and the care that goes into them. Who could forget his beautiful sidewalk graffiti machine or the time he showed us how to photograph stuff that’s not there?
