Original hardware for fifteen consoles jammed into recently completed Project Unity

This boxy monstrosity is big for a reason. It lets you play games on the original hardware of fifteen different gaming consoles. That’s right, we said original hardware. One of the main goals of Project Unity was to keep the stock equipment by making any type of emulation — hardware or otherwise — taboo. The size of the case is a function of how much stuff is actually crammed in there. But the final shape was dictated by the available opening in [Bacteria's] living room entertainment center.

The video after the break walks us through each aspect of the build. We’re floored by the quote of 3,500 hours of build time. But as you get a look at the wiring-hell of each different module it’s easy to understand why it didn’t just build itself. One power supply and one controller make for the least complicated user experience possible. We already looked at a giant switching mechanism that selects one console at a time and the singular controller unit. But [Bacteria] has a lot of other tricks up his sleeve which make this gold mine of a hacking reference piece.

Making a gigantic 18 pole 16 throw switch

When you’re building something that hasn’t been done before, sometimes the parts you need just don’t exist.

[Bacteria] over on the Made by Bacteria forum is building a huge all-in-one video game machine, combining hardware from 16 different consoles released through the years. This build requires a way to switch the video output between consoles, so [Bacteria] made a gigantic 18 pole 16 throw switch.

The build began with [Bacteria] sourcing a few 8-pole switches. Of course this switch was too small to toggle between the 16 output lines for each system, so these switches were doubled up and activated by a single button. This system worked, but the results weren’t ideal.

[Bacteria] gave in to the temptation of building his own switch by using spring-loaded metal nuts as the contacts for each part of the switch, allowing him to switch between consoles with a simple sliding contact.

So far, it looks like [Bacteria]‘s Project Unity is shaping up nicely. We’ve seen a bit of the controller portion of [Bac]‘s build, and already it’s shaping up to be a wonder of retro gaming.
