If you're looking for a creative use of a Raspberry Pi, or maybe just want to get your retro game on, this DIY coffee table arcade machine is perfect for you. You'll need some supplies, but Instructables user grahamgelding will show you how it's done.
Grahamgelding used a used 24-inch monitor, a Raspberry Pi in a case, an old set of computer speakers, an arcade stick and recycled wood to make this project a reality. He cut off the edges of the table to make it child friendly, and added a sheet of perspex over the screen to protect it from anything spilled on the display. Then he added the speaker, and using a circuit from the set he cannibalized, he even added a headphone jack in case someone else was trying to watch TV in the same room.
It's a pretty creative use of a Raspberry Pi, and an affordable hack altogether — the most expensive component was probably the monitor. If you're interested in making one of your own, hit the link below for a step-by-step with more photos of the finished project.
