Making amazing digital projects out of recycled parts is a real joy. So imagine how happy we are to see BotchBoy: the cheapest Raspberry Pi games console ever.

BotchBoy was built by Joe Foulkes who wanted to make the cheapest GameBoy console around. As a matter of fact: no expense has been spent on this project. The total build cost is less than £15 ($20). And we love it.

For instance, Joe made the case out of an old Samsung Galaxy S4 box. For this build he followed an Instructables page by Tyler Spadgenske.

Building the cheapest Raspberry Pi games console

A Pi Zero and a portable power bank are glued inside the Samsung S4 Box. Also, holes are cut into the case for the buttons and screen. It's using a 2.4-inch display, which is wired to the GPIO pins (as are the buttons).

"The inspiration behind this project was that I wanted to make my own portable Raspberry Pi game system" says Joe, "and I wanted to make it as affordable as possible."

As a matter of fact, it may look a little rough around the edges, but the idea is sound. "The reason it's in a shoddy case, an old phone box, was for the thing to be affordable," he explains. "Total costs came to less than £15." That price includes the £4 for a Raspberry Pi Zero.

Speaking about the Instructables page, it shows some clever material usage. For example, the build materials include:

• Raspberry Pi Zero
• 2.4 inch TFT Display
• Lithium Ion Battery cell
• Prototyping Board
• Charging Circuit
• Micro USB Breakout
• 3v to 5v DC-DC Step Up Boost Converter

Indeed, the BotchBoy delivers a much better experience than its looks suggest. "The sound does work really well," says Joe. "It's pretty good. I paid about a pound for the USB audio."

"I was quite pleased with the results," says Joe, "I probably could have taken a bit more care when cutting holes out for the screen."

Not to mention that Joe isn't finished yet. "I'm going to be doing a version two of this then see if I maybe up by budget by five pounds then make it look a bit better."
