Retrofit a handheld Casio portable TV with a Raspberry Pi

What do we say to the god of outdated tech? Not today! Revive an old portable television with a Raspberry Pi 3!

Pocket televisions

In the late 1980s, when I was a gadget-savvy kid, my mother bought me a pocket TV as a joint Christmas and birthday present. The TV’s image clarity was questionable, its sound tinny, and its aerial so long that I often poked myself and others in the eye while trying to find a signal. Despite all this, it was one of the coolest, most futuristic things I’d ever seen, and I treasured it. But, as most tech of its day, the pocket TV no longer needed: I can watch TV in high definition on my phone — a device half the size, with a screen thrice as large, and no insatiable hunger for AA batteries.

So what do we do with this old tech to save it from the tip?

We put a Raspberry Pi in it, of course!

JaguarWong’s Raspberry Pi 3 pocket TV!

“I picked up a broken Casio TV-400 for the princely sum of ‘free’ a few weeks back. And I knew immediately what I wanted to do with it,” imgur user JaguarWong states in the introduction for the project.

I got the Pi for Christmas a couple of years back and have never really had any plans for it. Not long after I got it, I picked up the little screen from eBay to play with but again, with no real purpose in mind — but when I got the pocket TV everything fell into place.

Isn’t it wonderful when things fall so perfectly into place?

Thanks to an online pinout guide, JW was able to determine how to  connect the screen and the Raspberry Pi; fortunately, only a few jumper wires were needed — “which was handy given the limits on space.”

With slots cut into the base of the TV for the USB and Ethernet ports, the whole project fit together like a dream, with little need for modification of the original housing.

The final result is wonderful. And while JW describes the project as “fun, if mostly pointless”, we think it’s great — another brilliant example of retrofitting old tech with Raspberry Pi!
