The Game: Screen Test

In the last post we successfully cut a hole in the TV screen to make space for the siren, so the next step is to secure it in place and make a translucent filter for the screen.

First though fitting that siren – as luck would have it I had a small metal 90 degree bracket that was exactly the right size to fit between the siren’s mounting bracket and the side of the TV case. The holes needed to be drilled out to hold larger bolts, but with a bit of fiddling it was rock solid.

Next was the screen filter. For this I printed a “TV Snow” image onto an A4 Transparency sheet (the kind you’d use in old-school overhead projectors) and then trimmed it around the existing screen with a craft knife. With everything test-fitted together I placed the assembly in front of the Pi prototype rig so that the Unicorn pHAT would shine through the screen. It looked just the way I had hoped, lots of indirect light and a bit of a glow to the screen, which will hopefully look even better when the inside of the TV is painted white.

Next time we’ll be moving on to the remote and the rabbit ears.

The Game: TV Teardown

The next stage in the “Game” project is to prepare the portable TV for its new function. Dismantling is always one of the most fun parts of a new project as you never know what to expect when cracking something open for the first time.

This teardown went really well, four screws to remove and a few snips with the wire cutters left just the outer shell, which is the bit we need. There’s also a convenient earphone socket left over that we’ll eventually use to plug in the LCD Glasses.

Now that the TV is in bits the next thing is to very carefully cut a hole in the plastic screen to hold one of the most critical parts of the game – the siren. Once that’s done we can start figuring out where all of the other parts will go, and how it will actually work.
