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.
