This Pi-based game is coming together nicely, the hook remote went just as planned so Rabbit Ears are next. To be honest I put this part off as long as possible as there was a lot of potential for disaster.
I’ll cover the concept of the game in a bit more detail next time, but suffice it to say that a critical component is a TV aerial, bent up to form a kind of maze to negotiate with the hook remote.
Bending a TV aerial into a nice stable shape is much trickier than it sounds! The connections between the sections are pretty fragile, and even after heating the chrome tube is liable to kink when you bend it, leaving a really weak joint.
Several tests and destroyed aerials later I came across a solution- keep the design simple and make a smooth curve by “nipping” the aerial in multiple places with needlenose pliers. This gave much more control over the bend and I was able to replicate the same curve in both “ears”. You’ll see when the video is released that this was quite a tense moment!
With the ears in good shape they then needed to be wired to a cable for connection to the Pi, which was straightforward as I just re-used the existing screw connectors.
Next I re-used the tip of one of the aerials I destroyed in testing to make a “Finish” button, wired to a different GPIO pin on the Pi. Now that the project is beyond the “danger zone” I’ll look at the overall concept in the next post.

Once complete there will be a full YouTube video so you can follow along and make your own!
