I featured a K’Nex rollercoaster a while back and it brought back memories of the K’Nex toys I had. Well, now someone has built a K’Nex pinball machine. That “someone” is Tyler Bower and the machine is a beast:
Where do we even start? This is a full-size pinball machine, as in 7′ tall, 5′ long, and 3′ wide. [Tyler] estimates that it’s made from about 16,000 pieces, or around 73 pounds of plastic, much of which was obtained locally and is secondhand. Many of those pieces make up the ten drill motor-driven chain lifts in the back — these move the ball through the machine after it goes through one of the track triggers and return it to the playfield in various delightful ways.
Speaking of ways to score, there are nine of them total, and some are harder to get to than others. They all involve some really amazing K’nex movement, and each one uses aluminum foil switches to trigger scoring through a MaKey MaKey.
In some ways, it reminds me of Mouse Trap (the board game) but with a lot more engineering.
