With Jaws becoming a real set, TheBananaMan still needs 4,000 more votes for his LEGO Turing Machine to be considered. For those unfamiliar with the device, it’s essentially a mathematical model of a hypothetical computer that manipulates symbols on a tape to perform computations.
This LEGO version boasts 4 (2²) possible symbols and 8 (2³) possible states, so in all, 32 possible symbol-state combinations. Each instruction features 7 bits (3 for the state, 2 for the symbol, 1 for moving left/right and 1 for stopping), so the “source code” takes 7*32 = 224 bits or 14 bytes. In other words, you can make 2^224 ≈ 2.69*10⁶⁷ programs. Most importantly, it connects all the functions to a single input, so you won’t need an electric motor. If you love this set, vote on it here.

The biggest disadvantage of the model is that it has ~2900 parts and barely fits of Lego IDEAS’ limit of 3000 parts. However, a lot of them are functional (i.e. part of the mechanism) or used to make the framework more sturdy because the mechanism is very precise and needs good support,” said its creator.
