Turing Complete/Binary Racer

This level is special in that it's a minigame instead of the usual circuit construction.

The goal of the minigame is to convert decimal numbers to binary while under time pressure.

Note that you can use the number keys above the letters on your keyboard instead of having to click the buttons. Use space to submit your answer.

Fast strategy
A fast strategy is to set the bit representing the highest value that doesn't overflow the target value. Keep doing this and you will hit the target value in no time.

An example:
The target value is 43. The first bit to set is 32. Next possible bit is for 16, but setting it will overflow. Continue to the bit for 8 instead. That makes 40. Set the two remaining bits to reach 43.
