QR code generator

A QR Code Encoder

This Redstone machine can generate a QR code.
In the center, there is a keyboard where you can input your word. It can be up to 32 characters long. On the left side, there are 32 lamps that symbolically display how many characters have already been written into the memory.
To the left, there is a red button that allows you to clear the contents of the memory.
On the right, there are 4 buttons (cyan concrete) to define the encryption depth. For large inputs, only the lower level is possible.
After entering your word, you can press the orange button on the right to start the calculation. After 6080 ticks, or 5 minutes and 4 seconds, the generated QR code will appear on the screen.
For some fun, you can use the 8 green buttons on the left to change the masking. The content does not change, but the appearance of the QR code does.
Make sure that the entire Redstone area is loaded. Use /forceload if necessary.
