Hi, I detected a lot of bad connections in the eagle schematic, for example T7 base is not connected to T8 base:


And in the shift registers, for example, pin 10 needs 5V, but is not connected:

The complete list of erros:

• T7 base not connected to T8
• T11 collector is not connected to LSP6
• IC 4,3,2 pin 10 not connected to 5V
