Tell us about yourself!
Pretty straight forward. However, I altered a few steps and added some for convenience as well as proper operation. First of all, I suggest you use 270 ohm transistors instead of 330 ohm which will make the LEDs light up a bit brighter. Furthermore, the wires need to be soldered to the opposite leads of each resistor instead of the lead to which the LED columns are to be soldered. In your drawings this was done incorrectly. However in the wiring scheme this was done correctly. Failing to do this properly may indeed still have the effect of lighting up the LEDs but this isn't guarenteed and may even cause the LEDs to burn out entirely as they require an interposed resistor in order to cope with the load caused by the electrical current.
Obviously I meant to say resistors instead of transistors.
