As per the schematic included with the files solder the electronic components in the pcb. Parts needed are: 9-SN74HC595 shift registers; 16-2n2222 transistors; 512-5mm LED’s; 66-220 ohm resistor; 1-10k ohm resistor; 2-5mm indicator LED’s; 1-12mm panel mount pushbutton; a couple meters of hookup wire; 45 yards of silver plated copper wire (jewelry wire); 5v power supply.
In about a week or so I will be making another two of these, of which I will try to document the process much better so that it is easy to replicate)
