This project uses a lot of materials, so its best to have them all in one list. To build this completely, you will need
• 192 LEDs (LEDs can fail or be fried easily, so I recommend getting 200 even)
• 3 x 74HC595 shift registers
• 24 resistors (Use this to get the values you need (http://led.linear1.org/1led.wiz
), you will have to know your LEDs forward voltage and current, as well as what you are supplying it with (in the case of arduino it is usually 5v sourced))
• 8 x 1k resistors
• 8 x 2N3904 transistors
• 1 x 4017 decade counter
• 1 x Arduino board or Atmega 328 chip. Make sure you have the tools to program it if you just have the chip
• Wire (lots of it!). I went through probably 50ft of wire making this. At least 50ft, if not more...
(A side note on the wire, solid core wire in a thin gauge (22-26ish), is very helpful when building this, because we will strip most of the coating of to solder it. If you can find some uncoated wire, that will help for most of the building process, and save you lots of time stripping wire)
• Tracing (sketching) paper. You can also use wax paper or parchment paper if you cannot find tracing paper
• Glue. I just used white Elmers glue and it worked great
• A foamboard panel (36 in long). I used this
board from walmart, its just the right size. They had it in single-piece packages and were in the school supplies. Alternatively, you can use cardboard, or a similar type of board.
• Electrical tape (optional, but really useful)
Shameless plug- I get most of my parts from taydaelectronics.com- great store (especially for students on a budget :D), but shipping takes a while (~10 days). If you want to get it quick, I recommend Digikey or Mouser electronics. Great stores, and digikey usually gets to me in 2 days.
