That success made me like this page a lot and also made me want to make guides like that one, well documented and properly explained, enabling people to make cool things, at first without them knowing how they work, and from there, from a working piece, start learning and understanding how it works.
note: the last 2 videos are not from my cube, but it works in the same way and gives the same result.
Step 1: Materials
- 1x Atmega328 (With arduino Optiboot bootloader)
- 3x TLC5940
- 4x P-Channel MOSFETs
- 3x 4K7 Resistors
- 3x 16 pin Male and Female headers
- 1x 4 pin Male and female header
- 1x 28pin IC socket
- 1x 1000uf 10v capacitor
- 1x 0.1 uf ceramic capacitor
- 2x 22pf capacitors
- 1x 16Mhz crystal oscillator
- 64x RGB common ANODE LEDs (it is very important that you check your LEDs are common ANODE, or else, the cube won't work!!)
- a LOT of Solder!
for more advanced functions;
- 3x 8k2 resistors for optional, low power mode.
- 3x 3pin male headers for jumper selection of the power mode
- 3x jumpers for selecting the power usage/brightness setting
- 2+x 64KB EEPROMs for storing custom animations
- 1x DIP switch for selecting different modes (random, serial, music responsive, random2, custom animations, etc.)
- 2x MSGEQ7 chips for audio analyzing and music response.
- Black paint
- An Arduino to use as a USB to Serial converter for programming
- An USBTinyISP if your Atmega chip is not pre-Bootloaded
- A Multimeter for troubleshooting and checking connections
- Some way of cutting PCBs, I used a Circular Saw, but you can use whatever you have in hand.
- Diagonal cutters
- A Sharpie or any kind of marker
- A Drill/Drillpress
- A Cutter or Xacto knife
