    8X8X8 3D RGB LED Cube

    Here is apicture of my past work.I havestarted building a 8x8x8 RGB cube using the PCB and bridge-board from SuperTech-IT.For building the panels I have used the building principle from K.Michalsky/Steve Manley using most of their techniques (see his video under https://www.youtube.com/watch?v=8vaaau4P1kE).As most RGB cube builds “suffer” under the time demanding preparation andbending of the LEDs I have built a dedicated bending tool resulting in a finaltime demand of 45 seconds per LED for the complete preparation process (bendingof the legs of the leds, cutting to right length and bending of the bail). So,for the 512 LED for an 8x8x8 RGB Cube it took less than 6 hours. The finalsoldering of the panels and installation on the PCB took another hour / panel.I have decided to...see more »Here is apicture of my past work.I havestarted building a 8x8x8 RGB cube using the PCB and bridge-board from SuperTech-IT.For building the panels I have used the building principle from K.Michalsky/Steve Manley using most of their techniques (see his video under https://www.youtube.com/watch?v=8vaaau4P1kE).As most RGB cube builds “suffer” under the time demanding preparation andbending of the LEDs I have built a dedicated bending tool resulting in a finaltime demand of 45 seconds per LED for the complete preparation process (bendingof the legs of the leds, cutting to right length and bending of the bail). So,for the 512 LED for an 8x8x8 RGB Cube it took less than 6 hours. The finalsoldering of the panels and installation on the PCB took another hour / panel.I have decided to build the cubes “upside down” – meaning the soldering facesare facing to the LEDs making the chips in its sockets easy to assess on theunderside. To control the cube I am using the ChipKit uC32 and theSuper_Big_Show programmed by Doug Domke. But the 8x8x8 RGB cube was just the startingpoint – next I extended an 8x8x8 cube to an 8x8x16 “pillar” by using and an additional board with a 74HCT541 and 8 BD136 PNPtransistor to drive layers 9-16. To do so I only had to use additional outputpins of the uC32 to connect to the second 74HCT541 on my custom board. Tochange the routines in the background of Doug Domke´s Super_Big_Show was a bitchallenging for me as a beginner in arduino programming but finally Iunderstood the programming principle and was able to adopt most animations theextended possibilities of my “pillar”. But the winter as long – so there wasthe desire to have an even bigger led “sculpture” so I decided to build a16x8x16 LED cuboid based on 2 of SuperTech-IT´s PCB´s. This cuboid has now 2096 RGB LEDs and is stillrunning on a single uC32 arduino with adopted animations of Doug Domke´sSuper_Big_Show.
