Previous Page Next Page Build the CB280 Mini Proto-Board First, you will need to build a CB280 Mini Proto-Board.  Here’s the HOWTO on our wiki: CB280_Proto-Board_Solder_and_Assembly_HOWTO When you are done building it, you can follow the Light Orb Mods: First, get the 3 4.7K resistors soldered onto I/O labels P5, P6, P7, and to empty holes as shown here: Get one of your 2N3904 transistors and solder it on like shown here: Solder on 2 more transistors: Solder on 3 100 Ohm resistors to the right side of the resistors as shown here: You can connect one end of the resistors to the right pin of the transistors as shown here: Solder on your 4 Red LEDs in series from the 100 Ohm resistor: Solder on your 4 Green LEDs in series and your 4 Blue LEDs in series too: You can use one of the LEDs in series pins to connect to the other end of LEDs in series. So connect ground of LED row 1 to LED row 2 and connect ground of LED row 2 to LED row 3. Previous Page Next Page
