SNAFU box

A SNAFU box project by Bertho of Vagrearg: SNAFU Box consists of 24 LED strips (12V passive type) of varying size, which are controlled by a set of 74HC595 shift-registers and a transistor driver for each strip and RGB channel. The LED strips are used to backlight the lettering of the box. An additional three 74HC595 […]

LED strip testing with Bus Pirate

Drew tested out some addressable RGB LEDs he bought during Hacker Camp, using a Bus Pirate.    Via Shenzhen_hacker_hole WeChat group. The LDP6803 uses SPI for communication. A power supply and a Bus Pirate and I was able to change colors without code. The chip uses a 7bit encoding of colors so setting individual colors can’t […]

Free PCB Sunday: USB RGB color changer

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype. This is a USB controlled RGB color changing light. Someone made some minor modifications to […]
