A small line buffer for driving ws2801 LED strip from the SPI output of the raspberry. According to the datasheet of the WS2801 the data lines require 0.8*Vdd (= 4V for 5V led strings) for an input voltage to be considered as a high bit and the output of the RPI´s SPI is only 3.3 volt. Connections: 5volt dc jack in - USB-a out to power the pie or * :)
I use it for ambi-light / hyperion
