Raspberry pi & Arduino<\/h1>\n

The next step was to design the perspex board which will mount the raspberry pi, which will be our media player, and the arduino which will control the back light, power and sensors (more on this at a later date).<\/p>\n

As with all of these boards, we began with a vector design:<\/p>\n

\"Vector<\/a>

Vector Graphics for the Raspberry Pi and Arduino perspex. The different colours represent different depths of raster engraving.<\/p><\/div>\n

The different colours represent different depths of raster engraving. From our earlier experiments in Pt.1<\/a>, we could quickly decide these.\u00a0I took a quick snap of the settings here:<\/p>\n \n\t\t

Power Supply<\/h1>\n

For safety reasons the power supply PCB had to be mounted in an enclosure which protected people with wondering fingers! Here is the vector design for the box:<\/p>\n
