Inside a 3D LCD TV – Details and Laser Cutting Pt.2

Raspberry pi & Arduino

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).

As with all of these boards, we began with a vector design:

Vector Graphics for the Raspberry Pi and Arduino perspex. The different colours represent different depths of raster engraving.

Quick check of the design for size and layout:

The different colours represent different depths of raster engraving. From our earlier experiments in Pt.1, we could quickly decide these. I took a quick snap of the settings here:

Then onto the laser cutter:

Power Supply

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:

Back over to the laser cutter:

Holes for ventilation:

PCB raisers travel from back to front holding enclosure together:

Power supply output to mainboard and 3D processing board:
