I'm sure it's nothing new but I've been noticing alot of 3D renderings of printed circuit boards lately so I decided to find out if there's a way for me to do it with my Eagle PCB boards. After a bit of searching I found a free ULP for Eagle that allows you to create pov files for a program called POV-Ray. POV-Ray allows you to render 3D graphics with stunning quality and is free. In about a half hour I was able to download and install the ULP's, POV-Ray, and create a top and bottom of one of my simple circuit boards.
The board I rendered is a breakout board I created for my Teensy 3.0 microcontroller (which is pretty awesome by the way). I needed a 16 channel multiplexer (MUX) for a project I was working on and needed to make it fairly quick so I decided to make it at home instead of using OSH Park. I had some 74HC4067 IC's in the DIP24 package so I made up a schematic in Eagle, created a PCB then etched a board. I also have a dual layer PCB version on OSH Park you can buy and assemble yourself. If you use the optional pull-down resistor this breakout will allow you to multiplex 16 signals to 1, or 1 to 16. The signals can be analog voltages or digital logic signals and the breakout can operate using a supply voltage between 2 and 6 volts. The biggest advantage to this breakout is that it can give you the ability to have 16 inputs and use only 5 pins on your microcontroller!
And, here is the actual working prototype single layer board. It's not as pretty as the 3D rendering but close.
Finally, here is the dual layer board available on OSH Park.
