Recently I found plugin for CadSoft Eagle PCB software. Together with freeware ray-tracing software POV-Ray it produces 3D images of PCB boards. It looks like nice illustrations for PCB assemblage instructions. You can see how your board must look like. Also, you can see proper colors of resistors…
Thermoregulated fan control board.
3D library is not full. So these generated boards are missing of components. In this image, you can see, that one power transistor and trimmer are missing.
In this image, lots of components are missing.
This is high voltage generator board. Can be used to shock people or start welding arc.
Here you can see ray-traced image and real photo:
Switch power supply with Top-switch chip.
One more pair:
