I am trying to cook up a permanently installed USB NeoPixel controller. After I got the board layered out I pulled this render. The attached image is actually cropped from the actual output, since the original output, rendered on a 4K monitor, is way too large for the forum software.
The single frame 4K raytracing render is produced on an Intel Xeon E3-1231v3 processor, overclocked to 3.51GHz base clock speed, and it took me 113 seconds.
The hardware itself is a NeoPixel controller based on an Arduino-like platform. The main microcontroller is an ATtiny841 running at 16MHz. The USB interface is implemented using a Holtek HT42B534-1 in SOP-10 package.
KiCad 5.0 on 4K monitor seems a little bit too demanding for the GTX 1060 3GB graphics currently in my machine. I wonder if the AMD RX 580 with its 8GB VRAM, or some new card from nVidia, would help.
