I have been working on refining my PCB skills. I came up with a board idea, did the schematic, laid out and routed the board, ordered the PCB and parts plus a stencil, stenciled the paste, placed the parts , reflowed the board, powered it up…. and it worked perfectly! The board is just something fun to play with.. it is a 4 processor arduino board with 4 ATMega328PBs in an SPI ring network ( since the 328PB has two SPIs).

I made a small video of the board process for those inclined to learn: https://youtu.be/V1xXG8YTmK4

.. and a few pictures post Hawaii. Most of the exterior walls on the third floor are now done. Interior walls next, then some shear wall work, then the deck, then the two story tall great room walls.

This is kind of a neat little development board. Raspberry Pi sized, quad-core ARM plus 128 NVidia Maxwell CUDA cores. 472 GFlops in a very small package, perfect for machine learning camera image recognition. I’m thinking about putting one of these with every camera in my new house so I can have continuous object recognition feeding into a central AI.
