Part 11 in the PSU design series.
This time it’s the housing design based on the new Rev C schematic, and the secret reason behind the project!
The next video will follow with an overview of the Rev C schematic.

Dave recently implemented an Actel Ignoo Nano and Xilinx Spartan 3 FPGA into a design, so decided to share some rather random notes on how to implement the FPGA’s in this scenario.
From datasheet specs, traps for young players, global clocks, FPGA fabrics, core power supplies and decoupling, getting the schematic basics, JTAG and flash PROM interfaces and finally PCB fanout and routing of a tiny 0.4mm pitch BGA package.

Dave show you how to solder a small 3 axis accelerometer LGA surface mount chip “dead bug” style onto a microcontroller prototyping board.
This technique allows you to easily prototype projects using tiny SMD components designed only for reflow soldering.
