Using Python For Creating Hardware To Record FOSS Conferences
summary
Built a production HDMI capture system that turns presenter video into a webcam stream and debug serial data, implemented as an HDMI-to-USB box using FPGA logic generated from Python HDL (Migen/MiSoC), a soft CPU (LM32/OpenRISC), and a host bridge for rapid iteration. The Python-based redesign reproduces prior Verilog/VHDL features in four weeks instead of years, runs at PyCon AU and other conferences, and records talks successfully in production.
