I initially had an idea to implement an RGBW LED color controller in hardware, but I only had access to an FPGA along with free tools (though not necessarily open-source). Later, while participating in the ETHZ Summer School in Zurich, I discovered how it's possible, even for individual contributors, to affordably create an IC. At … Continue reading RGBW Controller ASIC, part 1 – An FPGA design forged into an ASIC
