In part 2 of this series I will show my progress on developing a DIY PCI Card using Alteras FLEX10K FPGAs.

Motorcontrollers are everywhere, cheap and reliable, but building a field-oriented control (FOC) from scratch to understand the details is a nice challenge. So I accepted the challenge and implemented a full-featured FOC within an FPGA.

Spare parts for Viessmann-controls are quite expensive. As the control of our oil-heater has broken down, I searched for a replacement but in the end I developed a full replacement with MQTT and connection to NodeRED.
