FPGA-based FOC for 6-phase BLDC

FPGA-based FOC for 6-phase BLDC

Power-Electronics
12 May 2025 Comments
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.

Replacing Viessmann oil-heater with DIY Arduino-Controller

Replacing Viessmann oil-heater with DIY Arduino-Controller

Programming
05 May 2025 Comments
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.

Recycling of old ThermoMix-Reluctance-Motor

Recycling of old ThermoMix-Reluctance-Motor

Disposing of defective appliances is common practice and repairing them is often uneconomical. However, there are often still very useful components in such devices. I took a closer look at a Thermomix and found a nice motor control unit.

Developing Retro-Softwares for OS/2 using Sibyl

Developing Retro-Softwares for OS/2 using Sibyl

Programming
21 April 2025 Comments
In the last blog-post I discussed developing retro-apps for Windows that can be run under OS/2 using the WLO toolset from Microsoft. But what about native coding under OS/2 directly?

Developing Retro-GUI for Win3.11 (Delphi 1) and OS/2 (Visual C++)

Developing Retro-GUI for Win3.11 (Delphi 1) and OS/2 (Visual C++)

Programming
14 April 2025 Comments
Retrocomputing with real hardware is a very nice way to understand how modern computers have learned to run and talk. I developed some GUI for OS/2 Warp 3.0 and Windows 3.11 to control some of my microcontroller-projects.

FPGA-based Audio-over-IP

FPGA-based Audio-over-IP

FPGA
07 April 2025 Comments
Ethernet on Microcontrollers is available without problems: using FreeRTOS or the Arduino-libs is always a good start. But for FPGAs? I was shocked how expensive Ethernet is for FPGAs - but I found a good solution...

FPGA-Audiomixer: IIR-filter for EQs

FPGA-Audiomixer: IIR-filter for EQs

FPGA
31 March 2025 Comments
Without the possibility to adjust the volume of individual frequency bands within an audio signal, modern audio would not sound the same. Today I'd like to show how I've implemented a EQ within my FPGA audio-mixer.

23 March 2025 Comments
In this video I'm testing the DIY Expansion-Card for the Behringer X32 audio-mixing-console with the Room-EQ-Wizard-Software and I'm showing the new workflow using XTouch-Controllers and more things.

17 March 2025 Comments
Implementing an audio-compression-algorithm in pure logic is a bit challenging as it uses a division. Time for some deep-diving into audio DSP with VHDL.
