What Should We Build Next?

me Hi! Iā€™m Michael Kafarowski. I have a passion for exploring new skills and ideas. I love taking things apart, learning how things work, building stuff and sharing ideas.

I work as an embedded systems engineer at Crystal Fountains Inc, an international leader in the design and manufacturing of premium architectural water features. I design and develop electronics and firmware for fountain sequencing products such as LED lights, motors, and DMX/RDM equipment.

You can check out what Iā€™m up to right now.

Featured Project: Marlin 200W+ BLDC Motor Driver (2024 | Crystal Fountains)

The Marlin BLDC Motor Driver powers the Crystal Fountains CFPDMX line of submersible pumps, built to realize stunning choreographed fountain shows with dynamic jet effects, extremely fast response times and stream heights up to 10 meters. I designed the electronics, which converts 24VDC power into three-phase AC power for the brushless motor in the pump. I also developed a DMX/RDM 'operating system' for the STM32 processor to control and monitor motor torque and speed, and a bootloader to allow reliable and safe field updates.
