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, and building and sharing new things. I strive to always improve and expand upon my technical, non-technical and interpersonal skills.

I work as an embedded systems engineer at Crystal Fountains Inc. Crystal Fountains is an international leader in the innovation, design, and manufacturing of premium architectural water features. Working in the New Product Engineering department, I design and develop electronics and firmware for fountain sequencing products such as LED lights, motors, and DMX/RDM equipment. I have also traveled abroad to Finland, Spain and the U.S.A. to provide specialized electrical and electronics support during the commissioning of new fountains.

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.
