Innovative solutions designed and built by Nessie Circuits.
A development platform for energy-harvesting devices with four stackable boards. The SDK includes a battery-free runtime environment, device drivers, two network protocols, and example applications, ranging from basic "Hello World" to hotword detection.
A system designed for replaying reproducible light traces. It features a BeagleBone with a custom cape that controls current through a high-power LED. The firmware retrieves light traces from an SD card or streamed via TCP/IP, adjusting the LED current at up to 1kHz.
An expansion shield that interfaces an STM32 Nucleo board with industrial manufacturing machinery. The board includes multiple isolated power supplies, an industrial Ethernet controller, and a variety of isolated communication interfaces.
Nessie Circuits was founded in 2021 by Dr.-Ing. Kai Geißdörfer, a renowned expert in energy-harvesting systems with over a decade of experience in designing, building, and programming low-power embedded IoT devices. Collaborating with partners and suppliers both locally in Berlin and globally, he ensures project success and customer satisfaction. Our customers include universities, research organizations, and companies worldwide.
