About Us

Kea Sigma Delta is all about creating useful/fun things with technology, and helping others to do the same. It stems from the founder's (Hans de Ruiter) own interest in science, technology and building things himself. There's something strangely satisfying about turning the vision of a device or app that solves a problem (or achieves a goal), and making that vision a reality. It's truly magical to switch something on for the first time, and watch it do exactly what you designed it to do.

We have a definite focus on software, but are interested in computer hardware and technology in general.

About the Name

The Kea (Nestor notabilis) is an alpine parrot that is native to the South Island of New Zealand. With strong problem solving skills, and the ability to learn from one another, it is considered by scientists to be one of the most intelligent birds in the world. Thus, the Kea represents the intelligence in the software, systems, and products that we develop.

Sigma-Delta (or Delta-Sigma) modulation is one of the methods used in Analog to Digital Converters (ADCs) and (DACs). ADCs are essential for computer systems to read sensor data, while DACs fulfill an important role in driving motors, actuators and other devices. So, Sigma-Delta represents the link between the intelligence (Kea), and the real world.

Putting it back together, Kea Sigma Delta becomes "smart technology for the real world."
