About Us

The Practical Use of Technology in the Real World

Integrating Technology in Life

We are creative integrators of  hardware, software, electronic components, sensors and communications technology to build systems for Controlled Environment Agriculture (CEA) and other real world data, control, monitor applications.

Our team brings several lifetimes of experience in agriculture, technology, industrial design, electronics, computer information science (CIS), construction, and general business to the table. We were repairing television sets and guitar amps in the 1970's.  We were programming and building computers in the 70's and 80's.  We have worked in technology, networking, programming, telemetry, SCADA, logistics, construction, industrial design and engineering, business development and agriculture.  We are old, knowledgeable and experienced.

Why the Name Gray Box Technology

We are supporters of Open and Shared Technology.  We have found an existence between open source and completely closed commercial.

A Black Box refers to a closed system.  Inputs give Outputs with no awareness of what happens in the system.  A White Box would be a totally open system.

We are not totally open, as in open source, open hardware.  We are somewhere in the middle.  We use a number of open source/hardware components, while keeping our software proprietary.  We have chosen this approach to allow our customers to maintain or repair our products.  Sustainability and the Customer’s Right to Repair is key to our design philosophy.
