We've contributed to the hardware, software, project and/or system engineering on many large project-teams. Some projects were expansive and complex; some were clever and innovative; and some were industrialized into mass-production of hundreds of thousands of units.
However, our specialty is designing the interdisciplinary entirety of products that feature an embedded microcontroller with surrounding digital and analog circuitry to interface to other devices and/or to a larger system. Control information is exchanged over IR (infrared), RS232/RS485, USB, Ethernet or some similar or derivative serial interface. Examples include:
