Project Portfolio

A selection of completed projects

Power Line Controls

IOT over power lines. A line of products developed at ARG to allow communications and control of lighting and equipment over existing power lines without the need for any new wires or wireless setup. This also  creates a secure airgapped private network decoupled from the internet or the cloud for security and reliability – especially useful for monitoring and control of critical infrastructure.

Cryo device controller

A microchip PIC24 based controller and power board. The controller has a RFID module, a LTE CAT1 modem, Stepper controller, LED controller, thermistor inputs, fan speed controller and a touch screen display. Firmware (embedded C) and software (C#) were developed for closed loop control of a treatment cycle. Server side code was developed for remote diagnostics using the LTE modem and AWS servers.

Multi Axis Brushless motor controller

A Performance Motion Devices MC58420 chipset based 4-axis brushless motor controller with on-board amplifiers (4A@24VDC), solenoid valve drivers and RS485 communications with a unique daisy chain architecture for stringing multiple boards together. Developed for a automatic multi channel pipetting machine used in the life sciences industry

Smart Thermostat

A microchip PIC24 based thermostat with LoRA, WiFi,  Bluetooth Low Energy and e-ink display including enclosure and overlay design. Developed for EPRI for a California Energy  project.
