This is the controller board for a 3D printer filament drying/storage box. It uses a 3d printer bed heater to heat the box and a thermoelectric cooling element to dehumidify the air inside the box. The board also has connectors for the bed heater thermistor, two I2C buses for temperature/humidity sensors, 3 fan connectors and a SparkFun Microview display. Remote communication is provided by an Xbee radio. Everything is controlled by an Atmega 328P.

Version 2 of my Arduino Due shield for G2 CNC controller. This is when using Clearpath servos instead of steppers. Uses a tag-on Arduino Pro Mini for monitoring the Clearpath status and triggering a feedhold if any of the servos fault. Outputs motor torque and fault to LEDs. Only 3 limit switch inputs, but now with low-pass filters. No on-board power, uses raw input voltage from Arduino.

Arduino Due shield for TinyG “G2” CNC motion controller. Breaks out 6 axis stepper outputs (for use with Geckodrive stepper drivers), spindle control, a switchable coolant output, limit switch inputs, and a general 12V power. Also has an on-board switching regulator to power the Arduino from 48V motor voltage power supply.
