Solagen Wireless Monitor
Completed Mar 04, 2012
An existing battery monitoring platform, the TM2025 from Bogart Engineering, was modified to allow the output to be extended wirelessly to a new monitor display. The monitor allows displaying such parameters as battery voltage, amps, percent charged, and more on a small LCD. The radios that comprise the wireless link are IEEE 802.15.4 type radios (RF Engines) from Synapse.
Add Wireless interface to Arduino-Based sun tracker
Completed Nov 06, 2011
The prototype heliostat completed in the previous project was retrofitted to add wireless connectivity for remote access. The design was created with 802.15.4 radios from Synapse. Using a Synapse RF Engine, the Arduino was effectively bridged onto the wireless network by a connected serial interface (between the RF Engine and Arduino). A computer application was provided to easily configure and control the remote node, by connecting through Synapse's USB-based SNAP Stick module. This project was tested with a single node target, but was intended to scale to support several heliostat targets.
Build Arduino-Based sun tracker, from plans and code
Completed October 25, 2011
A protoype heliostat was built and tested based on a previous design. A heliostat is a device that is able to track the sun as it moves relative to the Earth. The project involved fabrication and selection of the aluminum components as well as modifications to the exisitng Arduino code.
A small embeddable USB CDC driver for LPC1768
Completed July 31, 2011
The goal of this project was to present a USB CDC device using the NXP LPC1768. The LPC1768 is an ARM Cortex microntroller with integrated peripherals suchs as USB and serial UARTs. This device presented a virtual COM port to pass serial data from the USB port to the ARM's serial UART. The firmware was bulit using the Rowley Crossworks for ARM IDE.
