About me: I have developed electronic products for the consumer and research industry, including educational toys, walking robots, and balloon weather systems. The majority of my work experience has been in small tech startups where I was responsible for all phases of development from conception to manufacturing including hands-on prototyping, in both hardware and firmware development. I can help in electronics/embedded engineering, designing and prototyping circuit boards, coding firmware for microcontrollers and manufacturing support. Please see below some of my recent projects. |

CUBELETS Cubelets is an educational robotic toy from Modular Robotics. Hundreds of different robots with unique behaviours can be built by assembling the various sensor, think, and actuator blocks together. I am currently the lead Electronics Engineer on the team and have designed all the electronics and firmware for the robot kit. Challenges in this project involve designing the communication protocol between blocks via a single wire, handshaking, keeping track of connected blocks, and developing a data diffusion algorithm along a robot construction. The various designs involve Lithium Polymer battery protection and charging, motor control, bluetooth, and communication protocols. |

MOSS Moss is the second product line of Modular Robotics and is a more advanced robotic building kit for educators and hobbyists. I was involved in the electronics design of this consumer product from initial conception to manufacturing, including hands-on prototyping. I am currently working on supporting the Moss production line by desgining various bed-of-nails jigs to do circuit board testing. |

TILDAE (Turbulence and Intermittency Long Duration Atmospheric Experiment) TILDAE is an atmospheric probe sent on NASA's GRIPS ballon mission to study turbulence in the upper stratosphere. I designed and prototyped the main circuit board that is responsible for gathering wind data from a sonic anemometer, storing the data in SD cards and communicating results to the main flight computer for telemetric transmission back to earth. |

AMORPHOUS ROBOTS An amorphous robot is one that can change its shape or configuration. The IcoTens (left) and Soft Modular (right) Robots from the Cornell Creative Machines Lab change their shape by varying the tension in a structure of cable and rods. I designed a networked system of motor controllers that enable those robots to not only alter their structure but also move. Each circuit board receives instructions wirelessly from a PC and sends optical encoder and strain gauge sensor data back to the host. Here is the Electrical Schematic for each motor. |

PROGRAMMABLE MATTER Imagine, from the click of a button, disassembling an object and re-assembling it into another object of a different form and serving a different purpose. At the Cornell Creative Machines Lab, we explored Programmable Matter in the robotic field by re-arranging intelligent cubes in a fluid. I was involved in the design and building of the electronics of the intelligent cubes. Each cube knows its orientation and contact face. Challenging aspects in the design of these circuit boards is to ensure the bonding of the correct electrical contacts with an adjacent cube. |
