Automated imaging system for protein crystallography
Electrical Engineering/Mechanical Engineering/Project and Shop Management
Where: Formulatrix, Waltham Massachusetts
Project life cycle: Helped grow a startup software company into
a Biotech/Pharma robotics company. Planned, designed, built and
manufactured the company's first mechanical product, an automated
imaging system for protein crystallography, and oversaw the growth
of the Engineering and Manufacturing part of the company from one
to six people. Set up and managed an in-house CNC machine shop to
build both prototype and production parts. Managed the production
builds of initial product offerings ($1.2 million). This included
the machining of most parts in the system. In addition to designing
much of the mechanical systems for the robots, I also did all of
the electrical design including PCB layout and setting up of an
in house SMT reflow process.
Electronics package for mobile multi-axis robot
Electrical Engineering, Project Management, Product Design
Where: PRI Automation, Billerica Massachusetts
Project life cycle: Designed the electronics for a multi axis robot
that traveled on an overhead track. The electronics package I designed
included switching power supplies, programmable logic, embedded
microprocessors, optical and ultrasonic sensors, motors, encoders,
motor amplifiers, motion controllers, and RF and IR Communications.
I condensed the circuits, fit them in a very small package, and
integrated them into the robot. I spent much time in the lab debugging
both the mechanical and electrical operation of the robot. I was
the lead in making the robot work. I also conceptualized and implemented
several major architectural changes. One of these changes involved
redirecting the project away from an expensive and complicated inductively
powered track to a much simpler more effective design that used
Ultra-Capacitors (1200 Farad Capacitors) that could be charged at
certain locations on the track, and used to replace the batteries
that power the robot. This idea halted a proposed 2 million-dollar,
2 year R&D effort, and replaced it with a 100,000 dollar 6 month
effort. In addition the total system cost was greatly reduced, projecting
savings of several million dollars per job. Completed in Nov. 2001.
Rotating LED light sculpture
Services: Electrical Engineering/Mechanical Engineering/Programming
Where: Displayed at BurningMan 2005
Project life cycle: Designed and built 9' diameter rotating super-bright
LED display programmed with color animations. To refine a cost-effective,
workable design in a short time, worked with lighting expert Carl
Gruesz, whose work this year included lighting for official BurningMan
installations. A future version of this piece
is planned to display video.
Autonomous Underwater Vehicle- Interface board and
5KW Lithium Ion Battery monitor and charger
Skills used: Electrical Engineering
Where: Bluefin Robotics, Cambridge Massachusetts
Project life cycle: Designed built and installed an interface board
for an AUV (Autonomous Underwater Vehicle). This involved determining
the requirements of all associated electronics, designing the interface
circuitry, and performing all schematic capture and PCB layout.
Also contributed to the design of its 5KW
Lithium Ion Battery monitor and charger. Completed in 2002.
Microprocessor-based fire alarm panels and switch
mode power supplies for fire alarm systems
Services: Hardware Engineering, Product Design
Where: Notifier/Firelite Alarms, Northford Connecticut
Project life cycle: Designed microprocessor-based fire alarm panels
and switch mode power supplies for fire alarm systems. Cooperated
with marketing to come up with new products and product specifications.
Engineered panels and power supplies according to design specifications.
Created schematic drawings with Orcad Capture. Coordinated with
Production to build both prototypes and finished product. Tested
and proved prototype designs. Worked with listing agencies (UL,
ULC, FM, and FCC) to obtain product listings and approvals. Wrote
the company's first Windows-based panel-programming utilities, using
Visual Basic linked to Microsoft Access databases. Proposed and
set up the engineering departments first LAN. Completed in Oct.
Large facility management control systems
Services: Systems Application Engineering
Where: Johnson Controls Inc., Hartford Connecticut
Project life cycle: Designed large facility management control
systems, including the controls for Foxwoods Casino. Integrated
microprocessor based controllers, sensors, and actuators with HVAC
equipment to sequence it according to control specifications. Networked
buildings and complexes' HVAC equipment to allow for central monitoring
and control. Used AutoCAD to create control drawings for submittals
and field use. Wrote software to run individual controllers and
facility wide control algorithms. Designed custom graphical user
interfaces for central PC control. Provided support to the field
during installation and check out. 1992-1997.
