Electronics Resume

Long embedded digital systems experience, gained in a breadth of target industries, has resulted in an electronics design expertise applicable to any digital design challenge.

Designed, laid out, tested, reviewed, and manufactured a number of electronic circuit boards. Several activities were classified and most remain proprietary; in respect for my clients, summaries only are listed here:
- Timing, clocking, and interface conversion boards
- RF upconverter, downconverter, and sampling boards
- Remote sensor data acquisition boards, including position sensing
- Boards and boxes for running automated tests on manufactured devices
- Very compact boards, reducing component count to minimum, to fit in tiny enclosures
- High-power AC switching systems and DC motor drives
- Designed, assembled, and tested a successful prototype vein-identification image processing device.

Architected, led the design team for, and tested the SMARTBus Core Electronics Block: a single small board which performs power management, computation, data interface, self-healing, networking, and EDAC functions for spacecraft subsystems. Integrated two microprocessors, an FPGA, power and interface electronics; multiple CEBs automatically networked to perform larger tasks.
In three weeks, took over, redesigned, and reimplemented the digital section of a radar transponder which had been entirely nonfunctional. Upon delivery, all digital functions performed per or better than specification. Vastly reduced board size and complexity, while increasing design flexibility.
Solely designed, implemented, tested, and integrated the Bitsy single-board-spacecraft command and data handling system. This was an FPGA-based, extremely low power, robust device which performed all the digital, analog, and serial interfaces of a complete microspacecraft, oversaw vehicle health, and commanded primary and backup power systems.

Implemented the Link layer of a high speed, radiation hardened P1394 Firewire � PCI bridge ASIC for a classified Navy satellite. Brought the device from specification through design and simulation to fabrication. Design process paced and moved with the P1394 definition, still in development at the time.
