Bullet-Intercepting Lightweight Body Armor

Body Armor that fires an aluminum slug into an incoming bullet's center-of-percussion. The bullet shatters into fragments if you hit it right, and the fragments are easier to stop in Kevlar as a result.

Thermal Infrared Camouflage

For people and vehicles ... An invention well ahead of its time. The U.S. Military doesn't need it because they think nobody will ever be using FLIRs (Thermal Imagers) against them. They may be right ...

iSTAR/MAV

Ducted-fan UAV's made for U.S.Army and DARPA. Allied Aerospace is now Triumph Aerospace, I think. ANYWAY, we flew at every test, on time, performed as advertised. Government told us: "So long, and thanks for all the fish..."

Aviation Crew Trainer

A shoulder-fired MANPADS simulator. Replicates the UV and IR signature of a missile launch

X-43A Project Engineer

I was once, briefly, Integration Engineer for the third X-43A Hyper-X aircraft. I was really hired for the X-43C program. The X-43A eventually flew Mach 9.8 or so. http://en.wikipedia.org/wiki/File:X43a2_nasa_scramjet.jpg

BORS

Designed the Barrett Optical Ranging System (BORS). A ballistic computer that gathers atmospheric data and riflescope data for long range riflery. It uses a PIC microcontroller. https://barrett.net/optics/bors

UAV digital fuel gauge

Designed and built a capacitive-stick gas gauge that measures fuel remaining in UAV gas tanks down to 1/100 th total tank volume. Uses 555-timer and an Arduino Nano. OLED readout or RS-232 serial stream to flight computer.

Laser Echo

Built a device for testing laser rangefinders that detects rangefinder pulse (1.06 microns wavelength), then emits a corresponding pulse back to the rangefinder equivalent to a TOF for one Kilometer (selectable). A PIC16F737 does all this.

UAV tracker

Built a 3DOF flight table and electronics that tracks UAV's (drones) using only their GPS streaming data (and the GPS coordinates of the table). HDTV camera provides view of UAV in flight. Camera mount and cover 3D printed.

mendel

built my own reprap mendel from scratch
