Profile Information

About Me:
I work on FPGAs and related circuitry / code for DSP [RADAR and EO/IR sub-systems] and VHDL, C++, Java, Mobile development. Corporate recruitment is my day job.

Extracurricular: Bitcoining, Experimenting with GaN crystal growth methodologies and sensor fusion, Developing novel apparatus for flight control surfaces and landing gear
Please tell us a bit about your UAV interest
I don't recall if it was Star Wars, Captain Power, or Flight of the Navigator that sparked my fascination & love affair with aerospace & automation. Drones complete me.

"wow, 20Mhz of bandwidth and half duplex?, it could be the next opensource control+telemetry+digitalvideo by one only antenna?"

HackRF PortaPack - ARM Cortex software defined radio

Very cool application using the excellent HackRF platform demoed at Defcon.From HackADay:What do you get when you combine one of the best (and certainly one of the best for the price) software defined radios with the user interface of a 10-year-old iPod? The HackRF PortaPack, developed by [Jared Boone], and demonstrated at DEFCON last…See More

Reverse Engineering RC Toys Using RaspberryPi

Very cool project using RasPi as a transmitter for controlling RC toys.  The dev employed an impressive brute-force method [script + webcam] to identify command codes.From HackADay:  An interesting trick you can do with a a fast CPU and a GPIO pin mapped directly to memory is an FM transmitter. Just toggle a pin…See More

"Hi Shannon, that conversion from Spectrum is really nice, the ramp soak PID controllers for only $85.00 from the company linked (Lightobject) are a great deal and they have the other stuff you might need as well. Basically a no brainer at all."

Gary McCray commented on Shannon Morrisey's blog post DIY FPGA Reflow Oven
"This is an interesting exercise if what you want to do is learn about FPGAs and have a spare FPGA board lying around. But if you just want to build a simple reflow oven almost any cheap micro dev board will work fine. You need a micro board with a…"

Has Flight Automation Gone Too Far?

Interesting read on the limits and human factors complicating flight automation.  I contend that all issues are solved with better sensors & processing ability/reliability.
