Profile Information

About Me:
I work on FPGAs and related circuitry for DSP [RADAR and EO/IR sub-systems] also do some corporate recruiting
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.

"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."

"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…"

"What's the reason for using an FPGA here instead of a libc-compatible 8-bit microcontroller such as AVR? Other than "that's all I had lying around". More expensive, more difficult to program and debug..."

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