About Me:
BS, MS Aerospace Engineering. Been playing with robotics and RC airplanes for a few years. Also, I've done some work on autonomous computer vision systems and target localization on UAVs.

"That looks pretty nice, Have you thought about displaying the aircraft location on an aerial map?"
If you're about to deal with interested parties overseas, consider this:Maryland woman charged with illegal export of miniature aircraft controls to ChinaWASHINGTON (AP) — A Maryland woman was charged Friday with exporting miniature controls for…
"The benefit would be that you'd free up that part of the spectrum. Autopilots like the Piccolo autopilot by Cloud Cap Technology integrate data and RC on the 900 MHz band. The remote control plugs right into the base station."
"Marty, the GPS L1 frequency is 1575.42 MHz, so it's closer to 900 MHz than 2.4 Ghz, but not by a whole lot. All electronic devices are going to emit some electromagnetic radiation. It's difficult to predict what is going to work. You might have…"
"I was hoping to benchmark them last week. I ordered a pair of the $42 RPSMA XBee-Pro 900s on the 13th. Maybe they'll arrive this week."
"The TinyAVR is the AT45 chip. It's just a small microcontroller, like the ATMega168, that needs to be programmed. The 6 pin header and that contraption is used to program the TinyAVR chip."
"Brian,
I think this is what you're looking for: ATAVRISP2-ND"

"This isn't quite as intimidating as a Rocket Propelled Chainsaw"
"I hope no older folks in London read to much into this post.
Anyway, I imagine there would be stabilization issues with any pulse jet powered aircraft using thermopiles for stabilization. The exhaust is pretty hot.
Here's an impressive video of an…"

"This would be great! Even $10/unit would be a significant improvement. I'll believe it when I see it Q3 this year."
"A lot of universities are using SIG Kadet Senior aircraft because of the relatively large internal space and 7 pound payload capacity (with a bit of modification). If you're looking for long endurance or to carry a lot of electronics, this is a good…"
"Be careful with that gyro. It has a max rate of 75 degrees/sec (that's a slow 1 revolution per 4.61 seconds). This might be good enough for your application, but it could get saturated in most R/C airplanes."
"Jack,
The Propeller Tool doesn't really work well under Linux but you might be able read the .spin files (some have tried). It's rather unfortunate. Also, you can see the SD card schematic for the Propeller"

"This looks really good, Paul. And all with just one cog.
I can't wait to see the second half. Building waypoints in GE and dropping it on the SD card would be really convenient."

"Nalgene bottles are about the most indestructible thing I own and you guys broke one. Awesome!
Try a stainless steel bottle."
