"Has anyone received a copy of the code or thesis paper? I still haven't... (rc@woollum.com)

Just curious."

"Peter, I'm interested in your thesis project. Can you send a copy to rc@woollum.com?

Thanks!"

"Hi Tim,

I was planning to implement the first three already. The current draw will be both reporting as well as automatic limiting to save the ESC from damage."

"Interesting point. I was thinking the value to the community was mostly in the I2C capabilities of the ESC. This can be further increased with additional software features.

What features (or IP) did you have in mind?"

"I agree and that would be how this was released. Open source is key! Of course it's AVR-based so if you know how to program AVR's you can program these ESC's. The ISP header is broken out so it's easily accessible as well."

"bGatti - I think you're absolutely correct! The only situation where this wouldn't work is at a very low motor RPM where each winding carries 100% load for several seconds (just an arbitrary example - the motor would have to be going VERY slow for…"

"Hi Tim,

That's what I'm planning on doing. There will be a QuadESC and a Single ESC, both using identical components and firmware.

bGatti,

Unfortunately it doesn't work this way. Brushless 3-phase motors only push (or pull) current through any…"

"Sorry - I didn't mean that the wiring doesn't weight much overall. I meant the difference of wiring when rotor-mounted ESC's are used vs. the wiring for a centrally mounted ESC.

The length of wire used is the same either way, the only exception…"

"One advantage to a 4 channel ESC would be the centralized weight distribution as opposed to having each ESC out on the rotor arm. When the quad rotates along the pitch and roll axes, any additional weight out towards the motors will result in a…"

"I am mitigating EMI in my quadcopter design by concealing the motor wires inside of the aluminum rotor arm tubes. This may or may not be a great option for everyone; I suppose it depends on whether or not their rotor arms are metal or not.

It looks…"

"Can't wait for the comparison!"

"That's a great representation of the differences of GPS vs. a barometer. I'm researching the BMP085 (same as you're using) and it looks like a great solution. Apparently it offers resolution down to .01 hPa, which is equivalent to a 3.3" column of…"

"Brian,

You've designed an amazing board! I'm curious to know if you have a web page or blog somewhere to discusses this board in further detail? I'm curious to see some of the data logs from these sensors while in-flight. Also, I'd really like to…"

"Care to share the project source code? I'd be interested in studying the graphics portion of this."

"What language was the ground station software written in?"
