About Me:

Interested in Earth science and electronics and using one to help the other. I specialize in embedded systems that primarily make scientific measurement of water quality. I'm hoping to make measurements of water leaving reflectance and invert the results to make inferences about suspended and dissolved aqueous material dynamics. Ardupilot will get me there.

John commented on Chris Anderson's blog post Tutorial: Programming your uBlox GPS module
"Chris,Although I bought from the DIYDrones store, I also noticed that the unit was in its default mode and it wasn't communicating with Ardupilot or ArduIMU. Is it possible it wasn't saved to EEPROM before it was disconnected? Its no big deal for me…"

John commented on Roy Stevens's blog post Ardupilot RF Interference?
"I'd like to say that although my first couple of boards (v1) from sparkfun were missing caps and one had damaged LED's, I have had limited success worth far more than the cost of ten of theses boards, and I am very impressed with the progress of…"

John commented on Chris Anderson's blog post DIY Drones updates
"Great work to all; this is really taking off, especially with the ease integrating airframe files whose diversity will hopefully grow with the project. Anybody have any tuned systems to share. Im making headway with my electristar and will share…"

John commented on Jordi Muñoz's blog post ArduPilot 2.2 Officially Released!
"This release is great, congrats guys. I especially appreciate the integration of airframe specific header/gain files, e.g. easystar. This approach should allow the easy integration of platform specific header files that can be contributed and…"

I want to power my ardupilot and attached xbee 900 pro separately from my Rx, due to the current drain imposed by telemetry and GPS. I have an 1800 mAh lipo 3s on board powering video so I figured to tap into there (although inefficient , I know)…

"Are there any scientific avenues that may be permittable to government research counter parts? I would see this a a possible target and avenue. I would expect there are possible restrictions and guidelines applicable to unmanned surface vehicles yet…"

John commented on Brian's blog post Twin motor setup
"Has anyone used ardupilot in an EDF rig? How do EDF's generally compare in power to weight ratio vs similar prop aircraft? I would guess it could be lower, due to extra eight imparted by the fans and shroud? Should also depend on aircraft design,…"
