About Me:

My hobbies inlcude real turbine engines, lasers, cnc machines, 3D printers, and restoring classic cars. I fly RC helicopters, both nitro and electric.


Please tell us a bit about your UAV interest

I'm just getting into the UAV hobby but have lots of experience with RC helis. I have good experience in programming in Arduino as well.

Vernon Barry replied to Frankie Davis's discussion Transmit photos while in air
"Sorry but important things first. While in your head, it may seem logical to power everything from the main battery, Don't do this! Even a good engineer who fully understands all of the electrical problems would see that the risk involved from any f…"

Vernon Barry replied to Tom Petruzzelli's discussion Troubling Take Off in ArduCopter User Group
"In general, when you are close to the ground, no aircraft/heli will stay in a single place because they create a vortex of spinning air that you are trying to balance the machine on top of. It's called ground effect.
This is why flying heli's is a s…"

Vernon Barry replied to Lloyd DeForrest's discussion Help- Compass deviates with increased motor current
"Why would you be at a loss? We know about this, there are about 100 threads on the subject. High DC currents make a magnetic field (exactly how your motors spin). The only way to counteract is to increase distance between the offending wires and the…"

Vernon Barry replied to Rick Eis's discussion Why is the Voltage in Minimum OSD different then the voltage in Mission Planner?
"Betting that if you read the source code for the OSD, a "correction" factor is there manipulating the displayed value.
As to the why, well that's somebodies fix in the OSD code, but it's also designed to work with more than one project (OSD is multi…"

Vernon Barry replied to Rick Eis's discussion Frying new Minimum OSD boards ~
"Let's be clear about this, the failures are usaually from a crap miswiring job or other obvious fault of the user. If you follow the directions with healthy dose of common sense, it goes a long way.
Here's the fundmental problem. The APM and it's IO…"

Vernon Barry replied to Matthew Christenson's discussion Want to double check my figures... Power requirements for QuadRotor kit...
"You really need to read the directions. The APM get's 5 volts from the ESC (Electronic Speed Control) for the motors that inlcudes a BEC( Battery Eliminator Circuit, AKA voltage regulator) to supply the APM with 5 Volts regulated from the battery.

Vernon Barry replied to Julio Martinez's discussion Rookie Mistake in powering up my 2.0 board
"Any idea what I messed up?

Which part of everything important is destroyed don't you understand? When a manufacturer says 5 volts with 10% over as absolute max (AKA 5.5 volts) and you go higher, there is no going back. Some of the ICs such as the 3…"

Vernon Barry replied to Jamie Ahmed's discussion Another ArduIMU project (balancing robot)
"If anyone has any interest in better pictures or code, let me know.
Yes, if you have any code, working or not, please zip it up or post somewhere and share. Don't let your work go to waste and die a dead project with 1 video and no way for anyone el…"

Vernon Barry replied to Dan Clemens's discussion variable pitch quad
"This is a great idea and I already had a simple details worked out.

You can basically use the the stock code for quad.
The first major change required is to change update rate co…"

Vernon Barry commented on Jani Hirvinen's blog post DEVEL: Power distribution development
"I think my comment was misunderstood. I was trying to imply based on the current spec of 70Amps, this should fly nearly any quad. I was attempting to educate other on simple power calculations.
I say that because I read this question as not being lo…"

Vernon Barry commented on Jani Hirvinen's blog post DEVEL: Power distribution development
"is that 70 amps total? or 70 amps per esc.

Hmm, 70 Amps total, times typical 3 cell 11.1 volts 777watts, 746watts per Horse Power =more than 1 HP quad. Otherwise, 70A per ESC means a 4 or more HP quad?????????????
I would hope that would fly the ty…"

Vernon Barry replied to Jesse Shaw's discussion Long GPS Fix Time (Ublox LEA6)
"So what have you changed from last week to this week (hint, hint)?
I have it hooked up to a battery and esc

Likely, it's a power problem with noise coming from your regulator (BEC or ESC). Eliminate the noise and willing to bet it locks just fine.…"

Vernon Barry commented on Jean-Louis Naudin's blog post Autonomous flight mission with the ArduPlaneNG v2.x R5 and AIOP IMU board on Maxi Swift flying wing
"Does Arduplane support failesafe with turnigy 9x radio ?

Not an easy answer. The stock 9x radio receiver doesn't directly support failsafe. In other words, it does a very specific function that cannot easily be modified when radio signal is lost. I…"

Vernon Barry replied to Jennifer Temkin's discussion Battery safety
"Jennifer, I'm not sure how you read that same safety info and didn't get the facts:
I'm wondering if the danger has been exaggerated, or if the cause of failure may be something the poster failed to notice or mention.

Basically, no the danger isn't…"

Vernon Barry commented on Jordi Muñoz's blog post How to hack the PPM signal from any receiver (Futaba) with Arduino
"First I said no, most Spektrum receivers do not have a sum output that is accessible.
Actually, I take that back, the Specktrum remote diversity module can be used, but only with a level shifter and a different firmware. Point being, I don't think i…"

Vernon Barry replied to Matthew's discussion Not getting velocity data from MT3329
"Simple, remember the GPS is a module and has a built in microcontroller. This means it also has a firmware on the module.
Thus, 3DR ships with a firmware that works with the APM. It might be the firmware doesn't use the fields in the same way your t…"
