Good to hear you figured it out. You may want to use a Arduino LM35 temp sensor. They output a linear Temp to V ( 10mV/degree C) making you calibration much easier. You can find these for about $10 and already on a board with leads. Works with 4 to 20VDC excitation.

I haven't check your calibration data but just looking at the fact you are capped at 36 ( 37 C = 100F) is it possible you have your cal in Degrees F, but your user preference is in Degrees C? check you user config file. units_temp_oat=UNITS_TEMP_F units_temp_other=UNITS_TEMP_F

CGameProgrammer, What kinda plane is this - Metal or Composite? If it is metal you should make sure your Mic and Headset jacks are isolated from airframe ground. They make nylon washers that keep the Mic and headset ground from contacting the airframe ground. If you do not have these you can...

Connect your circuit as I have attached, with the diode and contact input connected to the "I" terminal.  Configure the contact levels as 0 to 3.0 V = Starter not engaged.  3.1 V to 5.0 = Starter Engaged. The diode should be a 1N4004, 1N4005, or 1N4006.  Any will do, whichever you can get...

Just another thought regarding this. If you are trying to determine if the starter relay sticks you need to connect your contact input on the big wire between the relay and the starter (load side or contactor). If you are connecting this to the control / coil wires it will only show if the key...

Try setting your Ranges to: Range 1: enable yes, name ENGD, color white, top 5.0 volts, bottom to 3.0 Volts. Range 2: enable yes, name nothing, color black, top 3.0 volts, bottom 0.0 volt The "Pull Up" in skyview is keeping in the high state. You may need to add a diode in series with the...

I have a Glasair with retractable landing gear. On occasion, the landing gear pump must kick on momentary to keep the landing gear up in the wing. If the battery is old and weak when this happens I get a power drop and it will kick off the servos. So, make sure something like that is not...

From the vendor data sheet provided in original post we have: Pressure Range of  0 to 1019.78 mm H2O, convert this to Inches. mm to Inches is 1 Millimeter = 0.03937007874 Inches. So, the new pressure range is 0 to 40.14881889 in H2O. The sensor has a full scale output of .20V to 4.7V...

I am using the TED antenna for my ADS 472. I notice lower performance with the ADS 472 vs. ADS 470. I see traffic blank in and out often. Also, see screenshot of the full USA weather with a lot of holes in coverage. Looks like the receiver is loosing lock and dropping data. This was an 1...

Dynon, I also recently upgraded my ADS from the 470 to the 472 and notice traffic blinking on/off the display. I never noticed this with the ADS470 so I feel it is related to the above posts. I am planning on flying to Oshkosh later this month and will get a lot of flight time to experience...

This is from the "What's New" in Skyview system software. Version 15.0.2 11/3/2016 New: Pitot/Static test mode that elmiminates the need for display restarts during transponder checks. Available via SETUP MENU > HARDWARE CALIBRATION > ADAHRS CALIBRATION > PITOT / STATIC TEST MODE. I had my...

I would add you can determine if you have a static port position error by taping shut one of you static ports and taking a leaf blower and blow across the open static port. Emulate in-flight airflow. While monitoring this on you SV if you see an altitude change you have static port position...

I do not have the EARTH X battery but found reference in their manual for the output you are having trouble with. You should connect it up as I have it on the attached drawing.  It should work.  if you connect it to both the panel indicator and the EMS you need the isolation diodes.  The EMS...

Don, Per the 15.0 SV install manual: You must set the RS232 output on your GTN to "ADS-B+" in order to be compliant. If you do not have that option in your GTN then you need a firmware update for the GTN. See page 11-38, SV 15.0 Install.

Looks like your GPS was not yet receiving a signal. The GPS needs to be outputting data in order to get "YES" with the compliance message. You will need to push your plane outside the hanger.

The ANSI standard color code for a type K thermocouple is RED and YELLOW, whereas YELLOW is +, and RED is -. Your guess is as good as any. You can connect it to a milivolt meter and place the probe between your fingers and verify the voltage rises as it heats up. The lead that is connected to...

Homebuilt101, Dynon can confirm this, but I believe if you are tapping off of LED's the "open or off" state may be too high impedance and not "pull down" the contact input enough to get a low "Gear Up" indication.  If this is the case you will need to add a pull down resistor ~5K Ohm should...

The un-energized lamp serves as the pull down. One side of lamp is connected to ground. If I remove the lamp or it burns open it will "pull up" and show as a "Green-Down" indication.

I also have a Glasair with capacitance plates in the Header tank and got a very small voltage change with each add. It works fine and accurate. I would just complete the calibration and see how well it works.
