Update, the P-TACH has been released and is now available from MakerPlane as a finished product, kit or open-source design. http://makerplane.org/?p=1679 This thing really works, it eliminates the headaches of fine tuning the p- lead resistor and fixes the applications where there is no sweet...

Why not just allow a more comprehensive set of screen layouts? If Dynon opens up the code for screen layouts, here's what I suggest: A selection of EMS widths: 5, 10, 15 , 20... A selection of EMS heights: 5 , 10 would work for horizontal strips. The ability to split the EMS into multiple...

Me too.

i would like the capability of increasing font size independently of widget size on the EMS layouts. It would be nice to have this for the map page as well. Presbyopia is winning the battle! Is there a hack to do this, or can it be put on the list for future revs?  The SkyView system is jam...

I've been flight testing my design for a device that stabilizes the p-lead tach pulses from magnetos.  As often reported on this forum, it can be difficult to find a stable sweet spot by choosing the right resistor value in series with the SkyView's RPM inputs. I published a preliminary...

For those who don't want or can't fit the AP Trim controller, I developed a 2-channel variable speed (speed scheduled) that sniffs the serial stream of a SkyView or D10x.  It also supports trim switch fault detection and correction.  FMI...

Yeah! SV 10 has eliminated all of the funky startup issues with multicolored bars and flashing screens. It also boots much faster, well done. I did have a crash during setup, but i can't reproduce it. I like the new ems gizmo that displays the label and units on the same line as the value...

Here's the results of my comparo of Jepp vs Pocket FMS: I've always been disappointed in the Jepp Canadian data. For example, clicking on airspace information in the Jepp database provides wrong frequency information. When flying in the Vancouver VTA area, which is very complex, the...

ADS-B, in my opinion is primarily for the benefit of ground stations.  Because the FAA introduced the UAT as an option in the US for ADS-B out and ADS-B in, there is a significant risk that some aircraft will be blind to other traffic in non-radar areas or other countries (Canada for example)...

Touching is good!  It's nice to see Dynon embrace touch screens while still maintaining and even enhancing a knob based interface.  Personally, I like dedicated buttons... In stressful situations they are easier to use. The only disappointment in the long list of features is that Canada is...

I'm flying behind a stick shaker of my own design that sniffs data from a d10a or a SV serial stream. Impossible to ignore and better than the visual display i designed a few years ago for AOA. It uses a custom driver board and a special stick mounted actuator. 'Fairly easy to make' is only...

Ask your avionics shop to perform the tests according to the CARS and provide you the results. You then sign the logbook using this information. That is the correct and legal procedure. They are not signing your logbook, only providing you and interpreting the test results. Vern

Caution. If you use the external control for the SV, it may not work properly when the SV is running on the battery backup. This is because if you have an electrical failure, the dimmer voltage will drop to near zero, and the SV screen will become very dim. It's not fun to have the screen go...

So it actually makes sense to use USG instead of liters, because I can get 0.1 gallon resolution. Using liters, I can only get 1L (0.26 gallon) resolution. I can't use the 10X scaling factor because it wouldn't jive with the float sender values. I can switch to USG now that I have calibrated...

How do I adjust the precision of the fuel flow readout? I'm set to liters/hr. It might be obvious, but I've missed it. I'm looking for readout in tenths of a liter/hr for injector balancing. Vern

Just to be fair, my Garmin GPS has had outages like this as well (not at the same time). The cause may be external. Why not allow a status field to be added to the MAP page?

Twice, in flight, I have received a primary GPS Failure messages. Since I have a secondary GPS source, this apparently was of no consequence, other than the message. However, I can't see anywhere on the SV screen that shows GPS 1 or GPS 2 status in a convenient location. This would be useful...

Here's some in-flight information on the expected magneto waveforms. The first trace (magneto-1) shows a 2400 rpm primary trace on the top, showing both positive and negative firing events.  The pulses have a large damped sinusoidal component that needs filtering.  The bottom trace is the...

Re: IO-540 P-lead resistorS---SUCCESS! Update: Did some circuit optimization and testing with a 5V power supply. Amended design attached.

I use this feature all of the time... actually NM/L. It really helps to understand the fun/fuel tradeoff.
