When you do consider logging, would you please make it direct to USB MSC.
Thanks,

We always assumed people would rather not be required to have a USB stick plugged in to datalog, so we were going to store it internally and then let you save it to USB when you wanted to. Is there a reason you want it direct to USB instead of to the internal storage?

Internal is great.... Raw data should not be terribly storage intensive so I suspect you'll have at least a ten or so hour FIFO file set up (?).
I currently am logging data to a small card http://www.sparkfun.com/products/9530 with a 4gb microSD card. It should roughly log about 1000 hours of flight time before it fills up. I keep forgetting to take a photo of my setup but will post it eventually.

This little device looks very intinteresting. I would love to see your setup. Are you loging EMS data, ADAHRS, NMEA or what? How are you powering the device? I would think 3 AA batteries would last forever at 2 to 6 mA.
I was most interested in logging engine data, but it will log everything off the serial port, which can be adahrs, engine and system. I am thankful that Dynon stuck with simple ascii output. Power comes from the +5V pin on the EMS for auxilliary power I connect with a single barrel molex. Then using a DB-9, i connect TX, RX, and GND. Oh you do need another small board for a few bucks to convert from RS-232 signals to TTL level for the board at http://www.sparkfun.com/products/449 as well. However, it's a pin for pin hookup as well.
I WILL remember to take that photo.

Pardon me for asking, but what do you need all this logging for? i.e. for what purpose?

Maybe it’s just me, but I like to know what’s going on with my engine. I also believe in predictive maintenance and learning of a potential problem before it becomes a real problem.
I used to have a Blue Mountain EFIS-One and I downloaded the log file after every single flight. I would always load it into Excel and make a quick graph of pressures, temperatures, volts and amps. I found unusual things going on more than once. It only took a few minutes to do this.
I also used data graphs to troubleshoot and tune engine cooling problems. It was important to know OAT, climb rate, power settings, fuel flow and density altitude to do this. The flight data has to be logged at the same time as the engine data so you can correlate the different readings. Seeing a change in CHT is not very useful unless you know that you initiated a climb or just leaned you engine. It’s the only way to really know what’s going on.
I would also use the GPS and altitude data to record memorable trips and analyze my pattern work. I loaded the data into Google Earth to see my flight path. These are just a few of the many advantages you can get out of logged data.
Here’s a picture of a flight to Chicago I took a few years ago.
This system will not allow me to upload a picture for some reason, so here are a few links to some screen shots I made…http://www.flickr.com/photos/50445804@N05/6535317889/in/set-72157628478132683

Thanks Darrel.
Re: RS232 Logging
Hi all,
I'm trying to pull data from SV-touch panel (serial4) to laptop, Using the Dynon ADAHRS serial output data setup. Had to set baudrate to 57600 on both SV-touch and PC in order to get something out, but the data is un-readable (strange symbols lot's of Y's with two dots over them). I'm using a free version of "RS232 Data Logger" (Eltima Software) installed on Laptop. Since I'm only reading data, I should only need the RX-Out (SV-touch) ,pin2 on a 9-pin serial connector, and pin5 ground, right? It says to have a common ground, on both the SV-touch and the PC, how can that be done? I connected the ground from the aircraft to pin5 only, not sure if this is correct.
I want to stream this data to a Radio transceiver made by Laird (CL4490), which then uses a wireless connection to a reciver, where this data can be monitored.
best regards,
Tlynyrd

Re: USB Logging- flightplans
What I keep wanting is to move .gpx flight plans TO the skyview for easy future access. I have one procedure I use everytime I land (RNAV) yet have had to go look for the USB to get it plugged in to load. Although I should have to plan for this and assure its there before takeoff (which it wasnt since I needed the stick for the 11 upgrade and forgot the .gpx was moved) it would be so beneficial to have easy access to a flightplan without a need for a USB stick.

I signed up to a free account with Savvy Analysis. After each and every flight to date I upload my data log file to my account and have been immediately able to see all the engine and flight data in graphical form. I can display multiple parameters on the screen and see just what is going on in detail. This was particularly useful after first flight when I was naturally apprehensive that all was well with the engine. Also, recently when I was having severe spikes induced into many sensors on SL40 transmissions and again when the upgraded EMS was returned and I was getting crazy ammeter readings. Savvy Analysis also have a paid subscription where their experts will monitor and advise on your engine health. I have to shake myself occasionally to see if I am dreaming - the computer age came at the right time for me and my GlaStar build, Savvy Analysis is like cream on my cake!
Tlynyrd - If you're not seeing the text as shown in the manual, then there's either a baud rate mismatch or one of the other parameters of your serial port RX not quite set right. Also, if you're using a USB-Serial converter on the PC to create a serial port, sometimes driver issues can cause you to not get good data through.
Hi Dynon Official,
Sorry for the late reply, you were right, i had to change the baud rate in the control panel on my laptop to 57600, which is the same as the Dynon Skyview touch panel configuration. It works fine now, but is there a program that would convert the data into something readable? I'm streaming this data to the laptop over a wireless link that would show me the actual data transmitted, and it would be nice to have the same kind of screen on the laptop that the Dynon shows.
thanks for your help
