BTW, I used the free iPhone app "Wiring Harnesser" to document the wire runs. Nice thing is you can add photos to document pin-outs etc. I found it really easy to use, made exactly for the purpose, e.g. you can add the color codes of the wires. You always have your wire runs and pinouts at hand.
Then, it has an export function that creates an SQL dump, so I converted it to cvs and imported it into a google sheet. That allows for easy sorting if you want to see for example all your serial lines.
Interesting! Can it import? Would be much easier to type it all up on the computer.
@@BuildFlyGo The import and export is meant to be its own proprietary backup / transfer to another device format. It's a zip file that contains the photos and the sql database (sqlite). The database has 7 tables that are intertwined. To convert the database to csv, I had to write a 54 line SQL statement that puts the data together as a flat dump of connections. Now, if you would want to import into the database, you would have to fully understand the schema and keep everything consistent. Doable, but potentially a lot more work than just typing the stuff in. While entering you are only picking connectors from lists, so the actual letters to enter are the pin numbers, pin function and your signal name.
Hello from Minnesota! I was wondering when we would see the next episode. Looking at all those wires makes my head hurt!
We are back to a weekly cadence! :)
Our family is hoping to build an RV-10 sometime in the next few years. This is the part that seems most intimidating.
It's totally doable, just takes time and patience. The docs available are excellent, and the community is here to help. There are also some excellent avionics shops out there that will do it for you for very fair prices.
@@BuildFlyGo maybe in the next few years things will become more plug and Play.... Although I somehow doubt it. Thanks for the response, I really look forward to following your progress.
I missed not seeing updates and I commented about that on your "Fisk arrival" video. You're correct in stating that this is the boring part. It just adds to the credibility of the old adage, ""90 percent done and 90 percent to go"! Other than the obvious cost difference, I'm curious to know why you didn't farm this out to one of the outfits that makes wiring harnesses for a living. You could likely be ready to fly by now.
A few reasons but mostly because I wanted to do it myself. It’s actually pretty fun and you get to -really- know your avionics. Also I wanted to make some videos to show that this can be done by a regular airplane builder and show how I went about doing it.
Nice, I wish I had seen your way of doing it before I did mine a year ago! So much neater.
Just additional info on the serial port selection, I am sure you know that: You said - any serial port of the GDU display, you can figure it out later - there are exceptions: if you have more than one GPS, there are certain rules for which one has to go where to become either GPS1 or GPS2. Then, for the VPX serial line, there are rules concerning it going to the PFD or MFD.
I was beginning to wonder about your status. I actually reached out through "channels" to make sure you were ok..
Thanks for checking!
Really interesting video. I hadn't thought about the binder approach. I was thinking harness design software, but acquisition cost is high. Will you be talking about the labeling system you're using at some point and what labels and label printer? Finally, I think I heard you mention you're a Garmin ambassador. Wondering why there's point-to-point serial communications instead of something like a can bus to network everything together?
There’s both :) G3X uses a can bus but there are some redundant serial runs and serial connections to non-G3X devices. I’ll have a much more detailed video coming soon!
Looks like that engine mount serves double duty! 👍
Great video! I would love to see an example of your approach to selecting the wire length for specific run as well as the process you went through when laying everything out on the table to start running wires. Keep up the good work.
The review video will be more detailed and will cover this ;)
@@BuildFlyGo Thank you. I am also interested in that. Feel free to go into great detail. We will not be bored.
don't shorten wires too much -- maintain service loop! (voice of experience)
For sure! We included service loops in the measurements, then added a few inches for any mismeasures. Expecting most of them will get an inch or two snipped.
@@BuildFlyGo excellent vans forum discussion on service loops with lots of pics. You probably need more than few extra inches for some components. The benchmark is for example for the pfd enough of a loop you can take it out and set it on your lap (loop also you to pull out to get at connectors on back. Some loops likely need to be a 12 inches or more.
Can you say which labeling machine you are using? Any specific brand labels? Also, do you have specific thoughts on an alternator filter based on RV-9A experience?
I use a Dymo LabelManager 160 with generic D1 label tubes. It works great and I think it was only $20? I've had it for years :)
I have not added an alternator filter but I hear it might help my audio recordings :) I can't hear an alternator whine during regular (non-recorded) flights.
@@BuildFlyGo interesting. Concur, your videos sounds good. I wonder if newer alternators have some type of capability built in. Thanks for the Dymo recommendation.
