Avionics Status Update

I don't have much to say here other than we can see the light at the end of the tunnel! I debated early on having the wiring harness made, but I am very glad to have done this one myself. There is a level of understanding of how the bytes are flowing over the lines that one would not get if someone else were to have wired and configured the system. 

Everything in green is now complete with only a couple of additional wires to terminate (colored in orange).

Wiring

I have been a bit busy lately not posting, but I have been building! For the past couple of weeks I have been really straightening out my electrical system. I spend a lot of time in CAD software at work and for me, it made a lot of sense to build out my electrical system in an actual schematic editor. While Eagle is more geared around building PCBs, it's schematic editor is pretty straight forward. It is also free to use, so I figured it would be a good platform to build out a GARMIN parts library so other people can benefit for the hours spent building out the parts. If you are looking for Eagle it is now part of Autodesk. You can get it here:

Over the next couple of weeks I plan to get the rest of my wiring system into Eagle. I have most of it in a drawing right now, but I am working on cleaning it up. I am at the point where I just made the connections, as I build the wiring harnesses themselves, I have been putting in the wire colors into the schematic and marking them off as done.

Wiring Diagram

My wiring diagram is coming along and I am feeling pretty stable on the overall plan now. I am going to go with a 2 battery approach so I can have a master and aux. The ignitions connected to the master_battery_bus and aux_battery_bus. The aux bus will feed the backup power on my avionics while the master bus will feed the main_bus. The aux bus will get it's power through a diode connected to the master bus. I cannot recall what exact AeroElectric diagram this is, but I think it is a hybrid between Z14 and Z19 if I recall correctly.




I have made decent progress on building the "Garmin" and "VPX" eagle library. I still have a bunch of components to add, but I am doing them one at a time as I add the component to my electrical diagram.

Send me an email if you want me to send you the LBR with the Garmin and VPX components.
