Default HUDly Classic Power cable.

If I remember correctly the Hudly Classic power supply cable has one of its internal USB wires connected I think to ground in a non standard way from a normal USB power cable and if the unit doesn't see this ground connection it will shut down (for no good reason). So I have mostly just used the original Hudly wiring for our G3x and Dynon installations with no issues. I will dig this up if anyone is interested.

Hello and thank you for your answer,
I therefore understand that if we do not have the original micro USB cable from HUDLY, we will not be able to supply the projector with 12V because it cuts off due to a mass problem.
Also,On a UTube video I saw a projector setting where you can adjust the power off time (Power off Delay), on my projector there is only Brighness and Warning in the menu, is the menu that I Have seen in video is specific to the Hudly Classic for car by OBD2 connection??
If you should have a technical solution for the mass problem on the micro USB cable, I would be delighted !! What I do not understand is that the projector perfectly transmits the image of EFIS GRT for 60 seconds, then cuts.
Thank you again for your answer. Click image for larger version

Default Secret to HUDLY Classic Mini-B USB Power connector

I have finally figured our the secret to the HUDLY Classic Mini B Power connector. Overview is it uses a USB Mini B Male connector and cable powered by 12VDC (Not 5VDC) that must have its unique "ID" Pin #5 connected to Gnd. Details & Parts list in the attached Graphic.

Additionally I have several HUDLY Classic's HUD's that I can make available to interested Python programmers that have Garmin G3x, Dynon D10/100 & Skyview or MGL EFIS systems and want to help with our HUD - Raspberry Pi open-source programming project. Software is fully usable now (based on F18 HUD), we just need to continue to enhance it. Check out our GitHub site and Send me a PM.

Default New style Hudly

Does this cross over to the new style Hudly? I have one, and have yet to use it as I wanted to - HUD in my -6. If this data works the same, I may be able to do it, finally.

Have you tried putting it on your glareshield? It takes up rather a lot of space, and overhangs the edge. Unless you're referring to the Hudly Lite, which only offers Speed and RPM... Not sure if you could connect that to anything but an ODBII cable.

Default Dual XHUD 1000

What do we think of this HUD?
https://www.dualgpssolutions.com/exp...ead-up-display

Has anyone used it with any success? Looks like it is not fully infinity focused.

Neither is the Hudly.

This would work a lot better on a Cessna 150/172 that has a deep shelf on top of the instruments in front of the pilot.

Hello Hpmicrowave (Cecil)
Thanks a lot for your information, in the same time we received information from GRTAvionics that confirm your advice about power connector (USB Mini).
My friend engineer found a solution, by soldering the Mini USB connector pin 5 (ID) to the ground inside theClassic HUDLY projector.

This solution need to open the projector but it avoid to use special connector.
We have tested this solution, it's work perfect !
Thank you so much for your precious information .
Best regards from France.

Default USB power for Hudly Classic or other HUD displays

Your welcome. And if you want to use the serial data output from a G3x, Dynon, or MGL EFIS to drive a HUD display send me a PM. Can fix you up using a Raspberry PI as the interface processor.
