Modification of Tunnel Mount for better FLARM warnings
« on: September 01, 2015, 04:38:32 PM »
Just moved the (8 Ohm, 2 Watt oval) speaker that was in the nexus board to the top of the tunnel mount, just forward of the display.
Audio warnings were "just OK" behind the panel, but this will improve things dramatically.
I use an 1/8" mono extension cable - available at the local electronics retailer - to provide a female connector for the amplifier and male for the speaker in radio / vario / display installations. Cut each end of the cable to length and there's minimal soldering. See link.

We were never very happy with the nexus board speaker, hence the external speaker accessory.  If you have some place to put this thing (it's big...) it works extremely well.  I have mine behind my panel.  Flarm warnings sound like I have a co-pilot with a loud, clear voice.

Had a few flights with the mod now. The speaker works well in that position.
By the way, it's necessary to put a spacer under the Nexus board, as the speaker played a part of holding the circuit board in place.
The Dropbox file got deleted, now replaced.

That's quite clever Jim - congratulations
I wouldn't change back from my solution though  ;)

Just put a new panel together and no longer use the tunnel.
So it's for sale on Glidersource with the speaker included.
