I tried to update my Eggfinder LCD again with no luck. For some reason the LCD just won't flash with Windows 11. No matter what I do, it powers up and loads as normal. The same USB dongle works with my TRS and Eggfinder Mini, so its probably something to do with my LCD. I gave up and put everything back in the case.
When I tested the TRS at first, everything looked great. It syncs with my LCD and shows continuity with the ematches. The first deployment test wouldn't fire either side. I'm using the same 2 cell batteries that work with my other devices, so I know the batteries work. I double checked all the connections on the optoisolators and soldered a tiny bit more to make sure each pad had a good joint.
Finally, the TRS showed good continuity and fired a match on both channels with the deployment test and vacuum testing. I'd like to test the GPS outside before I fly it, but it did show coordinates for my house on the screen.
