Edit: using a 25W iron whose tip wasn’t heating up properly. Had to use its sides to get the solder to melt, which affected precision.
It’s ugly af but it works
I’m a solder soldier
And I’m so sorry for that last part
Now I need to by something that holds everything in place, because what took most time was, well, that.
Maritime electronics, mostly. Autopilots, radars, echosounders, etc. Plus interfacing radios with positioning systems.
