It is so much smaller than I expected! 🤣

it's not going well. this is way harder than I thought
Just found this video by nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl
Cmon you can do it :)
I may have melted the board. lol
Pic?
not only that but I had to desolder on each pin because it was just globbing up.

How?
I don't know. Definitely suck hard at soldering. this video above makes it look very easy.
It doesn’t have to be pretty it just has to close the circuit. Anything you mess up can be fixed by desoldering it. Just take your time. Go slow. Error on the side of too little solder and add more.
Here is one I just did. Ugly as sin but works

I've been soldering drones for years but still find the raspberry pi header to be a complete pain in the ass. I know my comment is too late, but I highly recommend this going forward.

yeah it was a pain but I finally got the hang of it on the last few pins.
