A bit late with posting the progress, but early on 17/06 I've finished soldering the diodes on both boards. 80-ish of them! and they all seem to work (tested them myself!). Here's a colour variant of the photo too: Next step is to solder all

Left hand side diodes finished now: I'll be starting the right side diodes next :) Then, I'll continue and finish the right side :) I have to say it's a bit frustrating slow soldering at times, checking that everything works, but it's epic fun!

More diodes landed on the left hand side board: Not too many, but I'm new at hot air soldering :)
