Will try to post things I think are interesting and worth sharing.
These are great! I'll add my own two cents for anyone else:
1) If you can afford it, get a stereo microscope so you have depth perception
2) Another way to make a pad more secure is to put a via through it, since it will be held to the other side of the board

What do you use the UV lamp for in PCB work? Are you making boards yourself?

I will mostly use them and then modify the description to be human readable. Often that includes the manufacturer specific package code (eg. TI - HBH0014A).
PCBLibraries also put out a small update to the IPC standard to eliminate cases where different footprints will have the same name.

just tried with the newest model, and I think we may be at the point of causing real confusion. This doesn't flag for me until closer inspection

And yet it's still cheaper than any of the US fabs

Ah shoot, we've reinvented trains again

I think you may need to get something custom if you want it on a PCB.
If you have access to a laser cutter/milling machine/3D printer you could also make a disk with holes and solder the LEDs to wherever they need to go on the back with some jumpers?

Are you trying to design a custom board? Or find a ring shaped perf board/breadboard?

Do not worry, it will be filled with copper soon enough!

I think the pinecil (or TS101) are good cheap irons ($20-$40). If you have a larger budget I'd maybe suggest getting a used metcal off ebay ($100-$400)

This looks nice! Will have to try making it at some point

We are done, with a final time of 8 hours and 13 minutes. Unfortunately we just checked and it turns out another run with a better route was completed 6 days ago. We'll get em next time 😅
Still though, great experience

Another healthy sprint to cross to the other tracks but we're on the final leg! As a result you'll have to accept this diptych as proof of us at the station.

A healthy sprint and we're on our way to Kenmore for one final transfer
