This is a very comprehensive list (and the organisation is pretty inspiring) but missing a few things I have personally found very valuable in what I do (which involves a mixture of smallish new projects and retrocomputing repairs/upgrades/etc) - main one I'd mention is low melting point solder to use for desoldering larger components (both plated through hole and SMD) - it took me ages before I tried it and it's made a huge difference at least for me. Chip Quick is the well known brand but you can get cheap unbranded "bars" of it as well. I've also found desolder stations much easier to get on with than solder suckers - Hakko 808 is what I see recommended a lot though it's not what I have. Ultimately if it's temperature controlled I think there's not much to choose between them.
Finally there are some great very cheap logic analyzers out there - modern oscilloscopes will do this too but you have to get pretty high up the price list before you can make do with just one device for both uses.
Regarding desoldering tools, I also hate solder suckers and instead use a mix of desoldering stations and desoldering braid. I used to very heavily use desoldering tools in challenging situations, such as large traces/joints covered with a lot of flux residue or conformal coating. I ended up working my way up the Hakko desoldering line and developed some opinions.
The Hakko 808 is discontinued and the FR-301 seems to be the current replacement. I used a FR-301 for a while and it was a fine tool. I've now switched over to a FM-2024 which connects to a FM-206 base station (among others). I found out that with heavy use I had many more issues with the FR-301 due to the longer tube between the nozzle tip and the solder capture chamber. The FM-2024 has a much shorter tube and the nozzle is integral with the tube. These factors make the FM-2024 more reliable and easy to clean under heavy use. The FM-2024 is also more lightweight and can be used with a gun or pencil grip. So if you do a lot of desoldering, desolder a lot of gunky/fluxy stuff, or have/want a compatible Hakko soldering station, I would suggest the FM-2024 over the FR-301.
Interesting - though for nearly £1900+VAT for the FM-206 (including hot-air and soldering tools as well as desoldering to be fair but excluding tips and nozzles) I'd hope it performs a lot better indeed!
The idea is that you add it into the solder already in place. That in turn lowers the melting point of the mixture.
With a low melting point it takes a lot longer to re-solidify after you heat it up which means (if you do it right) you have a lot more time to work - so you can get the solder mixture for all the connections on the entire component liquid at the same time and just pull the component out in one go without damaging the board or the component.
You do then need to clean it up as its a bit messy but solder wick works fine for that.
Finally there are some great very cheap logic analyzers out there - modern oscilloscopes will do this too but you have to get pretty high up the price list before you can make do with just one device for both uses.
