Two things this week:
I am considering a farnell order this week on Tuesday, for Wednesday
delivery.
If anyone wants stuff, please let me know before 17:30 on Tuesday
There interest in getting some TQFP ATMega 328P devices. If we can put
together orders for another 10 or so we can get them at £1.46/each.

I suspect Ben uses solder paste and a hot air gun and an eye loupe!
However it can be done by wave soldering and patience. You need a PCB with
pre-tinned pads and a solder resist to prevent bridges (professionally made
PCB).
It can be done with a steady hand and patience…and less caffeine than
usual.

Also don’t underestimate the value of a flux pen, it really helps as
the solder flows nice and quick, and only where you put it
