does anyone know a technological solution to "hands are too shakey for SMD soldering"? I am thinking of some sort of device you can place your hand on that dampens the tremors
(please RT, would really love for my gf to be able to solder fine pitch SMD stuff)

so far a manual pick & place machine (~hundreds) and Ustar UA90914 (https://www.aliexpress.com/item/1005004749678342.html; ~$25) are the top suggestions; the Ustar device looks really promising!

microscopes/binoculars seem to work so well they even help people with Parkinsons, which I didn't expect so I'll now bump them higher in priority

@whitequark I think you can go a long way by providing a really solid place to rest your hand, fully take all the weight off it, so that only your fingers are doing the actuating. When I get small shakes from over-caffeination, if i'm not at the PnP i'll just stack up a few boxes next to the vice.

I remember from various youtubes that hand / tool support is a vital part of production welding too. Carefully re-arranging the work-piece and the welder feed-lines to offload the static lod

@whitequark Over time I found myself subconsciously extending a pinky to touch down on the vice to try and do a similar thing (took years to train myself NOT to drop my pinky right into freshly applied solderpaste...)

The pinky technique always helped a small amount, but the real deal is to fully take all that weight off.
