Start with the Arduino mouse/keyboard libraries. They're quite small.
In continuity I have seen less, but also it randomly doesn't work as you can see in the video. (photos of inside at the final part)Let's start with a clear focused still picture of the pcb (both sides). The photos in youtube are not good enough for me to see.
It isn't an economic issue, DMM is more or less cheap so it could be thrown away, but sometimes we do challenges for ourselves: could I repair it?Yes, I repair low cost items generally for fun, challenge and learning purposes.
Anyone know where I can start?In some of these low cost meters, I suggest checking the range switch for dirt/debris/contamination. Bad or cold solder joints can also be problematic in low cost meters. Clear focused well lit pictures will help us help you. If I can't reading the silkscreen writing on the pcb, then the pictures are not good enough.
I know it's not a "real" backup, but for just copying over my work files I use mirroring with "robocopy" on a regular basis, or I will use FreeFileSync (http://www.freefilesync.org/) to just mirror over all my important files to an external HDD.
I don't need to apply additional flux. What's in the solder is plenty.This is true for a one-off. For doing 2 per board x 100's or 1000's of boards, the flux is for speed. Holding solderwire in one hand, iron in the other, and tweezer with your toes... not good.
