Do you need it to be recordable/save to some log file or just see what
the weight is ?
For recordable version to build your self you need a HX711 (I have some
spare if needed) on a breakout board and some load cells for 400g (I
only got load cells for 50G or so). Loadcells can possible be pulled
from a digital kitchen scale (I pulled some from a bathroom scale).
Then it's just a question of getting something like an arduino to talk
to the HX711 (tutorials and libraries exist) and then you can start your
If you just want to see it, get a simple kitchen scale, that would be
well within your limits - mine is 1kg and +/- 2g.
