An automated paint shaker

I am using a nail varnish shaker to shake up my Vallejo dropper bottles. Photos on the blog.

Good idea, more practical than the shaker I built, using the same technic below :



Eficient, but loud and big.

I bought a "hobby" paint shaker years ago that is essentially the same as yours (came with a few extra rubber bands).  Works well in general. For the really thick older paints I have used a battery powered cocktail mixer or an ultrasonic cleaner depending on the bottle.
