We have 2 versions here; the quicker life-hack style, which is fun and easy to make, and the more time consuming hefty over the top monster. As silly as these devices are, they are actually quite useful for the painter who knows the pain of shaking little pots of paint.

 

There's also a video showing them in action at the end.

Few notes:
- I say things like 'shake' when really it's 'mixing'.
- I say things like 'bolts' when really I mean 'nuts'.

Turns out in the US, Kinder eggs are banned. But maybe you could use some other plastic container like a camera film pot, playdoh, something light weight with a lid maybe.

Here's the video :)


some notes:

- If I was smarter, I'd put step motors to raise and lower the upper section
- Shoulda used a bigger motor, increase the power and added a tactometer.
- Maybe add a bearing in the top section and more LEDs

Hope you enjoyed that and hopefully have a go at making one yourself.
