Solenoids in the seeedstudio depot?

Hey guys,

I noticed that this shop is missing some solenoids!!

What are they good for?

mm, let’s see! Here is one old example where someone is using a bunch of them to create music!! :smiley:

And here is one where they are used for a different type of graffiti

And here is a solenoid controlled by arduino:

I am waiting! I hope I find them in the shop soon! :stuck_out_tongue:

All the best,
