No batteries required


Materials: LJUSA dynamo torch

Description: It was time to replace the batteries from our daughters toy piano. But instead I removed them all and mounted inside the piano some components (gearbox and electronics) from the IKEA LJUSA dynamo torch.

I just needed to drill some holes and solder two wires, that's all.
Now the piano will never be short of energy.

  1. Brilliant!!!
    I want that in all my childrens toys!!!
    And it looks almost perfect. Maybe you can find some flat heat screws... but it's already a wonderful, eco-friendly idea!!!

  2. And what if we change the capacitor, that seem not to be good enough at storing energy, in order to improve the performance. I'm just wondering, because I do not have any knoledge on the electricity field...

  3. nooooo- don't you know noisy kids toys are supposed to have batteries... so parents can use the "no you can't use it honey- we don't have any charged up batteries" excuse and save their sanity???!!!

  4. AWESOME! Wish I had these skills!

    Usually, I think I am clever for ordering a set (2x what is called-for) of eneloop batteries when I buy a new battery-op device. I shall have to revise my opinion! :D
