What you need

For this dynamo to work you will need the following:

• Dc motor
• 2x M5x35 screws
• Joule Thief (How to make your own).
• Capacitor
• Led light (the color chosen may affect the effect)

Our suggestions

We suggest printing the gears with a low layer thickness and a relatively high infill to ensure their durability. The housing can be printed with a higher layer thickness, though the aestetics will suffer.

The Transformer head is optional and can be connected to the dynamo by using acetone ([Click here to see how]( http://goo.gl/qr0TVI)).

Check out the instructions to see how to put it together, and please check out our blog describing the design and prototyping of the dynamo.

Autobots, roll out!
