Ugears wooden 3D brain teaser Dynamometer – perfect gift for all ages

If you have trouble deciding what to do with your day then the Dynamometer is just the machine for you. Similar to our Pneumatic Engine, this model operates by turning air pressure into motion. The difference is that this model will give direction to your otherwise aimless day. Blow on the top gear to set the mechanism in motion. The air pressure you apply spins the arrow until it lands on your task for the day. Now get to it!

The Dynamometer is one of the simplest UGEARS models but at the same time it demonstrates several basic principles of mechanics, including the cascade of gears and the mechanical junction known as the Geneva drive. Self-assembly; No glue required

Ready to Build

Ugears models are made from sustainably sourced, laser cut plywood sheets. Everything you need is inside the box, so you can get building right away.


No batteries, no electricity, just Ugears. All mechanical models are powered by the ingenious mechanisms built by you. Just wind up your model and watch it come to life.

No Glue

Pieces have been designed so they will either click or slide into place. No glue or any other kind of adhesive is needed to build your model.


Models take inspiration from real life inventors and engineers, such as Da Vinci and Galileo. Learn the history behind the model as you build.
