Build Instructions

You can follow the instructions in the .pdf linked below to create the winder's brick assembly.

Motor Prep and Wiring

Fit the motor axle adapter onto the motor shaft -- either side is fine.

Then, screw the motor wires into the two Crickit motor terminals marked "1" as shown. The order doesn't matter.

Gearbox

The TT motor spins a bit fast, so we'll gear it down to decrease speed and increase torque.

Once assembled as shown you can adhere the motor to a 2x4 tile using double-stick foam tape.

Watch Holder

Using the .pdf instructions as your guide, build the watch holder. This will allow you to strap most any size watch to the wheel and insert it in the open frame so that it will rotate in the proper orientation.

Tiles

Continuing on with the .pdf instructions, add tiles to the exposed studs for a nice clean finish. You'll leave a plus shaped section exposed to mount the Crickit and Circuit Playground Express.

Crickit Mount Plate

Follow the instructions in this guide to 3D print the Crickit mounting plate that adapts it to LEGO-compatible tubes.

Then, add four 2x4 bricks as shown. These simply press together to connect, relying on clutch power to stay in place like any regular brick.

Crickit Connection

Use four M3 x 6mm standoffs and eight M3 x 4mm screws to fasten the Crickit to the mounting plate.

Add Watch

To add the watch simply strap it around the wheel and then squish-fit it into the holder frame as shown here.
