Strawbot

Gather your items together. Cut 2 of your straws in half.

Add the three full size straws to the ends of a 3-point Strawbies connector.

Add two 1-point Strawbies to each of the three legs.

Connect each of the 3 legs together by connecting the single point Strawbies with one of the half straws you cut earlier. (You will be left with a half straw that you won’t need.)

Attach a marker to your last straw with a rubber band, then place the straw through the center hole of the Strawbies structure.

Add a rubber band above the Strawbies structure to the straw holding the marker. This can be used to adjust the height of the marker so it comes in contact with the paper below.

Tape the leads of your pager motor to each side of a CR2032 battery. Since the motor will vibrate no matter how the power is connected, we don’t need to worry about the polarity of the battery.

Remove the sticky from the back of the pager motor and attach the motor to one of the single connector Strawbies.

Now you can place a piece of paper under the bot and remove the cap from the marker to see it jitter and draw.
