Also known as a button-on-a-string, the buzz-saw whirligig is a noise-making device which utilizes an object centered on a loop of cord. The buzzer described in Home-made Toys for Girls and Boys spins a cardboard saw blade to generate its hypnotizing whirring sound. Using both hands the enjoyer must hold each end of the loop and rotate the saw blade to wind the loop. The blade is whirred by adding and releasing tension on the loop which unwinds and, because of the angular momentum of the blade, winds the loop again in the opposite direction.
Making a buzzer is a fun, fast and instantly rewarding project. Cut cardboard, glue a “spool-end” on the center of each side, drill two holes for the cord in the spool-ends, thread the cord through the holes and tie the ends together to create a loop. To my amazement my first buzzer worked splendidly; however Fleur our poodle isn’t as amused by the osculating pitch emanating from the new mysterious gizmo.
I decided build a bunch of buzzers as swag for the Newark Maker Faire. Friends saved cardboard from recycling and donated it to the cause. The cord for the buzzers was retrieved from a pile of bakery string saved from years of bakery boxes. Small bits of recycled broom handle are substituted for spool-ends because I don’t have many spools in inventory. The title artwork of my exhibit was printed on the cardboard using a carved linoleum block. To print each buzzer ink was applied to the carved linoleum block using a brayer, the buzzer cardboard was placed over the inked block and pressure was applied to transfer the ink from the block to the cardboard. When the ink dried I cut each buzzer out with a pair of scissors.
Please stop by my exhibit at the Newark Maker Faire, Saturday April 30 to pick up your free buzzer while supplies last!
