Maker TPalowski13 built an experimental Bluetooth speaker that squeaks a rubber chicken in time with the bass in music. Audio from salvaged Bluetooth earbuds is analyzed into frequency bands, and low-frequency signals trigger a solenoid to squeeze the toy. A custom 3D-printed holder supports the chicken and actuator. The chicken is not reproducing bass notes; it squeaks along with the beat.
Instead of reproducing the bass, it makes a rubber chicken squeak along with it. The rhythm section has acquired poultry.
Sole-Sageel automates the gesture of lowering your beer mug below the other person's during a toast. Two long-stroke solenoids physically raise and lower the mug.
The device was created by Pokosute for Takaha Kiko's 13th Solenoid Contest, where it won an award for especially absurd and useless creations. On the linked page, see the section titled 自動忖度マシーン「ソレサゲール」.
A tiny gesture that normally takes one hand now gets two long-stroke solenoids. Automating humility somehow makes the whole ritual much more elaborate.
XA10C4's Ruler Drive turns the familiar trick of twanging a ruler over the edge of a desk into a four-voice automated instrument. Stepper motors change each ruler's effective length to set its pitch, while solenoids strike the rulers; the machine is controlled over MIDI and the published demo performs the notoriously fast piece Rush E.
Built from an aluminum frame and 3D-printed parts, it mechanizes a very simple school-desk noisemaker into a programmable musical robot.
They've automated the classroom trick of twanging rulers—and multiplied it by four. Bring this to school and you might get scolded by four teachers at the same time.
