Introducing Hertz, a Wacky Robot-inspired acoustic speaker! Named after a unit of frequency, Hertz offers Bluetooth technology and a stylish design, making it a great addition to any gathering or musical performance.

How does it work?

  • Gain competence in soldering electronic components
  • Gain knowledge of Bluetooth technology and audio.
  • Experience the sounds of your favorite beats with the CircuitMess Hertz DIY Bluetooth speaker.

Everybody recognizes technology's significance, though only a fraction of one percent comprehend HOW TO MANUFACTURE innovative technology. We're here to switch that! Using our kits, we aim to motivate individuals to become PRODUCERS instead of simply consumers.

The Science of Sound: How It Travels

When physical objects oscillate, it generates pressure fluctuations that are sent outward in all directions. These waves cause molecules in the atmosphere to collide, thereby creating regions with varying levels of pressure. This series of colliding molecules facilitates the transmission of sound through air. Did you know, however, that sound can also be transmitted through other mediums such as water, metals, and even the human skeletal system?

Sound moves faster in substances of high density than in air; it travels around four times faster in water and 15 times faster in steel. This is why sonar is employed by submarines and ultrasound by doctors to observe beneath the surface. Such propagation of sound is achieved through vibrations, causing molecules to collide in fluids and quickly move the pressure wave through solids.

Fantastic DIY Product for Soldering!

My 15 year old child successfully built the CircuitMess Hertz Bluetooth Speaker He was most certainly proud that his soldering skills were better than he remembered. Both kids enjoyed blaring their music out of it after it was completed. Definitely a huge hit! �
