A tonewheel or tone wheel is a simple electromechanical apparatus used for generating electric musical notes in electromechanical organ instruments such as the Hammond organ and in telephony to generate audible signals such as ringing tone. It was developed by Thaddeus Cahill for the telharmonium c. 1896 and patented in 1897. [1] .
Hammond was inspired to create the tonewheel or "phonic wheel" by listening to the moving gears of his electric clocks and the tones produced by them. He gathered pieces from a second-hand piano he had purchased for $15 and combined it with a tonewheel generator in a similar form to the telharmonium, albeit much shorter and more compact.

May 25, 2016 · Tone Wheel. Support HammondWiki. Donate! PayPal. Each tonewheel is a disc of soft iron with a diameter of approximately 2 inches. The rim of the disc is "hobbed" or cut with a specific number of smooth, rounded bumps or "teeth". As the disc rotates, this alternation of the radius leads to a modulation of the magnetic field of the Magnet and ...
Onewheel is a self-balancing electric skateboard with a single tire, used as a means of transportation and as a boardsport. Riders place their feet on either side of the tire to face sideways, leaning forward to accelerate and leaning backward to slow down. The board was engineered to emulate the feeling of snowboarding on powder. [1] .

A clonewheel organ is an electronic musical instrument that emulates (or "clones") the sound of the electromechanical tonewheel-based organs formerly manufactured by Hammond from the 1930s to the 1970s.
