At ADDAC we always admired the geniality of Neil Young’s Whizzer, way ahead of it’s time, a great example how great ingenuity and engineering can come together to make something great. Inspired by it’s motor controlled method we created a 4HP solution to control any knob that doesn’t have a CV input, while also possible to use for other gear as well (within certain distance constraints).
We use a Servo motor which is a specific type of motor that can be digitally controlled to go to a precise angle. This motor is controlled by a microcontroller that also receives an incoming CV voltage from 0 to +5v and lineary converts this voltage range to the 270 degree Servo motor range.
Using a spring wire and metal couplers the motor shaft is then attached to the target knob to be controlled which will turn as the Servo turns.
Two other knobs [MAXIMUM ANGLE] & [MINIMUM ANGLE] further allow to control the “sweet spot” of the target knob, setting a smaller Servo range.
Raising the [MIN ANGLE] knob above the [MAX ANGLE] knob inverts the Servo range.
