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.

We can't stress enough how important it is to read the whole User's Guide thoroughly for this one!

LEAD TIME - IMPORTANT NOTE:
Although this is also described in our Shop Policy page, it is worth stressing that, by virtue of being a small team and not outsourcing a great part of our production, long story short, we sort of make your order on demand.
After you place an order, it takes up to 15 business-days to be ready to ship.
This is why you'll see this module as 'in stock', but this in fact means that we do have all its parts and can produce your module. Thanks for understanding, and for choosing us!
