I need a design of a device that is able to generate random frequency in a setted range (for example 50Hz - 200KHz). This device should be connected to a piezo or a vibromotor. An amplifier needs to increase or decrease the intensity of the vibration. With an User Interface is possible to setup the parameters (frequency + intensity).
Please note: I need only schematic and PCB design.
