ABSTRACT:
A new mixing drill with speed sensing with multiple preset speeds for providing a display of drill motor speed while mixing for indicating the viscosity of drywall joint compound and plaster mixtures and providing a quick and easy method of mixing drywall compound to a specific consistency. The inventive device includes an electric drill, an on off switch, a detachable drill bit with vanes, a drill chuck with a magnetic marker, a magnetic sensor attached to the drill body, a drill speed counter, a motor controller, a keypad, a micro controller and a digital LCD display for displaying drill target speed setting and alternatively displaying the actual speed to target speed ratio for indicating viscosity of a mixture. After the mixing drill with speed sensing is has a target speed setting and the drill is started mixing, the mixing drill with speed sensing operates according to a control program such that pressing a keystroke initiates a control subroutine such that when the motor moves the vaned drill bit in a viscous mixture of materials and the viscosity of the mixture reduces with increased mixing time and motor speed increases with increased mixing time the motor will continue to mix until the sensed motor speed reaches the target speed at which time the motor controller serially connected to the on off switch and the drill motor stops the motor and mixing is finished.
