Abstract: Tool enhancements, and related systems and techniques, are disclosed herein. For example, a nail gun may include a trigger; an actuator to drive a nail in response to a pull of the trigger; a sensor to generate data indicative of a property of operation of the nail gun prior to or during driving of a nail, wherein the property is a resistance experienced by the nail as it is driven or an angle at which the nail is driven; monitoring circuitry to determine whether the data generated by the sensor satisfies a predetermined event condition; and an output interface to provide an indicator that the predetermined event condition has been satisfied in response to a determination by the monitoring circuitry that the predetermined event condition has been satisfied. Other embodiments may be disclosed and/or claimed.
