ES121 Motion Control Cordless Electric Screwdriver

ES121 Motion Control Cordless Electric Screwdriver


The ES121 smart motion controlled screwdriver from e-Design is definitely one of those products that you don’t necessarily need, but one that you wouldn’t be without if you have it. For any serious drone builder or RC modeller, the ES121 could save you a surprising amount of time changing screws and generally fixing things.

Built into the screwdriver is a 3-axis gyro, which detects motion, enabling you to control it with just a slight turn of your wrist. To use, simply press the screwdriver firmly against the screw, hold the power button and turn your hand slowly in the desired direction as if you are turning the actual screw. Turn it to the left and it will spin to the left, turn it to the right, and it spins right. The more you turn your hand, the faster it will spin which makes using it very intuitive. The screwdriver has four torque levels and an automatic mode where it will increase torque as necessary to turn the screw up until it reaches its maximum and then stops.

The ES121 isn’t cheap for a screwdriver, but it’s certainty a quality product and addictive to use. It has a slim CNC'd 304 stainless steel body about the size of a marker pen, with knurled grip for comfortable holding. It’s also equipped with an OLED screen for a bright clear display, which shows the working status, battery level, and load of the driver. It has a built-in 300mAh battery for wireless operation and fully charged it will give up to 60 minutes continuous use, which is plenty for a normal day’s usage. Recharging it is straightforward, it’s USB powered so just plug it into a computer or phone charger.

This is the upgraded version from the original ES120. Its drive motor is fitted with a 1:64 reduction gearbox now delivers a faster rotation speed up to 380 RPM, making it even faster to use. It also comes with 16 high quality alloy screwdriver bits, which include Philips, Slotted and Torx Hex’s.
