Out-of-Box Experience

ES120 somatosensory screwdriver is designed andmanufactured by e-Design, and the main highlights of this screwdriver are itsexquisite metal shell, OLED display, somatosensory turning and multi-torqueoptions, these highlights are integrated together into a piece of craft-levelmini power tool.

Performance Parameters

With weight of 130g, built-in 3.7V single-celllithium, no-load maximum speed of 170r / min, torque up to 2.5 / 20kgf-cm, useof 4MM hexagon bits; and you can manually upgrade the firmware.

A portable storage bag is presented with the tool,ES120 can just be fitted in. Only the space for carrying screwdriver bits is alittle less, there is still space next to it, and you can DIY in spare time, itis expected to insert 10-12 screwdriver bits.

Appearance

The body of the tool can be described as exquisite,the hard texture of alloy shell is better than that of aluminum, making thetool more durable.

Let's get into more details of the appearance, itsreticulate knurling plays a non-slip role and ensures that the hands won't bepricked. The performance of ES120 in the details is not inferior to thehardware of other major brands.

On top of ES120 screwdriver,is the charging interface and also the data interface, the firmware of thescrewdriver can be updated through connecting to the computer. If there isrequirement for an upgrade, you can connect the ES120 screwdriver under offstate to the computer, press and hold the ES120 button to copy the firmwareinto the USB flash drive.

The specification ofbit socket is 4mm, which can be compatible with a variety of 4mm hexagonalbits, with strong magnetic adsorption. With self-locking device, you canmanually use the screwdriver, in case of firmly secured screws which cannot beloosened under electric mode, you can manually loosen and then enable theelectric mode.

Functions

What is distinguished about this screwdriver is toachieve the direction and speed control through the built-in gyroscope, theadvantage is that it is unnecessary to set a mechanical turning switch for thetool body, all the functions can be operated with a single key, and can achievethe magical somatosensory control effect. Press the button for three times topresent the 5-speed option menu, where you can adjust the torque, commonly use1, 2, 3 and 4, Gear A is for the automatic mode, the speed of the screwdriverincreases as the rotation angle increases, the speed of screwdriver bit can becontrolled through slightly turning of the tool body.

Somatosensory Control for Direction of Rotation ofBits

Only by pressing and holding the button of ES120and turn the screwdriver itself as rotation axis, the rotation direction of thescrewdriver will be consistent with the direction of turning. As for thetriggering angle of rotation, the minimum control sensitivity is 2 degrees,that is, as long as the screwdriver is turned for 2 degrees, the controlcircuit can be triggered.

ES120 screwdriver provides a customization for thisfunction, access to the USB data cable under off mode, short press the button,the computer will identify the USB flash drive; open config.txt in the USBflash drive, showing the following contents:

StartAngle=2 # (2~10) start angle of braking, if itis set to 2, then the press button will rotate for 2°

Gear=4 # (0~4) The set gear upon starting of themotor, 0~4 corresponds to Gear A~4

MotoTimeCont=0 #ReadOnly Motor use time, cannot bechanged

Ver=1.1 #ReadOnly Version number, cannot be changed

The following figure shows the control for turning,the gestures for control in the figure changed more obviously, this was tobetter demonstrate the control effect, in actual use, you only need to turn thescrewdriver very slightly, the response will be very sensitive. Thisscrewdriver has a memory function, press and hold the button under the standbyinterface, keep stable for half a second, the screwdriver will rotate, and thedirection of rotation will be that of the last use; this function is veryconvenient for the users of frequent use of the screwdriver.

Somatosensory Control for Speed of Bits

Gear A is for automatic mode, in addition toachieving somatosensory control of rotation direction, it can also achievesomatosensory control of speed, the main role of this function is not forshowing off, it can not only guarantee the speed of driving, but also canprevent the threads of screw from being broken.

Look at the demonstration in the figure, although theaction is still exaggerated, the actual rotation sensitivity is of about 2degrees. The speed control process is very interesting, from slow to fast, youcan do whatever you want, it is more like manually turning the motorcyclethrottle. When the ES120 is turned at the slowest speed, the rotation speed ofbit is adjusted to the minimum, and if the speed of turning is increased, therotation speed of the bit will gradually increase.

If you want to useES120 smoothly, the two screwdriver bits presented together with the tool arefar from enough, it is necessary to buy a multi-function bit set kit.

The genuine parts areprecision bits of "Labear", a Taiwan brand, made of 8660Nickel-chromium-molybdenum alloy steel with high hardness, the bits areslightly magnetic, such magnetic may come from part of the screwdriver bit basewhich has strong magnetic force, in short, it is easy to use, you can use thisfunction to absorb screws, the absorption is good, it can help you save timeand effort.

Purpose

With the multi-function bit set kit, ES120 can almostbe used for the entire digital sector: the lens, the players, mobile phones,etc., ES120 can be used wherever there is a screw.

Here are a few commonapplication scenarios to illustrate the use of this screwdriver, the majorityof mobile phones on the market, including Apple phones, most screws for mobilephone assembly are TORX screws, such screws are more sophisticated, although ofsmall size, but can have around 20 threads, to tighten or loosen them manuallyone by one would be quite laborious, especially for maintenance professionals,handling such screws every day can be considered as physical labor.

Phillips screws onmusic player can easily have broken threads, especially in case that thescrewdriver bit is harder and does not stop rotating in time, the more powerfultorque will drive the bit to rotate a few more turns, which may destroy thescrew.

As for the slot headscrews on electronic watch, the advantage of having many screwdriver bits canbe reflected now, no screw cannot be unscrewed, such screws are of very smallsize and are also used on the glasses.

Potential Mining

As for the electric screwdriver, torque is the datathat will be most concerned about; the data parameters proclaimed by themanufacturer cannot well express its power, the torque value cannot be learnedthrough tightening the screws either. I personally feel that drilling is theintuitive method to show and verify the torque.

As differentmaterials are of different densities, the minimum torques required to drillthem are also different. The following example is to drill wood with ES120screwdriver, as the is very short, we find a paint brush with diameter of 1 cmto use for this test, the brush holder is very hard, ES120 can easily drillholes on the wooden brush holder.

Drilling Iron Sheet

It is also very easy for the screwdriver to deal withmetal can, adjust the torque to Gear 4, press the body of the screwdriver with force,in the whole process, accompanied by the friction noise of drill bit and metalsheet, the drill kit is rotating, while the motor does not enable overloadprotection due to too much resistance, it can be seen that Gear 4 is enough tocope with such metal sheet.

Double-sided PCB Multilayer Circuit Board

As for DIY of circuit board, you need to manuallydrill holes in the CCL. ES120 can easily drill through such double-sided PCB ofhigher hardness, which shows its significant motor performance and drivemodule, the quality of the tool is very applicable for the DIY enthusiasts.

Conclusion

Each tool will have its specific use, and the use ofES120 is only targeted at small size screws, it is suitable for assembly anddisassembly of a variety of sophisticated small equipment. It has the followingadvantages: small size, high torque, exquisite shell, adjustable torque andsomatosensory control. Hope thisscrewdriver will become the classic in the classic DIY tools.
