Its not an upgrade, just a different gearbox ratio. I've emailed the maufcturer asking what else the so called upgrade is.., here's there reply... Hi: ES121 is not upgraded of the ES120, I don't understand why the agent said it was "upgrades." ES120 and ES121 are different from the gearbox, ES121 is 1:64, and ES120 is 1:144. The other is the same, the motor speed is 25000rpm. Ive now got a es120 on the way :-)
@@intbn No, It is 1:144. Also, our friends review tells us that it has new/different bearings - the ball thrust bearing for example - what did the 120 have?
I would just like to clarify that the new version of the ES120 has the updated bearings. The only difference is the gear ratio. The new version comes in packaging like the es121 instead of the older cardboard box.

@@GeeDeeDee A luxury item is any item which is neither a commodity or a necessity. A 100$ relatively low torque screwdriver fully classifies as a luxury, especially when there are much cheaper comparable options.
Love ur vids! Just a tip, u cannot use a load cell like the one in the video for measuring the torque, u r measuring kind of noise and structure deformation but not well correlated with the torque. U should put a leverage on the drill and let it press down the load cell, then multiple the force read for the leverage length. The load cell is engineered to filter the torque
Das Ding ist echt geil! Danke für die Empfehlung! :-) Wenn man das per USB an den Computer anschließt (in meinem Falle an einen Mac), dann wird ein USB-Laufwerk mit 2,1 MByte gemounted. Vermutlich ist das nur für Firmware-Updates. Schade, dass das nicht größer gemacht wurde. Man hätte dort Schaltpläne rein legen können.
Seeing as you did not realise, I designed this specifically for use with mobile phones and tablets - nothing other. More than adequate torque to handle the needs of a daily repairman. Not designed for anything further such as a laptop
Hey Marco, Just received the es121 today from good ole banggood. I charged it up, and it seems pretty weak. It couldn't unscrew a inexpensive plastic led light even after manual loosening. Am I doing something wrong? I bought this after watching your awesome video ;) Thanks for your help!
jamble7k of course but will need to be charged every ten minutes and top speed is 1 MPH Ok I really don't know the limit, but it should make the skateboard move.
Hi Marco. I know this is a fairly old video, but I wanted to pick your brain on this screwdriver. What type of grease would be best for the planetary gear assembly? My ES121 had an issue where the gearbox was slightly binding causing the software to think the screwdriver reached maximum torque and would shut it off after a revolution or two completely unloaded.
How about a torque test based on the basic definition of torque: Screwdriver directly turns a lightweight arm of known length with a movable weight. Measure ability to lift arm with by turning screwdriver, and you'll have a good measurement in kgm. Multiply by local gravity for Nm.
I haven't tested this, because my batteries last for days on both screwdrivers, but I think there might be a slight improvement, yes. Because of higher speed, the motor is powered for shorter periods of time. When considering screws with friction, they'd probably have the same battery life.
I received the ES121 today. The battery was completely dead when I got it and it didn't come with the portable pouch as in the description. Now when driving and tightening a half dozen screws or so on any setting it just quits working. I can get it to work again if I plug the USB in. Going to contact seller to exchange it or get a refund. I wonder if all ES121 have the same problem or is it just a random thing.
You have connected the load cell wrong. The screw should be perpendicular to the drilling axis of the two large cavities. That is the direction in which load is designed to flex. There is a sticker on the load cell which indicates the direction/axis in which force should be applied.
I appeal to the author of the review. Is it possible to use this device for threading (1-2mm)? Is it possible to control the forward stroke and reverse so that the stuck tap is not broken.
@@floriandaler5327 yeah it's pretty weird over here. I inherited a bunch of imperial tools from my family. When I go to work on something built within the past 20-30 years it's mostly metric. Even the supposably "domestic" vehicles and tools. OR half the bolts are Metric and half are Imperial! Everything is mostly made in China now.
300 mAH sure isn't alot of juice , I wonder if the battery can be replaced with a higher capacity one, I'll have to see what is available for that size
from what ive read, it last for ages as it is. not much point in making the whole thing more expensive just so you "only" need to recharge it once every two months instead of once every couple of weeks.
Jim Steinbrecher yeah, I have no idea y I wrote that comment in today's context, I have decent enough analog lol screwdrivers, for that kind of money I decided to just buy a genuine hakko 888d station instead of the cheap knock off from Chinese sellers , this powered screwdriver is a expensive toy for someone like me who is on a budget and needed a upgrade to his soldering iron regardless , being a financially responsible adult sucks major.
Putting a higher capacity battery wouldn't make it more expensive. It's $100-120, and the battery costs them around $0.25. Since it is not a Li-ion battery from one of the 4 big producers, but it's from a no-name Chinese company, (so it's probably more like 150-200 mAh.) it is really cheap. So even doubling the BOM cost of the battery would only add
Yeah, the second I saw that, I was going to ask for a measurement on the run-out. Weeble wobbling all over, just asking for PCB carbide bits to break :( Maybe the radial bearing doesn't have a proper seating and/or it was misaligned during the assembly? Generally there should be at least two radial bearings on the shafting of any drill-esque machinery (at least according to the application notes from precision bearing companies like NSK). The one closest to your bit-holder should be super snug between the shafting and housing, and the second alignment bearing at the opposite end should have some play to accomodate for misalignment in couplings and/or thermal expansion/contraction.
Hi Marco The ES120/121 are advertised as open source / creative commons. But I'm unable to find the source files for this project(?) I would be very interested in the firmware and the schematics since I want to try different control methods for the ES121. Thanks

I like the TS100, but it has a few shortfalls. The reason I still prefer my trusty Weller WHS40 is the cable. On the TS100, the included cable is very stiff and short, making soldering small parts a bit uncomfortable.

Fotograf - you can buy them anywhere - any good DIY store or hardware shop. That's one reason why this is better that the AtuMan E3, as that device uses propriotry bits, only availably from them = dumb idea.
@@davybloggs1564 Yeah, but I did search on ali and other shops and I can`t really find any good range of different bit type. I want to find square, triangle, star and other for phone repair, and also small nut bit for unscrew/screw nuts.
@@IBICO74 If your still looking, check the Xiaomi Wowstick, the bits for that are sold separately and are the same size (4mm). They offer a lot of different bits.
A+ but the torque test needs to be supported in a jig. As it stands, your assembly is transfering torque from the screw, to your metalic unit + strain gauge load cell, and then continuing to transfer torque to your arm (that is, your human arm, not a torque arm ;)). A substantial amount of the motors generated torque is transfering into the pivot of your assembly/into your body. Placed in a vice, you can do multiple runs against the same torque reaction, limiting the variance. (Alternatively, if you want to have multiple runs gapped between time, a 50 kilogram weight placed on your assembly should be repeatable between test setups, (which is not the case for clamping in a vice, unless of course you're torquing the lead screw of the vice itself down with a torque wrench.)) Also, this goes without saying but there should be an equal amount of pre-load for each test. (An easy way to do this is: take a piece of .001mm feeler gauge (or shim stock of a hardened metal), insert the feeler gauge as shim between the screw and the assembly, then screw down to 'hand tight'. Mark both the screw and the assembly. Remove the stock. Each time you set up the rig, the screw and assembly should line up to the demarcated points, so your driver is consistently working with the same (negative) preload, so the inertial force variance is limited).
The second paragraph, yes, I agree. It's only moving as far as play in the mechanical parts allows. But I don't agree with the first paragraph, no torque is applied to my arm.
Andrew Nambudripad Him moving his had and the entire unit, everytime he activates it, is confusing. The way it is steeped into that fixture shows that he should be able to activate the screwdriver without holding the test device at all. Either way, I don't think it is transferring torque into anything except the clamping band and the load cell.
