My last video about the ES120 was very well received, so the manufacturer sent me the new, upgraded version, too. e-Design is known for the coolest open source gadgets like the TS100 soldering iron, different oscilloscopes and now the wildly popular motor screwdrivers!
This upgraded version is called ES121 and it has a few more tricks up its sleeve than just a different gear ratio. - วิทยาศาสตร์และเทคโนโลยี

“I don’t know what units I’m measuring but it’s a direct comparison”
Pretty much captures of the spirit of engineering.
I came here with the state of mind that I do with any review video but was completely caught off guard by the fantastic gem this is. This guy has one of the most entertaining personalities! Impressive intellect. The accent paired with the delivery of the jokes cracked me up! Bravo sir, bravo.
Just stumbled upon your channel, Marco. Your 1.3kW precision screwdriver delicately screwing the self-tapper into place, was so impressive, how could I not subscribe.
Ha, that intro had me cracking up. Was searching to compare the two models. Glad I found the channel.
so much videos from you lately, amazing
Must be trying to match up with the 4000 hours and 1K sub quota
If I had zero interest in the subjects of your videos, I would still be subscribed and still enjoy ever moment of them.
Great in-depth review!!! Love the Bearing test.
Ha! This vid made my day! Love the drill press -- thanks for the pointer to thingiverse -- I might have to printify that.
Dude that bearing test was.......speechless! Awesome is an understatement! Pretty chill, man, pretty chill
Excellent and very entertaining analysis. Thank you.
Good to see you are getting a few products to review. They come across fair.
Getting so much content lately. Its great.
That sense of humor! 😂 Subscribed.
What, two videos of my favourite german electronics enthusiast? I must be dreaming!
nichtdu23 fascinating voice and accent :D
Congrats on 30,000 subs!!
Yay, thanks!
two videos in one day?! im hyperventilating in bliss :O
now THAT'S what I call a review. Not thoose cookie-cutter "reviews" where people are merely advertising the product. Props bro
I love your comparisons
Brilliant video!
Two videos in one day hot damn
Your German accent is delightful! It confers your videos 50% fun and 50% seriousness/precision, it's very funny! Quality
Hey marco! i would love to see a tour of your shop, and some tips for what lab machines to buy/build as a begginer
the MOST ADORABLE DRILL PRESS, I want fifty
such a funny and informative review!!!
Wow 625 torque units! Dang! I don’t know if I could settle for a measly 500 torque units.
They're measured in ATUs, otherwise known as Ambiguous Torque Units. Obviously ur not an engineer...
Though he could use a regression model to convert it to Nm2
625 potatoes of torque.
@@MadJDMTurboBoost ATU, the international idk torque unit. Love it.
Imperial equivalent is a cup of tea per square inch
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.
Great video.
I really enjoyed the side tracks
You make Interesting item even more interesting
Good stuff!
Had to get One Just Soo Cool...
I like your review
That's it! I'm buying it!
100 Dollar?! I have to find some new projects with a lot of screws to justify a purchase like this.
J Bender It's not meant for the average tinkerer. It's for someone who installs/removes a lot of fasteners. Like a cellphone repair shop, or someone self-assembling their own kick starter project product, etc.
It’s a luxury tool, not a necessity tool.
Well for 100$ it is more like a "I Need it sometimes and I want it" tool@@49684
@@LenniL-ob4ll Electric tools cost alot. I think it's a luxury.
@@LenniL-ob4ll 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.
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.
What? I just finished watching your microscope video. Great :D
I like your nice and small 3d printed drilling machine
Спасибо! Интересные у вас ролики.
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
Your talking accent is very cool!
I think this product is featured in the "Mission Implausible | M1 chip | iPad Pro | Apple" video!
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 :-)
Lucky
Is that supposed to say 1:44 ?
@@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?
@@davybloggs1564 the bearing set up has been migrated to the es120. The only difference now is an faster gear radio.
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!
Anyone else noticed that these are no longer available?
Could you do an update with the ES126?
Love your vids and would be interested in buying one :)
Growmau5 gave up the link, I’m subbed up. Keep on keeping on.
have to know where you got the press and the drill bits, those would be very handy to have...
Can you please give more details on the load cell contraption?
more videos please
I guess customs offices around Europe are still dealing with the New Years Eve gifts-from-China rush :) Good review, not convinced I need one. Better save the pennies for a signal generator
okay maybe a little bit, subscribed.

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.
".. ok maybe a little bit" LOL:)
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.
Where did you get the drill bit for this?? I got one of these from a pallet store for $20 and I would love to have a drill bit for it for PCBs.
0:59 BUT CAN IT DO THIS?! :P
but both the BBBB and the ES121 are significantly cheaper than that chair :)
Another of those gadgets I'd love to have, but I just can't justify spending the money for it to myself.
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.
Both controller boards have ES 120 on them! So, they are the same, surely?
But does it come with an earwax removal accessory?
Unfortunately after almost one year and very very litlle use i have two screwdrivers es 121 that stop function.
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.
Gibt es einen anständigen Nachfolger, den du kennst und schon mal in der Hand hattest? Dieses Modell scheint nicht mehr im Verkauf zu sein.
You can make anything interesting!
You have ways of making it Torque ;) Sorry I'll get my coat
Instant buy if it's brushless.
I have this driver but the battery is garbage now. Any good quality replacements? The usual AliExpress ones probably won't be a worthwhile replacement
0:52 .. why is there no price and warehouse ?
"I don't know what units I'm measuring in..."
Thats what i say to myself whenever i use DT830B multimiter.
That's an american dude when measuring anything mechanical
@@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.
But is the casement made of a prefambulated amulite?
That thing's built like a swiss watch.
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
Hopefully they upgrade the TS100 to have a shorter exposed heating element
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.
Could you compare it to Xiaomi WOWSTICK?
de blue blushless blutality beast
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
Yeh, it's a bit difficult to find: minidso.com/forum.php?mod=forumdisplay&fid=72
Hm, no schematics there ...
It would be cool to make it brushless.
Are you going to be at any event soon? I wanna meet you!
Is is a great compliment that you want to meet me, but I am not very well versed in the ways of human interaction, I am just an awkward dork mostly :-\
Besides this, is there also improvement on the battery life?
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.
Any tips for getting this in the EU (since the customs costs are high)? I didn't find any EU listings on Aliexpress, for example :-) I want this!!
When using Banggoods standard free shipping it takes a bit longer, but usually tax free. Exceptions were reported, but personally I've experienced none.
I will try that then. Thanks!
Any idiot (even I) could take one of these apart.... but taking it apart so that it goes back together?.... that takes a little more skill and effort. Great review!
👍👍👍👍
But is it sonic?
but can it power my skateboard?
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.
Where did you get the drill bit?
Do you have a good source for 4mm hexagon bits that would fit this. Would be great to find good quality allen bit and other special models for phone repair and other
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 any small 4mm hex security bit set should fit.
@@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.
Is ES15 a successor to this screwdriver?
Please show us how to build the blue brushless brutality beast? Could you be so nice?
It's just off-the-shelf parts: Brushless outrunner motor, brushless esc, Conrad servo-tester plus 3D adapters for the bit or grinder disk
Thanks ;)
I think I should try it....
Do you have any Social Media to keep us up to date?
Looks like it's just a hobby grade brushless outrunner motor with lipo battery and an ESC...
Not enough brushless brutality.
4:00 doesn't seen to be straight. Plastic adapter for drill is your adition?
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.
Yes, that's a 3D printed adapter with a crookedly JB-welded drill bit :) I didn't see a better way to insert it
Use your new drill press to drill out a hex head bit in the center. Then put some super glue on the bit and slide it in the new hole.
Hab den ES121 jetzt über ein Jahr. Als er geliefert wurde, hat er 3 Tage funktioniert, dann blieb des Display Dunkel. Bangood schickte mir nen neuen. Vor einer Woche des gleiche Problem. zieht 600mAh, Display geht net an. tot. fand aber auch nirgens nen Schaltplan im Netz. Funktioniert deiner noch oder haste auch Probleme? LG Marc
Hab meinen vor drei Tagen bekommen, ein paar Schrauben versucht zu lösen. Schafft er nicht. Darf man ohne Strom die Schrauben raus drehen? Hab dann im A Modus 8 Schrauben von einem Plastik Gehäuse rein gedreht bis auf Anschlag. Am nächsten Tag machte das Gerät nur noch ein paar Umdrehungen. Egal welche Richtung oder Geschwindigkeit ich wähle, nach ein paar Umdrehungen ist Schluss. Geräusch ist auch etwas merkwürdig kratzig. Schon kaputt? Montagsgerät erwischt? Oder kann man da was reparieren?
Wie hast Du es geschafft das die den austauschen? Ich soll den hier vor Ort reparieren lassen. Hab den dann zerlegt und es liegt am Getriebe. Am Netzteil zieht der Motor samt Getriebe >2A und dreht sich trotzdem nur ein paar Mal. Irgendwas klemmt da.
@@martinnieder4875 der motor läuft super. der zieht 600mA wenn ich den laden will. im schnitt zog er immer um die 300mA. hab Bangood nen video geschickt das er net funzt und die haben mir einfach nen neuen geschickt. hab aber bis heute noch net des fehlerhafte bauteil gefunden. habe aber vom Hersteller nen schaltplan bekommen.
@@FusselCNC So, darf meinen jetzt auch zurück schicken. Aber Päckchen kostet schon 17€ und BG will was mit Tracking. Ein DHL Paket kostet >40€ nach China... und dann darf man nicht Mal einen Akku verschicken. Wie hast Du die Retoure gemacht?
Hab das Teil jetzt doch noch Mal zerlegt um zu prüfen was es denn ist. Das Getriebe sieht gut aus und lässt sich auch relativ leichtgängig drehen. Aber auch ohne Getriebe macht der Motor nur ein paar Umdrehungen. Gibt es dafür irgendwo was passendes?
@@martinnieder4875 durfte damals den alten behalten. Bangood is was retoure angeht echt super wenn man es gut beweisen kann.
How much for the beast?! :D
make a blue brushless brutality beast mini bosch chainsaw
But with no laser how am I suppose to know what wall im making a hole in
What is it with you and lasers? The next video has lasers again, but not dangerous ones, sorry :-\
They are just too good, If it has no lasers, I think where could one go
1.3 kW ?? ...... niceeee!
They sent me a left handed screwdriver
WHAT IS TEH BLUE BRUTALITY BEAST! TELL US!!!!!!!!! AGRH
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
KASA Obviously he did not.
uh ja, das german akzent! I like zat
