Ever heard of an open source screwdriver?

[Nusa]

Extreme teardown of it coming?

The first video in the thread did that already.

[Mr.B]

Initial impression :
Look & feel is nice, but would have been better if they could have incorporated internal bit storage
Button feels like it's in the wrong place - should be further down - you need to hold it further up than feels natural
Too much free-play when shaft is stationary.
I eventually discovered the torque-stop setting by triple -clicking. Seems reasonable but settings are the wrong way round - 1 is strongest, 4 is weakest. Unexpectedly sensible in that torque-stop only applies in clockwise direction.
A bit mean that they only incude 2 bits.

Mine arrived today.
I agree with Mike on his comments.

I have upgraded to firmware version 1.8. (from 1.7)
Version 1.8 has the following torque settings: A, P, 1, 2, 3, 4
According to the manual 'A' means automatic, and as Mike said above the numeric values are various fixed settings - backwards.
Does anyone know what the 'P' setting means? It is not documented in the manual.
Not sure if version 1.7 had the 'P' setting as I upgraded the firmware before doing anything else.

Only manual I can find is here: http://www.raspberrypiwiki.com/images/9/95/ES120-USER-MANUAL-EN.pdf

Regarding bits - I'd recommend getting Nanch (just google it with pictures) screwdriver set with bits - it's S2 steel long 4mm bits of the best quality I've seen. Use it all the time and I think it's a must have.
So, included bits with any screwdriver is something that is left in the box and never used.

Not being disrespectful, but I'd like Mike's thoughts too. As well as others such as AvE if they got one.

That's it; now I've heard everything.

Sounds entirely sensible for high-reliability industries, so you can have a record of every fastener being torqued correctly.

In industrial applications, I expect the worker to cope with wire. No reason to pollute the ether!

For bits, I recommend the 4mm range from Wiha!

[Neomys Sapiens]

The one thing that is really putting me off: why did they have to make it magnetic?
Spring action of a compression spring makes a perfect holder for the bits.
And I will not have my precious 4mm bits magnetized,as this could well disturb lots of things, like galvanometers, RF components etc.

I really like my Black& Decker Gyro power screwdriver.  Motion sensor to detect rotation direction and speed.  I have a little Jacobs chuck for it and use it for tapping holes as well as for driving screws (and sometimes for drilling as well).

Ooh, you can end up in Machinist's Hell if the God of Lost Chuck Keys hears you saying that. 

[In a baptist minister's reciting voice] And yea, Cockford said unto them: Thou shalt only tap with a lathe or a proper tap wrench, and only after applying adequate lubricant. Woe unto them who believe that they can hand tap without a tap guide, and an especial hell awaits those that tap with hand held power tools, and there they shall spend eternity extracting broken taps from crooked holes. And thou shalt chamfer and deburr all thy holes, lest the wrath of Murphy fall upon thee. Amen.

Would be a pain of you're working around a large structure.

I meant for data readout, not for power. If working in such a large structure, the wire would go to the same portable/wearable device that is identifying and keeping track of the points to be a-screwed.

After reading this, I found this kit: https://www.ebay.com/itm/132343724229
I think it might have been mentioned somewhere here, but didn't find it again, but it arrived today, very very nice kit, atleast now I have bits if I should buy that screwdriver.

Well, I have bought this one earlier, so I had more bits than I need: https://thepihut.com/products/ifixit-universal-bit-kit

Hi,

BTW, new version of ES120 - ES121 released. Unloaded speed is 340 RPM versus 170. Torque is lower, of course. Basically - change of gear box.

Review video:

Still seems slow. I'm sure I can easily twirl a regular screwdriver faster than that with two fingers around the thin shaft. The real value seems to be in the torque setting - good for assembling stuff.

I wonder if they'll ever come out with a version that has a switchable gearbox, basically like the ones found in better cordless drills. Maybe it can even detect when it's applying high torque and automatically switch to the high torque mode. Or somewhat easier to design could be a miniaturized impact driver powered by a tiny BLDC motor.

[Mechatrommer]

thanks now i can save the half naked porn into my electronics folder video's archive (no actually, just a joke, i have alot better than that). btw it seems too clumsy to move the unit around while unscrewing, but i guess its for the purpose of the demonstration. in real life you'll unscrew (expose) more than you ever wanted..

[NiHaoMike]

Keep in mind the "model" (who doesn't call herself that) is skinnier than 99.9% of engineers. (I literally only know one engineer - out of the thousand or so I have seen in real life - who is even skinnier than her.) Hence why heavy objects seem to be particularly heavy for her.

At the risk of going off topic, I'd like to know where you got even "better" videos of "models" working on electronics stuff. The closest I know of was one of my friends "live streaming" how to set up a Bitcoin miner back in the day and how to use a Bitcoin wallet to send her some tips. (I didn't actually see that, just heard about it.) Unless you're saying that she shows off too much and you prefer a more modest presentation.

I think using it to take apart a 3D printer may have been a little outside of the scope for intended design. Out of all the review videos I’ve seen, and being a creator in that genre she has never came up in any of my suggested videos. How did you find this video, with a specific search?
New logo for her might as well be “Don’t turn it on, or you might have to take it off”
No thanks, I would rather see the product and it the person in a review.

As for the uses, I’ve seen a lot of people cover different reasons on why they might buy Ken, and maybe not buy one. I thing about it last year when I first saw it. But I went the cheap rout as always that usually ends up in a more expensive rout in the long run. One from harbor freight, one from Walmart becjase it was in the shelve, and a few others that hit the trash bucket.

My goal was originally to be able to do tear downs and not have my hand cramp and twist in weird positions. Something that happens during the recording (more editing time) that I end up deleting in the end anyway, or I end up suffering later that day/night. So for the person with health issues like a “Stiff Person Syndrome” (SPS), carpal tunnel of the wrist, arthritis, or maybe worse and loss of some fingers I could see this being a way to still do a hobby and assist.

Well after a year, I decided to ask for a ES120 (coming soon), I guess I’ll find out if it can help in this area. I gave up on trying to do tear down videos from it causing my fingers to do some weird contortionist bends and lock ups. Maybe this will help?

But I’m always on the look out for new technology, lighter soldering irons, anything that can help so I won’t be forced to give up another hobby. But anything labled as medical assistance and this screw driver would cost $1,000 in the US. So I try to stay away from these “medical” reasons for buying or using something in reviews. I’m not in a rush so I don’t see the need for the ES121 and won’t be assembling a 3D printer. It’s more for small electronics with a lot of screws, the repeating of multiple screws is what screws me in the end.

She's a friend of mine (online) so I get early notification. Keep in mind she's more of an artist than an engineer.

It does sound like the ES120/ES121 would be a good solution for you, but have you checked with your doctor if there's a cure for your condition? Fix the real problem, not work around it if possible.

Mine one came broken, I opened the pack and touched the button and ? no, it did not work. I applied to seller many times, and they always say "please change the firmware" even the device is not responding to a charger or a pc usb port. $80 is gone to the waste. sorry, I am so sorry,

Hello all,

did anybody do a comparison of 120 vs 121?
I saw the youtube videos from the german Marco Reps, but the question was left, why it has just a bit lower torque but much higher speed.
Should one get the 121 because the torque is not that much lower?

[digger]

entertaining vid, but it is kind of a failure of a review.

you show plenty of unscrewing but little screwing. you show that torque adjustment exists (1-4 and auto), but you never give us a demo of this. why?
i would try to show how it works for various kinds of common fasteners, including screws going into plastic (where overtightening would ruin the plastic). can you get useful and somewhat reliable/repeatable torque for common applications?
