Well then, I'm sold! Just reserved one, as I've really been needing an easier document scanning option for years now, and this seems to check a ton of boxes on my wishlist. Thanks for the vid!
LGR here? Thanks for stopping by! Love your channel!
@@CuriousMarc LGR and CuriousMarc. Now there's a collab I'd love to see!!
Wow, thanks a lot for those scans. I'm downloading them right now. Especially the S/360 Manual is full of very dear memories, having programmed for S/360 and later on S/370 and S/390 systems myself for many years. OMG, I feel so young again. Thanks for that!
Seeing that IBM manual sure brought back some good memories of my youth.
This channel remains a joy to have available for all who care to look! Thank you for your work.
Thanks Marc....When I first looked at the campaign there were 12 left. After I finished ordering mine, there were 7 left. Don't wait.
edit: Now there are 16 left. I think I see what they are doing. As the individual units are being sold, they are breaking up the 10 unit groups and selling them as individuals.
It might be as people cancel their pledges more become available
Major cool! - I'm behind the technology by about 20 years!
Wow, thank you so much for uploading that Fairchild catalog!
Thanks for review and catalog scanning! 👍
Great video, as always!
Just checked out the scans and they are great! Some distortion near the binding, but it looks like that is pretty hard to read anyway. A big thanks to all those who scan material for the rest of us to use. I recently received the 1980 General Electric mobile radio price list that I plan to scan to put online. It is in a binder, so I can use the feeder on the printer to scan it.
This has become one of my favourite RUclips channels! :)
Merci Marc pour cette preservation du patrimoine.
Thank you Marc for this heritage preservation.
Nice video. Just a quick thought / suggestion. Does the software detect the page numbers and alert you if you miss a page? For example if you scan in page 1, 2, 3 and then 5 it could give you a warning to say "Hey did you miss off page 4 and want to scan that in before page 5"? If you say yes it can then enable you to scan in page 4 and put it in the right place. It could also have an option to ignore that functionality for the whole document if the page numbers aren't sequential.
If not, it sounds like a really useful feature that should be added to the software.
Unfortunately not... And the software lacks a lot of things...
* we can't resize it
* we can't open folder where we saved the pdf to check it before deleting
* we don't have an auto flattening
* we can't flatten when it's not a book
* a lot of saving options but no explanation and the size is very different
@@NadimOmran If they made that software so you could add plugins in a language like Python then people could add these things.
You can easily replace or insert a scan if you miss one. But it does not check page numbers for you. That would be a cool feature!
An enhanced plugin could maybe enable automatic scanning. You just flip pages, and it just keeps automatically scanning. Scans when motion stops. No need to press button anymore. Scan a whole book faster once software is improved.
Informative and entertaining, thank you for this run through. I am just getting started with my scanner and I was able to get a couple of great tips. This is a pretty great scanner.
I love this channel. Every single video is interesting.
Brilliant review, thanks @CuriousMarc. I have forwarded this to the Australian Computer Museum Society for consideration regarding document archival.
We know them well. They have done an outstanding contribution at not only saving, but scanning and organizing the HP documentation. My restorations owe a lot to hpmuseum.net!
Thanks for sharing all the scans, especially the Fairchild catalogue. 😉👌🏻
As for the hand drawn schematic that wants to curl up, if you can find a piece of polarized transparent plastic, it would do wonders for scanning such documents without reflections.
This is very very nice. I have a few books and 1850s newspapers I'd love to archive. I don't have enough to justify me getting one but this is really cool.
I have been bombarded by their adds lately, but I must say that your review actually convinced me...
Neat! This is considerably neater than the professional (and no doubt much more expensive) book scanners I used at various university libraries only a few years ago! They were still a massive time-saver compared to trying to run multiple pages through a regular copier but none of them was really able to deal with non-flat pages, usually the high parts were out of focus. So the laser beams are a genius move!
I'd be sorely tempted to pronounce the name like "seizure" though, just because you can 😀
Thanks for this! I as well reserved one this morning. Looking forward to getting some documentation digitized and searchable
Just reserved one! I was looking for such a convenient solution for some time, especially triggering the taking of a picture by foot pedal. I'm repairing old cameras as a hobby and today's documentation workflow requires to use one hand for taking a picture by an overhead camera and then get back to my work. Furthermore, I sometimes want to show steps in a manual. Having an HDMI-out perfectly fits with the streaming workflow.
Nice video, very informatic. Thank you a lot!
Thank you! Very informative review!!
Thank you for the hard work 🙏
Amazing technology. Thanks for sharing.
Thanks Marc - just ordered one!
That is really spooky Marc! I had this video playing in the background as I was working on the buzzer circuit on a PCB for my IC Tester, only to find that the SMD footprint for the 2N2222 I am using is wrong in Kicad :-( I was just in the process of rotating the 2N2222 by 120 degrees to make the circuit work when I heard you say "2N2222" and glanced up to see the Fairchild page on that transistor at the end of your video. It's a small world!
Man, I like your style. 👍
Great Video!
You should consider using black backing paper to prevent the backside of the pages to shine through while scanning.
Cool, hope these can save the students' searching time and make them enjoy reading and giving people ideas to solve human's problem.
“Doddly Do”. Funny every time!!!! Thanks Marc
I am really blown away with the accuracy of these scanners. Wow.
I am very, very tempted by this one... I do think the Shine Ultra Pro might be a better option for me, even though it doesn't have the extra light - the price difference is significant enough to make a difference, since I'll only be an occasional user (and the foldability is appealing for the same reason).
I can deal with the glare by adjusting my lighting, but I do wish the SUP came with wifi capability and could be used with my phone or tablet. That would be even more convenient for short projects!
I claimed one of the last on the indigogo!! If you are interested, the discount is massive, but only a handful left!! Thanks for the great review!
The remaining count is fake, part of the scammyness of Indiegogo. I'm replying to you 7 hours later, and it now shows 42 left on the Super Early Bird special. I've seen this before on other IGG projects/campaigns. I'm guessing this is part of their strategy to motivate more backers. FOMO (look it up :-)
This is done by IGG, not the project owner.
@@fliptrontube Ugh.
Very cool product!
2N2222 and 2N2907(PNP) - I've used them for all 35 years of my career - normally just to quick breadboard. I like the old logic books, back from the beginning of TTL where they actually put the entire transistor level schematic for the gate in the data book for the IC. I learned most of my basic logic layout circuits from those books. I still use a 20 FET design for my full DFF only now I work in 180nm rather than the 1.5micron when I started. Thanks for the video.
I have 2 Fairchild Linear manuals 1971, another with smaller but more pages from 1976, a Bipolar Memory Data Book 1977 manual and one 1978 Fairchild Optoelectronics Databook. All originals in good shape.
seems like a useful product.
Interesting product. That will be very useful for libraries and/or museums wanting to preserve old books while making their content available to the public. I wonder why the company needed an Indiegogo campaign as they only wanted a little over $1,000. The interest in the device has generated over half a million dollars for them.
Hey, Marc, the inner margin of a book is called the gutter, FWIW.
Love The Video. This tool is a serious purchase for Preppers like myself who have numerous books and printed information to store in digital form. I'm seriously considering a purchase for myself. Thanks for posting this review.
You can see through the pages!
Pro tip from a manga scanlator: place a black sheet under the page you are scanning to prevent bleed-through.
Many thanks for this great walk through for the CZUR ET24 Pro... I am looking for a good reliable book scanner that I can also use to scan music scores up to A3 size and this may be the right one. Kind regards and blessings, MaxT
Hullo hullo Marc et al...Did you know:
By putting a piece of thin Black paper Behind the page,
you eliminate "Ghosting" from that reverse text/illustration.
And: A rolled document can be straightened,
by dragging over a clean edge, of a table
Greetings "Apolloers" from Denmark...!
We need some old Amelco/Union Carbide catalogs digitized. I have some JFETs from an old Fluke DMM which I can't identify due to the information not being widely available.
The company lists Oxford University as one of their customers.
Definitely looks like a nice bench camera.
The quality of the scans look super sharp and high res from what I can see in the IBM S/360 scan on Archive, but the de-skewing actually seems fairly poor considering the effort they go to with the laser projected lines etc. Probably not 'archival' quality in my opinion, but I'm quite picky :D
CZUR as in tshu:r? No, no, Sir, this cannot be! It must be C-ZUR, as in seizure ... 😛
From what I understand, one major defect with this product and other CZUR models is that the "raw" format is always lossy and artifact-heavy JPEG. Even if you select TIFF, it in fact still uses JPEG as a base and then does the conversion to TIFF so the reason the results in your test seemed indistinguishable is that the TIFF is presenting the already lossy JPEG source. This is backwards and a big concern for me that has made me weary to purchase. We should be able to capture as raw uncompressed sensor data from the camera and that should be the basis for any output format we choose.
in the thumbnail the scanner looks like a grave marker. a little ominous... When I went to look only 18 left. When I had "ordered" mine only 12. Not totally settled on how I am going to use it. Bookscanner, benchcamera, both and how much. I really like the idea of scanning old vacuum tube schematics of radio's and such. And old instruction books on vacuum tubes. Many scans on the web are horrible quality. But getting originals and experiencing the time compared to reward such an effort takes is something I will have to learn
Thank you for this vid ! I ordered one !
And by the way, did you put this Fairchild catalog somewhere online ? :D
Yes link in the description.
Why they do not include/make (something similar to) metal binder paper clips. They hold book flat if clipped on book spine (top and bottom parts) and putting shorter ruler to hold both pages. Off the shelf only good at holding smaller and thinner books spines.
This may allow me to retire my dual-camera book scanner. We'll see how it goes when it arrives. :)
Wouldn't the LIDAR and/or Face ID depth sensor of an iPhone be similarly useful to digitally flatten pages of a book? Is there an app for this already? And if not, why not?
Isn't it a bit strange that the yellow clips can't be removed by the software since the camera originally sees the full image and THEN crops it? I would also think that it is an easy fix if they have the identification marks at the very end of the clip (just cutting the tip off might do the trick as a quick'n'dirty solution)? Maybe just need some firmware/software updates.
This may be a future iterative change they make. Seems like every revision gets better.
there is black-white pattern in that clip, it need point to camera
@@GameBacardi I know, what I'm trying to say is that the camera FOV is big enough to see the markings even if they aren't in the cropped image. If that isn't enough the markings should be at the very end of the clip and not like now with a yellow "unmarked" tip. My idea to just cut the tips off doesn't work since the software would remove that part of the image anyway, software/firmware update is needed but shouldn't be a biggie.
@@bennylloyd-willner9667 'Seeing' is not same to machines as humans.
@@jamesmillerjo I know that (duh😁) , still it shouldn't be that a big software piece to make it happen, wouldn't you think?
Fancy! I wonder if the weird name is meant to be pronounced "scissor", as in the tool you can avoid due to its laser thing. I also guessed wrong the first time how that worked: I figured it was doing essentially 3d scanning, or scanning with a vertical line laser, rather than having a camera that gets corrected on the basis of a couple horizontal line lasers.
I miss those days, the real world of electronics that could be soldered without a microscope. After soldering and replacing +1000 chips, I prefer those of the past. I upgraded the flash in my cars ECU for dual map and it was a challenge with close to "a million" pins on each side. I guess if you learn the new way first nowadays, it all will seems normal.
i agree i can't stand the surface mount crap they have now i will stick with tubes and transistors and some early ic's
Can the camera zoom when using the HDMI output? I could see that having a small document when using OBS a zoom feature would be handy if it doesn't have one already.
That Zelda jazz has some serious Scofield vibes!
Oh, je viens d’avoir un CZUR 16, et c’est un appareil remarquable!
See I would have pronounced the name as seizure :) It looks awesome though. Very useful. Wish the people who scanned some of the old manuals I use had one…
Can you scan larger pages such as 11" x 17"? Also how about scanning 3D objects like your hand tools or electronic parts? Thanks for your review.
Have had my ET24 for about a week now, and while it's fast, it's also a little buggy. In your video, at 9:35, do you see how you have a streaked image in the curve chart right in the center? Mine does this randomly when scanning a book. Haven't found out why it does this, I'm super careful and deliberate when I flip pages and shoot a page. Having to do a "replace" scan from the main window is easy enough to correct the problem, but it wastes time, which is one of the main reasons for buying this type of scanner. Also, when I scan a series of pages, I notice it seems to arbitrarily cock some pages very askew, also making a replacement scan necessary. As slowly and as deliberately and carefully as I position the book, I have not been able to avoid this random skewing of pages. I will say, the OCR is the shining star in the whole package. It does a marvelous job of interpreting the trickiest of text. Thanks for pointing out the "Keep original image" setting when outputting to OCR.
Now that looks like a very useful bit of kit. Good morning all.
Have you tried scanning a PCB front / back..? And is there a workflow for overlaying / registering / 'transparency' to speed along reverse engineering of the 'mystery circuits'..?
I never thought of doing it with this scanner, but that’s a great idea. It’s mostly orthoscopic so I would not have to correct for lens aberrations as I usually do.
Does the OBS streaming requires using the HDMI connection (hence requiring a HDMI capture card)? Or it works via USB like a webcam?
It just used the USB like a webcam. There is even a microphone in the scanner!
@@CuriousMarc Awesome! I asked the same question on the indiegogo page and was told you must have been using HDMI, but couldn't see such a cable on the video.
This avoids the need for HDMI capture, and I really love this.
Considering the secondary usage I can make of it, beside scanning books, I've decided to give my support as well. Thank you very much for your review. I look forward to have mine as well.
LMAO on the microphone. I doubt it's any good. But I'm surprised/impressed. Thank you so much for your feedback.
could you hi light what is the difference between this new one and the 18 model ( other than resolution , HDMI, and the click feedback ) ?
You got it, that’s about it.
Hey CuriousMarc - I'm thinking of buying one of these to scan my original HP manuals (I have a couple that ArtekManuals doesn't have so I need to do the scanning work myself) - Have you used the ET24 to stitch together a super large schematic (These fold outs are A2 or the imperial equivalent in size)? Would appreciate hearing your thoughts/experiences. Thanks - TonyG
No, I don’t think the ET 24 can stitch. I take separate pictures, and stitch them in Photoshop or Microsoft’s excellent Image Composite Editor (ICE). Unfortunately I Microsoft removed ICE from the internet. That was probably one of the best pieces of software they ever did!
@@CuriousMarc Thanks - Appreciate the reply
Disculpa para poder disfrutrar del OCR hay que pagar algun programa?
What happened in the middle of the page at 9:34? Is that a printing error or a scanning error?
Two questions: Do you think the scan quality is sufficient to capture images at high quality? I'm trying to scan/digitize images from books in high quality and that's my main concern. Also, is it possible to disable the autoflatten feature if I don't wanna worry about that distorting the scan?
No unfortunately very bad on photo scanning because of the limit of low dpi (i have the ET18pro)
You can disable flattening. But it’s not good for high resolution photos or art books, even with the improved 24M pixel resolution. This is really for text and graphics.
@@CuriousMarc Thanks, got any suggestions for scanners for my use case, then?
@@MajoraZ Not really, I have not done these. A conventional book scanner with two DLSR cameras and appropriate lighting is the tried and true solution, but that's both large and quite expensive. A flatbed scanner will do great too on photos, but it's slow and difficult on books.
@@CuriousMarc Yeah, at this point some sort of DSLR setup I think might be the best solution, I'm just not sure how i'd make a V shaped cradle or how to make one that would work for multiple book sizes, since depending on the width/thickness of the book and how the spine is bound they may sit differently: A super thick book might not be able to full open up and have the pages lay at a 45 degree angle even in a 90 degree V shaped cradle... and I own a flatbed scanner, but some of the books I own are hundreds of dollars and I don't wanna debind them if possible.
For textbooks/manuals containing both images and text, can the scanned document retain the image(s) on the page, while the text itself be converted into Microsoft Word (all seamlessly)? It is very important that I am able to listen to the scanned text (OCR), using the Read Aloud function of Microsoft Word.
I would like to see if something can be done with pocket sized books. They are small and fat, which do not stay open on their own. Problem with many small trade paperback books, the center is not scanned properly. Sometimes the small space leading to the middle of the book is not even scanned with traditional scanners.
It'd be nice to be able to rent one for like a week or something. I doubt I have enough documents/books that warrant me buying something like this, so scans will never happen... then again, i'm sure someone else out there has them anyway. ;D
Maybe you need some rubber fingers for turning the pages. I used to use them all time back in the '80s in Accounting.
Is this a re-upload? Don’t I recall you already having a video with an upgraded version? Or is this an up-upgraded version?
*edit* clearly the latter, given you mention the breadboard.
It's obviously the up-upgraded version.
Yes the latest and greatest with more pixels and a few refinements, an evolution from the previous one. They added more horsepower ;-)
@@CuriousMarc upped the chooch factor
It didn't take long for this vide to appear on the page of the Indiegogo campaign ;)
The green one is a foot pedal, perhaps
Does Circuit Recognition Software exist as well?
Are you saying I should have SAVED all those catalogs and not start my wood stove with them?
Heathen
I already have 18ET Pro. Do you think I should get this one too? (Because I have many books with graphs and small fonts (for ex. In technical handbooks). Do you think results on 24ET pro would be much better or it is not worth it??? Thank you!!!
Hard to say. I thought the ET18 was already pretty good. It really depends on whether you are reaching the resolution limit on your particular documents. If you don't you are probably fine with the 18. Besides the HDMI port, the only important thing you gain is the higher dpi.
@CuriousMarc CZUR declares the 18ET pro has 275 dpi...for 24ET pro it should be 320 dpi. I don't know how much difference it will make honestly but I hope that graphs and small text will be clear and readable now!
I just bought the 24ET pro..until I get it can you tell me please, for ex. Those technical graphs of minute 08:26 how do they look?? (Are the small text over them and numbers in x and y axis visible and readable?).
Thank you sooo much 🙏🏽🙏🏽
@@ahmedfarrag17 Yes, it did very well with the small stuff. I uploaded the scans (links in the description) so you can judge for yourself.
All the parameters for transistors, that is why they call the '60 and '70 the golden age of sound. You need all of them designing amps and tuners.
Heyyy..did you know that in the recent software update you can scan without the yellow thumb? You can change the settings and after that just use your finger and it will detect it and remove it via software. Try it and let me know..
Really? Thanks for the tip, I did not know. That is pretty nice. I'll try it.
@@CuriousMarc yes..
Also I suggest you for those pages that have text on margins to scan them as a normal (full) image..that you then crop manually. Because if you scan them as we usually do for the rest of the book 📖 (the automatic 2 pages splitter) unfortunately it will conflict with the portion of text on the margin.
Czur? Can I humbly suggest that all of the decent company names have gone. We need to start recycling old ones, I think.
Now we just need to make a page flipper tool
They don't tell you the sizes of the downloadable files - that's not nice! I had to start the download, then cancel it. The Fairchild manual is 534 MEGABYTES! That's huge, too big to store on my cellphone. Fortunately I own a copy, so I have it available at home. But it's a very handy catalog to have. The National transistor catalog is even handier. It tells you about the process they used for each transistor. It shows you a drawing of the die and how big it is. I find it indispensable for crossreferencing a transistor. The same process may have been used for a dozen different transistors, that differ only in the "bin" they were put into after the automated test. Some may be higher gain or voltage than others.
It says the size if you hover mouse over the link. Can't imagine they would have considered somebody using their phone for archive diving.
Looks like it could be used for RUclipsrs to show things if it could make video.
at 5:56, the OCR fails to add the spaces in front of the code... it needs to be made smarter ;-)
It's a limitation of PDF.
@@0x8badf00d argh… what shame
You would think a sheet of glass on top would flatten out a book better, ie, get to the spine.
I think flattening devices can damage the material, it must be costly to manufacture something that flattens it just enough without damaging delicate documents.
I suspect the issue is total scan time. The more fiddling with each page that has to happen the longer the scan will take. A book could be physically flattened with some mechanism, but that mechanism would have to be deployed and retracted for each page.
@@francesconicoletti2547 that too, while it is possible to make a contraption to turn page, flatten, scan over and over it is too costly both in factual manufacturing cost and even more in developing a universal construction for different type of books, brochures, etc.
The time wouldn't be a big factor if it could go through a book all by itself. I think it is, with a few tweaks, an amazing scanner for the cost.
The 'pro' book scanners use two pieces of glass (or perspex etc) at an angle, one for each page. Then there's a separate camera pointed at each page.
This way you get each page as flat as possible, while not flattening the spine.
If you watched his earlier video it showed he first used tempered glass. It shattered in his hands. Made for a very interesting scan.
Now all you need is some bot to turn the pages for an unattended operation.
As my product came with false advertising, I went to the Czur site and there is no linux driver.
FALSE linux driver
I bought a Czur Scanner Shine. The ad stated that it scans books and has the ability to digitize with the curvature of the pages.
Did not work.
I sent a copy of the ads to support and complained that I didn't have access to the curvature system and residual software joins the images and renders the scanner unusable.
Now new scanner promises to be used on linux and I looked for drivers and it doesn't work.
Czur does not live up to the advertisements made. I wasted time and money and support ignores successive requests to fulfill the ad. And scanner ads don't do what they say.
You know what's sad is that in the 70's Fairchild had the pride and wherewithal to properly characterize their components thoroughly. Fast forward to 2022 where everything is digital and trees aren't being chopped down you get transistor data sheets that are less than a single page pf data and no graphs. I'm pointing at you among others with your way over priced reproduction transistors. If you can't characterize your devices I guess you have no standards.
I'm interested in how it compensates for the curve of the pages, or if it does at all. And, I'm sure you can find a 1970 transistor catalog with a wrecked spine for taking apart.
He mentioned that but did not go into detail. It shines three red laser lines across the page horizontally, projecting them at an angle. The camera straight overhead will see straight lines if the page is flat, and various curves if it isn't. The software then rectifies the lines, and that straightens the page text and graphics.
Too bad it's not good enough for picture scrapbooks.
I gotta admit that the scan is pretty darn good, though not completely flawless. Page 2-6 of the Fairchild book has a graph that is flying off the page.
Quick, tie it to the ground!
watch the video properly and you'll see that some parts weren't visible on the book itself as it was too far near the centre.. you can't scan what you cant see.
@I Wilton: Indeed, what happened there? I would need to rescan that page, but since it’s just one of the obscure graphics I think I’ll let it stand for now.
@@funkytransport Look at the scan for the page in question and you will see that what it couldn't scan was pretty much in the center of the page, which it was able to see on every other page scanned.
@@lwilton I think it happened due to use of top lights of the scanner instead of side lights. The light from top lights came down to the page, then reflected back up to the camera and blinded the camera and that's why the camera didn't see that spot.
what is the point of doing this to old catalog
He noted it allowed him to do searches he couldn't do before.
@@toddmarshall7573 fair enough
So much packaging waste. Why cant that stuff just come in the padded case. Why does it have to be in a plastic wrap in a box in the specially cut foam container. Now you cant use the nice box for storage since it only fits the accessory boxes not the actual accessories.
I am #1
You are! Enojoy the 1102 pages of vintage transistor data uploaded just for you.
Why is a 21st century product, not using recycled/recyclable packaging?
How do you know that it is not using recycled packaging?
I think we're worrying a little too much about materials. This device is not cheap, and it deserves to be properly protected in its packaging.
@@robertborchert932 I ordered the carrying case. Will be interesting to see how it's laid out.
