Wow, this looks like to be the most indepth review that I have seen. very detailed. I'm wanting to get one to scan some old history books into OCR Word
Thanks for the video. This is my third campaign with CZUR, going back to 2015. And this is their best so far. I can scan a full book with glossy images with no problem. Never had any trouble with the software, although their interface is not so intuitive to me. Also, I like the small size and light weight, meaning you can pick it up and move it out of the way when not using.
I'm using my ET24 for the first time scanning a glossy book cover and photo album pages however I'm getting alot of glare. How do I eliminate the glare?
Excellent clear explanations. My device arrived a few days ago but not yet had the need to use it. This replaces a Czur Aura Pro which didn't support Linux.
That is really is a impressive piece of kit and looks very well designed, built and doesn’t appear to be lacking in any department. Not something you see in systems nowadays.
I see you had problems with warping too. No matter how hard you pull with the finger cots you can't get it flat enough to work, and the software can't fix it. Part of the problem seems to be that they rely on the laser lines, rather than using software that can do simple corrects like saying "this line is probably straight so I'll use it as a guide". There are open source tools like ScanTailor that do a much better job, but Czur prevent you getting the raw images out so you have to use their crapware. Oh, and it also deletes the raw images when you close the software or switch projects, so you can't go back and improve older stuff or submit it to Czur as a bug report either. Even if it could, the amount of time and effort needed to get the pages flat with the finger cots would be impractical for long books. A simple fix would have been to include a plastic V shape mount for the book, so that you can scan it only half open when warping is much less of a problem. You might have to do one page at a time due to focal length (I guess they aren't able to adjust that to do it in a single pass for both pages) but at least it would have been possible. Did you notice that you can't correct rotation errors either? It only lets you rotate in 1 degree increments, and the error is rarely an exact multiple of a degree. It should do it automatically anyway, rather than making you manually do it. When I asked Czur about it they were not interested. I've come to the conclusion that for non-rare stuff it's best to just cut the spine off and use a sheet feed scanner. For stuff you won't destroy this isn't the solution. The amount of force needed to straighten the pages will damage rare stuff anyway. It only works for things like ring bound book where the pages are flat, and even then it's much worse than ScanTailor.
I have this but haven't used it yet, previously I had a Czur Aura Pro which was ok. From what you say, the quality of this may be worse. Sometimes I buy rare books that I want to scan but not damage and this will do the job. Otherwise I chop off the spine and feed it through a sheet feed scanner. Your experience is still disappointing though. I must check out Scan Tailor, that is new to me.
@@rowdyblakley8669 I think it really depends if you can open the book completely flat without damaging it... In which case you might as well just use a flatbed.
I have scanned hundreds of books in all three methods, hands down the fastest and best quality is to chop the spine and use a sheet feed scanner, (Fujitsu iX500). My least favourite is the flatbed, the Czur Aura experience was actually Ok and the book survived!! My expectations are not high so I guess I will be satisfied with the CT24. Czur are a good company and let's hope they listen to constructive feedback and improve the niggles.
Lol. I also have a hardcopy of Designing with Operational Amplifiers too. Burr Brown and National Semiconductor had some of the best data sheets. So did AMD back in the day.
I've been collecting as many of these reference books as I can from ex-library sales. Nothing being produced like these anymore. Perhaps I'll cover a few interesting designs in future videos with real hardware examples.
I have an earlier iteration of this based on watching a Curious Marc video a couple years ago. I've never used the foot pedal but I'm more than happy with my unit. I unfortunately don't have the yellow page turner page hold opener stabby things.
Good video Steve. Perhaps you could use this to scan PCB's for reverse engineering. Might make it more useful and could be good for alignment of the front and back images.
Yes, agree, much quicker scanning.. Only sometimes, I do not want why, perfectly straight image scan turned and scanned just a portion. Repeated, same result.. Then continued normaly..happened not regularly, unexpectedly, and not too often.. Best scanned, "what normal person" still accept to pay.. Should be nice if some integration with ABBYY ocr could exist... Much sofisticated ocr.. Anyway, you can let the result run on abbyy afterwards..
@LearningandTechnology is it suitable for scanning glossy books or magazines. In reality this is the main reason I want to purchase it, I want to preserve my luxury books and references.
It looks like it was removed in the Web2.0 style update - I have a bookmark to it on the TI website, but it goes back to the home page. Looks like they skipped it with the website update. If you search "Designing with Operational Amplifiers: Applications Alternatives filetype:pdf" on a search engine there are copies though.
Glad that you have one device. I paid for one three month ago on Indiegogo and they still fail to deliver. The package was returned to sender for some unknown reasons, unforunately our post won’t tell me the rason. They keep saying that only he sender will be informed and that I have to contact the sender. Well, I did and experienced the worst. Custom support is completely uninerested in your actual problems. They keep saying that I need to pick up my parcel at the local post office - as a proof they send me a screenshot from a tracking page where you can clearly see that the package is being returned. So I lost my money and have no product. From my experience - their customer support ist the worst ever.
I would love to see how it does if you some sort of book cradle with the stiff spined book. I assume it would handle it well but I would love to see the output.
What's your trick with the finger-cots? I always have problems that the software doesn't recognize the page edge correctly at first and have to do several re-takes. I have been in contact with their support, but it didn't help completely. Otherwise I am also quite satisfied with the scan quality
Not sure if this will help, but I'm not a fan of the finger cots, if you go into the facing pages option, you can have it recognize your fingers & automatically remove them. The software still bugs out occasionally & keeps them in, but I found it does a better job removing my fingers than the cots (which leaves a yellow ghosting effect). (I have the new et24). As far as not recognizing the edges, I'm having trouble getting it to recognize large splash pages that span across both pages & dark black pages. For those, I'm setting it to manual selection & take a photo of both pages. Takes a bit more time, but end up looking better.
@@drawkin_cc I had also noticed and commented to the support that I had the feeling that the finger-recognition works better than the finger-cot-recognition. Therefore I was surprised to see that it seemed to work so perfectly for Steve - though I don't know how much editing was involved. In contrast to Steve I had to pay for my ET24 and not produce an advertising video... But it is really a good scanner!
@@uwezimmermann5427 Yeah, I find the software a bit hit or miss, but mostly hit, so I'm pretty happy with the scanner as well! Hopefully software updates will fix the finger-cot issues. :)
It worked straight away for me, no issue (no camera/editing trickery). I missed the finger detection option, but I didn't have to fiddle about to get anything to work so didn't dig further than I needed to. I didn't try it, but I could imagine if you happened to shake whilst the image was being taken they wouldn't be detected properly.
I'm using my ET24 for the first time scanning a glossy book cover and photo album pages however I'm getting alot of glare. How do I eliminate the glare?
Quick question. At 23:32, you can see a single 2 pin connector feeding into the board with the buttons. How did they the signal from four buttons over that single two pin connector?
@@supernumex is that a common thing? It would make sense since it would save money on manufacturing not needing the extra connector and would only require one pin on a μC microcontroller?
@@justcallme00oogy It is a cost saving measure if you want to only have a small number of buttons. Downsides are you need an adc on your micro, doesn't work as well for lots of buttons, quite slow, issues if you press multiple buttons at once. Otherwise multiplexing an array is not too difficult and only requires some digital pins.
It's "Designing with Operational Amplifiers: Applications Alternatives" by Graeme, Jerald G from 1976/1977. Steve said somewhere in the video that it was available online on TI's website, but I could not find it there... There are tons of second hand copies on sale though, if you google for it.

Today's novelty is tomorrow's landfill trash. And kind of expensive at more than $600 USD. I see dozens of free flatbed scanners at the recycling center which work fine of scanning a few pages here and there. I took one when my AIO printer broke and then later recycled it again when I fixed my printer.
Good luck scanning a whole book with a flatbed scanner... Center of folds will be dark, it will take days, it's clearly not the same segment... You mention a few pages here and there... Nobody's gonna buy this device for scanning a few pages here and there... We're talking about books here... Don't buy a toaster since you can toast bread in an oven... Don't buy an oven since you can toast bread with a campfire...
@@trollenz Who ever needs too scan a whole book? Anyone who's watching this review? If I ever did, I could buy the book 30 times over for what this scanner costs.
It's pretty good actually. I will be looking after this one as it's a lot quicker to use than a flatbed scanner. The only possible issue down the line is software support.
Got mine a few days ago. It's garbage tier. The output is "better than nothing" but nowhere near what I'd consider minimum quality for scans of books. The software is particularly bad. It crashes a lot, and the UI is awful to use. It doesn't DPI scale, the mouse wheel doesn't work in many places, drop-down option boxes break if you move the mouse off the slider. At least on Windows, have not tried Linux. The worst part though is that it just doesn't fix the page warping. It tries, but it almost always fails. How badly depends on the book. Paperbacks are basically impossible to scan. Even hard backs look terrible towards the start and end. It also screws up colouring and shading in the process, and rarely crops correctly. You can improve it with a lot of manual labour, but on a book with 1000+ pages that's ridiculous. Czur support are hopeless. They can't help because the thing is just crap. I'm trying to get them to take it back but they don't seem interested. Some sample images here: diybookscanner.org/forum/viewtopic.php?f=14&t=3696
I have some problems with the finger-cot identification, but I really do not experience any of the other problems with the software that you mention - and I am also using it under Windows. And unlike Steve I also paid for mine, haven't regretted the investment.

Nice you got the ET24, I reviewed the ET18 earlier in the year, it’s a really nicely done unit, I couldn’t get the auto scanning to work in my case.
Seemed to work well for me on Windows 10. It would be nice if it had some kind of indication when it's about to take an image though.
That is really is a impressive piece of kit and looks very well designed, built and doesn’t appear to be lacking in any department. Not something you see in systems nowadays.

This seems to be purpose built for archive digitisation. For a museum or the archiving organisation it would be vital.
quality is not up to par for archival or museum. resolution is far too low, and distortion is high. this is for casual low quality digitization only.
