Make a UV PCB Exposure Box Using an Old Scanner

[@svenpetersen1965]

I really like the idea. 12 years ago, I gave away my uv exposure unit, because I thought, I will not use it anymore and now I would like to have one again. I have also thought of modifying a scanner. I was not sure, if I wanted to use uv tube lamps. The uv led strips might be easier.

Ωραία κατασκευή. Μπράβο φίλε μου! Θα την φτιάξω!

[@lobotommi787]

nice gadget ! in my lowbudget scanner are working tubes from a "Toaster" Ballasts from dead energy safing lamps, and time makes a 555 ;) I recommend small neodym magnets for top cover improving "gap less" between template and laminat !

[@Error42_]

Nicely done, very neat and great use of existing buttons. I was thinking of making a back light box with one, I was wondering if anyone else had done anything similar :-)

[@abbasi5757]

Perfect

[@rocr62]

Great video. Thank you. I'm building mine now.

[@mvssarma3387]

Many thanks please

[@PraveenKumar-yv9ex]

Good

[@AnilArya51]

Can you make an upgrade d version that can expose both sides of PCB same time

[@desmondrice1756]

That from experience is the ONLY CORRECT way to produce pcb. The iron on toner transfer is just a gimic.

[@benhummer185]

My UV exposure made same way :)

[@g-r-a-e-m-e-]

Nice job.

[@chizknocka]

Very nice man! I think I'm going to build this. This method seems more accurate, and smart than the ol' iron/transfer paper approach. What transparency paper do you use? and would this exposure box work with an ink, or laser printer?

[@stephenyork7318]

What’s the wavelength of your led strip?

[@YO3HJV]

So? Did this work? I want to build something similar but I am afraid that the ordinary glass block UV light...

[@iamjackalope]

Shouldn't the pad on the lid be covered in a black cloth like crushed velvet or maybe felt? You want to try a limit any stray light reflecting off the lid don't you?

[@arunprakaashmurugesan6611]

Nice video I really like it. Upload testing video then only I can make similar one.

[@customelectronics]

What exposure time did you need with this? Thank you. Mike

[@paulg.3067]

I tried something similar with my old lide30 scanner. I also used UV-Led's, those 3 connected ones, max. at 405nm from Ali... I used 120 leds on an ~A5 area... powerdraw ~2.3A@12V... The result was the whole plastic bottom warped upwards because the LEDs where getting so hot. And second, I was not able to expose my bungard 10x16 pcb. I tried 3-5-12 Minutes, nothing worked! Maybe the glass of the scanner blocks all the UV...

[@paulg.3067]

I had a bad PCB... it just works fine with another new PCB...

[@ankitshah1334]

Can we use UV & white lamp together to scan documents

[@prinjess9076]

Very nice job. I cannot find EEPROM and Wire links in the Library Dependencies. Are they unnecessary?

[@huskialn2008]

No launch configuration in eclipse,there is another way to open the code?

[@sanosanbaby]

I haven't found UV LED strips with s/m 360nm.. so it won't be working efficiently. all the strips I've found around the Ali has s/m 395-405nm only. Please let me know if you find the ones.

[@kasparsbogdanovs7684]

Don't worry too much. I got good quality leds with 395nm wavelength. Not yet made a board, but tested on UV film and they work very well.

[@user-wk6gr1cs3o]

Excellent on this project. Please send the project code

[@TheGEMINIINTERNET]

Sir Can we use this for rubber stamp making purpose please

Σιγουρεύτηκα ότι είσαι Έλληνας από το μ.μ. στην ώρα του υπολογιστή! Φιλάρα τα σπας, άψογο βίντεο! Μια ερώτηση μόνο. Γιατί συνδέεις σε σειρά τις LED; δεν θα ήταν καλύτερη η παράλληλη σύνδεση σε περίπτωση βλάβης μιας ledοταινίας;

[@lytrax9735]

Γεια σου φίλε, σ’ ευχαριστώ. Ναι, Έλληνας, το έχω βάλει και στο forum της κοινότητας στο hlektronika.gr εδώ www.hlektronika.gr/forum/showthread.php?t=90993. Δεν το σκεφτικά αυτό που λες για την λεντοταινία, αλλά έχω την εντύπωση χωρίς να το έχω δοκιμάσει, ότι η συγκεκριμένη λεντοταινία συνεχίζει να δουλεύει και αφού καεί κάποιο LED. Νομίζω πως έχουν κάποιου είδους παράλληλη συνδεσμολογία τα συγκεκριμένα LED, αλλά αν δεν ισχύει αυτό, τότε έχεις δίκιο, θα έπρεπε να τα συνδέσω παράλληλα.

[@leonardomedina5934]

Why we have to cut the strips?? Why just dont use them as they comes?? Less work, not soldering. Could it work??

[@christopherwilliams1112]

Hi! Can you tell me what model scanner you built your unit in? This is to give me an idea what model I need! Chris Williams

[@lytrax9735]

This is a HP Scanjet 2400. You can do it with any scanner box; it's an easy way to get a box that has a glass surface and closes.

[@christopherwilliams1112]

@@lytrax9735 Thanks for that - An EEV Forum Member also said the 2410 was the same apart from colour! I was after that or one very similar as it has the buttons conveniently placed on top and power/USB sockets already mounted on the back! Regards, Chris Williams

[@user-wk6gr1cs3o]

Where is the programming code?

[@CharithHansakaGoonathilaka]

what is the software that you have used to drow the diagram ?

[@christoslytras7912]

It's Microsoft Visio.

[@xpavlicek]

Hi, what is the exposure time with these LEDs? Thanks.

[@lytrax9735]

Hi. I haven't tested it yet, but I hope I will do some testing soon and see the exact exposure time, but I suppose it's between 80 and 130 seconds. I will cut some small PCB pieces and test them to different exposure times so to end up with the best exposure time result. I'll reply to you when I'll do it and I hope to make a video while doing the tests.

[@HentaiNat]

Why didn't you defuse the light?

[@Nattapol221]

ประโยช์ของมันคือ?

[@klebsartstudios]

ok.....um ....why? why do i keep seeing these things made this way? wire up the led strips to a wall transformer power supply, plug it in to turn on the lights, and set a ONE DOLLAR egg timer from walmart to time your exposure! ....then unplug when the time is up...why the whole "built in'" timer circuit, complicated logic, etc?

[@lytrax9735]

If you don't like DIY videos, then you should go watch sometinh else... You think everything in this world is "simple"? All the devices you use everyday do have VERY complicated logic.

[@MrTonmit]

Why does one climb the mountain? Because it is there.

[@stustjohn]

Why? Because it's interesting, neat and fun! My only (big) concern is that glass absorbs UV, so I'm wondering how effective it actually is...

[@mvssarma3387]

I request for a latest version of firmware or a workable .he's . After pooling all the includes tried to compile. I get an error line undefined high_btightlight. Please try to accommodate Thanks Sarma Vu3zmv

[@wilwahabri]

Which version of the IDE did you use, whenever I compile with Arduino IDE v1.8.19, I get error messages which do not stop the compiling however when powered up the displays do not light at all C:\Users\wilwa\Documents\Arduino\CL_UVScanner\Program.cpp: In member function 'void Program::initialize()': C:\Users\wilwa\Documents\Arduino\CL_UVScanner\Program.cpp:39:24: warning: invalid conversion from 'void (*)(Program*)' to 'CL_Button::doevents_callback {aka void (*)(void*)}' [-fpermissive] m_startBtn.onDoEvents(&this->run_btnDoEvents, (void*)this); ^~~~~~~~~~~~~~~~~~~~~~ In file included from C:\Users\wilwa\Documents\Arduino\CL_UVScanner\Program.h:17:0, from C:\Users\wilwa\Documents\Arduino\CL_UVScanner\Program.cpp:14: C:\Users\wilwa\Documents\Arduino\libraries\CL_Button-master/CL_Button.h:25:7: note: initializing argument 1 of 'void CL_Button::onDoEvents(CL_Button::doevents_callback, void*)' void onDoEvents(doevents_callback doEventsCB, void* arg); Appreciate your comment
