Make a UV PCB Exposure Box Using an Old Scanner 

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

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 :-)

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!

Nice job.

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 !

Perfect

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?

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

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

My UV exposure made same way :)

Many thanks please

What’s the wavelength of your led strip?

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

Good

Sir Can we use this for rubber stamp making purpose please

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

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

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

Can we use UV & white lamp together to scan documents

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

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

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

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.

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;

Excellent on this project. Please send the project code

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

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...

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?

Where is the programming code?

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

Why didn't you defuse the light?

ประโยช์ของมันคือ?

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?

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

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
