The bendy straw LED light defused is a brilliant application of 2 bits of scrap material, the straws, and the non-working flash light. A brilliant solution! In fact, the whole project is in the genius category, IMHO!
Great little project! Here's a tip that can significantly increase the amount of light behind the slide: Simply place a piece of tinfoil behind the tubes to reflect all the light back, that went out of the tubes in the wrong direction and would otherwise just have been absorbed into the black bottom. Make sure it also covers the sides so that light can't escape that way either. You'll be amazed how much light you can actually get out of the leds that way. Anyways thanks for sharing. Great idea!
Nice job! I might have glued (or use double stick tape) a piece of reflective paper (any foil/Mylar lined jar liner might do) on the inside facing the LED light tubes side of the base foam-board to take advantage of as much of the light as possible.
This is a good effort. I especially like your jigged foamcore construction techniques. I've built a few phone scanners. You can get a good result, especially with a good even lighting source and the Kodak app, but even the best phones (as of September 2019) struggle to get resolution at macro distances compared to a scanner or a proper camera. You will get results good enough for social media, but you won't make archival quality images or decent big prints.
scan them at high resolution with a scanner and use a colour printer to print them on a4 transparencies. :) then ... develop a really huge mobile phone... i dunno.. oO
@@parishna4882 Keep the goal in mind - if all you want to do is load up some old negs onto your cell phone to share, why make it any more complex? If you want more resolution/color control, then a proper scanner is the way to go. But there's no need to make it any more complex than it has to be.
The box is a great idea. However, cheap LEDs have very low CRI (colour rendering Index). I think using an old phone with the screen on full brightness would be simpler and gives better white light.
Brilliant! My father was a proponent of the hot glue gun and this McIver light box reminded me of him. I have a light source so will try to make the enclosure. Thank you!
Has there been an update to this great build? I see you can buy little light panels now, a way to avoid all the desolder and soldering, just wondering 😊
I build sth. similar, using the cheapest flat LED ceiling light I could find in the hardware store and crafting a "stand" for my DSLR from a yoghurt cup (one of the larger ones. But: the "lightstraw" idea is gold! I would have never thought of this!! Thanks man. You earned a sub with these straws. I save that idea for the next time I need a small diffuse light source. You could even add adjustable blue and yellow LEDs to (sort of) adjust light temperature.
Thank you for the video tutorial very well presented you explained everything so clearly. I really enjoyed watching , well done and thank you have a good weekend bye...😃
This is so good! ✨ One question though - - overtime, will the plastic bendy straw melt coz of heat from the led light? I want to know your thoughts on that. Thanks!
What about remove scratches from negatives and use infrared scratch correction? also it hve very bad dynamic light range and not work for hi quality sources. I use drum laser scanner. or restoration negatives in ultrasonic bath, and after scan negatives in liquid use some adapter for Nikon Scanner.
I'm wondering if this technique would be feasible to use in converting old 8 mm movie film into digital files which could then be restored using photoshop or whatever?
@@MrRubyxp That is also what I was refering to, but it seems that it is just a paperclip or something. You can also use solder for this application though.
Regarding the lighting source, I bought a domestic LED panel light with a really well diffused light. I wouldn't want to use mains voltage in any project unless you're qualified, but I learned a lot about how it was diffused. Instead of shining straight through the diffuser, the LEDs shine into the edge of a clear panel. There is a reflective sheet behind the clear panel, then a white diffuser as you used, followed by a sheet of frosted clear plastic to spread the light. This last layer isn't needed for your kind of project.
You might want to think on designing the whole thing around the camera position, that way you could bring your phone and expect it not to wobble. Also, you can review the camera's focus distance. That's the minimum distance that the camera needs to be to take a focused shot, and that should save you the focus measurement. Overall great video and I might go ahead and do it on my end. Thanks for sharing!
Straight from the "why the heck didn't I think of this" file...I've got a stack of 6x4.5 negs (and some positive films as well) sitting around that I'd really like to digitize but really can't justify the expense. I can so justify the expense of some foam board and translucent Plexi though!!
Or just simply place the film on a tablet which is displaying a white screen. Slightly more practical and helluva lot easier. Still, I admire your work. Liked and subbed
A very informative tutorial... youve inspired me to build one out of 1/4 inch MDF and tweak your rendition to accommodate my specifications I will now sub just because you've intrigued me Thx!
I made a similar one using an old photo paper box (black inside) and I use an iPad as a light source. For an even better result: place your negative or dia under a piece of glass.
🤣 I love the idea,but the foot safety part felt like this was gonna turn into another kind of video. Thanks for the info. I’m gonna build one for 120 film.
If you were to use a rechargeable battery, i think you would be better off making a less permanent solution to hold the battery (ie a casing instead of glue), though I’m sure you wouldn’t need to replace/recharge it often anyway, the LEDs being very energy efficient
Yeah, nah. Colour negative films are more complicated than you may think. That orange base tone is a correction mask produced in the image during development, and it varies in density according to the colours of the original image. Also, different manufacturer’s film have different orange tints. For accuracy you need software that’s sophisticated enough to both detect the film brand, and to apply compensating filtration according to gamma (the degree of contrast according to exposure) for each masking layer in the original film. If you don’t have the right software, getting acceptable colour can take a lot of fiddling around with Photoshop or Gimp.
I think you should add more lighted straws. At the end of the video, I can clearly see very dim dark bars between the lighted straws. Excellent project nevertheless.
My grandma died and i have her film negative collection and im bad at building stuff lol i was wondering if you could build me one and I'd definitely buy it

the foot part was unexpected.
It's an asian thing 😂
@@TechBuilder seems a bit dangerous! :)
lol its normal for asian ppl
Safety first!

Great idea and great video. Other alternatives are much more expensive.
But the bare foot beside the saw was a bit shocking.

Great idea!
I'll have to adapt this idea to work with my personal View-Master reels, thanks!
This is awesome. But I can’t do all that. You should consider building and selling these. I’d buy one
Great video ...can you please advise what negative storage box do you have?
This definitely needs a kickstarter campaign.
You're absolutely right.
This is fantastic! I'd recommend not putting your thumb in the middle of the negative, the oils in your skin can leave a mark.
In the worst case mildew will grow there and destroy the layers
Cotton gloves are the way to go & they're super cheap on eBay.
Amazing! When he starts to cut the light diffuser, he whips out the clamp that looks like a foot!

This is a much better idea using bendy straws, spare leds and foam materials. Very much like it.

I'm probably Gona try build something similar to use with my actual mirrorless camera and then convert it in lightroom. This is pretty cool project
If you don’t have a diffuser, buy one!!
That’s really helpful thanks!
For such seriously prepared, good tutorial video, I wish you to have millions of subscribers!
I CONCUR; THIS IS AN EXCELLANTLY PREPARED AND PRESENTED TUTORIAL. KUDOS TO YOU , TECHBUILDER. A GREAT JOB
Thank you for the video tutorial very well presented you explained everything so clearly. I really enjoyed watching , well done and thank you have a good weekend bye...😃
Awesome project, just what I've been looking for! Can't find the pdf link for the project though 🤔
Great DIY project; here's another thumbs up in words!
That was a great video… I will probably make one soon. I have boxes of negatives that need printing!
Thanks… all the best man.
Where’s the link for the light box?
Wow, this young inventor has grown. Puberty period.
What kind of foam i can use? I can use also black painted wood?(from the factory)
This is so good! ✨ One question though - - overtime, will the plastic bendy straw melt coz of heat from the led light? I want to know your thoughts on that. Thanks!
LEDs have little to no heat waste so it should be all good :)
@@PieFlavouredPii Noted. Thank you, Sam! :D

Can a person buy a premade one?
Which phone you used in this project bro.. please tell me
I'm wondering if this technique would be feasible to use in converting old 8 mm movie film into digital files which could then be restored using photoshop or whatever?
Awesome!
Please make a tutorial about 18650 battery pack 👏
Elegant, simple. cheap and functional. Nice work!
“its like a lightsaber” OMG I LOVE U 💜
Like it...you explained it so clearly. It's fun though.
Thank you!
how i can make a wall proyector for 35mm? or maybe make more large view?
Isn't it important to choose high CRI light source?
It is
where you bought the book to keep those photo negatives?
I love the bendy straw lights sir, it's more of the incandescent bulbs like you said.
Thanks for sharing
Welcome! Thanks too!
Would it be safer to use your left foot. Clever project. Thanks for posting
Are those led's 3mm or 5mm?
Please tell me you didn't have open toes next to a moving saw?
May I know what’s the metal bar looking item that you use to solder the leds together @ 6:44 ?
It’s just solder
ー。ー두부 I’m not referring to the solder fusing the led. I’m talking about bar connecting the components
@@MrRubyxp That is also what I was refering to, but it seems that it is just a paperclip or something. You can also use solder for this application though.
The best way to cut plexiglass is to scribe it with a sharp object, then snap it. Makes a cleaner edge than a hacksaw.
Astig ka talaga! ❤️

I think I might just have to give this a try. It'd be Great to have those old slides taken at LeMans converted to photos I can share.
so satisfying to watch! cute nerdy guy, too! :-) :-) :-)
Eu já imaginava como fazer, e você com o seu vídeo so reforçou a minha idéia.
Obrigado!

Can you make film projector too
You are so creative and innovative and practical! Thank you for this. I will adapt your ideas for use with my mirror less camera.
I know ow to make a box but I don't know how to convert form negative to positive pictures.
😮
Fantastic idea, dude! Really well done!!!
Excellent instructions!
Lovely! Are those your parents visiting New York city? Thanks for your video
So you got a power supply but not some claps to hold that acrylic down?
Very innovative solution!

I see your foot to stop in place the plastic and I press "Like" immediatly 😁
Feet > Vice :)))

when I use my phone, I always get a reflection of the phone camera on the film itself. is there a way to get around this?

Where can I find the link for the foam board blue prints?
How many millimeters thick acrylic board?
How do you know which one is anode or cathode?
The carhode has a flat edge, you can also identify the carhode by looking at the metal inside thr LED. The cathode has the thicker one.
TechBuilder Thanks!
I want to try evething the only problem is I don't have the materials
buy them
Why do you put glue on the battery? How do you get it out when the battery is finished?
DLH Fordada hot glue is really quite easy to rip off
@@-lll-ll-llll-AVE Thanks for that info. But would it be easier to use a rechargeable?
If you were to use a rechargeable battery, i think you would be better off making a less permanent solution to hold the battery (ie a casing instead of glue), though I’m sure you wouldn’t need to replace/recharge it often anyway, the LEDs being very energy efficient
Clever and useful. The key of inventive,
3:07 Very important. Be sure to not wear any shoes when using a saw so close to your foot.
YEAH! FUCK TOES!
I am floored by this!! definitely going to try this
Génial! Je vais essayer tout de suite! Bravo! Félicitations!
Genius work!
this film scanner is great. but i think it will be better to invert negatives in regular pc program like gimp or if you have money in lightroom

That orange base tone is a correction mask produced in the image during development, and it varies in density according to the colours of the original image.

I think you should add more lighted straws. At the end of the video, I can clearly see very dim dark bars between the lighted straws. Excellent project nevertheless.
fantastic video very easy to make but it is not great prastic to have a hack saw at your bear feet when cutting any materials.
3:12 Nice Clamp, whatever works I guess, huh? good video btw!
How do you know which is the positive and negative on the used led? New ones have one of the contacts longer than the other.
LEDs have a flattened edge, the pin closest to that flattened edge is the Cathode (negative).
@@TechBuilder Ah awesome. That I didn't know. 😉
How cool is that! Really fun to watch! Are you selling this? 😉😁
show de bola! greetings from Brazil!
Bro, can i have the pdf link? For building the enclosure
Loved your idea.
I just got a roll of film back I didn't get scanned cause getting so many rolls developed was getting taxing so this is perfect!
The colors on the inverted images looks wierd, maybe the white balance ia wrong?
I guess so. Nothing a photo editing app can fix.
What is the app?
Nice one bro!! 💯 I like how you recycled some materials! 😁
Thanks Cal!!!
