A full colour e-paper photo frame would be great.

No need for power cables or constantly recharge a battery.


Stanley--Nickels t1_j8s40o7 wrote

I think an actual photo would do that job a lot better. Until color e-ink comes a looong way.

I think colored e ink is good enough rn to be honest. It looks like slightly faded newsprint which I’m plenty pleased with


Stanley--Nickels t1_j8tv5an wrote

I've only seen it in videos, so I'll take your word for it. It seemed pretty dull without either a lot of light on it or some kind of front light.


CinnamonSniffer t1_j8x0ebi wrote

Yeah I don’t buy ereaders without front lights anymore. Even in direct sun it makes a big difference

Just get a digital photo frame, what’s the point of this?

It's just someone's fun personal project... This isn't something going to market, someone just had an idea and wanted to document their process to completion meanwhile sharing all of the resources in case someone else wanted to make one of their own.

It’s a tech demonstration if nothing else. E-ink badly needs to renewed interest. It’s difficult technology to work with - but I long for a future where they are commonplace in screens. They’re awesome.


Kosco97 t1_j8urgci wrote

I don't think they're gonna get interest outside of niche commercial applications

Full color is coming out. It will be a game changer when price comes down.

Everything that doesn't need video will move to eink because it is so much lower power and better daylight readability than LCD.


Redeem123 t1_j8t3opi wrote

They literally just said - no need to worry about battery.

Might not be a great use case for everyone, but I feel like the comment was pretty clear what the point was.


Kosco97 t1_j8t4enh wrote

Print the photo, it'll look infinitely better than this and last longer


Redeem123 t1_j8t8sup wrote

Sure, I don't disagree. It's what I would do too.

But if your goal is a screen that could change pictures when you want at no additional cost, that's something that a printed photo can't do.

That is how innovation starts. Unless you’re getting secret alien blueprints from the centre of the hollow earth.

It's the high tech equivalent of a DiWhy. I love eink but this project makes no sense outside of it being art.

How do you invidious a future beyond dslr? What do those experiments look like? The creative process should be appreciated for more than “did you give me something I didn’t have”


shouldbebabysitting t1_j8y6ngt wrote

The problem is that it displays a digital photo that neither has the output quality of an lcd or oled, nor the physical permanence of a physical photo like a Polaroid. If the eink plugged in like film so the "print" could be handed out like a Polaroid, it would be more interesting.

DSLR, being a particular technology for autofocus, is entirely beside the point.


largephilly t1_j8z2t6d wrote

If we suddenly didn’t have access to the supply chain we do now. DSLR cameras would not be possible at scale. So what alternatives do we have once parts run out and prices skyrocket? This, to me, is an exploration of that question.


Bryceybryce t1_j8zj64z wrote

Bruh there’s like 15 bajilion used film SLRs and range finders + mirrorless cameras + point and shoots + digital range finders. Literally could do anything else besides a dslr and take better photos than this stupid solution for a problem that doesn’t exist. If people want analog experiences they should use analog technology. Using digital to replicate analog (poorly) is a waste of time imo. It would be interesting as an interactive art exhibit. As a product it’s e-waste

> DSLR cameras would not be possible at scale.

I don't think you understand what DLSR means. DLSR stands for digital single lens reflex camera. Before in sensor phase detection was possible, or laser range finders were possible, a separate sensor chip was used for focus. For this separate chip to work with the actual imaging sensor, a prism was mechanically raised into the path of the image to allow for autofocus, then quickly moved away at the moment of capture.

DSLR is a mechanical kludge to work around technical limitations of the time. It is more complex and requires more parts than modern cameras. If there was a supply chain problem, DSLR's would be harder to make than modern cameras. My main camera is a DSLR. But it is obsolete.

The Paperoid uses a ESP32 cam board that has a fixed focus lens. It is not a DSLR. Pretty much any cheap sensor is better quality than the ESP32 cam. Raspberry PI has a new autofocus sensor that's far better. The method of focus is irrelevant to the imaging (sensor) and storage/display (lcd or epaper) of photos.


largephilly t1_j9130qd wrote

If you don’t know what I’m trying to say you can just ask for clarification. When people bring up a Dslr camera they generally aren’t talking about literal DSLR just the fucking era in cameras. Jesus you egos are impossible to talk too. Fckn photographers man.


shouldbebabysitting t1_j915eb5 wrote

I already explained it earlier and you continued with your nonsense.

Referring to the "era" is still nonsense as I already explained that there are plenty of better sensors. Your "what if" about "supply chain" doesn't make any sense. When the supply chain dried up last year, hobbiest components became impossible to get. $35 Pi's were selling for $150.


largephilly t1_j917ibo wrote

Which would mean we would need to envision something new. You gotta make things that no one else is making and deal with good little people who can’t see beyond what’s already possible.

>Which would mean we would need to envision something new.

???? How do you go from I can't get bad sensors when there is a supply chain problem to, "I need to make a camera with a bad sensor."

Again, it's cool as an art idea.


largephilly t1_j91f737 wrote

Shall we go over the differences between “bad” and “new”? I know u get hot for some semantics bb.

If we suddenly didn't have access to the supply chain as we do now, his camera wouldn't be possible but higher quality cameras would be. As I already explained, hobbiest parts are last in line.

I don't think you read the article or if you did you don't understand any of it. The "new" part wasn't using an esp32cam. There have been thousands of people making esp32 cameras before this person. Tens of thousands of others have purchased Pi cam modules.

The new part was using ePaper instead of an lcd.

As the creator said, his ePaper camera is an interesting concept where you can take a single permanent photo. When you take another photo, your previous photo is lost forever.

The camera part, that you've been obsessed about, is completely irrelevant.


QuerulousPanda t1_j8u979q wrote

Looks like a really fun diy project, however it's kind of weird that the screen is powered by nfc despite the entire thing being mounted in one unit. I get that it's an amalgamation of parts and modules, but it still seems odd!

Anybody that has used e-paper knows it’s terrible. Very gimmicky. I had a canon IVY instant printer and it was bad.

Polaroid style is better.

Edit: oops haven’t had my coffee yet. E-paper is like a kindle? My thoughts on the image quality are the same. Probably not the best and gimmicky. But hey, if that’s what you like go for it.


LazaroFilm t1_j8sj4rv wrote

Anybody using a kindle paper white would tell you e-paper has come a long way. It’s still not perfect, but that’s part of the charm of this project, making an imperfect “analog” image out of a digital object that is also DIY. Ivy is tant printer has nothing to do with this project.
