Recently I realized my local grocery store replaced traditional price tags with electronic e-ink (epaper) price tags / shelf labels. I found out that you can easily buy the same ones from e-bay, and I was able to re-program / hack them.
These devices can be used as cheap Arduino E-Ink Displays, and you can easily program these with usb-TTL adapter, or any Arduino board.
The brand of the e-paper display I re-program is Hanshow, and the model is Stellar.

I am working at a company that installs and programms these tags. They are normally updated via a special access point which is connected to a local server in the market. For big market chains they are getting their prices from a central server somewhere in the world. For smaller markets they can enter the prices manually in a special software.

@devinholland2189 Год назад

I there a way to program a single one using a device you hold near to it? NFC or RFID style interface?

@CallousCoder Год назад

@@devinholland2189t shouldn’t be too hard to make this yourself. These are off the shell price tags. So if you buy one you’ll get access to the api for sure. And seeing this it’s just a simple http session that you can sniff and use Yourself. And the contents is just an image. So it’s just a post of a base64 encoded image.

@karlfrankeser Год назад

Acutally these tags are super encrypted! I once talked with the local installer of the Imagotag brand and it is super secure. Once you setup the tag in a network it is set for life on it, only a special encryption key can be used to reset the tag...

@someguy4915 Год назад

@@karlfrankeser Oh wow 'super encrypted', is that like military-grade or even better? They're set up in the network and then are set up for life? Wow, so even if the network goes down they are still in the network, that's really super-network. Basically the same as practically any wireless network, such as Wifi, where you setup the access method (WPA2-PSK for example) and then it will be able to connect indefinitely... Sorry to burst the bubble, but the guy taking these out of the box and registering them as he hangs them on the shelves is not an engineer and usually has no clue how they work, just how he is supposed to set them up... Same as how a taxi driver is usually not aware of the exact design details of the engine in his car...

BestBuy has had these for a while now, but as far as I can tell they work with IR, like a TV remote. We just scan the barcode for the tag at the register, then enter in the product we want to link to the tag, then the tag updates automatically. There are these large chrome saucer looking things hanging from the ceiling all around the store, and if you point a camera at them while setting a tag you can see a ton of IR LEDs blinking.

That makes a lot of sense, it's a big investment but over time it pays off.

@@TheFPSPower they are pretty handy. They update automatically so we don't have to go around changing labels when the price changes. Ours also have an LED so when we can't find where an item is supposed to be we can make the tag linked to that item flash a green LED. I'm sure the labor saved alone makes it worth the investment.

They have these in a large department store here in Canada. They use the built-in LED to more easily find products in some cases. For example, when buying a light bulb for your car, you can look up the model you need on a touch screen (by entered your car brand, model, year etc) and then there's a button that says something like "flash price tag". When you press it, the LED on the price tag for the bulb you selected starts flashing bright green, which makes it really easy to spot it among the hundreds of other similar looking bulbs.

If you want to program 50 of them without soldering, I made a tool that would work a couple months ago. There was a similar physical interface on a GMRS radio that I was trying to troubleshoot. I measured the hole pattern and drilled a 1/4" piece of plastic. I then used pieces rigid wire connected to a mini-grabber. Gravity held the rigid wire down to the connectors well enough to program it. In this case if the plastic adapter is cut(or 3d printed) to the size of the opening of that case then it will line up the pins for you.

@@Ale_giro Usually, if they have the same brand, only specs are changing, and you can still re-program those. for example some of them have smaller screens, so you need to send of course smaller images to them. some of them have cold resistant, apart from that they can use same firmware.

I was apart of a Best Buy remodel team that put these up, they're so cool! I had asked a lot of questions about them. One being if they could update automatically (like in a price change) and the answer was yes! There are transmitters in the ceiling that can send information to individual tags, even when they're close together.(I've even had them go off my mistake in the box or in my hand probably due to the same id?) Unfortunately I get the chance to have a the PDA to program them myself but basically it's scan that barcode on the tag then the product, wait a bit then it starts strobing! My guess is, the PDA sends this info to a centralize computer that then sends the programing data to the tags through those transmitters via IR. That little blip from the tag after programing probably means 'complete'. They had them in this size and a *much* larger size too, for the appliances, I think something like 2½"x3" maybe? Those for sure can be used in projects and would be cheap!

@makersfunduck Год назад

In the next video, I tried to do something similar (#17) for personal practical purposes. It uses the Bluetooth on your PC and your PC acts as a transmitter. and you can get a regular updates from any website.

A German supermarket chain I shop at here (UK) has recently rolled those tags out to our local stores, and the larger size is about 4" x 6". Likely intended for bigger ticket items, but they've been deployed mostly throughout their "Middle of Lidl" section. (Discounted non-food items).

I know in Albert Heijn employees can log in on those handheld terminals (ZEBRA android devices with special software and barcode scanner) and log in to a software that allows you to change what product is displayed on those tags/fix them if the display isn't working correctly/refresh it. You can also find the product by activating a green LED that flashes

Batteries need to be replaced every 2-3 years depending on how often the displays are changed or how much the LED is used.

@SeekingTheLoveThatGodMeans7648 Год назад

I remember vaguely a satire article that printed in a local newspaper three or four decades ago about shelf tags like this, where the posited communications medium was a cathode ray tube or other modulated light, and each scan just raised the price, and the TV in the electronics department kept raising the prices. Obviously this was well before the formal invention of this product. It's a crying shame there isn't a better way than we have now to recycle these things. Even if they can be reused for a long time, the need for new batteries to be installed periodically would be a valid issue. Could entire shelves have low voltage power and communication outlet strips on them, obviating the need for each tag to be autonomous and hopefully rendering the whole system hack resistant? How fast can these tags update their image? Could they do a kind of crude video?

@digitalchaos1980 Год назад

Maybe use NFC for comms and wireless charging for power! 😎

@marsrover001 Год назад

Yes these tags could be made much cheaper by using wireless charging coils for power and something nfc like for data. The scanner would be unique but one scanner can change infinite tags. I don't like the battery and Bluetooth/ir system big stores now use. As it's intentionally more expensive up front so all tags can be remotely updated just to put one more employee out of work. Technology is supposed to make life easier, not put us out of work.

@renakunisaki Год назад

They can refresh at about 2FPS but for better display health you need to do a full refresh every few frames which takes about 5 seconds. So, not good for video. (I don't know if this controller supports fast refresh.)

@makersfunduck Год назад

Himm, I know they are using it to register the tags to their systems, however if they are also using it for that purpose, that is very clever.

@dh2032 Год назад

@@makersfunduck it only guess, the real that sticky labels, lumps of plastic, look very simple in construction, loop of wire and resistor or something making a wire loop, and the sticker one look even simpler in construction look like kitchen foil cut out loop shape and small blob of something, the do make dud one too mixed with real one, that look the same, so only real one will be working flashing light at the door ones? but display label tag I thing they will all be working ones, its a real circuit board so putting dud parts not going to make any since

@ghostcat8244 7 месяцев назад

I mostly see those tags at Best Buy or target. It’s the only two store chains I notice

@xtevesousa Год назад

In the conclusion there is some ghosting under the 7 of the temperature and the 5 of the time, do you have any ideia why?

@makersfunduck Год назад

It is because of the partial refresh. full refresh takes a bit of time

@bws833 Год назад

Thank you, a very interesting video. Just one question, why is there a piano playing in the background?

@makersfunduck Год назад

Many people did not like the background music, so I must do something about it in the next video I guess :/

@makersfunduck Год назад

Himm, I have never thought about that. they are using NFC to register the tags, but if they were also using it for that purpose, that is a really clever.

@MNSweet Год назад

If you don't need the high refresh rate of an LCD, the eInk is so nice for contrast at a distance. Should you choose to continue tinkering with these displays, I'm excited to follow along. I have some ideas for YT Shorts I'll reply with.

@MNSweet Год назад

YT Short ideas: - program the expiration dates of your pantry or fridge and leave it on the box or bag, so you can see if something is past due. - If you have a Pi for it: connect it to your calendar and attach it to the inside of your front door so you know if you have any events to check. Add Weekday, Month Date on top followed by # events today. - Connect one to a YT subscriber API to display the current count via a Pi - My Favorite: Put hidden messages on them and hide them in the background of future videos. Make it an Easter egg hunt for viewers.

I believe you can. I only used it to program them.

@_der_pinguin_2463 Год назад

where do you need to connect the wires on the esp, and do you need some special firmware on it?

@tissuepaper9962 Год назад

Look, if you're not familiar enough with serial communication protocols to read the labels on the PCB and know what to do, this project may be too advanced for you. Try reading about the UART, SPI, and I2C protocols and then you'll be able to answer your own question. You have to answer it yourself because the answer depends on the exact board you have and the exact price tag you buy.

@makersfunduck Год назад

it is standard serial communication. so, tx, tx, vcc and ground.

Sure. All you need is a serial communication. you can connect it to serial port of the rasp pi board, and just follow the steps.

Do not try to recharge those batteries those aren't rechargeable. They are small so they will not make huge flames but it is still not recommended.

@makersfunduck Год назад

So true

@dennis8196 Год назад

Even zinc chloride/zinc air/alkaline cells can be recharged provided it's a modified sine wave 1:5 ratio and you don't force too much back, but you can only get about 18-20 charges at 80% of the original capacity at best. Used to do this a lot during the 80's & 90's before rechargeable lithium batteries were common place.

@@dennis8196 it‘s not a good idea for CR cells and will make a horrible smell. LIR cells are supposed to be rechargeable however.

I saw one very early system that was solar powered and used the stores existing lighting to program them. I assume patents mean competitors have to use other ways.

@renakunisaki Год назад

That's a brilliant way to get rid of the literal tons of single-use batteries.

@JensGulin Год назад

@@renakunisaki agree about waste, but added components (solar cell, accumulator) and complexity probably makes it too expensive. And they will have a limited component life span anyway, or they decide to change system after a few years. End result: more money and more waste. That's the way it works currently. :⁠-⁠( Broadcasting through the flicker of lamps is quite interesting, but I would guess it would be mostly for the novelty. Radio is so well established and everywhere these days. And free to use spectrum and protocols keeps it safe.

@makersfunduck Год назад

But how do they get "sun" inside of the stores? regular lights dont produce enough energy to charge the batteries

@mfx1 Год назад

@@makersfunduck Regular lights work fine have you never used a solar calculator indoors? Eink shelf labels use very little power the solar cell just needs to trickle charge a capacitor.
