7.5" Price Tag Telink TLSR OpenEPaperLink Flashing How-To

[@timkoehler3669]

In future we’re not shoplifting for the goods sold in the store, but for the pricetags they’re using :)

[@RickRolling-tc7vb]

Excellent! Thanks for sharing this, unveiling the mysteries of the epaper yet again. Keep up the good work.

Where can these Nebula tags be purchased?

[@DaveBrown1]

Good question.

[@TheChillieboo]

this is a really good tutorial! thanks man!

[@H0mework]

If you have a lot, you might want to make a jig. Very cool!

[@Sunscreen723]

seeing this plastic melt is so satisfying

[@VoltageGoat]

Nebular-750Y-N Are there multiple kinds of displays which will take the same firmware?

[@Chaminox]

Awesome Video, Where do you get your Displays from? I tried looking online but couldn't find a good site

[@viteosen]

I have Nebular 290R-N in my hand. I've cut plastics on the back and found debug pins. But how to port OpenEP for it? lut and etc. please, share the knowledge)

[@timkoehler3669]

How long will it take for companies to notice, if we bring back the pricetags with our prices programmed :)

[@Roobotics]

It would be interesting if the 3 pads needed could be targeted with a 3d printed drill jig! But the user would still need an accurate pogo setup to go along with that. Being able to seal it all back up with a strip of tape, would be very clean though. Also I've found that many USB-C irons and hotplates float the tip to 1/2 of mains because of XY capacitors inside the charger, if your circuit being soldered is grounded, that's getting shunted into each I/O pin possibly. On my MHP30 I realized it because it had a 'texture' that you could only feel when it was plugged in, DMM confirmed why! Does it on every 60W PD-Charger I've tried. Can light LED's in series that are only touching your skin and the plate.. etc. Best way I fixed it was clipping a grounded lead on the USB shield. Just be aware it's often there, and can push current into sensitive things.

Thank you ❤

How do you spell the word you used for template?

[@atc1441]

Something like: Schablone -> Template

[@DirtyPlumbus]

@atc1441 thanks. I replayed it like 4 times, trying to understand what I was hearing. I understood what you meant but couldn't quite the word down.

[@ange7v]

have one HS_EL5102_9M_51_00 from Hanshow, its any firmware compatible with this model?

[@ntfshard]

just find couple of pads to add physical buttons and it can be converted to a some text reader.... or run doom

[@maicod]

Nice Firmware Hack

[@sebakiller9736]

😂Great Plastic smalting Plan to Flash new Firmware 😅

[@JohnHawkGermany]

I have flashed several Hanshow Nebular-350Y-N using your FW TLSR_HS_BWY_35_ALPHA.bin successfully. Is it possible, to use one of them as an AP? If not, I have laying around a Lilygo T-Display including an esp32-S3. It costs about 10$ on AliExpress. Could that be an alternative for building an AP?

[@DaveBrown1]

Hi John, sorry I dont know about the API. I am struggling to get the Tag to flash. Have a 350R-N & I see you have the yellow version working. I open the port and unlock (blue led ok) and select FW TLSR_HS_BWY_35_ALPHA.bin. When I flash I can see the TX Led on the converter flashing with the blue LED on the tag. However the tag does not re-boot. sceen still showing the original data. Put it on other USB ports changed USB lead and attempted other versions of firmware. ANY idea John? or anyone else having the same probs. Regards Dave

[@JohnHawkGermany]

Hi Dave, did you shortcut the Battery Connectors after flashing to initiate the reboot? Did you try it on more than one ESL? Always the same result? Batteries still good, or tried Workbench Powersupply? Maybe the firmware for the red ones is different? @Aaron Christophel can you confirm?

[@atc1441]

Red is not supported

[@DaveBrown1]

@@JohnHawkGermany Hi John & thanks for the reply. Good point about the reboot and the battery, I will check the battery voltage and give it a quick short and check for a re-boot. Only have the one ESL. I did see R(red) in the firmware link so not sure if it is supported. If any progress I will update the thread. Thanks

[@atc1441]

Hey Red is not supported right because of the lack of it to adapt the firmware
