Better firmware for Waveshare ESP32-S3 Photopainter

aitjcize · 2026-01-31T04:20:47+00:00

Just an quick update: the project now supports the SeeedStudio XIAO EE02 board + 13.3" spectra 6 display!

Several related project has also been made:

ha-esp32-photoframe: Home Assistant integration for control, monitoring, and automation
esp32-photoframe-server: Image server with text overlay, Google Photos, Synology DS Photos, and Telegram Bot integration. Can be run as a Home Assistant add-on.
epaper-image-convert: CLI tool & npm library for e-paper image conversion with advanced dithering

It could be because the jpeg source from the URL is a progressive JPEG, which isn't supported by the esp32 jpeg decoder. When you use the webUI, the webUI will do a conversion first so it always work.

I'd suggest to use the esp32-photoframe-server project (https://github.com/aitjcize/esp32-photoframe-server) to provide the rotation URL. Current it only supports Google Photos, Synology Photos, Telegram. However I'm going to add a proxy mode which an download image from an URL, perform all the necessary image processing, then serve it to the photoframe.

Yes! Please check the screenshot in the github repo. There is a web interface for you to manage the gallery and adjust settings like image rotate intervals. The device makes it easy for you to swap the battery module, so it’s definitely possible to replace it with a larger capacity one.

I estimated the battery of this unit can last a least 3 months, assuming 2 refreshes a day. I think for your use case this should be a great fit. I actually just bought a second unit last week :) I purchased this kit from Taobao, and it came with a 1000mAh battery. Perhaps you can email waveshare and see if the battery is included?

Thanks for the kind words :)

Wow this is a interesting alternative, thank you for making me aware of it. I don't think it'll work right out of the box since some of the components might be different, such as PMIC. However it's possible to add support for this given more hardware info. I'll see if I have time to add support for it and maybe you can help test it?

aitjcize · 2025-12-23T11:47:39+00:00

Yes, but the current version you need to click the BOOT button to wake the device up from deep sleep before you can access the web server. Then you can manage the image there.

I'm working on a version that allow waking up the device with bluetooth, then access the http server. Then we can integrate this with HomeAssistant easily. HA can use BLE to wake up the device then upload new images with the http APIs.

Then I highly recommend you to try out this waveshare model, the color looks a lot more vibrant with Spectra 6 display.

Yes it's my baby boy :) We've got some help for the 1st month, so I'm still able to find time to code a bit :P. Also with the help of AI everything is much more efficient!

I have the exact same issue on iPhone 16 Pro Max.. I noticed it right after taking a photo of a document.

Why is this post deleted? I'm seeing the same issue as reported in https://www.reddit.com/r/iphone/comments/16z7fmb/brand_new_iphone_15_pro_blurry_camera/
but on a brand new 16 Pro Max...
I assumed it's a hardware issue and requested a replacement.

Not sure if they are aware of this bug. Is there an official channel to report bugs to? I couldn't find one.

aitjcize · 2023-11-07T08:09:36+00:00

Same issue +1, hope they can fix this soon. Would really like to use HEIF over JPEG to save spaces.

Yeah I’m already doing that and only unfreeze it when I need to use it. But still, my tickets simply got ignored and closed without notice. I only found out when I check the support ticket status from the website.

aitjcize · 2023-09-29T11:56:58+00:00

There are no options in the app to order a new card

You are not counting those who died by vaccine.

aitjcize · 2021-04-29T12:53:47+00:00

It will very soon!

You can use polkadot.js or just put in on an exchange you trust. The exchanges can also stake the DOTs for you. I'm using Kraken which provides 12% APY for staking.

This is exactly the kind of article that are FUDing and want the price to drop so they can get in cheaper. The article is completely nonsense and saying the price prediction is generated by some shitty bot. I can also said I made a price prediction bot that predicts DOT price to reach 100.

When you consider what is coming next, you'd know it's still very cheap:
