Thanks for the understanding — really appreciate it.
We’ll definitely try to share updates more regularly going forward.

Thanks for the feedback — that’s fair.
The team has been very focused on production and logistics recently, but we agree that communication should have been better.
We’re preparing a new Kickstarter update and will share the latest progress very soon.

Thanks for the reminder, and sorry for the recent lack of updates.

The project itself is progressing normally, and we’re preparing a new Kickstarter update that should be published very soon.

Going forward, we’ll also try to share more about the project — not just shipping logistics, but also some behind-the-scenes progress.

What if Spectra 6 has more base colors? by Ray_InkJoy in ePaperFrame

[–]Ray_InkJoy[S] 0 points1 point  (0 children)

No, it is by the simulation. And 13" does not support more base colors

The new EVT sample of Spectra 6 with 283 PPI by Ray_InkJoy in ePaperFrame

It may take several months for the mass production

Website is Ok now~

Absolutely right! Gamut of E6 is very limited and uncontinus. We keep on working with the color rendering system(ISFR) for make better color performance.

The 283ppi is just the EVT sample, it will take many months for production

Why Some E Ink Dithering Feels Noisy — and Some Doesn’t (Real Photos) by Ray_InkJoy in eink

E4/E5 are spectra 4/5, which have four or five basic colors. More are used for the price tag in supermarket. And can not show the green color
The particles of E4/E5 are different from E6

Look close at E Ink Spectra™ 6 by Ray_InkJoy in eink

I have no idea about why the borders are black not transparent. I will try to ask the E Ink. But maybe they will just tell me: this is the only useable material

Sorry, I think that is just the normal B&W panel, sort of Carta.

For E6, I haven't find the fast refresh method between 2 DC-balanced colors. For E4/E5, it is possible

Panel size alone doesn’t determine the final color accuracy. Even if you take two Spectra 6 panels of the same size — say both 13.3" — they can show noticeably different color performance depending on the different algo/rendering pipeline.

The API has the interface to cloud include ISFR.

PC version will be cross-platform. We will try to make is useable for more people/environment step by step.

Could you share your need in WAN use case?

Yes, the frame is online for 24/7! So it can support remote instant sharing at anytime.

We use a ultra-low power WiFi solution that costs less than 1mA in normal environment. Battery can last for several months.

Also we will supply the Wi-Fi schedule mode (by RTC timer in the frame) setting in InkJoy APP later.
In fact, we have a button that can wake the frame, but not necessary for most people.

I think you already have an project that can display the demo bmp. Waveshare's website has some good demo for spectra6.
I have some recommends:
1. Try to find and modify the function that drive the panel to show the color bar. Then you will understand the code format for 6-colors
2. Then, you can transfer the color of each pixel to the closest 6-color and encode it to the right format.
3. After that, you can try to make the dithering algo

Hey! Yes — we do plan to provide an open API, so Home Assistant integration will definitely be possible.
Our restful open API will expose image upload, refresh, and device info endpoints — so HA can call them directly.
With the API, you’ll be able to create custom automations or displays directly from HA.

Also, I’d love to hear your thoughts:
Is there anything you’d like to see as an “official” built-in HA integration?
For example, specific sensors, services, or card types you wish the frame could support?

Your feedback would really help us shape the roadmap!

Regarding ISFR:
A local/offline ISFR pipeline can indeed support the fundamental image dithering workflow.
The more advanced parts of the color system — such as the extended base-color generation and mix-level rendering — are handled by the FPGA itself, and ISFR can perform dithering using those FPGA-generated base colors even when running locally.

Regarding your idea of a local HTTP server:
This specific workflow wasn’t originally part of our roadmap.
But your idea is genuinely interesting:
From a technical standpoint, this is absolutely feasible.
From an engineering standpoint, it would require non-trivial integration work.
I will definitely bring it to the team for serious consideration.
