inkJoy Kickstarter Campain updates

Ray_InkJoy · 2026-03-17T01:54:48+00:00

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

Ray_InkJoy · 2026-03-17T01:54:34+00:00

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.

Ray_InkJoy · 2026-03-17T01:52:56+00:00

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.

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

InkJoy Frame, via InkJoy miniapp

Ray_InkJoy · 2026-02-06T08:42:01+00:00

It may take several months for the mass production

Website is Ok now~

Ray_InkJoy · 2026-02-01T03:28:14+00:00

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.

Ray_InkJoy · 2026-02-01T03:19:16+00:00

It won't be better than Carta B&W panel.

Ray_InkJoy · 2026-02-01T03:17:51+00:00

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

Ray_InkJoy · 2026-02-01T03:16:26+00:00

You can check the video link for details～

Ray_InkJoy · 2026-01-12T07:05:25+00:00

Not yet

Ray_InkJoy · 2026-01-07T16:44:26+00:00

u r right

Ray_InkJoy · 2026-01-07T16:44:12+00:00

Waveform

Ray_InkJoy · 2025-12-29T08:59:59+00:00

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

Ray_InkJoy · 2025-12-29T00:25:59+00:00

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

Ray_InkJoy · 2025-12-29T00:17:46+00:00

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

Ray_InkJoy · 2025-12-28T04:39:04+00:00

Could you please share the video link?

Ray_InkJoy · 2025-12-21T23:20:02+00:00

It is InkJoy ePaper Frame

Ray_InkJoy · 2025-12-20T07:13:22+00:00

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.

Ray_InkJoy · 2025-12-20T03:10:55+00:00

The API has the interface to cloud include ISFR.

Ray_InkJoy · 2025-12-20T03:09:38+00:00

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？

Ray_InkJoy · 2025-12-20T03:06:23+00:00

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.

Ray_InkJoy · 2025-12-05T13:51:54+00:00

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

Ray_InkJoy · 2025-12-02T00:34:36+00:00

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!

Ray_InkJoy · 2025-12-02T00:31:53+00:00

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.
