The Reinkstone R1 is a 10.1 inch tablet or eBook reader with a 2232 x 1680 pixel electronic paper display that can show 4096 colors. You can use the device to read or annotate eBooks thanks to support for an optional pressure-sensitive pen.
But thanks to 4GB of RAM, 64GB of storage, and a 1.8 GHz ARM Cortex-A55 quad-core processor, it basically has the guts of an Android tablet… and it runs an Android 11-based operating system. The makers of the Reinkstone R1 launched a Kickstarter crowdfunding campaign for the color ePaper tablet today today and it’s expected to ship to backers in November… but there are a few things you should probably know about the Reinkstone R1 before pulling out your wallet.
The first is that while the Reinkstone has an electronic paper display, it does not have an E Ink screen.
There are a growing number of eReaders on the market with color electronic paper displays thanks to E Ink’s new Kaleido display technology. The Reinkstone R1 is not one of them. Instead, this device has a 10.1 inch DES New Color ePaper display.
According to a comparison by the folks at Good eReader the display technology is a little different, and it results in more “ghosting,” or remnants of the previous image showing up on the display when you refresh the screen.
On the other hand, there are some up sides to the technology. Like E Ink’s Kaleido displays, the DES screen shows fewer pixels per inch when you’re using it to view color than black and white. But Kaleido displays show 1/3rd as many pixels per inch in color mode (so a screen that shows 300 ppi in grayscale can only show 100 ppi in color). The DES New Color display shows half as many pixels (so the Reinkstone R1’s 10.1 inch display shows 280 pixels per inch in grayscale or 140 pixels per inch in color).
The Reinkstone R1 also has a tool that lets you disable color altogether if you want to ensure that you’re getting the full 280 ppi, something you cannot easily do on devices with E Ink screens.
While the display technology is the biggest differentiating factor, there are a few other things that make the Reinkstone R1 stand out from devices with E Ink Kaleido displays like the Onyx BOOX Nova3 Color, Onyx BOOX Poke2 Color, and PocketBook InkPad Color.
The Reinkstone R1 is also more tablet-like than some competing devices. It has built-in stereo speakers and dual microphones, allowing you to use it to make voice calls, for example. And it has a 4,500 mAh battery that’s said to offer up to 3 weeks of run time.
And while the Reinkstone R1 isn’t the first E Ink device to ship with an Android-based operating system, it is one of the first I’m aware of to run Android 11.
But while that means you can sideload most Android applications, it’s worth keeping in mind that the display is a high-contrast, low-power screen illuminated by a front light. The fastest screen refresh rate you can expect is around 7 to 8 frames per second, which makes this device unsuitable for watching video or playing most games.
Other key features include a USB-C OTG port, ARM Mali-G52 graphics, and an aluminum alloy chassis that measures 236 x 167.3 x 6.8mm (9.3″ x 6.6″ x 0.3″). The R1 weighs 425 grams (15 ounces).
The optional Reinkstone stylus is an EMR pen with support for 4096 levels of pressure sensitivity and writing latency of 40ms in black and white mode or 50ms in color.
Super Early Bird pricing started at $329, but those rewards sold out quickly. A limited number of folks might be able to snag a Reinkstone R1 Early Bird special for $379 before the regular Kickstarter pricing of $429 kicks in. That’s still a 22-percent discount off the expected retail price of $549.
One more thing I should probably point out about the Reinkstone R1 – the company contacted me in April to see if I’d be interested in reviewing the device. I said I would, but then I never heard from the company again until the Kickstarter campaign launched today. While that doesn’t inspire a great deal of confidence, it does look like Good eReader got their hands on a pre-release prototype, suggesting that there’s at least one real, functional product out in the wild.
This is great.
E-paper displays are finally seeing some real application.
I see some companies are now starting to build restaurant menus, Bus Information Displays, advertisement panels, etc. 🙂
There are many more display suppliers than they were a couple of years back. A list of a few popular e-paper display suppliers is here if some are interested: https://pallavaggarwal.in/2021/06/28/e-paper-display-suppliers/
i m waiting for MIRASOL
i hate eink
Another Android device? No thx.
Put Linux on that – like Remarkable and Pocketbook (kinda) do – use the very good existing open source bibliography and reader software and we can talk.
Android is a hard pass.
as i just had a look at the “comparision” on their kickstarter…
– Having a stylus – big green mark? Who gives a fk… And it also seems to be a custom one – get additional for $$$.
– B&W ppi – worse then existing. In general imho color readers are not ready for the market to take over if they dont offer what existing b&w readers do + color. Not worse b&w reading. After all its probably still aimed for reading books.
– OS – Android (whatever Version)-> as already meantioned seeing this besides the Linux of a remarkable and Pocketbook this is imho no plus for an ereader. Support like most mobile phones? 1 Year and thats it? Meh.
– speaker -> e.g. Pocketbook has Bluetooth = use a decent speaker or headphones.
– Internal Storage -> e.g Pocketbook Color can be extended via SD -Card and your device?
– Bragging with battery life? Its compared to eink readers. They all win in that department.
-Formats -> i miss cbr/cbz in that picture. Supported by others
– Kid friendly? Really? You chose this as argument? And eye fatigue to prove your points. Does kinda go for eink and all human eyes.
– Show a picture of trees and say “books are bad”? And use android? Probably supported for 1-2 years only.. Yeah – right.
Very unimpressive kickstarter if you used other eReaders before.
Looking at this tablet and what I’ve seen so far I’m impressed in what a new comer in the epaper display technologies has been able to pull off, although that said based on the comparisons shown by GoodEReader, and rather significant performance issues I personally dont see the average consumer well the enthusiast ebook reader picking it over the Eink units.
That said,I think it’s worth while to encourage competition, and seeing that the displays are by far the biggest cost drivers for this ebook readers, having a viable competitor in display tech would help. Who knows maybe amazon can release their next big ebook reader in Color and it not be eInk.
They made the E-Pad under a different company name. This says it all..
yes – i just read the comments on goodreader – and one from a Peter describes Reinkstone as having had several campaigns already – and changing their names after each.
Which sounds more then a bit fishy.
If this is somewhat through this is a nogo.
