If you feel like enhancing it further you can slot in a 32GB SD Card. There is 8GB of internal storage, which i s double the standard amount that ships with most e-readers. Underneath the hood is a Quad-Core Cortex A9 up to 1.6 GHz processor and 512MB of RAM. There is a large demographic of people who ride public transit and are holding onto a pole or guard rail with one hand and read with the other. I think page turn buttons are tremendous on e-readers. The back of the Prime has a grooved contour that is meant to assist in holding it with one hand. The Prime has buttons on the left and right side, which means you can hold it with one hand and quickly flip pages. #Inkbook large screen manual#Many companies have abandoned manual page turn buttons and rely exclusively on the touchscreen to turn the pages of an e-book. You can read in the dark via the front-lit display and it has 8 LED lights, which provides great illumination that is evenly distributed across the screen. The screen is completely flush with the bezel, this makes it easier to use the touchscreen. The InkBook Prime features a six inch e-Ink Carta touchscreen with a resolution of 1024 x 758 and 212 PPI. The overall build quality premium device is really solid and it won a Red Dot award for industrial design. Those two sources in aggregate and a Saturday should be all you need for a one off.Arta Tech has been developing e-readers for a number of years and have scored a major victory with the InkBook Prime. If you have issues with that guy's build, this dude consistently has some of the best documented hardware hacks ever. (Each pixel with the characteristics of an N channel MOSFET.) Acting as the source on the FET - continuously driving "on" for each "frame render" (it's just latched in from a shift register), and the horizontal pixels corresponds to the vertical pixels (which is just a shift register pushing data for each render). The only thing you have to watch out for is quiescent current, not only for the obvious reasons (leakage = bad), but also because even a minimal amount of voltage drop 'across the FET' will fade out the image, so its double bad. Everything else are jellybeans you'll have lying around (except maybe those inductors). (I don't like his value choices for those caps around U4 and U5, but the rest of the design is so well done and I'd imagine he used SPICE and tested every node, so I'm going to just defer to his design, since I'm not an EE haha). Some LT standard (not as standard as the LM317 or 7805, but close) will switch both rails no sweat, all day, then use 2 standard LDOs will get get your -25 up to -15 and regulate your +25 down to +15. This guy did it for what looks to be under 10 bucks in parts. It needs a jellybean boost converter to get up to the +/- 25V a few tens of mA. That's the only 'strange' thing about it is the voltages as you mentioned (well that and the somewhat rare flat-flex ribbon used). #Inkbook large screen driver#I mean, someone in the 'maker community' has a high probability of having some difficulty, but my 12 year old cousin could build the driver on protoboard, no issues, and it's not like he's worked through 2nd order diff non-homogeneous eq's ). 8" eInk Pearl with front-light for $250 (I've heard great things about this company too) I don't have one but I've heard nothing but good things about support from Onyx and let's be honest making an e-reader isn't the most complicated thing out there so odds are you won't need much tech support (you can buy a DX 9.7" replacement screen for ~65 and drive it with a uC almost trivially easily).Įdit: 8" for 179$ (not "genuine" e-Ink(tm)) You get the same Paperwhite tech, the ability to jot notes down with a stylus, and a significantly bigger screen. It looks like you're paying an extra $100 just to get back the side-buttons the Kindle fanatics demanded (it feels way more natural to press a button than make a slide motion, to the point where you don't even realize you're pressing the button after a few pages of immersive reading, unlike the slide action which breaks the continuity - the same reason why I keep my 3rd gen around).įor $100 more, the Onyx BOOX N96 is definitely the best buy out there right now for that larger form factor. I was waiting for this release for ages, but I see no reason to buy it. I have 3 Kindles - one third gen for reading novels in one hand (I don't have particularly large hands but I can palm the 6" while using my thumb to move to the next page by clenching my hand), one PaperWhite for night reading, and one Kindle DX from ~5 years ago that I still use for PDF's.īelieve it or not there's a huge scene for people who love the 8-9" form-factor. I'm an e-reader fanatic, having bought a total of six for myself and friends/family over the years.
