Building An Open Hardware EBook Reader
Read this article about a guy building an open hardware ebook reader. I wouldn't be likely to build one myself, but I like the ambition.
There's already work being done on open source software. |

It's not hard and most of the needed software has been available for years open source.
The problem is cost, especially a decent eink screen. A decent case is harder than a PCB. Certainly having decent battery life by having the system mostly sleep apart from touch and buttons needs thought. I'd use a tablet SoC for main part and a separate PIC to manage touch screen & buttons. I'd use IR too. It would only scan properly when an initial touch is detected. I'd use AAA or AA NiMH so if camping with no charging you can put in Alkaline cells. I'd design the cover flap as part of the case because otherwise a case is adding more thickness at the back and sides. I think putting extended descriptions rather than part ID on the PCB silk screen is a waste. It's an ereader! Put all the HW docs in the onboard user manual. The silk screen info on a bare PCB isn't enough to build one anyway. |

I understand the drive to build a reader that won't leak information to a manufacturer/bookseller, but does this have to happen on open hardware? Wouldn't it be simpler to root an existing reader and just install software on it? (the reader would have the advantage of coming with a pre-built case, too)
Any idea how costly such a reader might be? (I'm half wondering if this might make a viable inderdisciplinary project for students in my university) |

Being naturally lazy, I will occasionally turn on the WiFi on my Kobo and buy a book from where I stand (I did this from Norway where I was on holiday last summer - finished a book, bought the next in the series right there). But then, well-made open source software could do this, without the risk of giving Kobo (or any other reseller) get a peek at my library and whatever I've been reading at which speed. |

The most expensive ongoing item in volume is the screen. Far more than every other part together. The PCB can be quite small, much smaller than example. PCB size and number of layers sets the price. Likely about $15. Bookshops / ereader Vendors: 1) In EU there is now GDPR. You have to be asked to opt in. Kobo seem to have at least added options. However Google in the past added "disable tracking" options that actually didn't stop tracking. 2) Disable WiFi. Only use USB transfer. You can enable WiFi at home if you block the domains on your router. Not all routers allow that, nor are people expert at doing it. 3) Don't buy ANY TV, eReader etc (only phones/tablets) using Android, or if you do never connect it to the Internet. Don't buy IoT stuff that needs a internet connection to work (Nest, Amazon doorbells). One security camera sold by a US retail chain now is bricked due to turning off of servers. Amazon and Google are the two worst risks due to size. Also the larger companies tend to ignore laws and ethics unless fined painfully. Next will be making directors, chairpersons, boards personally liable. EU will increase the regulation and oversight to protect consumers. US is more concerned with a level playing field between big USA corporations, though California State is making progress despite tens of millions of Dollars spent in lobbying by big corporations in USA. Open PC, open Phone, open Tablet sales are miniscule. There is no "open TV set", TV set solution is to drive "smart" features via laptop, phone, tablet (HDMI is best), never use WiFi/Ethernet direct. |

I would just love something that is like the nook hardware but runs simple, tweakable, software and is really built for those of us that sideload only.
I don’t want or need a book or App Store |

You can root a Nook eink ereader.

If I am travelling, can I buy books with my Kobo that are geo-restricted in my home country? I live in the US, but went to Japan earlier this year. Never thought of turning on the Kobo wifi to see what came up in the store. |

I seem to remember that my Kobo account remembers where I live, and won't let me buy books that are not for sale in France. Tried this from Scotland once I think.

My daughter's experience in Japan last month suggests that you can only buy books for the country your Kobo/Kobo account is set to. She had to have something to do between catching rugby games.

If memory serves you can tell Kobo via your account where you live, lying if you wanna, because they don’t check. Not sure how it handles credit cards and payment though. I also could be misremembering

You can use a fake email address that doesn't even work for Kobo registrations. The minimum for Amazon is a real working email address and an Amazon gift voucher to avoid giving them card/bank details. No address needed in either case. The ebook purchases on Kindle can be funded by gift vouchers.
Both ereaders can use out of copyright free books (might be over 70,000 PD, at least 10K "good ones") or books bought from Smashwords. I do sometimes buy ebooks from Amazon, download to PC for USB transfer and use my kindle's serial number to read them on my Kobo or Sony ereaders via Calibre. Publishers can decide to be DRM free on Amazon, though Amazon "breaks" that with KFX. Last edited by Quoth; 11-08-2019 at 04:07 AM. |
