My first Kobo Touch reader died

No, I cut the cables and removed the bulging battery. But I read somewhere it is a temperature sensor.

I'll probably do that.

For a book reader, it is a must. But I'd prefer standard AAA batteries or rechargeable equivalent.

Stops working. The seventh device is refused. These things phone home before they authorize a device to read books.

There is a chip with six legs, and another with also 6 legs, different form factor. The rest, no idea.

I read in bed, before sleep, and the usb cable on that thing is a nuisance while charging and reading.

Yes.

Huh.

Once I organized my ebooks with tags for theme, and then came an update and killed all my data. Even what books I had already read. All appeared as "new, unread".

You can search for a word (or string) on all your books. At least there is search, while there is nothing on paper books unless you write it down and organize it yourself, externally. Librarians know all about that. :-)

Waiting for appointments I usually take the ieee magazine, in paper :-)

And for reading comics.

The advantage of ebooks, is that the battery lasts weeks, and that you can read out in the sun. There is no brilliance from the screen at night, important when reading just before sleep.

My current one does colour, but akin to water colours. A bit faded, not solid.

I wouldn't care if it used AAA batteries.

Maybe I'll try that.

Yes, absolutely.

Yes, epubs are text. I would hate PDFs that don't contain actual text. Not searchable. And epub can reflow, adjust to your font choices of kind and size.

Absolutely.

Hum.

The magazine can be folded open :-)

Yes, but only works if there is a battery inside, still working even if not holding charge much.

I have several authors and I rotate them.

Hum. Yes.

Mmm.

Maybe they are already out there on some web to download. If they are modern enough.

Scanning books is a big chore. I keep postponing it.

I don't go that fast.

I enjoyed the 2001 book :-)

True.

That's fast. Mine takes a minute for page, no autofeed. I'm not at the unbinding stage, but thought about it.

Right. Maybe like the one we had at the photography lab at my uni residence.

Mmmm.

I should look out for those.

"The Many Worlds of 2001" is not a published work, but likely refers to the 1972 book "The Lost Worlds of 2001" by Arthur C. Clarke, which contains early drafts, behind-the-scenes notes, and alternative ideas from the collaborative process of creating the novel and the Stanley Kubrick film 2001: A Space Odyssey. The book offers insight into scriptwriting changes, production issues, and discarded concepts, providing "lost worlds" of ideas that did not make it into the final versions of the story and film.»

I just started "Time for the stars" from Heinlein yesterday. Next will be "Ghost brigades" from John Scalzi. I just ended "Dark Corners" from Ruth Rendell and before that "Death Is Now My Neighbour" from Colin Dexter. And waiting for "The Faith of Beasts" from James S. A. Corey.

:-D

:-D

Last one I enjoyed was "Sleeping Dogs", this last Sunday night.

I just looked at the photo instead of directly ad the tiny PCB, and noticed one of the components is labelled "NTC". Could be an NTC thermistor (Negative Temperature Coefficient).

If it's British, it's 'humour'...

I found some more information.

(I posted orig>

On

Wow.

Amazon has the two wire version (I would have to replace the PCB)

Aliexpres has the one I bought and that bulged some years later:

These are the instructions I followed the last time:

It is 3.7 volts, so I will probably rig three standard rechargeable batteries, size AA or AAA, in a battery holder, and connect it temporarily, so that I can remove the registration.

Oh. Well, mine are 1.2V cells, AA and AAA form factors.

I have seen higher voltages on a torch I have. But I have misplaced it and can not check.

I guess any 3.7v cell would do. But trying with the cells I already have saves money. I just have to activate the thing and do a factory reset. Then the thing is garbage, can be recycled.

Would be a problem if I have to connect the USB to the computer to do something. Besides, I don't remember if my bench supply goes that low, but I do remember the potentiometer had a will of his own, making the voltage go jumpy when trying to adjust it. And no, it was a new potentiometer, I built that unit myself.

ADE has no verification. Kobo itself, I'll have to look.

I just rigged up the connection and the device did power up.

The two last photos.

It worked and responded; I let it connect to the WiFi. I let it sync, it said it wanted to update itself, and I accepted. But then it stopped responding to the touch. It responded to the "home" physical button.

The battery icon went down to nearly discharged, so I connected the USB cable.

No response to the touch. At some point I heard a "clack!", which I thought would be one of the 3 AAA rechargeable batteries shifting position inside the holder, but later realized it was something electrical. No smells.

I rebooted the thing, it came back again, update done, but still not responding to the touch. Thus I can do nothing with it (I want to rescind the adobe login).

I will try recharging the batteries externally, but it seems I will not be able to progress.

I managed to power it up. I connected an external battery pack, a box with three AAA rechargeable battery, which seems to have the same voltage. I soldered the cables to the old battery micro-pcb (with a temp sensor, 3 cables out).

The kobo thing is robust, there was a clack which today I realized was a short with the kobo battery holder which is metallic, so today I wrapped that mini pcb in celo tape.

Yesterday it worked initially, then the touch screen stopped responding to the touch. I recharged the AAA batteries in their external charger, and tried again today. The thing did not power up. I connected the USB cable with the battery in "off" position, I saw a led coming up, but still no response. Then I powered ON the battery pack, and finally it booted. I followed the procedure to disable the ADE identity, then the Kobo identity, which was the purpose of the entire job. Success. I took photos of it all.
