Kindle Pi

I got a new toy yesterday, so I felt compelled to get it working with my old toy. Here are a couple of pictures of the rev. B Raspberry Pi running Raspbian configured for adb/fastboot use with the Kindle Fire. It's nothing earth-shattering. It just works like you'd expect any other linux box to function. I'm not sure if anybody would actually buy one for this express purpose, but it's nice to know that it does work.

Very cool kinfauns! Also I'm glad your desktop doesn't look much different than mine with the wires going everywhere . My wife asks how I can get anything accomplished I just say "what I know where everything is".

Pretty cool that you can actually order Pi's now. They were backordered for the longest...
What would be cool is if you get the android and the pi talking so you can use the pi to operate the gpio pins and fire some relays or take sensor data. What are your plans for the pi...?

My desk is clean! It's the raspberry pi that caused all the wires to get out of place.

I had no specific plans for it when I ordered it. Coupling it to an android device wasn't really anything I had in mind. Now that I have it in hand, I plan to see if it's viable to use it as a backup server and a personal mail/imap server. If that doesn't work out, I want to hook it up to a high water sensor in my sump pump pit to send out a set of email/SMS warnings to notify me of trouble. I'll probably just play around with it some, learn some new things and see if any good ideas pop up.

I believe I see an unusually large buckyball cube in the picture. You do have an affinity for cool stuff.

That's pretty sweet. I heard about the, oh what is it called, raspberry pi(?) a few months ago. That thing is pretty cool. Also, when did you get a kindle fire? Didn't you sell yours or something?

It's a very capable little device for the money. Not fast, but I don't think anybody would buy it looking for speed.
I sold my KFs when I got the N7, but I missed tinkering around with it and found myself looking around on Craigslist for one soon thereafter. A guy in the town over was selling one that was barely touched for $80. I drove over and made the deal.
He threw in a case that I've never used and probably never will use. Maybe I'll start a new thread offering it for free to a random person who posts a response.

Yeah, it's a 12^3. I wanted to size up to a 16^3 with it being a power of 2 and all. Then I realized how many buckyballs that would actually take to make and I had to hold myself back before it got too crazy. :silly:

[Q] Looking for Volunteers to Open their NST without Glowlight

For those of you who do not know, I am on a mission to build Android 2.2 for the Nook Simple Touch.
Bill Detweiler at Techreports did tear downs of the Simple Touch and the Simple Touch with Glowlight.
In his review of the Glowlight he mentions several chips that he does not mention in his review of the regular Simple Touch. It is not clear whether they are not present in the regular NST or whether they are just not mentioned.

I am a complete Klutz, and opening my NST would almost certainly be a disaster, LOL. I am looking for a couple people willing to pop open their NST without Glow and see if the following chips are or are not on the motherboard:
Chip Markings:
CKP TI A3T9
Texas Instruments BQ27520 System-Side Impedance Track Fuel Gauge
Texas Instruments 2624I
Texas Instruments YE04 18K G4 A919
Added question 08/31/2013: It would also be helpful to know if the traces on the motherboard go from the display connector to the ispMACH ZE or something else.

I might be able to open it up and have a look at it as soon as it gets shipped to me.
Will post here if nobody else does till then.

Bill Detwiler of TechRepublic did the following teardowns:
Nook Simple Touch (without Glowlight)
Nook Simple Touch with Glowlight
I've taken mine apart a zillion times.
A (previously done) flatbed scan of the PCB is attached.
The two PCB appear practically identical.
The difference seems to be a few extra components in the upper left corner.
(The white connector is my own addition, a console UART connection.)
Note that there is a major difference between package markings and IC numbers.
The "CKP" is actually a bq24072
In short, I'd just go with the Nook Glow and presume that it would all work on the Touch.

THANKS Renata

Hey, Renate!! Thank you so much for your response. The clue on the CKP chip helped me nail that one down. Using the same skills, I eliminated the 4th chip from the list, 'cause it is the same mux demux he mentioned in the NST article. I was also able to fill in more details on the other two chips in the list.
I am operating on the assumption that the chips are on the board. I am just looking for confirmation of that, lol.
Thank you again!

bump. still looking for volunteers to confirm these chips for me...

I've also been digging around to do some building; the stuff I've spotted so far (this is a without-glowlight) around the battery connector are two chips,
one labelled 'ckp ti 191 a0le' - I reckon that is a BQ 24072 charging chip (see http://www.ti.com/lit/ds/symlink/bq24073.pdf) - the 73 is supposed to be labelled ckq as far as I can tell.
The other chip I can see just next to it I think is labelled as BQ27506 but it's a bit on the damn small side; I'm assuming we've actually
got that rather than the BQ27520 that the source says but maybe it's just hiding.

Longshot -->Spare parts source for a Yoga Tablet 2 830F - 8"?

Does anyone have any ideas where I can find replacement parts for this thing? Specifically I'm seeking the little flex board that houses the micro USB connector. It's my wife's tablet and she's hard on connectors. I've repaired several of her phones but this tablet is more obscure it seems.
I've been searching based on printing on the part and I can find a pic of it from google image using "lenovo Blade2_8" but the link to a russian website doesn't go to the part shown.
It looks like this:

this one or this search and i think you can find more
hardware manual

Thank You! I searched everywhere I could think of; not sure how I missed the eBay one, that's my goto source for most things like this.
I'm hoping that it is the bum part as the device still recognizes that a USB is plugged in momentarily. It's a $50 guess.

wow... that ebay seller sure has a good margin considering the import statement found here it costs 1.5 us dollars per unit (not even 2), yet the seller is the one who makes the price, if you have someone who can buy from and send it to you from china... or some friend in russia for this one i am sure is way cheaper ... or just go to a near lenovo support service that does hw repairs and beg for it or tell them that you will pay double the price (3 usd)
you can also search for the part yourself, i just linked the fast found search results

If I were you, I would order a new USB connector and then solder it to the ribbon in place of the old one. It is tricky, but doable. Just need a fine tip soldering iron and some helping hands and a pair of tweezers. You do not want to let the ribbon cable heat up and melt. That would be the end. But, like I said, it can be done.

Success!
I bought and replaced the whole part and it works, charging as normal.
The $50 price tag was steep for a part that probably cost $0.10 in China but, whatever; that's why I work . And my wife is happy now. So I'll consider it a worthy investment.
Jaytronics - I usually do OK fixing my own stuff but I've never been any good at soldering. I'm shaky on a good day and I don't get much practice. I can get it done on larger things but on something that size I'd probably bridge 2 pins or something. I thought about trying it when I failed to find the whole piece but doubt won.
Thanks for the input guys. XDA saves the day again.
Now if I can just find a root and ROM for it.... it doesn't play with Hulu well on stock ROM.

Building own Android Head Unit

Chees Folks,
i wanna start a project and hope for an exchange of knowledge. First of all i wanna introduce myself. Im Pat, 27 years old from Germany. I have an BMW 3 (E46) with a Pumpkin Android Headunit (famous RK3188). Tbh the head unit is really slow and i thought: "Why not build a whole new head unit by myself?". I'm experienced in electronics and maybe a little bit of programing.
I thought about the following parts to realize the Project:
As Mainboard the Pine64 Rock64 - Advantages: Full Android support, Based on the Raspberry Pi, 4GB RAM, a lot of modules are available like 7" Touchscreen, external soundcard, GPS module, FM module, WiFi module and i also found a nice module to emulate my Steering Wheel Keys without big effort to it.
The challenging part comes with the bluetooth module. With a little investigation i found out, that you need a special bluetooth module that comes with the profiles: HSP, HFP, AD2P and so on.... Now the big question! How can i find an app for android that works with the module and let me manage the connections, make phone calls, transfer contacts and play music from my mobilephone? I guess you know what kind of app i am talking about. The common Android HU like Eresin, Pumpkin, Xtron, JOYING have these bluetooth managing apps (see screenshot)

I mean i could try to use one of these apps, but presumably it wont work cause of the different device. Maybe one of you can help and is interested in building a system that is usable for anyone.
Best regards!

You might take a look at this project.

Yes is saw this thread but unfortunately the creator didn't answer for about 3 Months and as i see the progress is really slow there. But sounds very interesting. Thanks for the hint

Actually, the PINE64 board is not really fast (Quad-Core A53 CPU, the usual PX5 head units have Octa-Cora A53). Considering all the effort you would have with getting something custom to a useable state, it's probably much easier and cheaper to try one of the new PX6 units for the E46 (with much faster A72 cores) first.

Im open for different boards in my configuration but i dont want a new Android Head Unit. I want to build it on my own which is more updatable in future than these common Units.

Unfortunately, I cannot post a link, but if you search for "hikey960-car gitlab" on Google, you will find details on the prototype of that project which may be of interest.

That one is from Adam Serbinski.
The link I referred to is from 96carboard aka ibdroid aka luciusfox aka doitright aka Mukesh (and a few other aliases) and continues here
I did not check and do not know if doitright is working on the first one too.
Edit: After further examination they all work on the same tree.
Edit2: After further examination I think that Adam Serbinsky is one of the many aliases doitright (96carboard) is using.

Chinese SmartWatch ... howto hack it

Hi guys
I am trying to understand how to customize my chinese smartwatch but I am having trouble understanding which HW and OS it runs.
This is the AliExpress link: https://www.aliexpress.com/item/1005004601404723.html?spm=a2g0o.order_detail.0.0.296bf19cmz1ASu
It seems an Amoled version, with 1.36" display and 390x390 pixels. It says also Realtek 8726d chip but I can't find anything so probably is not correct.
It works with the FitCloudPro app and no major issues there.
Anyone could help to try to understand which OS it has and if I can hack it?
It says (from within the phone) that the firmware is v1.04 1201 and UI ver 1256-05

Checking for what?
I just started myself, it is clearly possible to modify most watches but it is trial and error taking lots of time. There is another thread with more info where I am trying to dig deeper.

which is another one?
