The phone will run Android with F-Droid app store (no GMS), and most resources used to make the phone will be made available publicly, include KiCad schematics and PCB layout, Gerber files, 3D printable designs compatible with FreeCAD, and Android source code. There will be some binary blobs for GPU, model, WiFi & Bluetooth, GPS, camera, etc   1Sheeld Arduino Shield Leverages Your Android Smartphone Hardware. Study Shows Octa Core Processors Bring Little Over Quad Core Processors in Mobile Devices. LG V20 Android Smartphone is Powered by Qualcomm Snapdragon Processor. Xiaomi Mi A1 Smartphone Review – Part 2: Android Firmware. CategoriesAndroid, Hardware, Qualcomm Snapdragon, Video. This is a list of mobile phones with open-source operating systems. Some hardware components used in phones require drivers (firmware) to run. For many components, only proprietary drivers are available (open source phones usually seek components with open drivers.) If these drivers are not updatable and do not have control over any other part of the phone, they might be considered equivalent to part of the hardware. However, these conditions do not hold for cellular modems. Android Image & Camera Filters Based on OpenGL.. Contribute to wysaid/android-gpuimage-plus development by creating an account on GitHub. The only significant development of the last couple of years, that I see, are microphone arrays imags than one mic. Now you will not have any worries regarding file format not supported and all. A million dollars is chump change in that business. What is the weight of your Phone open hardware android smartphone image battery? DragonBox Pyra Mobile Edition [13]. Use a local battery.

Sorry for the change. I think it's better to do this right now. I have mixed feelings about this, to be honest. I am sad to see it go. So — why did I decide on the Snapdragon ? To answer that, let me tell you what I think are my responsibilities are in this project:.

This project includes certification plans of all sort. The largest number of folks who are likely to back this project will come from USA. My subscription list tells me that. A cursory scan on a few projects — and surely projects in the DIY Electronics category — will help prove that too.

So — USA is an important geography for this project. Countless projects have been delayed due to cellular certifications. And famous ones. I am talking about people with deep pockets. I have a great plan for predictable, on time delivery — if I stick to the Snapdragon Another equally important reason is that I am unable to see who is buying the Snapdragon , and for what purposes.

This project is expected to deliver in Dec-Jan window for the early orders. I intend to do a great job — and that means that I should expect more people backing me. With larger volumes, and longer life, comes a predictability requirement. The Snapdragon also has most of the goodness of the — two independent displays, two cameras wee bit less powerful , USB 3.

What you lose is what I have mentioned earlier. Things kind of evolved to reach the current state. This post is an attempt to explain what has happened till now, and how we intend to change things in the future. Smartphones are based on SoCs — basically a lot packed into a single chip. Reference designs also include other parts required to build the full phone: RAM, storage, peripherals, connectors, antenna designs, and everything including the enclosure of the phone.

Reference designs represent reasonably tuned solutions, from a hardware, software, cost and performance perspective that is saying quite a lot in one sentence, by the way!

Making a smartphone is a tight exercise in space optimization too. Mass market consumer devices essentially go through an aggressive BOM optimization, which eliminates unnecessary components — down to the lowly resistors.

Smartphones are designed to sell in the millions. Even a few wasted resistors are a no-no at that scale. Reference designs are the secret to the flood of devices you have been seeing in the market for the past N years. We wanted to create a design that would allow us to build a variety of devices using a standard set of components. Before I get down to explaining each piece, here is the color coding used in the block diagrams in this post:.

I've been looking for something like this project for a long time, but not very actively, so looks like I missed the kickstarter by a year and a half. I'd also need a 60x75mm screen which is a separate problem What are the options for a project like this?

Could the v2 be produced at smaller volumes for a higher price? Could you take an existing popular phone motherboard and just produce adapter boards and documentation? Are you sure? I know I'm a bit late to the party, and this may not even still be supported, but, if it is, is there a possibility to provide support for newer Android versions such a Android 10 and on. S I don't know anything about this phone stuff.

Would be nice to see a phone that supports M. Thanks for this, davedarko! Looks like you made this happen?? Kite is about democracy.. I don't need to plug maker stuff on my phone or in my phone. Bluethooth and Wlan modules are dirt cheap. I don't want a phone with alternative hardware. I want a phone with alternative software. In particular, I would like to have a phone with a native Linux distribution with long term support, so that I don't have to worry about security updates after just two years.

Then, you can't sell software and you can't make money with selling phones to the same guy every two years. And that's is why, in my opinion, such a phone must be open source to quite some degree, since no company is making one; except for very expensive ones. IMHO the hardware components don't have to upgradeable.

I haven't replaced my phone for over 6 years now; I didn't need to. As a consequence, I am not even affected by most of nowadays security issues. The android on my phone is just to old, haha. Lars R. If you need a Linux distribution supported directly, then the Librem 5 is a good alternative to look at.

That's not me "recommending" them, but just saying that it's a possibility. A key feature of KitePhone is the battery is in your control. Use a local battery. Change it after two years. Upgradability of hardware is important, IMO. It is a key design feature of Kite v2. Thanks for the hint. At the moment, it looks to me as if the Librem 5 will be quite expensive whenever it will be available.

Replacing stuff is important, I agree. But I personally do not need to upgrade components all the time. What should I upgrade with? The only significant development of the last couple of years, that I see, are microphone arrays more than one mic. But is connecting multiple mics even possible with your base board I don't think google maps runs on a Raspberry Pi. Pi does not have a GPS, right?

In the minimal configuration, a KitePhone weighs approx grams. Upgrades may not be required, I agree with you. There are many things you can "upgrade" - e. In our concept, the idea of "upgrade" applies only to the base board - Kiteboard. Everything else is "configurable". The KiteBoard tightly integrates most of the specs of a phone. So, upgrade gives a performance benefit to those who crave it.

The connectors on Kite v2 will be forward compatible to achieve this. Regarding the "being incharge with Android part" - that is very much possible with Kite. Kite does not ship with "Google Apps". It comes unlocked in every way. All parts of Android are open to modification, so you can remove all traces of dependency on google infrastructure, if you so wish.

Hi fabian - not sure what you mean by "blocking phone"? We plan to start with Android, Everything is open here Would be nice if it was a single board rather then needing a breakout board for the pins. This would hopefully make the board more compact or make the profile of the device not as thick.

If the screen could connect directly to the board with out going through a controller board it would also help with keeping the profile of the device thinner as well. I know its going to be impossible to get anywhere near the thinness of current mobile phones, and this board is more then just a phone. But these changes would go a long way to make custom devices made with kite fit in a pocket. Looking forward to the kickstarter regardless. Lexie Dostal for some reason, hackaday isn't allowing me to hit "reply" on your message.

So here it is :. You are right about the single board. However, that comes with a drawback : we get tied to a single display or camera. With generic connectors, we keep the main board free of such dependencies. That said, I do agree that lowering the thickness is not only desirable, but an often requested change! A possible solution is to have all the required boards lie on a single plane - rather than being stacked.

My hope is to get the thickness of the device down to the range mm with such changes - if not better.

Reducing the thickness is truly is a multi-dimensional problem : we have various off-the-shelf components of various sizes - and all of them play a role in the current form factor. We will try our best here. I understand having a generic connector would make the board work with more devices in the future.

Another nice feature would be having analog inputs. Always seems strange to me that the PI didn't come with any. A lot of people were worried about the specs of V1 me included , I just saw on the product description that V2 will be using Snapdragon I think those specs should be more then enough for most people looking for a DIY board like this.

Lexie Dostal I guess hackaday doesn't like deep nesting for comments Thanks for your wishes. Coming soon to Kickstarter -- hopefully the week after next Good to hear that the Snapdragon works for you! Analog inputs would be really nice to have. How many channels would be sufficient in your opinion?

We could implement this by adding a discrete ADC chip on the expansion board. I think the extra cost could be well worth it - in terms of allowing users to do stuff without adding an extra microcontroller just to get an analog input working. Ahmad Shrif 8 would be amazing, but 4 would be the smallest amount that would still be useful IMO.

I plan on adding analogs joysticks to my kite project, I'm fine using ADC to get more analog inputs if need be. But 4 would go a long way to making the base board more useful for everyone. Lexie Dostal I think this requires some careful thought, then. Looks like the beginning of a stretch goal to me :. If you really need 8, you could use two of those ADS boards. All these boards are small - so you will end up with a great solution.

Do any of these solutions work for you? Was more bringing up the suggestion incase the chip you are using for the GPIO comes with some analog inputs already and could be broken out. Lexie Dostal Oh I see! I can't speak about the Pi, but I can offer some insights about my board. However, exposing these to users can be problematic, for at-least a couple of reasons:. Chances of damaging the SoC in unpredictable ways are high - when a user feeds a higher voltage by mistake.

With an ADC on the expansion board, if something goes wrong, only the expansion board is impacted. Less of a problem, as the expansion board is cheap, and something anyone can replicate easily.

An off-the-shelf ADC can easily outperform the internal one, in a very safe, well defined manner. I had a good opportunity to seen these devices up close in Bangalore during a meetup with Shree Kumar. The design is fantastic and the modularity is something all of us hackers would love to have.

This is the Google Ara beater phone we've all been waiting for. Can't wait. Thanks a lot, Anool. Always a pleasure meeting you! Very soon we are coming.

I need to update the page too - caught up making video and plans. More updates surely next week! Wow, this is a very cool device! Do you use it as your everyday smartphone? What is the battery life? Do you have any estimations on how much it will cost? Can it run something other than android? I have used it as an everyday smartphone for about a month. Battery life is about as good as a consumer phone. We are planning to put this up on Kickstarter soon.

Also, watch out for an update I will make later today, on this page. I am quite sure you will like that! Yes, it can run Linux I am catching up on a lot of documentation. Will get to that - hopefully next week. Why is it running an older version of Android? If it isn't powerful enough to handle it could you try Android Go? Our demos are running on Android L at the moment. A bigger reason, though, is that we are putting all our efforts towards our concept of modularity - interfacing various types of hardware, finding good use cases, making demos, spreading the word, and getting feedback.

That's why the older version of Android. However, we do understand the value of upgrades. We are planning to address this in time for our Kickstarter campaign.
