DIY Bluetooth joystick adapter (8bitdo) adapter - raspberry-pi

I want to know is there a way we can program a Bluetooth dongle (NRF dongle, esp32 or even raspberry pi) to work as a Bluetooth adapter for PS, Xbox or Nintendo controllers. I found one product called 8bitdo. Very interesting product, it can connect between different controllers and platforms. Its like an universal adapter. I want to know is there any open source code available for this project. I'm new to embedded engineering. So, excuse me if I sound silly. But I'm curious about this project. If someone can tell me where to start, or give me some idea on how to do it, it will be helpful. Thank you.

Take a look here for Dualshock 4 (PS4) Controllers. Here's an already existing project using an ESP32 for a Dualshock3 (PS3) Controller.
But please use google next time, this took me only 1 minute to find.

How much can I pack into this Raspberry Pi project?

I've seen a lot of projects, tutorials and how-to's on the web regarding the Raspberry Pi.
I've just received my first Pi in the mail, and I can't wait to get tinkering with it.
Of course, doing any of these things is going to be a difficult process, however, as my experience with the Pi is next to none, I wondered about the capabilities of what I want to do with my first major project.
I'd like to be able to build an on-board computer for my car. I've seen several projects regarding this, and I've seen some good guides online.
However, none that I have seen will do EVERYTHING that I can think of....
I'm assuming that my 8GB SD card will be limited to only a selection of these specifications, however, here's a list of what I'd like the solution to be capable of, and if anyone knows any reason why this isn't possible, please give me a heads up :)
So...
I'd like a front-end GUI (on a 7" touchscreen monitor) with a menu to navigate the options, which will include
From this menu, I'd like to be able to select (and of course, run) the following:
Media center (I've seen things like XBMC etc.) - I'd like this to be capable of taking over the radio unit and playign mp3's etc (possibly from my iphone!?)
GPS/SatNav - I don't know how possible this is and I assume i'd need a 3G card or something...
Reverse parking camera (stick a webcam in the rear view window) etc (I've seen good tutorials for this)
Connect my phone with a bluetooth thingy(?) so that I can add a USB mic and play the receiver audio through my speakers (acting as a hands free kit)
I'll add more ideas too...
I'm not questioning if each of these individual specifications are possible, I am asking if they are all possible through one solution as a whole, with a GUI to navigate through them?
Thanks for any help.
Cal.
It is all possible, all in one bundle. 8gb is more than enough for everything, it'll only limit your music collection. The only question is: how much work are you able/capable of doing. That will be the limiting factor, not your Pi.
Short answer is yes, all exist and the pi can handle it. But you'll be writing a lot of custom software to make them interoperate.

Want to test Bonjour with 2 iphone/ipad

Apologies for such a silly question.
Please note I don't have Apple TV or any printer. I would like to get hold of the packet trace that takes place when bonjour (Discovery and Resolution phase) is in action. I need to get bonjour into action using just 2 iphone/ipad (I have a Wifi Network through which I could connect these iPad/iPod). Please suggest what application can I use to achieve this? I am a newbie in iOS world, and have no idea of apps related to bonjour.
Hope some of you could help.

Communication between two iOS devices

I am looking for a way to have one iPhone app send a message to another app on a different phone (sort of like a Sender-Receiver set up). I am looking for the best possible way to do this. Does anyone have any ideas and/or tutorials?
Thanks for the help.
You should use GameKit. It is super easy to send messages between two iOS devices using it. Here's a great tutorial: Game Kit. You can also get more information about it here from the docs: About Game Kit.
You communicate by creating an ad-hoc bluetooth or local wireless network.
lmirak provided insightful info about device communication(especially about GameKit). I would like to add one more solution. You can use WiFi network to do your device communication.
See the link or download the sample application from developer.apple
The sample application named as WiTap. It demonstrates how to achieve network communication between applications. Using Bonjour, the application both advertises itself on the local network and displays a list of other instances of this application on the network.
If your app is only going to run on iOS, then you should use the fantastic MultipeerConnectivity library. https://developer.apple.com/documentation/multipeerconnectivity
If you need a solution that will work cross-platform, then one way to accomplish this is using sockets and connecting over a local network. On iOS you can use CocoaAsyncPods for sockets and NetService for discovery.
Here is a basic example app that does this: https://github.com/brendaninnis/LocalNetworkingApp
, which I explain in great detail here: http://brendaninnis.ca/connect-nearby-devices-part-1.html

Using iPhone serial connection (pins 12 and 13)

Ok, so I've never done anything with serial connections before. But...
I just got an Arduino that I am trying to use to remotely launch model rockets. I have a 5 volt relay that I can control with the Arduino's digital out.
Now, I want connect my iPhone's Tx to the Arduino's Rx and vice-versa. I would buy the iPhone breakout board from spark fun so I could connect it to the Arduino. (http://www.sparkfun.com/products/10645) I was thinking something along the lines of: when the phone gets a text or a call from a certain number, or maybe even just a bluetooth signal, it would tell the Arduino. But those are just ideas.
How can I actually send a signal from my iPhone? Are there xCode libraries to do this? My phone is jailbroken, so I am open to other non-apple ways for sending signals. But I am a novice programmer.
Thank you.
P.S. I'm new to Stack Overflow, and I would appreciate if you could help me. The first time I posted a question someone told me it wasn't on the right site. So please bear with me.
EDIT #1: Haha, I just read over this and it sounds like a cell phone bomb from a terrorist movie. I swear that's not what I'm doing. Just look at my avatar.
EDIT #2: I also have a Bluetooth dongle for the Arduino. But I honestly have no idea how to interface that with anything, it was $10 from China, so I thought I would buy it to keep my options open. But, regardless, it would be really cool to plug an iPhone into an Arduino.
You could buy a Redpark Serial Cable for iOS to connect the iPhone to your Arduino board over RS-232.
This book also seems to be helpful: iOS Sensor Apps with Arduino
EDIT:
Redpark FAQ: http://redpark.com/c2db9_FAQs.html
There is a SDK available for this serial cable.
You will have trouble writing communication software when trying to connect directly to the dock connector! The External Accessory Framework wont help you here unless your Arduino board has a special decoding chip for dock connector communication.
Have fun!
All I think you need to do is utilize the External Accessory framework. I'm not sure how well it will work for you, the library is meant to communicate with MFi approved accessories. I'd really like to hear how your results went, I am going to be conducting an experiment of my own using a break out board
I am in a similar boat as you, and I have successfully built my own serial cable using the podbreakout, and have implemented a serial class that supports reading / writing. I can confirm that I have read working, as I have tested it with my RFID reader. I am in the process of writing code that will send a command to the Arduino from the iPhone, and then have the Arduino perform a task based on the command.
Here is a document I put together on iDevice serial com,
https://docs.google.com/document/d/1Yi9_hcw8XSyYNCG2OJT9oHlTG-dC-Dnuc58VIULa81Q/edit?usp=sharing
and the serial class can be seen in the project I am working on.

Use iphone to remotely complete a circuit

I want to create IBAction for the iPhone or iPad that wirelessly or remotely cause a circuit to complete. So again. I am not sure what API I need to use. I need help to connect the IBAction to the process. Please any help would be appreciated.
The iPhone doesn't contain a specific API for controlling external devices. You need to refer instead to the user manual or data sheet of the device you are attempting to control.
If you use a networked device, such as the make controller or Ethernet shield on an arduino, you can use networking commands to control the circuit.
We can give more specific help if you explain more about what you are controlling, and whether you already have hardware to act as a gateway between the iPhone and the device you are controlling.
