The system works by sending actions to be performed through a server running on the Raspberry Pi. The server operates within the local network of a router. The actions currently supported are: executing commands, sending files, and simulating a mouse and keyboard.

The app works by connecting to the Raspberry Pi connected to the Wi-Fi. The Raspberry Pi can connect to the Wi-Fi via Bluetooth. Once connected, the application will have two main parts: the app store and the Raspberry Pi page.

The store is simply a standard app store, but exclusively for Raspberry Pi apps or projects. Projects can include a guide to assemble them and a list of required products. These two features help new users by simplifying their experience and assist developers by allowing them to sell their products or share affiliate links.

The Raspberry Pi page will display the installed applications and information about the Raspberry Pi, such as storage and temperature. The installed apps will include a page with controls to interact with them. This page will be predefined by developers and will allow users to interact with the Raspberry Pi without connecting any peripherals or needing Linux knowledge. Users won’t be able to modify this page but can create their own interface using components from the different installed applications or by creating their own components if they are Linux-savvy. This allows new users to use the Raspberry Pi without any issues by simply pressing buttons or filling out forms, while more advanced users retain customization options or can perform unique actions.

There is still much work to be done, and I hope you like the idea. I don’t intend to take away the spirit of the Raspberry Pi but rather extend it to other people and make it easier for those of us who already use Raspberry Pis, without losing any features. If you want to see more, you can check it out here.

What features do you think I should include? It’s already planned to create a way for the Raspberry Pi to stream to a mobile device to view its screen or, for example, a security camera. I’m also considering adding a system where, when creating a personalized page with components from different apps, you could create a “compilation app.” This app would install the necessary applications and help users find synergies. For example, a user installing Pi-hole might also find it interesting to have Nextcloud on the same Raspberry Pi.

As I said, there’s still much to do. Anything you think should be included or seems necessary, feel free to comment here or on the link.

I'm using a raspberry pi 5 8GB

What I need help, with is I would like my car's logo which is my boot up logo to show up when the door opens which some of the newer cars have today, where the logo pops up on the infotainment screen.

I would also like the Kilometers/mileage to popup on this screen. 

How should I go about this? Any help would be much appreciated.

I was thinking do I use a battery pack for the raspberry pi which then this charges when the car is on? And and then the raspberry pi fully boots up when charging power is detected. 

Thanks in advance ☺️

I am new to Raspberry Pi. I am migrating an existing C# .NET Framework 5.4 based console application to C# .Net Core /7.0 (cross platform for Raspberry Pi). This application communicates with one of the portable device and data transfer using USB. My application has been compiled successfully in VS2022 in ARM64 bit. It’s executed perfectly fine in Windows environment. Then I have compiled in ARM64 release mode with 0 error.  When I copied and executed it in Raspberry Pi4 (Raspbian 64 bit OS) with .NET 7.0 environment. It give me the missing HID.dll error. I have tried to download the HID.dll error but still give me the same error. Might be the wrong version.

Error:

System.DllNotFoundException: Unable to load shared library 'hid.dll' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace.

Please help me for installing the correct version of HID.dll. I am not able to find the correct dll.

Thanks & Regards

To pay a tribute to the raspberry pi I created a video about the Raspberry Pi.

I used a rule called 99-my-usb-rule.rules in /etc/udev/rules.d

All the work I did and the error log are all in the attached image file
Can anyone help me?

My proposed circuit design:

Components:
Raspberry Pi 3B+

MG996R Servo (x12)
Spec Sheet:

Purchase Link: Amazon Canada, Amazon US, Amazon Germany for those in Europe 

20A 300W Buck Converter
Spec Sheet:

Purchase Link: Amazon Canada, Amazon US, Amazon Germany for those in Europe


Justifications:
- Each of the voltage regulators I chose is rated for 20 amps max draw, so I figured I would have to use 2 for this project. This might be a stupid idea (will this even work?), but I found it difficult to find any voltage regulators that could handle the total current draw of this system

- Each servo draws a maximum of 2.5 amps at stall, so in a worst-case scenario, they will draw a maximum of 30 amps. Split between the two regulators we should be well within the manufacturer's specs (they recommend sustained operation to be at 15 amps or less)

Question:
Ideally, I would like to be able to drive my servos closer to their max voltage (7V), but I am concerned that I will fry my Pi through the GPIO connections that control the servos. (I understand the power and control pins on the servos are isolated, but I have heard horror stories). Additionally, I have considered using a PCA9685 Servo driver, but I could not find information on the max current that this hat can handle and it seems kind of redundant given the Pi can control the 12 servos with the built-in GPIO pins.

Given all this, would it be possible to step down the voltage to 7V using my existing Buck Converter setup, then step the voltage down a second time for just the Pi?

More importantly, is my current design with two buck converters even feasible?

I would really appreciate if anyone can help me solve this problem.
