Quick Setup of CasaOS

Now we have enough information about the Casa, let’s try to install it. Before installing the casa, first boot your Raspberry Pi with Raspian OS. Use the Raspberry Pi imager tool to do that.

Once installed, the software opens the tool.

Next, choose the OS type.

Then select the drive. One of the great features of this tool is we can add the SSH and Wi-Fi credentials directly into the OS file, even without turning on the Raspberry Pi. For that, select the settings icon in the tool.

Next, start burning the OS into the SD card.

Once the writing is finished, insert the SD card into the Raspberry Pi.

Then power on the device. The first time it will take some time to boot and connect to Wi-Fi. In about 5–10 minutes look at your router status, and you can see there will be a new device connected to your router.

Next, use serial terminal software to communicate with SSH.

Then run this command to install the CasaOS.

curl -fsSL https://get.casaos.io | sudo bash

You will see this message on the terminal, and the entered command will try to install all the necessary components regarding the CasaOS.

Once the installation is finished, you will see this kind of message also the IP address of the Casa Server.

Next type the IP in your Brower, and you will see the CasaOS on screen.

And then click Go and enter your access details for the CasaOS.

Finally, you will see the beautiful home screen.

Next, click on the app store, and you can see there is a bunch of available apps.

 

Also, open the file manager, and you will see all the files of your Raspberry Pi,

Not only the system drive, but It will show you the removable drive also.

Wrap-Up

That’s all about the CasaOS, it’s a very beautiful, simple, and lightweight OS, right? And it also includes a bunch of apps, including Pihole, Plex, and many more.

Will see you in another tutorial.

Brushed DC Motor Speed Controller Using Radio Control (RC) Remote

This is a Brushed DC motor controller designed to control one brushed DC motor up to 5A. It can control the speed of the DC motor using a Radio Control (RC) System. This Arduino compatible hardware converts RC PWM signal into 0 to 100% duty cycle PWM which further drives high current load using MOSFET. The project consists of an Atmega328 microcontroller, and a gate driver optocoupler provides isolation between MOSFET and microcontroller circuit to prevent high voltage and noise traveling from the motor and related circuit to the microcontroller. The circuit can drive a motor up to 5A with a power supply of 12V to 40V DC. The board has the option to mount higher voltage and current MOSFET, which can drive higher Voltage and current load. In this case don’t install Q2, install Q1 MOSFET FDH3632, and replace diode D2 with a higher current diode.

Note: This board will work with any standard RC remote. In this project, we tested it with HOTRC DS-600 6CH 2.4GHz Radio System. Standard RC radio outputs is 50Hz – 1mS(1000uS) to 2mS(2000uS)

Arduino Programming

Arduino code is available as a download below and the user will able to test the board using this code. Feel free to modify the code as per requirement.
