Hello guys, Welcome to Being Engineers. Some times back I have posted a tutorial here in the Instructables on the topic of casting raspberry pi monitor, most specifically Raspbian OS screen to android mobile, as well as there we were able to control the pi from the mobile itself. It got quite some views and recently some people were facing problems completing the steps. The process is quite orthodox and takes a lot of time to connect each time. So I decided to put up a new tutorial which will be much easier to execute and more convenient on the go. In this method, you only need a power bank to connect to the Pi each time you want it to be. That means you can cast pi screen to your mobile anytime anywhere. No need of internet, no router, no monitor, just a power bank. But this method will only work with newer Raspberry Pi because they have the Wi-Fi chip build in and we will be using the WI-Fi only. But you can use older versions of Pi with the help of WiFi dongle.
