I will be showing you how to build a wifi robot from scratch. It is a very straight forward project and can easily be handled by a intermediate robot builder. To complete the robot, it will take a couple of hours. I also attached the android phone with this app ip camera with this robo and connected to the wifi to see live video feed. We need to reduce `Beacon Interval` to 40 instead of 100 (default) if we are using wifi router to command robo with pc/laptop to see real time effect.Continue reading

First, add the GPG key for the official Docker repository to the system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add the Docker repository to APT sources:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Next, update the package database with the Docker packages from the newly added repo:

sudo apt-get update

Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:

apt-cache policy docker-ce

Now Install

sudo apt-get install -y docker-ce

Check Status

sudo systemctl status docker

Hi all,

Its something not very new, but quite young for me. I tried to make search Engin like google and yahoo. Its really not very easy to make one. It is also not very useful for you people until it is mature enough to answer your queries. It may take some weeks and lot of processing power to do that. It’s continuously increasing its database. You can see more better results every minute. And its fast enough to give it a try. You can ask any thing you want. Here is the link https://bringmefast.com

This is like copy of source-code of crawler that is used for collecting data form web.

and I can say I saved a lot of money not buying a costly media server for home and made it myself. Just happy its ready to dance. So many ideas I have thought to work on. Will be posting about them soon. And I tried this server with HD movie it just showed a little flicker in one of the 4 little cores. I couldn’t believe it could handle that much load. So I hope for personal use I wont have to face crashing. It is having a nice fan attached for air suction. Guy u can comment if u got any questions.
