It was not long ago, when Kano announced their intentions through a Kickstarter campaign to build a “computer and coding kit for all ages” powered by a Raspberry Pi. They asked for a meager US$100,000 to achieve their ambitious goal. The idea was an instant hit with backers. Within a short time, Kano amassed over 13,000 backers which ultimately resulted in 1.5million dollars successfully raised for the project!
The kit consists of a Raspberry Pi computer, hooked with a speaker, a wireless keyboard and connected to the internet through Wifi. The computer can be connected to any monitor/LCD screen through the provided HDMI cable.
In order for us to build a successful baby monitor, we need our Raspberry Pi to perform the following tasks:
- Capture live video feed of the baby
- Stream live video feed to browser to be viewable by any device (Phone, Tablet, PC etc)
- Capture live video feed and save it onto a hard drive for later viewing (Nanny Cam)
- Capture audio (optional) of the baby and stream it. For me, this is not a high priority.
We need the following hardware tools to build our baby monitor:
- Raspberry Pi + Casing + Power supply (or battery pack)
- Pi Camera + Casing (Some people have converted their USB webcams to do this, but I prefer the Pi Camera for this tutorial
- SD Card preferably 8GB with Raspbian installed on it.
- Wifi USB dongle (incase if you do not want to use the ethernet port for LAN connectivity)
- A micro hard drive or a USB flash drive for video recording (optional)
The above items can be easily purchased from dozens of vendors across the globe and information can be sourced from Raspberry Pi website.
In case if you plan to set your Raspberry Pi with a static IP address, then follow the steps listed below:
Kindly make sure that you are logged into Raspberry Pi on command line (console or SSH) before proceeding.

In an era of mobile computing, Internet of things and collapsing PC sales, one computer keeps surprising its competitors by outselling many established brands. Raspberry Pi, is a credit card sized single board minuscule computer which has sold well over 2 million in its first 20 months of launch and still going strong.
The devices are loved by not only computer geeks who are building amazing products out of it, but are also found on college campuses, school labs, home automation and even powering websites and supercomputers of sort out there. It seems only our imagination is the limit.
Google itself donated over 15,000 of these devices to UK schools for kids to play and learn computing. And has also open source developed software development kit for children to learn programming.
Watching this video you will feel how innovative and genius some of us are. Look at them, they have stacked 64 of RaspberryPi’s US$25 dollar computers into a supercomputer of some sort. It boasts a memory of 1TB by cobbling together 16GB SD cards in each of the computers running Linux. And what is more amazing is that it is housed in Lego brick casing. Wow.
If you feel like building your own Supercomputer out of these minuscule computers, the professors at University of Southampton have provided a guide and can be downloaded from their website here.
