Open Source Gift Ideas for the Holiday Season

It is the holiday season and a time to share and exchange presents. And what better way to share some love this holiday season than by giving your loved ones an open source gift. After meticulously going through all that is to offer, we have chosen the following open source gift recommendations.

Our judges panel assured us that one can never go wrong with these gifts. They are all sure winners. So lets see. We also reviewed what our users like to read on XenStreet and therefore were more inclined towards the gifts that you like. For example, our coverage of Linux Distros and Raspberry Pi were more popular than other posts. Hence, our inclination to find something around them.

The Zero Terminal – Pocket Computer that works!

The real joy of tinkering with Raspberry Pi is to build something nifty and fun. To hack a really whacky and crazy idea into a working prototype. That we all love and feel passionate about. Recently, we came across this amazing hand-held Linux Terminal called, The Zero Terminal, is built by the hacker codenamed NODE. His pocket sized computer actually works!

Intel Edison bites the dust – No more in IoT space

Has Intel finally thrown in the towel in the IoT space? Earlier this year, Intel announced that it will discontinue their IoT platforms namely, Galileo, Joule, and Edison. We wrote about Edison when it came out with the promise of really taking on the IoT space head on. However, it failed to create the momentum that was needed to take off. Alas, it never happened and Intel Edison bites the dust.

Raspberry Pi IoT devices have been imitated by others and numerous clones exist in the market. But many of these imitators do not seem to last long. Like Intel, they bite the dust when they lose momentum. We recently covered CHIP computer, which too is suffering from inability to build and ship their US$10 computer on a board to customers. Many such stories abound.

C.H.I.P. and Pi Zero W – US$10 dollar Computers

We love the little C.H.I.P. Single-board computer. And it boasts some really powerful specs for only US$9. Yes, only US$9. While Raspberry Pi is not far behind in competition with their own Pi Zero W, but we still love the little C.H.I.P. Both CHIP and Pi Zero are available for US$10 with eerily similar specs.

These somewhat really minuscule computers are even more powerful than the original Raspberry Pi that came out five years ago.

CHIP and Pi Zero W offer an opportunity for hobbyists to build even cooler gadgets with really cheap computers as compared to high end raspberry Pis. CHIP offers some wonderful products, including PocketCHIP, which is a fully portable computer in your pocket. It comes standard with battery, screen and a working keyboard for around US$70. Perfect for hackers, gamers or hobbyist to carry something around.

Three Raspberry Pi Powered Creative Learning Kits

Raspberry Pi is currently one of the hottest devices to build your own creative IoTs, computers and learning kits. But one of the biggest selling points of these kits is the price. Cheap, open source and easy-to-learn, creative kits make it great fun with kids and family alike.

The popularity of Raspberry Pi has made it possible for many other startups to use it as the basis for their commercial products. MyCroft, is one such creative device that we reviewed earlier that builds an Alexa like AI assistant on top of a Pi.

Popular Raspberry Pi Clones

IoT revolution and popularity had its roots in Raspberry Pi. This relatively inexpensive little computer on a board, had millions of tinkerers around the globe building thousands of interesting little gadgets. Almost all are open source. From a remote controlling a buggy to Baby Monitor to Music Box. You can follow some of the more promising ones online on Raspberry Pi website. This little device has inspired many raspberry pi clones.

Today, there are literally dozens of Raspberry Pi clones. Some even aptly named after a fruit like the original. So here we list some of the most promising ones out there with comparable price brackets that are easily procured online through major online shopping sites. They all run some form of Linux or Android. However, the most popular version of Linux is based on Debian distribution.

Mycroft – Open Source AIexa like Artificial Intelligence

Amazon’s Alexa, Apple’s Siri and Google Now have become our defacto assistants for most things mundane.  Making calls, setting appointments or reminders, streaming music, turn on lights, playing games among dozens of tasks are now handled by them.

But this space is still young, Microsoft’s Cortana, IBM’s Watson and a host of other tech giants are trying to make their mark. But as it stands today, all these platforms are built by billion dollar companies to be used on their propriety hardware/technology stack. That all has changed with the arrival of Mycroft.

Kano Kit – An idea worth betting the future of your kids education

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.

Building a Baby Monitor on Raspberry Pi – Part 1

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.
