Arduino and Raspberry Pi are great, well-utilized DIY boards for hacking just about anything you want to design. But if you’re looking for an alternate hacker board, here are seven that Steve Nelson, Freescale’s director of ecosystem and marketing programs, presented at this week’s Designers of Things (DoT) conference.
With some starting below the $20 mark, these Freescale-enabled, alternative hacker boards are community-supported and allow the transition to low-cost commercial volume manufacturing while still being compatible and easy-to-use, according to Nelson.

The Wireless Inventors Kit for the Raspberry Pi (RasWIK) is an exciting and affordable addition to the Raspberry Pi. RasWIK demonstrates that with our leading edge technology anyone (and we mean anyone) can build wireless sensors and actuators , you do not need huge experience, a degree or even any tools. We show you even how to connect the devices you build to “the Internet of Things” (IoT) service providers such as Xively.
Getting started is just 5 simple steps:
1. Insert the preconfigured SD card to your Pi
2. Plug in the Slice of Radio to the GPIO connector
3. Turn on the Pi
4. Power the XinoRF development board
5. Lauch the Python based example application on your Pi
Thats it!……..you are now past step one of your journey to wireless nirvana

For tinkerers and people who love programming complicated projects, devices like the Raspberry Pi and Arduino are amazing, but for those without technical knowledge, they can be a terrifying proposition. A new device called Verve 2 aims to bring the functionality of these devices to the masses without the need for programming skills.
The crux of a lot of cool projects you see developed using Arduino is the device itself, along with some connected sensors. From there, someone with electronics and programming knowledge writes the code that tells the system what to do when the sensors detect something. The general idea for Verve 2 is the same, except it doesn’t require the programming step.

This is my first Instructable so all criticisms and comments are welcome.
This will show you how to set up a simple wired web server on your Raspberry Pi, with PHP and MySql.
The Raspberry Pi is a good choice for a webserver that will not recieve too much traffic, such as a testing server, or small intranet, as it doesn;t get too hot (so is nice and quiet), and only uses around 5 Watts of power (costing £3.50 a year where I am if it’s running 24/7)

Arduino has its shields, the Beaglebone Black its capes and up until recently the Raspberry Pi just had expansion boards. The latest B+ version of the Pi comes with more I/Os increasing the pin count to 40 of which 26 are backward compatible with the original connector fitted to the A and B boards. Two of the extra pins ID_SC and ID_SD are data and clock lines to connect to a serial EPROM fitted to the expansion board, sorry HAT. The EEPROM holds the board manufacturer information, GPIO setup and a thing called a ‘device tree’ fragment – basically a description of the attached hardware that allows Linux to automatically load the appropriate driver.

A four-channel remote control built using the EnOcean Pi by Kerry Wong:
In my last couple of blog posts, I did a brief overview of the EnOcean Pi sensor kit from Newark and demonstrated how to compile and run the example code using a Raspberry Pi. In this blog post, I will show a real world example – a four-channel remote control built using the EnOcean Pi in conjunction with the EnOcean pushbutton module.

Actually the first ‘project’ I ever did with a Raspberry Pi was sending a push message to my Iphone. It was 2012, I was lying sick in bed and found a new app on my Iphone called Pushover (what else to do when you’re sick?). With Pushover you can send and receive custom made push messages. On the website I found a simple Python script to send messages. I knew the Rpi was able to run Python code, so here my Rpi adventures started. Within 30 minutes I was able to receive ‘hello world’ on my phone (needless to say I wasn’t lying in bed anymore). Seeing ‘hello world’ on your screen is like the software equivalent of the blinking led, THE coolest feature ever!

When you think Raspberry Pi and camera you probably already know the score; a small camera board that plugs into the Pi’s CSI connector fitted with a fixed-focus wide-angle lens. This versatile setup has been the basis of all sorts of homebrew applications. The SnapPiCam takes the Pi down a different route and converts it into a 5 MP digital camera with interchangeable lens.
Gregory L Holloway is the brains behind this idea, he developed it as an entry into an Instructables competition (which he won) and the response he got encouraged him to launch it on Kickstarter. The design uses the lower spec RPi A without an Ethernet port and with 256 MB of RAM. The camera includes a LiPo battery and DC-DC converter to make it truly portable and different versions allow you to add a rear touchscreen and various interchangeable, magnetic-mount lens ranging from wide-angle to telephoto zoom.

The Director of Hardware at the Raspberry Pi Foundation, James Adams, walks us through the making of the new and improved Model B+ and more…
While he was a chip designer at Broadcom, James Adams ran the design team that created the 3D graphics engine that went on to feature in the Raspberry Pi, arguably the Pi’s strongest asset.
Later he moved to a tech startup called Argon Design that was created by the same man behind the original company that Broadcom bought many years ago for its multimedia technology. The 4th generation of that very chip also features in the Raspberry Pi, so Adams was already well versed with its capabilities long before joining the Foundation in February 2013.
