Okay, there are too many open source home automations out there but whenever I tried to look into making any of these I ended up with a bitter taste because of one or a few of the following reasons:
The software part was open but the hardware was based on boards either too complicated to produce myself economically or simply proprietary that I could only buy ready
The sensors/parts were too expensive
It was too ugly for my living room

After a successful funding campaign on Kickstarter earlier this year the low-cost RasPiO Duino board is now in production and available to purchase. The RasPiO Duino is a small development board with similar functionality to an Arduino Uno. Once it is plugged onto a Raspberry Pi the system forms a complete low-cost Arduino development environment allowing programs to be developed and loaded to the RasPiO Duino. The board can then be unplugged to function independently.
It can also be used to operate interactively with the RPi. The RPi’s GPIO ports are broken out on the board as well. A 72-point prototyping area is provided with GND, 3V3 and 5V rails to facilitate the addition of custom circuitry.

I’m so excited about this new project! A truly compact and portable Raspberry Pi Camera and it’s easy as anything to build!
I first thought about building a Raspberry Pi Camera after seeing the SnapPiCam instructable guide. This is a clever little project, which uses a LiPo battery to power a Raspberry Pi model A. But it got me thinking could I do something even more compact which is even simpler to build?
The real challenge is powering this little baby. Where the SnapPiCam is using a separate battery, converter and charging unit I’ve used the PiJuice. It’s basically an all in one battery module for the Raspberry Pi and it’s an ideal integrated power solution for a DIY Compact Camera.
I’ve also decided to use the Raspberry Pi a+ as it’s the cheapest and smallest available Raspberry Pi so it’ll fit nicely with PiJuice and make this camera supper compact!

Wireless, Credit-Card sized, Android + Linux + Arduino™, Embedded Sensors, starting from $49. What else?
UDOO Neo embodies a new concept: a single board computer suitable for the Post-PC era:
- Like a Raspberry Pi, you can program it in any language and run a full Linux environment with graphic interfaces.
- You get all the simplicity of an Arduino-compatible board, thanks to the Cortex-M4 and the Arduino UNO pinout layout, with the possibility of adding most Arduino™ shields, actuators and sensors, both analog and digital.
- An incredible, smoothly-running Android 4.4.3, it gives you the possibility to build new Android-based smart devices.
- You get a wireless module: Wi-Fi 802.11 b/g/n + BT 4.0 (Classic Bluetooth and Bluetooth Low Energy), because we hate cables.
- 9-axis motion sensors are embedded, to build your perfect drone/robot/3D printers/whatever or create new kinds of interactions with the real world.
- Open-source hardware: because we love to let you hack things or create new devices from scratch!
- Starting from $49!

Startup Percheron Electronics Ltd is looking to fund their rather neat E-Paper display HAT for the Raspberry Pi. Unlike some similar display solutions for the Pi this E-ink HAT attaches without any long ribbon cables. An advantage of this type of display (similar to those used on the Kindle) is that the image persists on the screen when power is removed so they use less power than a TFT display but the E-Paper technology does not support fast moving images.
The PCB is compliant with the Raspberry Pi Foundation’s HAT specification, including device tree configuration of the required GPIO pins by the HAT EEPROM. The board is able to drive a 2.7″ 264 x 176 pixel E-Paper display panel and is also suitable for the 1.44″ and 2″ display panels from the same manufacturer.
The board also features a DS3231 real time clock (RTC) IC with a CR1220 lithium coin cell for battery backup when the Pi is powered down. The DS3231 is accurate to 5 parts per million, or within 3 minutes per year. The RTC can generate an interrupt/alarm signal and also a 32 KHz clock signal which can be connected through to GPIO pins by solder pad links, if required.

This tutorial brings you from start to finish in constructing your very own smartphone. You will start by 3D printing a case, then soldering printed circuit boards together, assembly, and finally installing a mobile OS onto your phone and using Python to make it yours.

Back in late February I saw this post on the Raspberry Pi site.
They had created Raspberry Pi Weather Stations for Schools. I totally wanted one! But at that time (and I believe still as of writing this) they are not publicly available (you need to be in a select group of testers). Well, I wanted on and I didn’t feel like shelling out hundreds of dollars for an existing 3rd party system.
So, like a good Instructable user, I decided to make my own!!!

Spurred on by the completion of my two previous projects, the Compact Camera and Portable Games Console, I wanted to find a new challenge. The natural progression was an outdoor remote system…
I wanted to build a Raspberry Pi weather station that was able to sustain itself off grid and send me the results through a wireless connection, from anywhere! This project really has had its challenges, but luckily powering the Raspberry Pi is one of the main challenges that has been made easy by using the PiJuice as a power supply with it’s added solar support.

PiJuice is the ultimate module for all portable Raspberry Pi projects. Includes many fun maker projects and a solar power version too!
As one of the smallest systems around there’s so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. With PiJuice we want to provide not only the best portable hardware/software solution, but also a set of inspiring and affordable guided projects for fun, learning, and breaking out the Pi into the real world.
For the past year we’ve toiled and sweated over the technical minutiae of PiJuice so you don’t have to.
- Onboard 1400 mAh “off the shelf” Lipo battery (with support for larger Lipo Battery up to 5000 mAH+) to last up to 24 hrs + in constant use!
- Full UPS (Uninterrupted Power Supply) solution.
- Integrated RTC (Real Time Clock)
- On board intelligent on/off switch
- Low power deep-sleep state with wake on interrupt/calendar event
- Programmable multi-colored RGB led
- Full power management API available to Raspberry Pi OS with auto shutdown capability when running low on batteries
- Raspberry Pi HAT compatible layout, with on board EEPROM for easy plug and play operation
- Low profile design, to fit inside lots of existing Raspberry Pi cases!
