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. You can learn more about this project at hackaday.io/project/5083

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!

Raspberry Pi gadget lights up when International Space Station is nearby with Live HD video from the ISS now with Wearable LEDs
The original version of the ISS-Above was funded through a successful Kickstarter nearly 1 year ago. Since then more than 800 ISS-Above’s have been installed worldwide.
At the heart of the ISS-Above is the lovable and successful single board computer called a Raspberry Pi. Over 5 million of these little computers have been sold worldwide.
The ISS-Above functionality has been drastically improved since the first Kickstarter with some truly remarkable new features – including the display of live HD video views of the earth directly from cameras on the International Space Station.

Have you ever wanted to wirelessly control power outlets from your phone? You could buy a Belkin WeMo Switch for over $40 for 1 outlet or build your own with 5 outlets for under $35 if you already own a Raspberry Pi. Hopefully this post will guide you in the right direction.

Raspberry Pi in a form of so called “compute” module provides all good features of this well-known microcomputer and lets you choose which peripherals to use.
Idea of the Raspberry (RPI) compute module is in a fact, that there are applications, where easy applicability of this microcomputer might be advantageous, but its dimensions (including connectors in original version) don´t allow it to you. For these cases, the new Raspberry compute module is suitable, what´s literally only the “computing module” itself, in a substantially more flexible form factor. Raspberry Compute gives allows designer to freely use only required peripherals, at minimal space requirements (dimensions only 67.6x30mm). The size comparison is illustrated in attached picture. The module can be easily connected to a target application through a usual DDR2 SODIMM connector, for example Attend 121A-52A00.
The Compute module contains the same „guts“ as Raspberry Pi (BCM2835 processor and 512MB RAM) as well as 4GB eMMC Flash memory (equivalent to an SD card in RPI). With this module. it´s possible to deploy full functionality of the BCM2835 chip and even more GPIO pins and interfaces than in a standard version. Detailed information will provide you the RPI Compute module datasheet. Upon order, there´s available the development kit RPI COMPUTE DEV KIT (containing the module, IO board, cables for camera and display, 5V power source and a USB cable).

The Raspberry Pi 2 – Model B – ARMv7 with 1G RAM is here!
The Raspberry Pi 2 delivers 6 times the processing capacity of previous models. This second generation Raspberry Pi has an upgraded Broadcom BCM2836 processor, which is a powerful ARM Cortex-A7 based quad-core processor that runs at 900MHz. The board also features an increase in memory capacity to 1Gbyte.
Broadcom BCM2836 SoC
Quad-core ARM Cortex-A7
Dual Core VideoCore IV® Multimedia Co-Processor
Provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode
Capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure
Boots from Micro SD card, running a version of the Linux operating system 85 x 56 x 17mm and is possible to run Windows 10
Micro USB socket 5V, 2A

This will help to see the state of roads, in live, just need to load your favorite (urban or not) traffic map.
To use the touch screen, we run under a Raspbian distribution, you can download the image file here already configured to work with the XPT2046 LCD Control (most common 3.2 TFT found on ebay) . Extract the image file on a 2Gb mini SD Card, and run the setup config.

New 3,2“ and 3,5“ displays from company 4D Systems intended for Raspberry Pi are able to make a complete standalone system from this microcomputer.
Graphic output is always beneficial, enabling to use embedded microcomputer as a user interface (HMI) or at least to display various variables etc. There are many ways to reach it, but probably the most desirable solution would be to connect a display and nothing to solve.
New graphic modules 4DPi-32 and 4DPi-35 belong right to this group of ideal solutions, as they´re directly designed for Raspberry Pi (A,B, B+) – electrically and mechanically, while the I/O connector remains still available.
Simplicity of usage is empowered by a fact, that they don´t require (external) power supply, as they´re powered from the computer itself. Communication is done through a high speed 48 MHz SPI connection. Speed of a built-in processor enables displaying of pictures and videos with up 25 fps speed (even more if images can be compressed). Resistive touch panel enables operation of the whole system without a mouse.
As for the size, there´s only a small difference between 4DPi-32 a 4DPi-35 modules – the biggest difference is in resolution 480 x 320 px (4DPI-35) vs. 320×240 px (4Dpi-32). Both displays display GUI (primary) output of the Raspberry Pi – the same as if we had a monitor connected.
