I’m continuing working with Juan Brito and Danny Macancela from the blog Desafio Ecuador, developing new boards to bring near the technology and programming languages. Our last work is a board to use with the Raspberry Pi and focused to learn Python. The board has the basic elements to start with this language. Also, with the develop of the PCB we remove the wiring, avoiding troubles with connections, inversion polarity…So with this board you only focused in the software develop, because the hardware side will work!
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.

The Gertbot board works as either a stand-alone power controller connected to a computer via a serial link and controlled from Windows or as a plug-in to the Raspberry Pi environment. It has four channels each capable of driving 30 V at 2.5 A and can drive both capacitive and inductive loads. Besides four H-bridges the board also has two open drain N-MOSFETS which can sink 3 A at 30 V. The board is primarily targeted to drive stepper motors, brushed motors and other robotic hardware but it will be just as much at home controlling power in other applications. The outputs have short-circuit and thermal protection.

The web interface allows me to change the settings on my thermostat remotely, such as the set temperature range compressor and fan modes, as well as view any warning messages that may be reported.
It’s not exactly beautiful, but I’m a function-over-fashion person. The Raspberry Pi is in the middle, white power cable running down and a GPIO rainbow ribbon cord heading up to the relay module under the real thermostat.

An open source 3D Printable Raman Spectrometer using a RaspberryPi and easy to find off the shelf components..
An open source 3D Printable Raman Spectrometer that uses a raspberryPi, a couple of arduino compatible ARM boards, a really bright laser and some parts you can grab from eBay, adafruit, sparkFun, Mouser, or wherever…!

The Raspberry Pi Foundation has unveiled the Raspberry Pi A+ – a smaller version of its original Model A – that costs only $20. The Model A+ is significantly smaller than the Model A (65 mm in length versus 86 mm), consumes less power, uses the BCM2835 application processor, and has 256 MB RAM.

Using a Raspberry Pi, a Raspberry Pi camera module, a PIR motion sensor, a USB WiFi adapter, a handful of parts, and a couple of Python programs, you can construct a camera that will automatically snap photos or record short videos when something moves in front of the camera and will automatically upload the photos/videos to Dropbox. This instructable shows how to build a Raspberry Pi Motion Sensitive Camera.

The Raspberry Pi is much more powerful than an Arduino but it has a few limitations of its own. Its I/O is much more limited, it can’t use common Arduino shields, and it needs a regulated 5V power supply via its USB connection. All those limitations are solved with the PiLeven.

A lot of people have been (usually unfavorably) comparing the Edison to single board computers like the Raspberry Pi. Let’s do a little A:B comparison, shall we?
