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.

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.

These novelties are already our stable stock item. Detailed information will provide you the 4DPi-32 and 4DPi-35 datasheets.

gertbot_500x406

by elektor.com:

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.

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.
