Raspberry Pi: Essential add-ons for modders and everyday users TechRepublic has covered some pretty nifty hacks for the Raspberry Pi, the $40 credit card-sized Linux computer. But the Pi ships as a bare board, and if you're going to use the Pi to bark commands at a robot or sail an autonomous boat you're going to need to invest in some extras. To help you on your way TechRepublic has rounded-up the ultimate collection of add-ons for the Pi, from boards for controlling robots to keyboards and screens that let you use it on the move. This round-up assumes you already have the basics - the power cables, memory card, basic keyboad and mouse and video leads - you need to get going with the Pi. Note a lot of these accessories have been built by individuals or small teams, so expect a bit of a wait to receive them. Gertboard Before you build a mechanical butler you're going to have to get to grips with the basics of using the Pi to control items in the real world. Gertboard is available through element14.

PY2BBS - Hamradio Page Banho de estanho para placas (a página pode demorar um pouco para carregar, 850Kb de fotos) Proteger placas de circuito impresso contra a corrosão é algo que muitos fazem e utilizam diversas formas, tal como breu dissolvido em thinner, verniz, etc. O breu por exemplo, já é usado a muito tempo e funciona até como fluxo de solda, mas o breu além de ser muito quebradiço é muito grudento, basta manusear a placa um pouco e com o próprio calor e suor dos dedos ele já começa a amolecer e melecar tudo. O verniz já não tem este inconveniente do breu, mas acaba por atrapalhar um pouco a soldagem, pois é preciso uma temperatura acima de 250 graus para derrete-lo e ele deixa sujeira na solda que precisará ser limpa com uma escova de dentes velha Em todos os dois métodos acima, mesmo assim o cobre ainda tende a oxidar com o tempo, ficando com aspecto escuro, isso devido a própria reação com a camada protetora, a própria sujeira que ficou durante a manipulação entre outros fatores. Chega de blablabla.
Citrus Raspberry Pi Evil Mad Scientist Laboratories | Making the world a better place, one Evil Mad Scientist at a time. 8 great Raspberry Pi projects created by kids What do you get when you combine the Raspberry Pi with some inspirational young inventors? Terrific Raspberry Pi project designs, that's what. Fourteen groups of teams from schools, universities and businesses gathered in late March at PA Consulting Group's Cambridge Technology Centre for the awards ceremony of the PA and Raspberry Pi-making competition. The young programmers presented their inventions to a hand-picked judging panel after being given three months to work on their designs, a £25 Raspberry Pi and up to £50 of additional hardware and software. The idea was that the inventions should be beneficial to others – perhaps enabling better healthcare delivery, promoting information or benefiting the environment. The competition was launched in response to a fall in programming skills and was aimed at increasing the numbers of skilled coders, developers and engineers. So without further ado, let's check out some of the projects put together by the teams: 1. This school loves running.
Top 10 Things to Connect to Your Raspberry Pi During my time with the Pi I’ve experimented with various devices and sensors. Here is my Top 10 list of devices to connect to the Raspberry Pi. In most cases they are very cheap and easy to interface and are great building blocks for more complicated future projects. From robot cars to security systems there are plenty of ways of combining these mini-projects into some amazing creations! Ultrasonic Module Ultrasonic Sensor Ultrasonic transducer modules are an easy way to add distance measuring capability to your Pi. Take a look at my “Ultrasonic Distance Measurement Using Python” posts to see how you can connect one to the GPIO header and read it via a simple Python script. PIR Movement Sensor PIR Module Simple “Passive Infra-Red” sensors allow you to detect movement. An example python script can be found on the “Cheap PIR Sensors and the Raspberry Pi” page. Stepper Motor 28BJY-48 Stepper Motor This was one of the first bits of hardware I attempted to control from the GPIO. 20×4 LCD Module
How to Tether Your Raspberry Pi with your iPhone 5 | DaveConroy.com Posted by dconroy on Jul 3, 2013 in How To's | 26 comments | 51,826 views If you have been reading my blog lately you know that I have done a lot of projects involving Raspberry Pi‘s, the $35 dollar credit card sized Linux computer. Because of its small size, I recently started of thinking of projects that would allow me to be mobile with the Pi. That led me to this post. There are plenty of resources online about tethering the iPhone 5 with the graphical interface, but I wanted to be able ‘hotswap’ my Raspberry Pi’s Internet connection without command line, and without the graphical interface. I was able to get this working last night using Raspian (a free operating system based on Debian optimized for the Raspberry Pi hardware) and a few scripts. Prerequisites Make sure your iPhone is disconnected and proceed to install the following iPhone and file system utilities. After these are installed, and with your iPhone still not plugged in, lets take a look at our available interfaces. #!
Alamode connects Arduino shield to the Raspberry Pi #piday #raspberrypi @Raspberry_Pi December 28, 2012 AT 8:00 am Here’s an updated tutorial for using an Alamode with the Raspberry Pi from Drew Fustini at Element14: I finally got a got a chance a couple weeks ago to experiment with my Alamode from Wyolum. It’s an Arduino-compatible board with an ATMega328 that sits on top of the Raspberry Pi. It has has headers for Arduino shields and also features a real-time clock and microSD card reader:The setup for the Alamode on the Pi is pretty simple when following Wyolum’s Getting started guide.
