DS18B20 Temperature Sensing @ The Adafruit Learning System. The Occidentalis Linux distribution for Raspberry Pi (and Raspbian as of Dec 2012) includes support for the DS18B20 1-wire temperature sensor. Raspberry Pi: Creating a Camera - Safari Blog. A guest post by Les Pounder, a Freelance IT Consultant and Trainer from the UK who is a regular contributor to many Linux magazines and podcasts.

You can find out more about him at about.me/lespounder. For just over a year, the Raspberry Pi has dominated the attention of makers and the media as well. For many, the device has laid unused on a dusty shelf. Raspberry Pi and PiFace. 2. Second, install the PiFace Digital libraries and change the permissions of the SPI interface. Luckily, running this command will automate the entire process. sudo apt-get update. Running A Python Script At Boot Using Cron. There maybe times when you want to run a Python script when your Raspberry Pi boots up.

Running A Python Script At Boot Using Cron

There are a number of different techniques to do this but I prefer the method that uses “cron”. Cron is a job scheduler that allows the system to perform tasks at defined times or intervals. It is a very powerful tool and useful in lots of situations. You can use it to run commands or in this case, a Python script. The Raspberry Pi Hobbyist: Running From an External Hard Drive. Breadboarding for beginners for the #RaspberryPi. The guys over at MakerSpaceUK have written an excellent little tutorial that will help you get started with creating your first circuit using a breadboard and some LEDs.

Breadboarding for beginners for the #RaspberryPi

There’s even a kit you can buy through Farnell for less than £5. It’s a nice little project that will have you programming, in Python, a traffic light sequence. The Raspberry Pi Guy. NEW Raspberry Pi Zero – $5 Computer!

The Raspberry Pi Guy

Almost 4 years on from initial launch and 7 million boards later, the latest slice of Pi has just been served. Meet the Raspberry Pi Zero. Cheat Sheet - USB drives. Create your own J.A.R.V.I.S. with Jasper and the #RaspberryPi. If you’ve ever wanted to replicate Tony Stark’s J.A.R.V.I.S., you can be well on your way with this project.

Create your own J.A.R.V.I.S. with Jasper and the #RaspberryPi

Shubhro Saha and Charlie Marsh from Princeton University have developed an always-on voice-recognition-and-response system called Jasper. It recognises it’s own name and commands you give to it verbally and then speaks aloud a response. They’ve created a lovely website for it at where you can find out how to build your own Jasper and download the code. There is even documentation for how you can extend Jasper for your own uses – it’s all written in Python so it would be pretty simple to modify. Find out more about Jasper here or watch their video below:

Mount a USB flash drive on your #RaspberryPi. Send email from Python. Ohm's Law. Next Page: Power and EnergyAlso See: Voltage and Current | Resistance | Resistors To make a current flow through a resistance there must be a voltage across that resistance.

Ohm's Law

Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R). Science & Nature - Robots - Techlab. 2013-09-19-raspberry-pi-lego-robot-part1. Introducing Pisaac, my Raspberry Pi robot : Pieces of Pi. Hello everyone, this is Pisaac.

Introducing Pisaac, my Raspberry Pi robot : Pieces of Pi

Pisaac is built from a Raspberry Pi, a PiFace, a DRV8833 motor controller on a breakout board, a Dagu “Magician” robot chassis which I got from Amazon (also available from many other retailers!) , an Edimax Wifi dongle, a mobile backup battery pack and a Raspberry Pi Camera module. Why am I building Pisaac? Just for my own entertainment really! HobbyTronics. Raspberry Pi – Initio Robot by 4tronix! In this video we will take a look at the Initio Robot from 4tronix.

Raspberry Pi – Initio Robot by 4tronix!

I explain what the Initio is, what the capabilities of the Initio are and demonstrate a few of its many functions. Robots are great fun and, in my opinion, one of the best ways to learn about programming and electronics – the Initio is the perfect beginners robot. It encompasses a huge range of components; from IR distance sensors to servo pan and tilt systems! The Initio is made and sold by 4tronix, an excellent quality retailer for all of your electronic component needs! Line following self-balancing robot controlled by a #RaspberryPi. Electronics and Robotics. How to Build a Robot Tutorials - Society of Robots. Add video streaming from your #RaspberryPi robot to a web device. This article from Linux User & Developer builds upon their previous work to do with building a robot with a Pi.

Add video streaming from your #RaspberryPi robot to a web device

To start with, the article takes you through using mpeg-streamer very nicely to stream video from your Pi Cam. It then moves on to installing Apache and building a web interface for remote control. Read it here. Pi Robot. This is a very simple robot based on a Raspberry Pi with a L293D motor controlles connected to two motors and wheels. Running on the Pi I have a python script which checks the current message on livebots and moves the motors accordingly. You can control it LIVE at: Here are some photos: Daddy's Robot Car: DRC Mark 1. Well.... It may not be pretty... but it's fun to do... Trying to use the Raspberry Pi and its camera to navigate the room full of toddlers toys...

The ultrasonic setup is not being used - navigation is solely down to the vision... A fairly simple algorithm - what's flooring?

Mikronauts.com » Elf – 2WD Pi Robot. Meet Elf – my 2WD gear motor robot based on RoboPi and Raspberry Pi !

Last Updated: October 22, 2014 – added wiring photos and sample code After receiving my prototype RoboPi printed circuit boards, I did my initial testing with my SPRITE robot… and it worked great, however SPRITE uses continuous rotation servos for locomotion, which is great for small, light robots, but not sufficient for larger, heavier bots, nor for testing various motor driver boards with RoboPi. The Magician 2WD chassis is inexpensive, and readily available – and I have quite a few in stock – so I thought it would be a great platform for testing low power motor controllers, and building an inexpensive RoboPi + Raspberry Pi based robot – thus Elf was born.
