Adafruit Raspberry Pi Educational Linux Distro This is our second distro, Occidentalis v0.2. Rubus occidentalis is the black raspberry. It is derived from Raspbian Wheezy August 16 2012 We have made a few key changes to make it more hardware-hacker friendly! Version 0.2 updates (new!) Every Child a Maker: How the government and private sector can turn kids on to science and engineering through Making Photograph by Saul Loeb/Getty Images. Earlier this year at the White House Science Fair, President Obama met Joey Hudy, a 14-year-old who developed the “extreme marshmallow cannon” capable of projecting a marshmallow 175 feet. Joey handed the president one of his business cards, which stated simply, “Don’t Be Bored, Make Something.” Joey is a self-described “Maker,” part of a growing community of young people and adults who are designing and building things on their own time.

INA219 Current Sensor Breakout The INA219B breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can use this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision. Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. Since the voltage drop across the resistor is proportional to the current draw, this means that the ground reference will change with varying current. Having a shifting ground reference can cause problems for many circuits.

National Obesity Forum - State of the Nation's Waistline - Obesity in the UK: Analysis and expectations The purpose of the State of the Nation’s Waistline report is to audit the state of obesity in the UK, to identify what initiatives and policy exists, and to assess their effectiveness in tackling obesity and weight management issues. Obesity and weight management are a direct cause of many health problems and are already placing enormous demands on the NHS at a time when health resources are stretched like never before. The current situation is unsustainable. The report makes recommendations as to what we must do in order to address one of the great public health and societal problems of our time. The report has been released to coincide with the launch of National Obesity Awareness Week, an opportunity to engage with the public and raise awareness of obesity and weight management – but more importantly to discuss and highlight how these issues can be addressed at national, business, societal and individual levels.

Raspberry Pi Raspberry Pi 7” Touchscreen Display The Touchscreen Display gives users the ability to create all-in-one, integrated projects such as tablets, infotainment systems and embedded projects. Buy Now Learn More INSTALL - webiopi - Raspberry Pi Internet of Things framework - Google Project Hosting WebIOPi is developed and tested on Raspbian. You only need Python, either 2.7 or 3.2. Download, then extract and install WebIOPi. The setup script will automatically download and install required dependencies using apt-get. You may have to manually install GCC and Python development headers if you are not using Raspbian. Update note: Stop your existing WebIOPi service, then process with the setup.

Can DIY Movement Fix a Crisis in U.S. Science Education? JEFFREY BROWN: Next, making the stuff of science and making learning about it more fun for kids. NewsHour science correspondent Miles O’Brien shows us how. MILES O’BRIEN: At first blush, it all seems so typically suburban. But, if you want to keep up these Jones, you best stock up on propane, power tools, and polymers. They are the DeRoses of San Rafael, Calif., dad Tony, and his sons, 17-year-old Sam and 12-year-old Joseph. They are superstars of a vibrant, growing subculture called the maker movement, which celebrates, venerates the art of designing and building really cool things. Can you move over? The 74HC595 8 bit shift register OK, so say you have this crazy cool idea where you need to control a ton of LEDs (I know, I know… LEDs). You looked at the multiplexer article, and that was great, but this idea is so cool, you need individual control of each LED, and turning them on one at a time just won’t do. Well again, we are here to help, and now it’s time to introduce you to the Shift Register.
