Students teaching students IT SPRINGBORO – Students preparing students for future careers was at the heart of a week long effort to promote information technology in Springboro Community City Schools. Springboro High School students enrolled in IT and digital media programs – satellite courses of the Warren County Career Center – recently taught their junior high and high school peers about computer science. “The purpose of this week is to bring awareness to the computer science field in the way of education and job opportunities,” said instructor Jenifer Conard. “Allowing our own students to teach is more effective as they are able to relate to their own peers.” According to data from the National Science Foundation, fewer than 2.4 percent of students earn a degree in computer science – and yet the need for computing skills and the demand for technical jobs is increasing. Data also shows that computing jobs are growing at a 3.6 times the rate of other fields in Ohio.

100 Ways to Make Maker Faire Year-Round Maker Faire is happening all around the world and all through the year. For those of us who plan our year around Maker Faire Bay Area, however, we’re two weeks into 52 weeks of Maker Faire withdrawal. For ourselves and all of you, we’ve put together a small poster with 100 ways to make it through these 365 days, and to keep on making year-round. These 100 things will keep you making until your next trip to any Maker Faire near you no matter where you live. Here’s a starter list of fun projects you can do to make every day a Maker day. Presents Wolfson Audio Card for Raspb Overview Wolfson and element14 introduce an audio card to offer Raspberry Pi users the ability to capture audio alongside their camera, and experiment with stereo digital capture and playback. Raspberry Pi, whilst doing a fantastic job of being a small and powerful computer, does this by a number of compromises. One of those is the limitations on its audio capabilities. Out of the box, Raspberry Pi provides good quality audio across the HDMI link, lower quality stereo audio by way of its 3.5 mm stereo jack, but no capability to connect microphones or other external audio sources, such as attaching directly to loudspeakers.

How To Tune In Pirate Radio Broadcasts on Shortwave This article originally appeared in the February 2014 issue of The Spectrum Monitor Magazine. QSL from Radio Gallifrey Intergalactic Even as many legacy international broadcasters are abandoning the shortwave bands, shortwave remains active and vibrant in another quadrant: namely, on shortwave pirate radio. Over the past few years, I’ve found that one of my favorite listening activities has become searching for unique pirate radio stations, and readers of my blog appear to have followed suit. Among the most popular queries made by readers is, “How can I find and hear pirate radio stations?” To help answer this question, I’m writing this primer.

SSH into Raspberry Pi using Putty This post is for those who don’t have a separate screen for Pi or a TV with HDMI or have a screen with DVI port. To tackle this issue we have two options. Use a Converter ie. Using Gaming Principles to Engage Students Game designers understand how to make games memorable and "sticky" in the sense that, even when you aren't playing the game, you're still thinking about solving its problems and puzzles. As teachers, how might we make our projects and content as sticky as games? How can we engage kids in thoughtful learning even after they leave the classroom? Here are game designers' top five secrets and some tips on using these same game dynamics to make learning in your classroom as addictive as gaming. 1. The Story Dynamic: Wrap Them Up in the Story

Makers WNET is a proud partner of the Maker Party, an initiative hosted by Mozilla, the MacArthur Foundation, and the National Writing Project in which people around the world meet up, learn to make things, and share what they've made online. This collection is designed to support the Maker Party by providing a one-stop shop of STEM and digital making resources that focus on the problem, technology, or process behind object creation. Teachers can use the collection, which is categorized into design, how to (DIY), arts and crafts, robotics, and engineering subtopics, in conjunction with hands-on activities to further this initiative.

Pi MusicBox Make your Raspberry Pi stream! Welcome to the Swiss Army Knife of streaming music using the Raspberry Pi. With Pi MusicBox, you can create a cheap (Sonos-like) standalone streaming music player for Spotify, Google Music, SoundCloud, Webradio, Podcasts and other music from the cloud. Or from your own collection from a device in your network.

JASPERadio, The Radio to rule them all Once upon a time, it was now, and I attended a cool PIC class, taught by a dude who started and owns an automation company and decided to pass his programming and design knowledge on. When we got a bit bored with messing with our testing boards with buttons and a temperature probe and 7-segment displays, the idea of building a radio from the ground up sort of happened. The plan now is that we'll design the important stuff and then each of us will get on coding, enclosure building and stuff like that.

raspberry_pi:diy [ PIRATEBOX] Install PirateBox The following instructions are for installing PirateBox on a Raspberry Pi. Stuff You'll Need Installation 1. UK schools to make space apps with interstellar Raspberry Pi computers UK Space Agency astronaut Tim Peake will take two Raspberry Pi computers on his next space mission, in the hope that UK pupils will create their own app or experiment that can be deployed on the International Space Station. Peake will fly two “Astro Pi” maker-boards, which have been kitted with sensors, to the space station when he begins his six-month mission. Primary and secondary school children will compete to develop an idea for an application, which if successful, will be developed with the help of the Astro Pi, CGI and Raspberry Pi Foundation, who will code their idea.

3D Printed GoPro Cannon Cam The original Cannon Cam shell was one of the first custom 3D projects I made when I started working at Make Labs. Due to the design constraints of the Thing-O-Matic 3D printer, the idea was doomed from the start, but I printed it out anyway. (It looked cool and I was excited about 3D printing.) It sat on my workbench for 3 years, until my editor noticed it during a brainstorm session for new 3D-printed projects. Note names, MIDI numbers and frequencies Note names, MIDI numbers and frequencies are related here in tables and via an application that converts them. The musical interval between two notes depends on the ratio of their frequencies. See Frequency and Pitch for more details and an introduction to frequency and pitch. An octave is a ratio of 2:1 and, in equal temperament, an octave comprises 12 equal semitones. Each semitone therefore has a ratio of 21/12 (approximately 1.059). By convention, A4 is often set at 440 Hz.

Forums - View topic - WiFi Walkie Talkie Recommendations? Back Story: My wife and I have some friends who moved across the country not too long ago. We've known them for a long time, and our kids are friends as well. I would like to investigate building a pair (or perhaps a trio) of WiFi Walkie Talkies.
