So I turn to my growing PLN, Personal Learning Network. Thanks to my colleagues at the University of Regina, I connected with Alec Couros. Alec is a leading expert in the world of connected and open learning and using social media in education. Currently, he is leading a MOOC, Massive Open Online Course, etmooc. I have had many online conversations, both text and audio, and a few video conferences in Google Hangout. (Yes, it does work on my Qiniq account). My PLN has increased 100fold along with my enthusiasm for connecting with people digitally. I may not be able to have a great conversation around the coffee machine but I can have those stimulating conversations at my desk or on my big comfy couchAll of this has prompted me to set up a Google Community in Google+, Connected Arctic Educators.pandora bracelets uk Here are a couple of screencast tutorials from one of my new etmooc circles, Aaron Mueller. Watching these helped me get started in Google+ and after using it now for a couple of weeks I am convinced it’s a great toolLinda Pemik is the Senior Academic Officer for Nunavut Arctic College, Nunavut’s only post secondary educational institution, with campus and community learning centres in all 25 of the territory’s communities.

Connecting an Ipod or Iphone to my 2003 Prius

This is my first Instructable, and describes how I connected my Ipod to my 2003 Prius. The information and options I found should help others add MP3 sound to any car. I’ll present several solutions, along with pros and cons.

When I first got my Ipod, I used a cheap cassette adapter to listen to podcasts in my car. The sound quality was so so, and it occasionally malfunctioned. Eventually, the car’s cassette player stopped working entirely, so I was motivated to look for a better solution.

First, figure out where you’ll input the sound. If your (recent model) car has AUX or mp3 inputs built in, you’re done, just use them. Otherwise, your options include tapping into a cable connecting one part of your sound system to another, or tapping into the head unit itself. The most popular option is to trick the car’s audio system into accepting mp3 player input instead of input from the CD player this is the option I’ll describe in detail. Search your car’s audio model number on the internet for information about your system, and figure out where (ie which pins or wires) the input goes.

Is sound quality and volume important? Just sound, or should the car charge your Ipod, too? Do you want a system that works with any MP3 input, or just your Ipod? Do you mind adding switches on the dashboard? Do you mind a cord sticking out of your dashboard? Do you want to continue using all the sound options on the car, or will you sacrifice one of them? Do you want to do this cheaply, or will you spend more to get a slicker solution?

Which kind of input? The mini stereo connector on the Ipod (where you plug in the earphones) is in the R/L/Ground form. An older or simpler car audio system may accept input in the R/L/Ground form, but newer systems more likely use R+/R /L+/L .

(Briefly, the R+ and R are inverse to each other the car audio system uses the difference between the two signals. This yields more volume and less distortion than comparing R to ground.)

The CD cable in my car includes wires R+, L+, R , L , signal ground and electrical ground. Since the Ipod only has R, L and ground, the question is how to connect them for the best sound quality and volume. Connecting the Ipod ground to the audio system’s R and L cables sounds good when the Ipod’s playing, but you sacrifice quality and volume of sound from the CD player if you leave R and L connected together.

So if you’re choosing a « piggyback » approach (leaving the connection in place all the time), connect the Ipod ground to the cable’s signal ground. If you’re using a switched approach, connect the Ipod’s ground to R and L . (Don’t connect the Ipod audio ground to the car’s electrical ground depending on the car audio system this could fry your speakers or your Ipod.).
