Now for the second part in a series of movies explaining how to make your own AR app using Live Photo’s. By the end of this guide you will have an app that will detect the photo and start playing the animated movie over the top. Don’t forget to grab your resources from the first guide and also print your photos.
This is the first part in a series of movies explaining how to create your own AR app using Live Photo’s . Have fun following along and I’d love to hear how you go.

At the end of last year I spent some time learning how to create an iOS app using the Augmented Reality tools available in Xcode. Below is a tweet I posted at the time to refresh your memory (well, for those who follow me)

What I have learned from this experience is that AR development is really not too complicated in iOS, many of the intelligent work is done behind the scenes. So to just place an object into an AR scene you really just need to know where in the space around you want to add it and then drop it in. The default template for an iOS AR app already has a “Jet Plane” object and without changing a line of code you get a working app. Here is what it looks like:
From this point all you need to do is define points in 3D space and add text, images and movies.
The example from the Tweet I made follows a process where the app “looks” for objects that match the size of an A4 page with the same contents of one of the images. It then attaches a node of the same dimensions over the top and then plays a movie which matches the photo inside the node. I later added text that sits above the object and moves with it.
Once I made the basic app I saw the possibilities to me of how this could be used at school. I believe this a great template for a AR tour of a school. Meeting the requirements of being a real world problem and solving a problem that affects the community, students could easily come up with their own version of using the app.
Mathematically speaking I also appreciate the complexities in understanding how to place the objects inside the AR space. The technology understands distances and angles perfectly so it become a great activity in reinforcing these concepts.
So over the coming week or so I will be releasing 5 movies that explain the process of creating the App. The best part is that the app works well after covering 2 of them, so it is quick at getting some buy in. The final 3 movies go through the process of adding some polish.
I look forward to seeing other educators and students having a go and seeing what they come up with.

So since my last post where I discussed my recommendations for a good podcasting microphone I have received a couple of orders from Amazon.
First is a shock mount which is designed to remove some of the vibrations that may occur from moving the microphone to bumping the desk.
This is the one I grabbed:
The only problem was that I didn’t check the sizes so I needed to 3D print a part so that the microphone sat comfortably.
I also purchased a foam microphone wind protector to help soften the noise of the microphone.
This is the one I grabbed:
Together they all look pretty cool:
For all intensive purposes do not record audio through the microphone of your laptop, these microphones pick up far to much background noise and never provide any kind of reasonable quality.
A starting point is to just use the microphone attached to Apple AirPods – which will provide a clearer recording just by the fact that it will sit closer to your mouth. It also works well while on the move.
In my experience the “feel” of a podcast changes dramatically based upon the quality of the recorded audio. Some of the clear “low quality” sounding podcast generally arise when the presenters are located in the same location sharing one microphone.
So how do you choose a good microphone that has a reasonable price? Well you could head to this blog post by Marco Arment of Tumblr, Instapaper and Overcast fame.
An amazing value for the money: it sounds great for the price, and pretty decent at any price, as long as you speak up very closely to it. With USB and XLR outputs and a built-in headphone jack for USB mode, I don’t know of a cheaper or simpler all-in-one solution to recommend. Compared to other inexpensive USB mics aimed at beginners, which are usually large-diaphragm condensers, the dynamic ATR-2100 picks up far less room echo and background noise. But you have to speak up closely to it — get more than about two inches from it, and it gets very bad, very quickly.
This microphone is fantastic and provides great value for money. Tracking one of these down in Australia is its biggest down sides. I managed to grab one from my local PLE computers for $99.
So why this microphone – other than price?
Connecting to a laptop or even iPad could not be easier.
Flexible enough to connect to any professional audio equipment and cabling.
2.5mm Headphone Jack
Plugging your headphones directly into the microphone enables the ability to listen to exactly what the microphone is picking up. This actually makes a huge difference while recording.
A small stand
Easy table top setup.
Like what Marco did in his review, below I have included some example recordings I made using the internal microphones from an iPad Pro 12.9 and a MacBook Pro with also recordings made on both devices with the AT2100-USB Microphone.

One of the many ways I like to pass time while running or driving is by listening to Podcasts. They cover so many topics, themes and styles that really there is an endless amount of content available. I like to listen to podcasts covering technology, education, science and tv shows. At the end of this post I’ll link to some of my favourites that I could not live without.
Over some of the next few posts I will go through the setup that I have been putting together to record, edit and publish a podcast so that people can subscribe and listen. I will try to cover my experiences and choices that I have made – like keeping costs to a minimum.
I would like to point out a couple of resources that I recommend – and that I have used to help in my decisions.
