Electronic engineering and amateur probably aren’t things you usually hear together, or want to considering the dangerous implications of DIY re-wiring. But while it might not be a good idea to start pulling the circuits out of your electronic devices there are some ways that even an absolute beginner can have fun with electronics. Here are a few examples of some top projects to get you started – remember to look them up on the web afterwards for in-depth instructions and kits to buy.
If you want to start with super basic electronic device manufacture, with an end result that’s really also useful in lots of situations, why not learn how to make some speakers? You might be used to seeing speaker systems with a fair amount of zeroes in their price tag, but for this little gadget you’re talking a few pence. Take an old pair of headphones – like the ones you got with your i-pod and don’t use anymore – and cut the ear buds off so as to leave an exposed wire. Cut some small holes in a pair of paper plates and stick the wires through, then tape that wire to a smooth, stretched piece of tin foil so the wire is touching the foil. Secure the foil to the paper plates, keeping it nice and tight – voila: plug in for a pair of speakers.

In a world where cultures are judged by the art they leave behind it is just fine to create art for no other reason than to create art. In doing so we are saying something about our culture. We are saying we value creativity, exploration and diversity. These are important concepts culturally and they are of course enduring. Does the same ring true for innovation?
We have never lived in a time with more innovation. It is true that there have been periods when innovation delivered more seemingly important things – the wheel for example… Or more amazing things – Man on the moon and all that… Or more impressive things – The pyramids but when you look at innovation by volume – now is the time.
We are seeing rapidly iterating innovations from companies who are fighting desperately to keep ahead of the innovation curve. As soon as a company ceases to innovate they fall by the wayside and are replaced by leaner faster and more innovative organisations. Continue Reading →
Democracy in essence requires that all members of the society have a say in the decisions that effect their lives. This means that everyone needs to decide what it is they want and then elect those who have the most aligned agenda.
To achieve true democracy people need information so that they can make an informed decision about who they would like to govern them. Sadly our system does not allow for this. Lobby groups often wield fistfuls of dollars to influence politicians and the public that there agenda is not just the right agenda but the only agenda. They often represent minorities yet somehow they have the loudest voice. This system stifles democracy.

Every year I have a medical check-up. I get the works done. Blood tests, weight checked, blood pressure
and one or two other things that I’ll keep between myself and my doctor. It’s my way of keeping score and
managing any physical deterioration. I don’t mind growing old – I just want to delay it as long as possible.
Inevitably I’ll ask my doctor how I’m tracking. Inevitably he’ll respond with “you’ll live until you’re 90 at least.”
It’s a game we play. I enjoy it. I think he does too. This time, however, he was in a thoughtful mood and he
followed up with “you realise, of course, that you have less than half of your life left to live. Knowing that,
what would you do today if you knew you could not fail?” It is a very powerful question that got me thinking.

Hi Dan, you have founded Nerdi, prior to this you were in a role as Clinical Educator with the Ambulance Service of NSW. Why the change, the desire to create and invent your own business?
I’ve always had a really strong drive to make a difference. It’s why I became a Paramedic. As a Paramedic you can make a profound difference to a small number of people each week. In the beginning I was buzzing all the time. It’s so rewarding to help people in that way
As my skills improved I realised there was always more to know. The better Paramedic education was, the greater impact Paramedics could have. I became a Clinical Educator as I knew I could have a much bigger impact in the community if I could lift the quality of Paramedic education. Instead of affecting a limited number of people each week I could indirectly affect hundreds or thousands through my students by improving their clinical knowledge and thus the treatment they administered to their patients.

Have you ever thought about what happens to your brain when you learn?
From a physiological perspective it’s all about the neurons in your brain. Connections form as you learn and knowledge is born. This process becomes more difficult as you get older however people tend to be more focused learners as they get older so the motivational difference can out-way the physiological limitations.

The Indian government has just released $35 tablets to 100 students as a trial…
This is part of the government’s tech strategy designed to create a cohort of tech savvy citizens. Consider what a global force India will be when the entire next generation will understand and leverage devices like this.
One enormous advantage of this sort of device is that they are putting the potential for modern education in the hands of the masses. The strategy is in place to familiarize a generation with tech however the real gains will be made in the increased access the students will have to excellent international and local educational content.
This first device is no doubt slow and has stripped down features however do not underestimate the power of millions of these things in the hands of the Indian student. A very exciting prospect indeed.
