The Art of Engineering

On 29 June 2009 my wife and I became parents to Grace Drennan. It is a great privilege, honour and responsibility to be a part of this amazing little life.


Life was turned upside down and changed forever. The last two years have been an intense period of learning and self-discovery. I have certainly learned about my weaknesses (they all bubble to the surface when under pressure), as well as discovered new strength and endurance (which I never realised I had).

And now Grace is two, a little girl so full of life.


Fortunately my business has not only survived the last two years, but has grown and developed. It has certainly had (and has) its challenges, but I keep learning along the way. And now it is time to start sharing and talking again.

My apologies to my regular readers for just disappearing for the last two years without any comments or indication of what was going on. I am back and will be posting regularly again.

With 48 post over nearly three years, I am certainly not a prolific blog writer. My goal has never been to write a lot, but to rather explore issues from new angles and stimulate thinking and hopefully action. The positive side–effect of this has been exposure for my business, which was part of the original goal. In reality this blog has developed into much more than a marketing tool – it has become a platform for me to spread and amplify ideas, ideas which hopefully help to make the world a better place to live in.

Looking back over the titles of the blog posts there is a mix of mostly environmental issues and engineering. I have been spending a lot of time thinking about the direction of my own life, as well as of this blog. There is a definite changing of season for me – a new and renewed direction and energy – and with that comes a slight change of direction for this blog.

That change of season has a lot to do with making a shift towards more "doing" and less talking. I have noticed that I draw the most inspiration from people who actually do (or try to do) important and interesting things, from David's fuel–to–electric vehicle conversion to a friend who helps get blankets to babies living in cold tin shacks.

For me that means spending more time doing some of the things I have talked about or had on my mind for a while (like developing some systems to speed up my design process), as well as engaging with organisations that are doing things that I believe are important (like this urban agriculture group).

This means that there will be a slight shift of focus in the writing here. There will be a stronger focus on how I am developing my company and design process, and I will try to open up as many of the inner workings as possible so that everyone can learn from what I am doing (and hopefully not make the same mistakes!) Even though the focus will change a bit, there will always be a strong environmental slant, as creating a cleaner and healthier place to live is important to me and a part of who I am.

For the foreseeable future my commitment to you is to write one blog post every two weeks.

Thank you for coming on this journey with me. I am glad to have you along, and would love to hear from you (and thanks to all of you who have contacted me).

I am sure you have been in that situation where you are struggling to solve some problem, and then you take a break (maybe a nap or shower) and suddenly – WHAM – the solution hits you right between the eyes. Our minds are in continual process even when we are not aware of it.

Taking breaks changes us. Long or short, they matter because we allow ourselves to change the focus of our minds, and that change in focus allows us to think more clearly about all the other things. When we are deeply involved in something (be it a hard problem or the daily matters of life) our perspective narrows and taking a break helps to open up our perspective – we get a new view on the world.

I have been able to take a long break from life and travel in the USA for a month. Travel always changes our perspective, and this trip gave me much to think about. Returning to my business and normal life probably gave me even more to think about. For the next while I will be focussed on some engineering design and process issues that I think can be improved upon, but I will continue to discuss the environment and how we and engineering interact with it.

For now, some thoughts on my USA trip:

• America has a throw away culture. Everything is paper, plastic and polystyrene and meant to dumped after using. Restaurants, coffee shops, rest rooms and homes – waste is everywhere. Americans generate far more waste than South African's do.
• I did not see energy saving bulbs anywhere (except my brother's house). Energy crisis? What energy crisis?
  
• When we see stats and numbers about waste and energy usage they are typically based on American studies. Due to the the above points it may not be fair to impose those numbers on South Africa. That means we need our own numbers, and our own measures. Using the US yardstick against ourselves will yield false results.
• We need to make sure we move towards a culture of efficiency, reuse and longevity – away from a culture of waste.
  
• It is hard to get a decent cappuccino. It is even harder to get it in a ceramic cup (I learnt to ask for a "to stay" cup on my last day).
• We need to learn how to be patient on the road. The Americans are really patient and courteous drivers. Most people's instant reaction would be that they have more policing. Is it more, or is it the style that matters? Also, do we really need to be policed to behave well?
• You can get just about anything you can think of (except a decent cappuccino).
• Nobody really knows or cares what happens in South Africa. We fool ourselves when we think our economic fortunes are closely tied to our political situation.
• South Africa has a soul, character and diversity which I am absolutely ecstatic to come home to.
  

I have been very fortunate to have been added to Alltop's engineering page (well, I asked and I received), as well as being listed at #16 on the top engineering blogs on EngineerJobs. My goal is to be in the top 5.

Thank you for your continued support as readers of this blog. I appreciate your time and attention to read what I put down here, and to make thoughtful comments on it.

Google Reader recently released a new feature which enables me to share some more of my thoughts with you.

I have never been a big fan of regurgitating other people's post and information on my own blog. I see this more as a place to try to share my own thoughts and ideas, or bring a bunch of info together to express a new opinion (I hope I manage to!). So far I have been pointing to blog posts that have stood out to me via the "Interesting article's I've recently read" section in the side bar.

The links in the side bar are the most recent items I have shared using Google Reader. Up until recently, it was only possible to share things that I received via feeds (see below if you don't know what a feed or RSS is). What the clever guys over at Reader have now done is to allow me to share anything, from anywhere and add my own note to that.

This is a new form of microblogging, but is far more interesting (to me, and hopefully to you) than the alternatives, such as twitter.

So now you can follow me and see my thoughts on interesting articles and information that I find. There are a couple of ways to do this.

1. Subscribe to my Google Shared Items feed. If you know how a feed reader works, you'll know exactly how to use that link to follow me. Otherwise, see the info about feeds and feedreaders below.
   
   There are one or two minor drawbacks with this, mainly that the original author's name does not come through correctly when I add a note.
   
   
2. If you already use Google Reader you can add me as a friend and my shared items will show up in your Reader. This is a slightly more complex process and requires you inviting me to chat with you via Gmail or Gtalk. You will need my Gmail address, which is duncan.drennan at the expected ubiquitous domain name.
   
   
3. [Update] As Francois quite correctly points out, you can also view my shared items as a webpage (which is linked to in the side bar).

Here is some info for those of you who have never heard of a feed or RSS. On this site subscribing to the feed allows you to immediately receive the latest posts straight into your feedreader.

A feedreader fetches information from a whole bunch of different feeds (e.g. this blog, a news website, etc.) displays them for you.

The beauty of this is that

1. You can subscribe and unsubscribe extremely easily (just add or delete a feed from your feedreader).
2. Delivery is guaranteed. Because you fetch the feed (pull) unlike email which is sent to you (push) the feed cannot get lost due to a firewall which is trying to stop spammers. Feeds are spam free!
3. You never miss a post. This is particularly important if you keep up to date by coming to check back here regularly. You could miss something, or worse, stop coming back ;)

Once you start using feeds you will wonder how you survived without them. I use Google Reader as my feedreader, but there are plenty of others out there. Here is a really useful video which explains RSS and feeds a lot better than I can.

Just a bit of background information on me....

I was born on 6 August 1979 and grew up in Port Elizabeth (South Africa). After school I went on to study electrical and electronic engineering at the University of Stellenbosch. I obtained my undergraduate degree Cum Laude and began my Masters degree directly after that.

My thesis was the design of a transverse flux machine - a high torque density machine (i.e. small, but with lots of va-va-voom). I studied under Prof. Maarten Kamper in the Electrical Machines Research group. After a year of full time postgraduate study I got married (to a very beautiful girl) and moved up to Pretoria. I continued working on my Masters degree until obtaining it in April 2005.

While in Pretoria I worked at Mecalc designing the front end of the MODACS system (low noise analogue design with a good dose of microcontrollers and FPGAs). I was there for just over three years until I decided to start Engineer Simplicity, so we moved to Cape Town and I have been running the company for over two years now.

Running my company has been an interesting, exciting and challenging experience. I have met and worked with some great people, and expanded both my skill and capacity to deliver exciting solutions. I have also slowly come to realise what is really important to me. As I blogged I found myself being drawn more and more strongly toward issues such as energy efficiency (which I have always been interested in) and waste management.

I discovered that what is important to me is to create products that help us move towards a cleaner and better world. So my focus is to find ways to create better products – products that make us happy and are sensitive to the world we live in.

I write about various things in this blog, from environmental issues through to engineering design. My goal is to explore these issues from an engineering perspective. Hopefully this inspires engineers to build a better cleaner world, and exposes people to new thoughts and ideas on how to create a better life right now.

I am glad to have you on this journey with me.

So here we are, the first blog post...well, really, here I am. My name is Duncan Drennan and this is my blog on business, design, electronics and a bit of politics. Right now I'm not sure what this is going to develop into, but I'm definitely looking forward to the journey. May it be as interesting for you as it is going to be for me.
