Australian Engineering Week 2010

Today begins Australian Engineering Week 2010.  You can get a full run down on all the events at Make It So which you might recognise as a tribute to the Star Trek series. 

It got me thinking about why I got started in Engineering.  It was music.  I had done 1 year of a Science degree focusing on Physics and Chemistry at Deakin University and had taken a year off because I had no idea why I was doing a degree.  So I worked a few mundane jobs and joined a pub band.  We were pretty bad.  I had only started playing guitar a year before that.  The equipment was low grade and needed a lot of maintenance and I was constantly trying to improve the PA, the mixer, the guitar and amplifier and the effects.  They were all analogue electronics in those days. It was mostly trial and error and occasionally trial and success!

What if I knew enough about Electronics to be able to improve, or even design from scratch, my own guitar effects pedals, guitar amplifiers, mixing desks and PA system?

But where would I learn that?  So I went back to Deakin University and asked them.  And they suggested Engineering.  I had mostly thought of Engineering as roads, buildings, bridges and transport so this was a new type of Engineering for me.  But I was also hooked.

Four years later with a First Class Honours Degree in Electrical Engineering I was doing just what I had set out to do.  Electronics Design was now a part of who I was, not just an area of study.   My rig was designed and built by me.  And I also doing electronics design and custom pro-audio equipment construction for recording studios and professional musicians.

So check out Australian Engineering Week 2010 and for some more insights into Engineering you can also read the blog at Engineering Education Australia.

This week I was the recipient of an Exponential Entrepreneur of the Year award.  Last year we were received 2 awards for technical excellence when we won 2 of the 15 EDN Innovation awards handed out in Australia in 2009. 

So I was very pleased to be receiving an award recognising the business side of Successful Endeavours.  The award was presented by Dr Marc Dussault of Exponential Programs and recognises entrepreneurs and business people who have demonstrated excellence deploying exponential strategies in their business by profitably creating exceptional value for their clients in a manner that is both measurable and sustainable. The award received was in the category of Engineering Consultant and was one of only 6 handed out in 2010 and the only one in that category. 

Exponential Entrepreneur of the Year 2010 Ray Keefe receives his award from Dr Marc Dussault.

You can read more about the awards at Exponential Programs Entrepreneur of the Year Awards page. 

The main reason for this post is to touch on the most significant aspect of this award for me. I once said that as a Business Owner I made a pretty good Engineer.  The past 18 months has a seen a transition away from that to the point now where I can say that I am an Entrepreneur who is also an Engineer.  Engineering is a Profession and so it isn’t something that suddenly stops being relevant.  Our education and mindset is all based on practical problem solving through the use of technology while balancing performance, risk and cost.  And we apply this skillset and mindset to most aspects of our lives, even when it isn’t the only way to go about it.  So I am very pleased to be making this transition.  Not only is our business better for it but our clients are as well. 

And I also thank our clients for the trust they have placed in us to deliver Electronics Design and Embedded Software Development for their next generation of market leading products, the vast majority of which are still made in Australia at a profit. 

Here is a picture of the Exponential Entrepreneur of the Year award certificate.

Electronics Design for Green Manufacture

This is not as straight forward a topic as it might at first seem to be.  And this is because there isn’t yet a unified agreement on exactly what Green Manufacture means.  And like most Design Issues, you cannot do Electronics Design without clear requirements.  So what are the requirements?

Here are some Green Manufacture requirements or targets:

• reduce product Power Consumption
• reduce manufacturing Power Consumption
• add Renewable Energy options to the product
• add Renewable Energy options to the manufacture process
• reduce pollution or waste in the manufacture process
• reduce energy involved in upstream or downstream processes
• reduce pollution or waste in the upstream or downstream processes
• increase product life
• increase product utility
• increase manufacturing plant utilisation

I guess you can see the dilemma.  It can be hard to know which target to aim for.  Am I doing the Electronics Design with the product, process, life cycle or ecosystem issues as the primary concern?  And how do I balance these concerns?

Here is one excellent article that also discusses this topic Green Supply Line.

Electronics Design can be Green

One major thing we can do is reduce the product Power Consumption.  We are coming out of a phase where a mains plug pack power supply was considered an ideal way to avoid compliance costs when designing new products.  This has led to a proliferation of low efficiency always on powered devices.  A recent look under my desk reveals the problem we have as Product Developers where every device I use is either USB Powered or mains plug pack powered.

So a first step is to review this whole approach to supplying power to devices.  We have made steady gains in the area of Power Consumption reduction for the devices themselves.  Now it is time to do a similar thing on the Power Supply side.

Energy Harvesting

This is a new area that hasn’t yet reached mainstream development.  The idea is that you can utilise the ambient environment to get power for free.  Or at least you aren’t directly requiring extra Power Generation.  Hence the name, Energy Harvesting.

How you do it and the Electronics Design and Electronics Technology required to make it work are still being defined but there has been some interesting new progress.  Some key players are:

Linear Technology – new Energy Harvesting Integrated Circuit

Enocean – are front runners in bringing Self Powered Wireless devices to the market

What is Energy Harvesting?

This is where we use Electronics Design and Electronics Devices to generate power from the Ambient Environment.  The result is a product that doesn’t need to be plugged in and recharges itself automatically. Some of the Energy Sources that are used are:

• Light
• Thermal differentials
• Vibration
• Chemistry
• Pressure differentials
• Air Flow

One example of a product that does this is the Enocean Light Switch where you can just put it where you want it.  And if you change your mind, just move it. Now wiring required.

Right now the technology is still more expensive and so take up is slow.  But as it develops and the price comes down that will change.

We are in for some interesting times.

Electronics Design To Save Energy

We have looked at how Low Power Electronics is a green strategy because it reduces the amount of power that has to be generated.  And then we looked at a range of options for Reducing Electronics Power Consumption.

Now we are into specifics.  The last post looked at Sleep Modes For Microcontrollers and how extending the Sleep Period and reducing the Sleep Current could dramatically Reduce Electronics Power Consumption.

Saving Electronics Power When Awake

The next logical step is to ensure that Power Consumption when awake is also reduced as much as possible.  This can be a little tricky to get right as it can sometimes eliminate all the benefits you built up with you sleep strategy.  The reasons for this are:

• you can use Analogue Electronics to reduce software power requirements but it has to be turned off during Sleep Mode
• if you do turn the power off to Analogue Electronics then there is a Settling Time after it is powered up
• using Smart Electronics Chips can increase overall Quiescent Current
• unless the Startup Time and Shutdown Time are quick, these can dominate the Power Consumption

Now there are some Software Architecture issues that affect these, especially the last one, but we will look at that in another post.  For the last part of this post we will address the Electronics Design issues that have been raised here.

Electronics Design – To Save Power

Electronics Design can address these Power Consumption issues.  Here is an example of a Power Consumption curve where an RC Time Constant must be taken into account to minimise average Power Consumption.

RC Time Constant affect Power Consumption

Here is a list of general strategies to select from to reduce Power Consumption:

• using the lowest feasible Clock Rate so Clocked Devices use less power
• using shorter Settling Times particularly by controlling RC Time Constants
• select semiconductors for lowest overall Quiescent Current taking awake and sleep operation into account
• ensure streamlined Startup and Shutdown operation

The overall Quiescent Current issues often gives the most difficulty.  This can be addressed through Design Simulation either by SPICE, Software Modelling or a spreadsheet.  For simpler systems the spreadsheet is often the easiest solution to implement.  For very Software Intensive Systems the Software Modelling approach is the most reliable method.  This will allow you to construct scenarios and be able to predict the Power Consumption implications for each of them.

For our Electronics Design and System Test methodology we often create a full system Software Model and so it is easy to use this same Software Model to accumulate the power consumption as it runs.  This can also be automated and so simulate months of operation very quickly.

Next we will look at the role of Embedded Software in ensuring Power Consumption remains as low as possible.

Electronics Manufacturers are the people we serve

A common question we are asked is what sort of Electronics Manufacturers do we Develop Products for?

So I thought I would compile 3 lists:

• The first is a list of the Electronics and Embedded Software product types we have worked on
• The second list is a list of the industries we have Developed Products for
• And the third list is the Technologies we have worked with so far

I might have to regularly update this third list since knowledge and technology are constantly expanding.  Before I do the lists I’d like to present a video that specifically addresses this last point.  This is very much worth thinking about.  Enjoy.

Electronics and Embedded Software Products

Did you notice the section from 1:45 to 2:15?  We are being prepared for jobs that don’t yet exist, technologies that haven’t been invented, and problems we don’t even know we will have!

Here is the list of some of the Electronics and Embedded Software Products that do already exist and which we have helped to create:

(more…)

There are a lot of news feeds running this story.  Here are a few:

Timeline ABC News
IEEE Spectrum
National Geographic
Business Journal

And when the Internet first began, no-one knew what we would be doing with it today.

This has happened to a lot of other technologies.  Low Cost Electronics and Low Power Design that can be Battery Operated has made many thing possible such as mobile phones, portable computers including netbooks, notebooks and laptops; portable media players, MP3 players, PDAs and the list has just begun.

But where is it going?  Realistically, you need a few things to come together and the environment and carbon footprint considerations now sit alongside the more traditional requirements such as:

• Low Cost Electronics Manufacture
• Low Power Electronics Design
• Design Tool Productivity improvements
• Electronic Design Automation
• Increased Processing Power per milliwatt (mW)
• Embedded Software of immense complexity and flexibility
• Flexible circuits
• Transparent Electronics
• Compact component size
• Reduced Polluting and Increased Recyclability and reuse

Vernor Vinge looked into what might become of this in his book Rainbows End which I recommend as a good read and full of well thought out ideas about how augmented reality might operate including concepts such as  wearable computers, gesture recognition, graphic overlays, the equivalent of doing a Google search on any object in your field of view, and other ideas like that.  It is set 20 years from now.

The most interesting for me was the way work was conducted in the future and how much advantage there was in having 100,000 people as affiliates on a program.  Pay is based on royalties for contributions.  You choose what you join and contribute to.  Your income directly reflects the product of your contribution and your negotiated royalty rate.  A large company has 3 direct employees and everyone else is an affiliate on one or more programs of work.  This produces phenomenal synergies.

It will be very interesting indeed to see how much of his vision matches the future.

EDN Innovation Awards Finalist

EDN Innovation Awards

This is a bit of a different post.  I’m pretty stoked that we are finalists in the 2009 EDN Innovation Awards in 2 separate categories.  The award categories are:

• Best Application Of Analogue Design
• Best Application Of Design Software

Here is a list of the EDN Innovation Awards Finalists and we are in the 2 categories at the bottom of the page dealing with Analogue Design and Design Software.

So I thought I might let you know a bit more about the project, and also give a public thanks to Pablo Varjabedian of Borgtech for allowing us to put the project forward. We design Electronics and Embedded Software products primarily for Australian Electronics Manufacturers.  Our focus is outstanding Electronics Design that will propel them into a world class competitive position while delivering improved profit margins.  Low Cost Electronics Manufacture but with outstanding performance and reliability.

We routinely use non-disclosure agreements, NDAs, with our clients and so don’t usually get the chance to put our design work forward for awards because we will never disclose a client’s Intellectual Property, IP, without their express permission.  In this case Borgtech gave us permission and so we were able.  As you can probably see, there is a real benefit to the client in allowing the award application because they also get recognition for the product.

This is also not an unusual project for us. We have done a lot of outstanding work over the 12 years we have been in operation.  So it is good to have some of it recognised by the Industry we are so passionate about.

Electronics Design Details

This project was an example of our Project Priorities Perspective in action.  In this case Performance was the primary concern with cost coming second and time coming last.  We spent the time to get the performance up and the cost down.  There was an earlier post on one aspect of this project where we looked at Analogue Electronics as a way to improve battery life in a Low Powered Electronics Data Logger.

The Electronics Design trade offs were:

• OH&S or Operational Health and Safety – must protect users from hazardous voltages
• Low Power Electronics – operates from 3 AA cells for up to 6 months
• Convenience – Analogue front end completely Software Controlled
• High Reading Accuracy – millivolt resolution over +/-10V range with 60dB Mains Rejection

There were many other Design Requirements but the above list are the core Electronics Design Requirements addressed as part of the award nomination.  Below I will look at each of these in turn.

Protection From Hazardous Voltages

Now lets look at the hazardous voltage issue in a little bit more detail.  The voltages in questions were:

• 5000V, 5KV, for 2 seconds
• 250VAC continuously

These come about due to the conduction of Lightning Strike Transients or Mains Leakage Voltages onto the Pipelines and Storage Tanks monitored for Corrosion Protection status.  The Analogue Electronics front end had to provide protection against these cases while meeting all the other Design Requirements.  And of course quickly settle so that only the readings during the disturbance were affected.

It also led to the use of an 802.15.4 RF Telemetry Link because this meant the monitoring PC could do Real Time Monitoring without hazard.  Many other products in this industry use RS232, RS485 or even I2C connections for monitoring, configuration and upload of the Data Logger Records.  In the case of the Borgtech CPL2 you can put it in place and then configure it and start the logging with no danger to the operator apart from the moment of electrical connection.  And the initial part of the run can be monitored to ensure everything is correctly set up.  Otherwise you could get a months worth of data that was useless.

And finally, because of the power budget and the possibility of the batteries going flat, the Analogue Electronics had to survive the above Abuse Voltages unpowered!

Low Power Electronics

The Borgtech CPL2 is a Battery Operated device.  There are several reasons for this but the 3 most relevant are that it is:

• IP68 sealed against water ingress – it is often installed in a pit that can flood
• Must operate remotely from a convenient power source
• Protects the operator and PC from Transient Voltages since there isn’t a direct electrical connection

But this is also part of the challenge.   For convenience it used off the shelf batteries you can buy at any service station.  But to get 6 months life required a strong Power Management approach including powering down anything not in use including the Analogue front end.  If you are taking a reading every minute over six months then most of the device is off most of the time.  In this mode the average Power Consumption is 37uA.

Analogue Electronics – Software Controlled

The Borgtech CPL2 handles both Current Shunt and voltage mode readings. The Analogue Electronics were designed to have a software selectable full scale range of +/-10VDC and +/-150mVDC so that is could do either mode of operation from the same input. The previous model required a different connection for each of these modes and most other models on the market are the same.

And all of this while maintaining accuracy, abuse voltage protection and low power operation.

High Reading Accuracy

By the standards of an Agilent (I still want to call them Hewlett Packard) 6.5 digit laboratory multimeter our millivolt, mV, resolution at +/-10VDC isn’t rocket science.  But for a device with the Voltage Abuse Protection and Low Power Electronics requirements we had to meet, it is pretty good. Another small twist you might not recognise is that it is +/-10VDC.  This means you can monitor it with the polarity inverted and fix it up later on by inverting all the readings. The previous model was unipolar and so you couldn’t do this meaning you could have just wasted a month.  And then there is the live monitoring so you can see what the readings look like before leavign the unit to log away in the background.

EDN Innovation Awards

On 17 September 2009 we know the final outcome but either way I am pretty happy to have the recognition this project has already received.

Analogue Electronics

Sometimes you come across a post elsewhere that is absolutely on the ball.  When it comes to Low Cost Electronics Manufacture, Analogue Electronics Design and Analogue signal integrity, the three are closely linked.  Many a product has had expensive technical band-aids added to it to cover up poor underlying Analogue Electronics Design.  So avoiding the poor Electronics Design will avoid the unnecessary expense.  This is especially true when it comes to the two most misunderstood aspects of Electronics Design:

• Analogue Electronics
• Radio Frequency Electronics (RF Design)

For this post we will focus on Analogue Electronics and some simple strategies to avoid problems.  A problem you don’t have is a problem you don’t have to fix.  The key to success with Analogue Electronics is very simple:

• Know what you are doing
• Do it right the first time

So for some excellent advice on addressing Analogue signal integrity issues check out this post on Analogue Signal Integrity.

And for a general view of how to avoid problems here is a simple strategy to avoid Signal Integrity Issues.
