Contentment of Perseverance – 94

PhD Life

An avocado, apple and a banana walk into a fridge. As part of my research, I am looking at how things degrade in the consumer environment. By consumer environment, I mean a refrigerator. I will be capturing the colour change of various salad products; then showing the resulting time-lapse images to ‘consumers’, so we can find out when people will and will not eat the product. Then we will be able to predict how long the shelf life should be based on the rate of colour change.

That is the simple explanation anyway.

Here is my test video looking at things that change colour quickly!

Each second of video is 2.5 hours in real-life. One of my collegues sugested I submit this to the tate modern. All I need to do now is think of a pretentious title. How about: Contentment of Perseverance.

Producing a system capable of this is something I would have never predicted doing during my studies, seeing as I have no background in computer science or electrical engineering – or tinkering for that matter. You would think taking a time-lapse video inside a fridge is as simple as putting a camera inside a refrigerator and pressing go. The kicker is that the light needs to be only on when the image is taken, as firstly, the light is not always on in a refrigerator, secondly light will affect the product that is being studied (as light affects plants).

Put the light on a timer? That would probably work as long as the clocks on the camera and timer are synchronised. Instead of trying to figure this out, I linked up the camera and light to a computer, and then the computer controls the timing of both, which keeps them in sync. A fraction of a second drift may cause problems over the 2-3 weeks I need the time-lapse to last for, it would be a disaster of the last portion of the time-lapse was pure darkness as the light did not come in.

By building this system, I have learnt so much about electronics, and I believe I could see myself as a tinkerer In future – where is my shed? It’s much more fun learning how to make things yourself rather than buying things pre-assembled. I come from a line of tradesmen and engineers, so I guess this finding is not so surprising. However, I do feel as though I should have done engineering rather than food science. Looking back, it does seem rather strange of the younger me chose to study food and nutrition.

If you could do it all over, what would you change?

Although I believe that if I did it again, I would do something else; I also know that this type of thinking is illogical due to the fact I have already done the thing I said I would do differently – hindsight.

  1. Being different from those who came before you is OK, though it appears you are utilizing that same spirit in another field. I suppose if I thought about it hard enough, and the way back machine popped up, I might think of something I want to change. However, everything I’ve been through made me the person I am now. And I’m at peace with it.

  2. I’d have used a game/trail camera and a simple thief-deterrent timer for the light. When the light turns on, the camera detects the “motion” and snaps a photo.
