glowing rods

Not really, maybe it got your attention.  This is a heatsink.  I’ve photographed them before, here and here. Most modern electronics devices use them; heat is the enemy of electronics.

In modern electronics, heatsinks are made of aluminum, primarily because of cost. Copper is a much more efficient heat exchanger, but it is more expensive and much more difficult to machine to exact tolerances.

I saw a piece of ‘old’ electronic equipment in the scrap bin that had copper heatsinks, so I removed them because I though they looked cool.  I hope you agree.

The photographic setup was very simple (just my speed).  I covered a spare tripod head with a black cloth and set the heatsink on the cloth.  The tripod was placed next to a window, with bright sun shining in.  I played with the tripod to get the angle of the heatsink just so.  In the shot below, I used a cheap LED flashlight to light up the part of the heatsink that faced the camera.  The sunlight was coming from the left.

Here’s one angle.



To give you a better perspective, here’s one from a little farther away. I like how the one rod is twinkling.

    It’s a good shot, I like the way certain spots sparkly.

    Very cool! Or should I say “hot”?!!!

  3. Wayne, your heat sink photos have a wonderful pattern and great light. Your photos have an abstract quality. A want to thank you for your comment on my blog today. It made me smile. I think Andy is correct about that tanker not hauling coffee, but it does make for a funny sign.

    Well, heat sinks make great photo ops and I learned something too. Speaking of tolerances, my son in law started working for Makino which makes those kind of CNC machines.
