Fish Finders, Embedded Linux and Graphics
By Paul Anderson
Here I am up at rustic cabin in Northern Wisconsin enjoying some time off the grid. I feel like Ralph Waldo Emerson getting in touch with nature, and exploring Transcendentalism, except for one minor detail: I have a wireless connection. Emerson was quoted as saying “Nature hates calculators,” and I’m not sure what he would think about the billions of connected devices scattered across the landscape. Not to worry, I’ll be back unplugged soon enough and enjoying some quality time in the “digital free zone.”
I tried my hand at some fishing this week on the little lake we are on. Even though I’m a gadget person in general, I am a very low tech fisherman. With the help of my brother in law, my kids and I just fished the old fashioned way, with a pole, hook, bobber, and worm. It didn’t take long to find the fish, or for the fish to find us. However, there are plenty of high tech anglers out there that use everything from advanced weather forecast maps, fish finders, and even underwater cameras. I find all that technology interferes with the peace of mind that I am looking for when doing things like fishing, but perhaps that is because I am fully immersed in technology as a career.
Modern high end fish finders, GPS units, and other electronics equipment used in the outdoors have become much more sophisticated. The users of deeply embedded devices have come to expect a graphical user interface, low power consumption, and reliability. A similar trend can be found across a spectrum of deeply embedded devices, including industrial control panels, medical equipment, military applications, and of course, consumer equipment.
