Underwater digital camerasWritten by Jakob Jelling
Underwater photography's is primarily focused towards entertaining and informing people and users themselves about what is happening in world of under water with aid of photography. The advent of digital cameras has opened up new horizons for such ventures. These digital cameras are not only handy and sleek but also they offer a spectral range of features that helps underwater photographers in their work a lot. In this discussion these special features of underwater digital cameras are necessarily been revealed and done justice to!
Looking at grass root level some of main features that users of underwater digital cameras must necessarily seek are as follows. They are applications for land mode, sea mode and external flash mode. This helps in shooting in any conditions in sea and obtains much better picture quality than ever before. Some other features are like instant delete option after each picture in both sea and external flash modes along with one-button operation features. These mentioned features provide sophistication as well as ease of control for photographers. Some more desirable features are expandable and good quality standard lenses, flashes and accessories.

These digital cameras can be aptly described as being effusively amphibious! Thus chances of water damage and flooding in these underwater digital cameras are greatly reduced and are hence extensively used for professional purposes too.
The Happy Tinkerer - Making Homemade Devices For The Fun Of ItWritten by Alan Detwiler
I've always liked to make gadgets and gizmos that have some function, either useful or not so useful. It started with simple things that many kids make - slingshots, a simple bow and arrow, a toy boat. Occasionally I made more involved items such as a canoe and a dune buggy. Then there was grass hut - 12 feet across, octogonal in shape, and thatched top to bottom with a thick layer of grass. I built it in a remote location, near a stipmine filled with water. Hauled cut grass in a 1972 Volkswagon convertible with top down. Piled grass high in back seat. It must have taken a dozen trips back and forth from a nearby hay field.
Simple things appeal to me more than costly homemade items. A small project lets me pursue an interest without interfering with other goals. A project with a small amount of time invested seems more like entertainment. Time spent earnestly involved in creation of something designed and made with ones own ingenuity can be quite enjoyable.
So now when I don't feel motivated to do more practical things I often turn to an idea about some device or other that I've wanted to try making but never got around to. I can recall many such improvised devices that gave me satisfaction and enjoyment.
Ideas for things to make come from many places. Most often idea comes from some need. I do a lot of keying of text using a computer keyboard. I tend to keep room temperature a bit cool, cool enough that my hands become uncomfortable. I ended up rigging a length of electrical heating tape wound in a large coil-shape to surround keyboard. Tying heat tape to a large piece of cardboard keeps it in place. It does a nice job of keeping my hands warm. I can leave room temperature set where I want it. As far as I know, you can't buy anything like that.
