I've always liked to make gadgets and gizmos that have some function, either useful or not so useful. It started with the 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 the 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 the cut grass in a 1972 Volkswagon convertible with the top down. Piled the grass high in the 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.

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. Each project gives me something to be proud of and relief from the tedium that often must be endured with more practical endeavors.

Ideas for things to make come from many places. Most often the idea comes from some need. I do a lot of keying of text using a computer keyboard. I tend to keep the room temperature a bit cool, cool enough that my hands become uncomfortable. I ended up rigging a length of electrical heating tape

Mixed Reaction To Obama Business Tax Breaks Plan
Some think the proposal will be another cash-for-clunkers-style tax break that probably won't have much of a long-term impact. But others are more enthusiastic about the plan to allow U.S. companies to write-off all investments through 2011.

As we build and invent, we become more able to manipulate the physical things that are around us. We gain pride in our ability to do so.

The thoughful tinkerer comes to understand that even simple things are complex. And what is complex can be summarized in simple terms. This understanding inspires appreciation and enjoyment of the physical world.

Both intuition and logic are used to make a homemade gizmo. The more the two abilities are used together, the more powerful the combination becomes. A strong partnership of reason and creativity helps a person to produce and enjoy life.

It is fun and satisfying to conjure up and build simple devices. Those created items command more appreciation than more casually acquired, purchased items. And it feels good proving that imagination and ingenuity can make life better. Having witnessed first-hand the process of invention, we wonder what other things we can achieve.
