First project is a birdhouse made out of an empty cashew container. The unique aspect of this is that it cost so little to make, and the bottom of the birdhouse unscrews, easily, for fall cleaning. I used the plastic container, a small plastic cup for the perch, and a rubber watchband to line the jagged hole cut in the front. The hole is big enough for the Bluebirds, Wrens and Swallows that visit my yard. I consulted a couple of sources for recommended opening sizes. I also noted the recommended height to hang the house, based on the common breeds I've targeted. I used some spray paint I had in the cupboard to paint the clear container. I drilled several holes near the top for ventilation and a couple of holes to use to attach a wire bail so I can hang the house from a clip or hook on the on one of the wooden posts I have in the yard and or the greenhouse.

First project is a birdhouse made out of an empty cashew container. The unique aspect of this is that it cost so little to make, and the bottom of the birdhouse unscrews, easily, for fall cleaning. I used the plastic container, a small plastic cup for the perch, and a rubber watchband to line the jagged hole cut inthe front. The hole is big enough for the Bluebirds, Wrens and Swallows that visit my yard. I consulted a couple of sources for recommended opening sizes. I also noted the recommended height to hang the house, based on the common breeds I've targeted. I used some spray paint I had in the cupboard to paint the clear container. I drilled several holes near the top for ventilation and a couple of

holes to use to attach a wire bail so I can hang the house from a clip or hook on the on one of the wooden posts I have in the yard and or the greenhouse.

I used a cover from another empty container for the roof and extra insulation. It has an air gap under it.

My 2nd Junk project was made with some halogen lamps a friend gave me. I tried the set up with my lab power supply after trying some old 12v power bricksI had. The bricks were not powerful enough (low amperage) to light the 25v lamps.

I've enclosed a sketch of the proposed project to construct a string of adjustable lights. The lights can be moved by sliding them along the double track of copperwire carrying the power. The track is strung between two walls in the room and the wires are separated by running them through holes drilled in the dowel. The

dowels could be painted, as they are fluted dowels used for joining wood with glue and clamps. Power runs to one end of the track, and the other end is terminated in some dowel tacked to the wall, or held with a “U” shaped clip.

I have since found a power supply through Amazon for only $4.01 plus shipping. It would require a power cord...stripped and screwed to the 110 terminals on the rear of the unit. Plug in the power after attaching the track power wires to the screw terminals on the unit. Voila. An adjustable light rail in any room. Safe, lower power, cheap.
