Picture of simple adjustable portable spot light
Having a powerful portable lamp is very useful in makers life. Of course there are very good solutions which you can buy for few bucks, but time ago I loved to work wood, and I've made this nice spotlight stand. You can attack it on any surface and you can adjust the spot at the direction you like.

Step 1: The joints

As I said main material here is wood :-)
Just cut four cylinders from an old broom handle, length could be about 4 cm.
Then you need a small wood board, at least 1 cm thick.
Make 6 mm holes in both ends of the cylinders, and also on a side of the board.
I've also glued on the bottom side of the board a rectangle of rubber of the right dimensions, to improve the adherence on any surface.
One of the cylinders has two little hole instead of a big one, they're to screw the spotlight holder, so measure the screws stem to find the right diameter. The groove made with a file is not essential, but it keeps the wood far from the hot glass of the lamp.

Step 2: The bars

These aluminium rods are from an old TV antenna, they've a diameter of 6mm and they should fit tough in the holes.
Cut four pieces from them, and bend them at these shapes you see in the picture. There is no need to be very accurate, just be sure to have about half length of the wood cylinders before the fold.

Step 3: The light

The light source is a 12V halogen spotlight, you can also buy very good LED spotlight with the same pins. These particular glass spotlight has a groove on the opposite sides of the stem, and I've used it to make the connection with the stand. Because this halogen light becomes very hot you have to use something heat-resistant. I've cut an U shape from an aluminium plate, which will hang exactly the light on the grooves. Two holes in the plate allow you to screw it on the last wood cylinder.

how do these joints stay tight? I'm assuming there are some tight tolerances to keep it from flopping around but moving it a couple dozen times will likely compress the wood to the point where the rods will fall out too easy.
