The Twelve Days of Obsessive Christmas Decorating day 5 late
Yesterday was a long day and it got late so this post is late.
I got the HO, HO, HO display done and it works. I had to re-wire the lights on the last part twice. And I think I figured out why the blue lights on the rebar Christmas tree don’t work. The controller uses Silicon Controlled Rectifiers (SCRs) to turn the lights on and off. The lights are LED which are also rectifiers. Rectifiers only let electricity go one way. If the SCR and the LED or connected against each other the current (moving electricity) can’t get through and nothing lights up. Reverse two wires and the electricity is moving.
I’ll flip the two wires on the blue lights tomorrow. The sun went down and it’s cold. The day was good. Not too much wind. We have a high pressure system off the coast that’s pushing the low pressure system up north and giving them snow and rain. We could use the rain down here. With the warmer weather I get more done, but it seems there is so much more to do.
I did not get the Christmas star up. The displays I am working on are home made. The star is one I bought at the store. Home made items are unique, no one else has one like it. Where the store bought ones can be found down to block, unless they are like mine and are so old no one has them any more.
The gate is finished for now. It needs new wood to cover it, but that can wait until summer and when I can get help. The gate is heavy and hard to move when it is not on its hinges. It also needs painting,but that is going to have to wait until the Christmas lights come down.
Many of the plants in the garden have gone dormant, but the orchid are about to bloom. The paper whites or narcissus are blooming along with the geraniums.
With the big display done after all these years I need to work on the antennas tomorrow. I may make up a couple of extension cords for one more run of lights.
I have some tow by fours left over from the gate project. How can I made a Christmas decoration out of them?
The Garden needs watering. Not as much as during the summer. And the weeds and grass need pulling before it rains and they take off. I have to dig deep to get the grass roots out or it just springs back with the first rain.
Stay strong, write on and stay warm.
