I am building a new deck.

 I am building a new deck with 2x6" and Trex flooring.  The handrails are Veranda available at Home Depot. This picture is the framing using 10 and 12 foot 2x6's. In the foreground is what remains of the old deck.

Then I covered the flooring with 12' Trex boards.  They are actually 12 foot 1/2 inch to 12 foot 1 inch in length.  I only had to cut one as they are slightly longer than the 12' 2x6's.

Next was adding some handrails

I made some temporary steps.

Then finally adding some stairs and some handrails for them.

There is still some trimming to do such as skirting but for the most part it is working.

Build Your Own LED Wall

I have been building my own LED walls.  So far I have two of them, one uses P4 indoor Panels the other uses P5 indoor panels.  

All of the panels were purchased at huge discounts.  Here are some pictures of my eBay purchases for a total of 35 P4 panels.  You have been told that you cannot intermix LED panels.  I have used three different types of panels and a totally red, green or blue image shows that they are obviously not matched.  However, real images dont show up the mismatch nearly as much!

Most P6 panels can be connected together by metal brackets that have holes on 1 inch centers and are found at most hardware stores. P4 and P5 panels use 3D printed junctions and 3/4 by 3/4 aluminum rails for the outside edges.  I also have a mounting adapter for 5A-75B receiver cards that can control up to 8 strings of LED panels on thingiverse.

This is a schematic of a typical setup.  The 5A-75B can only control strings of 6 panels with the default lessings.

Here are two pictures of some assembled LED walls.  The second does not have the top and bottom aluminum rails installed and the vertical rails were moved to the middle of the panels so they would match the hanging loops spacing.

To keep the LED walls so that they are almost flat to the wall I use external power supplies.  Each power supply can run 15-20 LED panels.  I use 12 Gague speaker wires and 50 amp connectors to connect the power supplies to the panels.  I have soldered the power cables together or used binding posts to connect the power cables together.  The white plastic binding posts with holes that you insert the wires into seem to work the best.

Here is a picture of a P6 panel system with binding posts connecting the power lines together.  You can see that is is more dangerous than soldering the wires, and though matter how tight the screws are, somehow the wires will come loose.

The next pictures show the two types of binding posts, Regular and white with holes for the wires.

There are three different type of LED panels but did you notice that in the pictures above?  Here is red, green, blue and white test pictures. The blue makes the location of the three type obvious.  the red and green are harder to tell them apart.

Now the white picture has a different shade on the left side.  Why?  It was power supply overload!  The left side is using a different power supply.

Mini-Split Line Cover Problems

I have now installed three mini-split heat pumps.  I would only recommend the MrCool ones as the flared line sets seem to always leak. One of the issues is in covering the line sets.  Some people use the plastic eves, and I have done that as well on an existing HVAC installation. This one installation took two of the line cover kits at $39 each, and then I was still short one straight coupler.  So I designed my own couplers and 3D printed them.

Here is a picture of the first two couplers that I designed.  Later I came up with a design with hidden screws. I did not have white filament so I had to spray paint them to white.  My designs are on thingiverse.
