components for the go box, but how did I assemble everything?<\/p>\n<p>First, I had to decide how to mount everything in the box so that it was portable and things would not move around.\u00a0 This is somewhat problematic with the aluminum case as it is very thin.\u00a0 I decided that some screw heads would just have to show in the top and bottom of the case, but I was ok with this.\u00a0 So, the first step was to add some wood inserts in the bottom of the case to make sure there was added support for the power supply, the heaviest piece of equipment to be mounted.\u00a0 I cut a piece of \u00bc inch plywood to fit the bottom of the case and put it in place.\u00a0 I then drilled four holes through the wood and the bottom of the case, and ran bolts through the bottom into the case.\u00a0 Nuts and lock washers completed the \u201cfloor\u201d.\u00a0 To have a little more support for the supply and the Rig Runner, I added a strip of \u00be inch plywood at the spot where those two pieces of equipment would be mounted.<\/p>\n<p>But how was I going to securely mount the power supply?\u00a0 After some thought, I went to the local Home Depot and purchased two small drawer handles (\u201cgrab handles\u201d) and mounted them with screws to the \u00be inch plywood so they were on each side of the power supply case.\u00a0 After securing the handles and placing the power supply, I ran two large Velcro straps through the handles and around the supply.\u00a0 After making sure both straps were very tight, I closed the lid and picked up the case to test the installation.\u00a0 The power supply did not move!<\/p>\n<p>After testing the power supply, I installed the Rig Runner on the \u00be inch plywood board with two screws.\u00a0 From there, I mounted the USB Buddy to the \u00bc inch plywood with super strong 3M outdoor double sided tape.\u00a0 The case I use for my RPI has holes for two mounting screws and I used those to secure it to the \u00bc inch plywood floor.\u00a0 The DVAP was attached to the top of the RPI with Velcro tabs.<\/p>\n<p>But what about the monitor?\u00a0 I knew I wanted it mounted in the lid of the case, so I cut another piece of \u00bc inch plywood and secured it to the top of the case in the same manner I secured the floor to the bottom of the case.\u00a0 From there, I used the mounting frame that came with the monitor to secure it to the \u00bc inch board in the lid.<\/p>\n<p>Once all of the hardware was installed, I had to decide on the wiring.\u00a0 I had previously used this case with another ham radio application and had drilled two large holes in the side of the case which were then finished with large rubber grommets.\u00a0 I decided to use the hole towards the back of the case for the power cord for the power supply.\u00a0 The hole in the front side of the case would be used for the USB cords for the keyboard and DVAP.\u00a0 I then ran the DC power wire from the power supply to the DC input on the Rig Runner and connected the power poles from the monitor and USB Buddy to two of the Rig Runner\u2019s outputs.\u00a0 Finally, I connected the composite video cable and keyboard cable to the RPI and the DVAP to one of the USB ports on the keyboard.<\/p>\n<p>I plugged in the power supply and held my breath when I pressed the power switch.\u00a0 After a moment, I saw the RPI bootup sequence scrolling on the monitor, and eventually the DVAP software was displaying on the screen.\u00a0 Success!<\/p>\n<p><a

enough to carry just about anywhere and provides great flexibility.<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/ab4bj.com\/wordpress\/wp-content\/uploads\/box2.jpg?ssl=1\"><img data-recalc-dims=\"1\"
