10gb fiber to my barn? Why not…

Don’t ever start looking at ebay when you are a systems engineer. You quickly find yourself convincing yourself that your home network is inadequate and should be keeping up with the multi-national infrastructure you work with day to day.

Imaging your Barn is Tokyo, your house is San Francisco… you need that 10gb connection to withstand 41 thousand simultaneous phone calls and to stream 6 terabits of media per hour! Well yes, i needed it. The man cave has needs.

So I began my research into fiber optics which admittedly I was a little behind on.

Fiber Optics vs. Coaxial Cables - The Beacon

Plan your attack

  • How far is the barn from the house
  • What type of fiber can I use
  • Do my switches support fiber?
  • What is the maximum length fiber I can run?
  • What types of connections are needed at both ends?
  • How much is this going to cost me? Am I nuts?
  • How can I get this project past the wife?

Vanagon Carpet install on the cheap

Wanted to pass this along to anyone who is interested. I recently picked up an 86 GL that was extremely scrubby, sorry PO. Kids, dogs, general mayhem must have been involved. I did my research on the different Sewfine, Gowesty, Busdepot kits but couldn’t bring myself to cough up 300+ beans.

Enter Lowes. Found this Mohawk 60x84in commercial area rug which seemed to be pretty close to original dimensions and color (denim in my case)

I pulled out the original carpet by removing front skid plate and wooden bench support.
Removed the 2 metal rails and filled the gaps with two layers of a black Tread Mat

When comparing old nasty to the new carpet I only needed to make one cut along the sliding door side. All other sides fit and had the edges seamed up.

I also cut out the square piece for the rear heater.

Installing was pretty straight forward, just lay down and push to each wall.

and the final product!!!! Total cost Rug = $34 Rubber = $12

  • Put the following files in that directory

1962 J.C. Higgins Camper Trailer

1962 J.C. Higgins Camper

I found this 1962 J.C. Higgins camper trailer at one of the VW swap meets I go to. It’s made of mostly aluminum so no rust. J.C. Higgins was actually a brand sold by the Sears Roebuck Catalog. The original manufacturer was Apache who later mas produced the more recognizable Popup campers you see today. But these grey aluminum beauties were some of the original trailer campers produced.

A little refurbishing on the wiring and lights and we are road legal! The camper came with a full canvas tent that covers the trailer and extends about 6 feet to over to one side.

The canvas on the floor / bottom needs to be replaced and I haven’t quite talked my wife into that project but more to come…

Since someone asked for an update, here it is!
So we have used this old girl on many camping trips since last we spoke. But before we left, i spend some quality time cleaning up her aluminum. Using different grades of polishing compound and a buffing attachment to my drill, I was able to bring back the original mirror finish on the camper.
Purchased the compound at “Runnings”
We primarily use the camper for storage when camping which has 4 large compartments 2 on each side. Also added my families original igloo cooler.
We did actually put up the tent one night and used an inflatable bed, but i never made it through the night and ended up back in the warm quiet VW bus.
Last season, i actually added Solar panels from Harbor Freight to the top which power two deep cycle batteries. This could power our camp for a week or so, but mainly used for cool lights around the camp.
New tires were also purchased and back spare painted.
New wiring was added for lights / inspection
More to come!
