>>234806I did what was shown in the image, but did not lift it to my back; back and forth motion and too much load on one side of this setup makes the entire structure fail; the computer would have slipped out if I jostled too much.
To improve, I would need longer than my current 21 foot rope, since I doubled it up in order to provide a better work load.
I can see this working well with thicker rope; maybe 3/4 inch or something more, but there needs to be a way to lock each strap; knots are necessary in this setup because I want rigidity.
It is a good start, though. I definitely need to scale down the weight (lifting a computer over and over again is annoying, if not strenuous) but keep something of similar unweildy size.
