I finally tested the rope ladder I've built. Well, I tested it yesterday and it was kind of a failure, but a learning experience.

Anyway: it does work. The workflow is:

1. Probably don't try this without rope climbing experience/training and a secured harness!

2. Use a thin throw line with a weight to make a pulley over a branch that will be the support. For the weight I used a steel carabiner that's normally attached to the...

I have built myself a rope ladder. It's about 7 meters long, made from 8mm polyester rope and beech rungs ~3cm in diameter, 35cm long. I drilled 1cm diameter holes about 25mm from each rung ends, rungs are supported by an 8-figure stopper knot below each rung.

Both side lines are separate, connected at the top to a carabiner. When deployed, the ladder is supported by a rope going over a suitable branch, anchored with a strap down near the ground.

Why would I need a rope ladder you say? To mount meshcore...

To start the week let's have another, dare I say, masterpiece from Mechina. This project is criminally underrated.

This isn't in the jukebox yet? What gives!

Gory details of my next build: a small meshcore repeater intended for wilderness deployment.

Would you use a Star Trek transporter if you were sure it functions correctly according to spec? So, it magically scans your body down to the last detail, deconstructs it and then reconstructs a perfect copy elsewhere.

It's a classic philosophical question about identity and continuity of consciousness. Will you actually die during the process? Or will the emerging copy actually be you? And then of course there are fun questions like: what if there are multiple identical copies? Or a...
