Fire from… water

DIY water torch electrolyzer for soldering metal

Anyone who reads the description of the electrolyzer I developed will be convinced that a few liters of water are enough to obtain a high-temperature flame (200° C).

Therefore I had to make another version. The Read more…

“Mixer” for concrete

DIY barrel concrete mixer: scheme, paddles, and trough

In two evenings I built a simple but productive concrete mixer that makes work on country-site construction much easier and faster. I was building a garage from 400x200x200 mm concrete blocks that I formed myself using formwork and this very mixer. It is made from an old 50–60 litre barrel. Anyone can assemble something similar Read more…
