Almost a decade ago, I purchased a house with a garden plot in a village. The plot needed to be cultivated, but without machinery, this work was overwhelming, and there was no money left for it.

I made a device that allows you to quickly check the operation of the trailer’s electrical equipment alone. Read more…
For many years, I have been mounting my amateur radio homemade devices in universal cases made according to a single scheme. This is a frameless construction consisting of two U-shaped parts: a base and a cover. They are made from sheet steel of the required thickness (usually from 0.3 to 1 mm), which when connected Read more…
