Cutting foam or polystyrene sheets with scissors or a saw is an unpleasant task, but with a hot wire, these materials are easy to slice through. You can buy hot wire cutters for just a few thousand forints, but it’s also easy to build one yourself using the transformer from an old reading lamp, a … Read more
Architects have been interested in mobile buildings since the end of the 19th century. In nature, most things move in some way, whereas traditional architecture creates rigid, static things out of stone, wood and, more recently, steel and glass. There have been various attempts to bring buildings to life in some way, one trend being the revolving house.
Anyone working with electronics will eventually hold a component that you need to identify—what it is, how its legs connect, if it’s the right value, or whether it works at all. Testing with a multimeter A knowledgeable person can learn a lot even with a basic ohm-meter. Some multimeters include diode-test or transistor current gain … Read more
The JYE Tech DSO 068 is a do-it-yourself oscilloscope kit that’s easy to assemble.

As I write these lines, there is half a metre of snow under the window and it is -10°C. The sunlight is playing nicely on the bruised trees, but the cold is evil. If we have to get out of our gloves, our fingers quickly get cold, our skin starts to burn. The blood circulation to the back of the hand deteriorates rapidly, and the gloves are of no use. It’s better to put your hands under a coat or use a hand warmer.
There’s something delightful about the way crisp apples and creamy cheese meet the mild sharpness of spring onions. At first, the flavors seem almost too different to belong together — yet after a quiet rest in the fridge, they soften into harmony, like old friends who’ve finally found their rhythm. This salad is fresh and … Read more
This gadget is actually a continuation of the glimm lamp project. No, I don’t keep horses or deer cattle, so I don’t have a light bulb. However, I do run into electric shepherds while walking through the woods, and it makes me wonder whether or not there is a jelly in it. This thing, which is barely bigger than a pocket knife, is designed to find out.
I’ve always been fascinated by gas-discharge lamps. I don’t know why—perhaps simply because they glow in the dark. Or perhaps because they don’t always shine with a steady light, but sometimes flicker a little, as if they were alive, or burning like a flame. Or maybe because it seems as though the light is created … Read more
This Easter was spent in quarantine. It was a great opportunity to take advantage of the sunshine to draw pictures with light. Let’s replace the sterile electronic world of digital cameras with a dip in the water and think back to the 1830s, the birth of photography.
It is not widely known that Hitler was a vegetarian, and even fewer people know that he was also an animal welfare advocate. Allegedly, the idea to ban bowl-shaped aquariums originated with him, as he believed it was animal cruelty that the fish had no corners to hide in and that the bowl distorted the … Read more
