A Zero Current Switch for Inductive Loads

A Zero Current Switch for Inductive Loads
Relays or contactors are often used to switch AC powered inductive loads such as motors, valves or electro magnets. When the device is switched off an arc can form across the relay contacts as they open. This leads to premature relay failure if measures are not taken to suppress the spark.

Weekend DIY electronics projects! Talking colorimeter, gamma ray measurement, and more

If you can't see this message properly, view it in your browser. May 3, 2024 | #589    Measure Gamma Rays with a Photodiode: Radiation Detector Using a BPW34 The first device that springs to mind when thinking about measuring radioactivity is the Geiger-Müller tube. However, these counter tubes can be difficult to find and expensive; and, even if you do manage to get hold of one, you will still need to find a way to generate its operating voltage of several hundred volts. It is less well known that even a humble photodiode such as the BPW34 can be used to detect X-rays and gamma radiation.   more...     The Andonstar AD210, an Affordable Digital Microscope with a 10.1" Display The Andonstar AD210 is an entry-level model digital microscope with a large 10.1...

Without this, you won't learn electronics

By
One thing I'd like to learn (or to become better at) is: The practice of silencing my thoughts for a short period. Also called meditation. What does that have to do with electronics? It reduces stress and makes me more focused on the task at hand. So I can build more circuits, faster . At least in theory. ​ The problem is that I don't practice it. So naturally, I don't get the benefit of it. I recently asked my former meditation teacher for advice. He asked me back: "What's holding you back?" "I don't have enough time," I started typing (this was on Facebook Messenger). Then I deleted it because I realized that I could do it in as little as 5 minutes per day. I tried again: "I don't know what to do." But I had to delete this too because I had all the notes from the class that showed me exactly what to do. Then I tried: "I guess I don't have the motivation?" But again, I realized t...
