John is 1.8 meters (6 feet) tall. And in this email I'm going to put him into a hole to show you what negative voltage means. But first, what does it mean that John is 1.8 m tall? Could you find his height by only looking at his head? No. You have to compare the top of his head to the ground he is standing on to be able to find his height. That John is 1.8 m tall really means that the top of his head is 1.8 m higher than the ground that he stands on. ​ It's the same thing with voltage. You can't say anything about the voltage without comparing it to another point. It's common to define a zero point, or "ground", in a circuit. In a simple battery circuit, the ground point is usually the minus terminal of the battery. So if someone says that "this point is 5V", they usually mean it's 5V compared to ground. ​ What is a negative voltage? Back to John. What if we dig a hole of 1.8 meters, then put John into the hole.

Are you waiting for inspiration to finally learn electronics? Well, wait no longer. I read this quote a while back, but I forgot who wrote it: "I don't believe in inspiration. Inspiration is for amateurs. The rest of us just sit down and do the work." ​ Also, in my old gym there was a similar quote by Michael Jordan: "I've always believed that if you put in the work, the results will follow" ​ Are you putting in the work to learn electronics? By "putting in the work" I mean sitting down and building circuits, not just reading about them. It's nice to read about a project or circuit, understand the explanations, and think "I could do that". However, sitting down and actually doing the project, so that you later can say "I did that" - that's what it takes to learn electronics! Start with small and simple projects. Then progress from there. ​ Keep On Soldering! Oyvind @ build-electronic-circuits

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″ display.
