When I was in the basement of the house I grew up in and played around with electronics, the transistor was mysterious to me. In the pictures of the circuits I wanted to build – I saw these weird names like BC546 or 2N2222. And when a schematic told me to use the BC546, I […]
A little while ago, a guy emailed me and said he wanted to practice his programming skills and therefore had made a site for comparing prices for circuit boards. I checked it out, and it was
I was sitting in the armchair in the living room and I was maybe 13-14 years old. It was something that me and my dad was talking about that got me thinking. I had heard somewhere that 1’s and 0’s was the foundation of computers, cell phones, TV’s, remote controls, digital watches… And I had […]
A couple of years ago, I bought a robot vacuum cleaner. It would run around our office and clean the floor. It was not very efficient – but it was really cool! Robots are just cool. And I have noticed that a lot of people want to build one. But how do you do that?
In the last email I wrote about how easy it was to measure temperature. But what about distance? How can you make a device that measures the distance to the wall for example? This can be done
In today’s email I wanted to send out a quick tip that I use a lot. As you know, when you are building something with electronics, you need a schematic to follow. It’s like your blueprint for making the circuit work. You can either design this schematic diagram yourself, or you can find one that […]
