I have been looking for a good stereo amplifier circuit diagram for a long time. I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or […]
I learned about the basic electronic components by going to the library and reading books. I was just starting out. And I felt like a lot of the books explained everything in a difficult way. In this article, I will give you a simple overview, with an explanation of the basic electronic components – what […]
In this short and simple tutorial I am going to walk you through how to use the Eagle autorouter with net classes. The net classes feature lets you select different widths for each net. This is useful if you for example want your power traces to be thicker than your signal traces. In this example we’ll set up a new net class for our ground net. And we’ll set the default width for all the other nets.
Here is a really cool and huuuge recycling machine we built for a music festival in 2010. It is an interactive recycling station. The idea was to make recycling fun. When you put garbage in it, the machine detects it and moves the ball on the left side one step up. When the ball has […]
There are so many cool things you can make with mini radar circuits. I thought I’d share some examples from my time in the radar business. Then end with a few examples of where you can get a hold of a radar circuit. Just to be clear: A radar is a sensor that uses electromagnetic […]
Tonight I will broadcast the 3rd and final part of the Arduino Shield Webinar – How to create your own Arduino Shield.
