In this tutorial, we will see how to write and read files in C#. In this example, I will use a console application. If you want to know how to open a file dialog and select/create a file in a WFA application see this post. For WPF applications see this post.
In this post, I will show my DIY ZVS flyback driver high voltage generator. The ZVS driver can actually also be used to make an induction heater. But in this case, I will use it to drive a flyback transformer to make high voltage. In the video below you can see a demonstration of the arcs produced by the transformer and a jacobs leader.
In this post, I will show my DIY quiet air compressor. I took the compressor from an old fridge and used an old whipped cream dispenser as an air tank. The compressor is very quiet and can thus be kept indoors(under my table in fact). The air capacity isn’t the greatest but it’s good enough for my needs(doing some pneumatics experiments, solder dispenser, …). The air pressure, however, can easily get up to 8 bar(around 120 psi). In addition to compressed air, you also get a vacuum line. You could, for example, use that for making a vacuum chamber or a vacuum pick up tool.
In this post, I will show you how to fix the scaling issues in Quartus if you are using a higher resolution screen. This also works for any other programs affected by the issue of not properly scaling the UI for the high resolution.
In this post, I will show my DIY portable power supply. The PSU uses the DPS3003 module. This module is rated for voltages from 0-32V and currents from 0-3A. You can get other models with higher or lower voltage/current ratings. The input voltage, however, must be in the range of 6-40V and your maximum output voltage is limited to your input voltage. In my case, the battery provides around 16V to the input so the output voltage can’t go higher than that.
In this post, I will show my DIY power/power factor meter. The module itself was bought(of course) I just put it in an enclosure and added some cables to make measurements easier. This way I have a handy and cheap tool for measuring the power and power factor of any device that I connect to it. This thing is no professional instrument with great accuracy but it’s good enough for doing some basic measurements.
In this tutorial, you will learn how to output video from an Arduino and display it on a TV. Here we will specifically, see how to output an image. If you would like to know how to make the adapter or know more about the other functions available(outputting text, shapes, pixels) in the TVout library see this post.
In this tutorial, you will learn how to output video from an Arduino and display it on a TV. We will make a board/cable adapter that will connect the Arduino to the TV through the RCA input. Then we’ll look at some of the functions available to us in the TVout library and use them to output something to the screen.
In this tutorial, we will see the difference between method hiding and overriding in C#. The difference between method hiding and method overriding becomes evident when a class object is used polymorphically. The child version of the method gets called only when the method is overridden. If the method is hidden(new keyword) the parent version of the method gets called. Meanwhile, if we don’t call a method polymorphically the new keyword will act in the same way as the override keyword does and hide the original parent implementation of the method.
In this tutorial, we will take a look at the using keyword in C#. The using keyword can be used as a directive to include a namespace or it can be used as a statement. Using it as a statement the using keyword ensures that the dispose() method gets called even if an exception occurs.
