Mini Portable Server From An Old Bitcoin Miner

Mini Portable Server From An Old Bitcoin Miner

In this post, I will document the build process for my mini portable server made from an old Bitcoin miner case and an Orange Pi Zero Plus. One day I was looking through my SBCs parts bin and saw the Orange Pi Zero Plus board(still in its packaging) I had bought many years ago but never used. I got the idea to make a small portable server that could maybe run an MQTT broker, act as an AP, run a web server, etc.

DIY Current Clamp Meter

DIY Clamp Current Meter

In this post, I will show you the contactless clamp power meter I made. I used a readily available SCT-013 current transformer clamp. The great thing about this is that you can measure the current flowing through a wire without having to put an amp meter in series with the load and source. This means you also don’t have to expose yourself to a potentially dangerous voltage.


ESP32/8266 Over The Air Updates (OTA)

In this post, I’ll show you how to do OTA(over the air updates) to your ESP32/ESP8266. This means that you don’t have to connect your ESP board to your PC by cable and can instead push firmware updates wirelessly over the network(as long as you are connected to the same network). The process of uploading the firmware remains almost the same. The only difference is you have to select a network port under Tools -> Port -> Network Ports instead of a COM port.

Visual Studio on localhost

Test Local Website on Smartphone While Developing In Visual Studio

In this post, I will show you how to access a local website running on localhost(Windows). Specifically, I will show you how to do this for Visual Studio when you are running/debugging your web app/server during development.

This can be very useful for checking if your website works properly on mobile and allows other people(within your network, unless you port forward) to test your site without having to deploy your site on some remote dev./test server.

GDS Viewer

Online GDS File Viewer

In this post, I’ll talk about the online GDS File Viewer/Editor I made(or I’m making as it’s still a work in progress). For now, I will make the development version of the app available online so people can find it and test it. Eventually, I will post the code on Github but first I want to add some more features, refactor the code and maybe write some unit tests.

C# Code Snippets Bitwise Operators

C# Bitwise Operators

In this code snippet, we will take a look at bitwise operators in C#. Bitwise operators can be used to manipulate individual bits of a variable. These operations can be quite cryptic and hard to understand compared to regular code. So only use it when it makes sense(for example bit masking) and don’t prematurely optimize your code. In C# we can use enums in conjunction with the Flags attribute to do bitmasking. This gives us cleaner and more readable code.

C# Code Snippets Pattern matching

C# Pattern Matching

In this code snippet, we will take a look at pattern matching in C#. Pattern matching is simply testing if an expression matches certain criteria. For example, Regex often times gets used for more complex pattern matching of strings.
