Hobbyist and low-cost antenna design software have been usually limited to basic theoretical calculations based on ideal EM equations that could be done on the back of the hand. It is only recently that full EM simulation has drifted down to the masses in a semi-affordable way. CENOS Antenna Design software is one of the… Continue reading First Look at CENOS Antenna Design Software
What is Aerochrome film? It is an analog film stock that is sensitive to infrared light and uses false-color reversal to express infrared light as a visible color. Infrared (IR) light is invisible to the human eye but is all around us and be felt as heat. All objects in the universe emit some level… Continue reading Emulating Kodak Aerochrome Infrared Film with Python Image Processing
The idea behind the Helium project really struck me as a unique intersection of radios, decentralization, and cryptocurrency. And as The Peoples Network keeps growing I saw a need to somehow quantify how well your hotspot is doing at its current position compared to the other hotspots around you. This is because the amount of… Continue reading Helium Hotspot Performance Analysis With Hotspots Health
Want to build a blog, use WordPress, want to build a professional or web store use SquareSpace, want to build software as a service use Bubble. There are so many web-building tools out there that help people create professional and responsive websites for businesses, internal tools, blogs, or just about anything else you can dream… Continue reading Building A Custom Dashboard with Bubble.io
As part of the GNURadio Conference 2021, the Radio Resilience Competition created a custom competition just for the conference. This is similar to the Capture the Flag (CTF) that has been a mainstay of the GRCon. The cool thing about this competition is that it was not just for bragging rites but real prizes! The… Continue reading Radio Resilience Competition at GRCon21
It's that time of year again! the GNURadio Conference is back, in-person and virtual as a hybrid conference this year! This conference is centered around the GNURadio software and its different aspects and community. Focusing on software-defined radio processing and its applications. Each year the conference is held at a different location in the US,… Continue reading GNURadio GRCon 2021
Ignoring whether NFTs or Non-Fungible Tokens are useful or valuable it is an emerging market that combines art and code so why not try making your own with python. The process of creating an NFT will not be done in python only the image generation. I decided to create some pixel art NFTs mostly because… Continue reading NFT Pixel Art Generated with Python
With any successful wireless system, you want to have some theoretical basis that your transmitted information can reach its intended receiver with enough power to be deciphered correctly. This is the basic idea behind a link budget where you compile information about your radio hardware and setup such as transmitter power, receiver sensitivity, antenna gain,… Continue reading Simulating Helium with HotspotRF
Doing color correction in a program like Divinci Resolve we can see these interesting plots based on your loaded image, like the one below. These are called color scopes, they are primarily used to identify the pixel colors as you traverse the image from left to right. They are useful for photographers and videographers to… Continue reading Python Color Scope
Interchangeable lens cameras are amazing feats of engineering, but as photographers trying to capture that perfect image you are sometimes saddened to realize that there are big black smudges scattered throughout your digital image. These black spots or smudges are caused by small specs of dust and debris that settle on the image sensor and… Continue reading Automatic Sensor Dust Removal
