Nebra Helium Hotspot Miner

I have been hearing about Helium for a while now and it seems to be gaining traction with n number of gateways now scattered throughout the world it is starting to become a viable solution to providing an IoT backend. The incentive to gateway owners being the HNT cryptocurrency that is mined when they provide… Continue reading Nebra Helium Hotspot Miner

Adaptive Beamforming with LMS

In a traditional beamforming application, the goal is to design an antenna whose radiation pattern points in a specific direction instead of just being purely isotropic. This directionality can be used as spatial filtering and is achieved in many different ways. One way is to use a directional antenna, such as a dish whose directionality… Continue reading Adaptive Beamforming with LMS

Magnetic Communications

While playing with the magnetometer sensor on the Arduino for my DIY smart bike project I had an idea that I might be able to use a magnetometer as a crude communications receiver. The question being, Can we transmit data, by modulating a magnetic field, to a computer using a magnetometer sensor as a receiver,… Continue reading Magnetic Communications

Getting Started with the Ambasat-1

The Ambasat-1 is an open-source Sprite Class Satalite that you can assemble, program, and have launched into space! Your very own satellite in space! When most people hear the word satellite they think of multi-million dollar devices that are way out of the reach of your average maker. But the cost of satellites and their… Continue reading Getting Started with the Ambasat-1

Python Color Scope

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

Automatic Sensor Dust Removal

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

Using Jupyter Lab for Python Projects

I was looking into using Jupiter Notebooks for a project when I found the JupyterLab software, it is a tool that looks to combine your workflow into a single place. This allows you to open, and interact with, Jupyter Notebooks, text editors, terminals, and many others. You can download it for your system from the… Continue reading Using Jupyter Lab for Python Projects

Python Digital Phosphor Display with DearPyGui

The goal of the Intensity graded FFT project did not initially include a GUI aspect as I felt that the GNURadio Fosphor module provides an amazing spectrum display, but as I was programming I came across an interesting library that claims to provide a simple but powerful python GUI experience. https://teaandtechtime.com/python-intensity-graded-fft-plots/ Previous post on Intensity… Continue reading Python Digital Phosphor Display with DearPyGui

Looking Back On Hackaday Supercon 2019

I learned about the Hackaday Supercon a few days before Supercon 2018 was starting so I, unfortunately, missed out on tickets. So after seeing all the amazing talks posted online, and hearing about the amazing badge and the multi-day hacking that took place, I made sure I did not miss it in 2019. And wow… Continue reading Looking Back On Hackaday Supercon 2019
