Making an E-ink ESP32 Credit Card Skimmer Detecting Keychain

My latest project was recently featured on Instructables! In this guide I will show you how to build a low-power credit card skimmer detecting keychain. These skimmers, often found in gas pumps and ATMs, emit a Bluetooth signal that this keychain can detect but that many modern smart phones cannot. There is no need to understand programming and there is no soldering – this guide is suitable for beginners!

Introducing CarbonComponent

I am excited to share that my project, CarbonComponent, was recently selected as a winner of GitLab’s Innovation Pitch Competition! CarbonComponent is a continuous integration/continuous deployment component for GitLab pipelines that allows developers to estimate the carbon emissions caused by visiting their web projects. Using data from The Green Web Foundation it can tell if your web host uses green energy, and will provide you with a Green Webhost badge for your project repository if it does. When a pull request is created, metrics are displayed allowing you to tell at a glance if a change will make your project more carbon intensive. Additionally, it allows developers to offset the emissions from their project through Wren. Check it out! https://devpost.com/software/carboncomponent
