🎛 20 Cool Raspberry Pi Zero Cases to 3D Print
Small article with a list of different 3D models of cases for your Raspberry Pi Zero board, the links to 3D files with models are included.
"The Raspberry Pi Zero is a tinkerer’s dream! This tiny single-board computer features a 1-GHz processor, 512 MB of RAM, and on-board Wi-Fi and Bluetooth, all for only $10.
To reach that price point, the Pi comes fairly bare-bones; it only includes the circuit board itself, with no accessories. As such, the board can be fairly fragile, so having a case for your Pi is important. To that end, we’ve gathered a list of our top 20 Raspberry Pi Zero cases. Let’s take a look!"

🔬 How To Get Started in Soldering
Becoming a master of the melting and gluing powers of solder can help you start building your own electronics.
For hobbyists who want to create their own electronics from scratch, there comes a time in every project when two metal surfaces must merge. Solder, which changes from a flexible solid to a liquid, then back to a solid in seconds, is the magical metal glue that makes this happen.
Solder can also be a frustrating mess. For reasons both aesthetic and functional, you'll want to learn how to work with it cleanly and neatly, because sloppy soldering means your project might not work.
The following article will get you acquainted with basic terms of electronics, soldering and give you a good grounding to start working on your own electrical projects.

🗜 3D-printed Variable Capacitor
Have you ever stuck in the middle of a project trying to find out the perfect size capacitor for your project? If yes then this is the project for you!
To make a variable capacitor we need to vary some parameters upon which the capacitance depends: the capacitance value depends on the area and the distance been the parallel plates. We will change the area of interaction of two parallel plates to vary the capacitance.
Our solution will consist of two cylindrical aluminum foils whose area of interaction will be controlled by the rotation of a threaded rod. It will provide precision control over the range of the capacitance.

💡 Data Integrity Critical to Embedded Systems
How do you validate sensor and communication data to ensure data integrity in embedded systems?
▫️ 1. At least use a parity check
Parity is a data integrity mechanism that looks at the number of ones in a data stream and will then adjust a parity bit to make the overall number of ones either odd or even. Parity works well for detecting single bit flips. However, if two or more bits flip, it’s possible the error would go undetected. For that case, a more robust technique is required.
▫️ 2. Use a checksum
A checksum is an algorithm that is designed to detect errors that occur naturally or randomly in a dataset. A checksum is often calculated over a set of data which then results in the checksum for the data.
▫️ 3. Use a cyclical redundancy check (CRC)
A CRC is a checksum that uses polynomial division to calculate the checksum. CRC is so effective that many microcontroller vendors will include a hardware-based CRC calculator.

💵 IoT Wallet (smart 3D-printed Wallet With Firebeetle ESP32, Arduino IDE and Google Spreadsheet)
So how do you track assets and know their current value? You can work with some spreadsheets and update them regularly. Or you can create your own gadget to check these values for you: an IoT wallet!
This spreadsheet is accessible from an ESP32 using and Wi-Fi connection, and a summary is shown on an OLED display. A 3D printer was used to create a wallet, in which I embedded some electronic components to create my first IoT wallet prototype.
There are several ways to use this tutorial. You can use it to:
▫️ Learn how to track and update your asset values for a particular currency using a Google spreadsheet;
▫️ Program an ESP32 using the Arduino IDE;
▫️ Read values from a Google spreadsheet using an ESP32 device;
▫️ Practice your electronics and soldering skills, etc;
