What is DIY Electronics? DIY electronics involves building electronic circuits and devices yourself, rather than buying pre-made consumer electronics products. It’s a hands-on way to learn about how electronics work while creating useful and interesting projects. With DIY electronics, the possibilities are endless – you can make anything from a […]

What is DC Voltage? DC voltage refers to the constant, unidirectional flow of electric current in a circuit. Unlike alternating current (AC), which periodically reverses direction, DC current maintains a consistent flow from the positive terminal to the negative terminal of a power source. This steady flow of electrons provides […]

What is a Parallel Circuit? A parallel circuit is a type of electrical circuit where the components are connected in parallel, meaning that the current has multiple paths to flow through. In a parallel circuit, the voltage across each component is the same, but the current flowing through each component […]

Proper PCB Soldering Tools and Setup Having the right tools and setting up your workspace properly is essential for successful PCB soldering. At a minimum, you’ll need: Soldering iron with adjustable temperature control Soldering iron tips in various sizes Solder (lead-free is most common) Brass or conventional sponge for cleaning […]

Overview of the Hx711 Module The Hx711 module is a breakout board for the Avia Semiconductor Hx711 24-bit ADC for weigh scales. It allows you to easily read load cells and scale sensors to measure weight. The module interfaces with microcontrollers like Arduino and Raspberry Pi using just two wires. […]

Introduction to PCB Circuit Boards A Printed Circuit Board (PCB) is a fundamental component in modern electronics. It is a flat board made of insulating materials, such as fiberglass or plastic, with conductive pathways etched or printed onto its surface. These pathways, known as traces, connect various electronic components, such […]

What is a Cold Solder Joint? A cold solder joint is a defective solder connection that occurs when the solder fails to melt and flow properly during the soldering process. This results in a dry, cracked, or incomplete bond between the solder and the surfaces being joined. Cold solder joints […]

What is PCB Assembly? PCB assembly is the process of attaching electronic components to a printed circuit board. The components are placed on the board according to a predetermined design and then soldered to establish electrical connections. The assembLED PCB forms the backbone of the electronic device, enabling it to […]

Introduction to Keyboard PCBs A keyboard PCB (Printed Circuit Board) is the foundation of any custom mechanical keyboard. It serves as the central nervous system, connecting all the components and enabling the keyboard to function properly. Designing and building a keyboard PCB requires a thorough understanding of various factors, including […]

What is Countersinking and Counterboring? Countersinking and counterboring are two techniques used to create recesses in a printed circuit board (PCB) to accommodate the heads of screws or other fasteners. These techniques are essential for ensuring that the fasteners sit flush with the surface of the PCB, preventing any protrusion […]
