Soldering is a crucial process in electronics assembly and repair. But what happens when you open up that old roll of solder wire and find it’s a bit crusty? Does solder expire? The short answer is yes, solder does have a shelf life. While pure metals like tin and lead don’t technically pass, solder’s flux core and alloying elements can degrade over time. An old roll of solder may still melt, but it can cause cold joints, poor electrical connections, and other issues. So before you fire up your soldering iron for your next project, it’s worth examining if that solder is still up to par. Let’s ..read more

Capacitors – those tiny components that quietly do their job in circuits, big and small. Yet, peek inside your device, and you’ll find capacitors of many types and sizes. Film and ceramic capacitors are two of the most common. Though similar in function, they have key differences that make each suitable for specific applications—journey into the miniature world of capacitance to discover what sets film and ceramic capacitors apart. We’ll compare their materials, performance, and uses so you can decide which type is the right fit for your next circuit design. Let’s delve deeper into the capacit ..read more

Uh oh, is your phone or laptop battery starting to bubble up like a fresh can of soda? That hissing and swelling sensation is never a good sign. Battery bubbling can indicate dangerous gases building up inside, threatening to leak or even explode. But before you panic, take a deep breath and assess the situation calmly. Though it may look alarming, some gentle bubbling is normal, especially in older batteries. The key is knowing when it’s gone too far. With the proper precautions, you can take control before things get messy. In this article, we’ll cover what causes battery bubbling, how to te ..read more

A cloud of steam hisses from under the hood as you pull over to the side of the road. Popping open the lid reveals the culprit – a small leak in one of the joints of your radiator. The good news is this doesn’t have to mean an expensive trip to the mechanic. With the right tools and techniques, repairing a leaking radiator by soldering it yourself can be a satisfying DIY project that saves you time and money. While soldering a radiator may sound intimidating, understanding the basic steps and equipping yourself with the necessary supplies can make you successful. This straightforward repair co ..read more

Shoddy craftsmanship shows its true colors under pressure. When constructing a circuit board, the integrity of solder joints is crucial. Though imperfections may seem minor at first glance, these defects threaten to undermine the entire operation. Just as a faulty foundation compromises a building’s structural soundness, cold solder joints represent cracks in the circuitry that can lead to system failure. Before the pressure mounts, examining the solder bonds closely and shoring up any weaknesses is wise. Doing so now can prevent a catastrophic collapse later on. Let us shed light on these fro ..read more

As technology advances, makers and engineers choose between programmable logic controllers (PLCs) and microcontroller platforms like Arduino for automation and control projects. Both offer digital programmability but have key differences that make each better suited for certain applications. When picking the right solution for your needs, it’s important to weigh factors like complexity, flexibility, cost, and ease of use. To help decide between PLC or Arduino, it’s valuable to understand the pros and cons of each. This guide will compare the critical differences between the two popular options ..read more

Light sensors come in many forms, but two of the most common are the phototransistor and the photoresistor. Though they both detect light levels, their inner workings differ significantly. The phototransistor relies on a semiconductor junction to control current flow, almost like a standard transistor but activated by light instead of electric potential. Meanwhile, the photoresistor changes its resistance according to light intensity. Both have their advantages and applications. This article will explore the key differences between these two popular light sensors, from construction to performa ..read more
