Whether you’re in the lab soldering components or on your laptop running simulations, learning circuits is about blending theory with hands-on practice. RIT’s Circuits Studio Lab offers real-world ...

Soldering to a PC board can be tricky: Too much heat can make the copper trace lift right off the board substrate. Use a soldering pencil rated at 15-25 watts, no more. (Watch the video; story ...

Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors Q1 ...

The basic metallurgy of solder. How to make a solder joint. How to repair a circuit board. The vintageTEK museum is a geek’s paradise to tour if visiting the Portland, Oregon area. The museum has ...

Electronics components are steadily moving away from through hole parts to using surface mount technology (SMT) exclusively. While the small size of the SMT components can be intimidating, with a ...

When writing my last article, I came upon something I thought had been lost to the seven seas of YouTube: the old-school “Basic Soldering Lesson” series from Pace Worldwide. This nine-episode-long ...

Any robot that moves needs actuators—motors that move parts of the robot around. While robot actuators have been around since the dawn of machines, they have some issues. For one, it is very difficult ...

Hand-soldering a few PC boards is surprisingly popular given how many components come only in surface-mount technology (SMT) packages these days, especially when you consider just how small some of ...
