Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

A solar day lamp is a simple, inexpensive device for bringing “daylight” to dark interior spaces whenever the sun is shining. This article provides complete instructions for designing lamps using both ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

In the late 1990s I was working for a company that manufactures sub-systems for tramways, subways and light rail car manufacturers. One day my boss tells me that one of our inverters, a 5 kW DC to ...

This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...
