Another day, another dodgy device. This time, it was the continuity beeper on my second-best DMM. Being bored with just open/short indications, I pondered making something a little more informative. Perhaps it could have an input stage to amplify ...
Ages ago, humankind crawled out of the primordial analog ooze and began to do digital. They soon noticed and quantified a fundamental need to interconnect their new quantized numerical novelties with the classic continuum of the ancestral ...
A predominant failure mechanism for production pc boards is shorted traces. Finding hidden shorts is often time-consuming and frustrating. Typical techniques of cutting traces, lifting pads, and “blowing” shorts are, at best, ...

EDN Design Ideas (DI) published a design of mine in May of 2025 for a passive two-way current mirror topology ( Ref. 1 ) that, in analogy to optical two-way mirrors, can reflect or transmit. That design comprises just two BJTs and one diode. But ...
What’s new Texas Instruments is enhancing the next generation of digital lithography with the introduction of the DLP991UUV digital micromirror device (DMD), the company’s highest resolution direct imaging solution to date. With 8.9 ...
DAC control (via PWM or other source) of regulators is a popular design topic here in editor Aalyia Shaukat’s Design Ideas (DIs) corner. There’s even a special aspect of this subject that frequently provokes enthusiastic and ...
Electronic systems must often isolate their inputs or outputs from the main reference common (ground). Various conditions can make necessary such galvanic isolation: the type of input sensor or driven actuator, safety considerations for medical ...
