Multi-layer ceramic capacitors (MLCCs) are so ubiquitous that you see them on almost every printed circuit board. Engineers and supply chain managers often ask whether polymer electrolytic capacitors can replace MLCCs. The replacement could be because of availability, or an application cannot tolerate the extreme capacitance loss with MLCC’s DC Bias Effect. This video demonstrates what happens when you replace MLCCs with Polymer Tantalum (KO-CAP) capacitors.
Experience comparing DIY and Turnkey PCB assembly with the Bald SENSE project. This journey started almost four years ago. Thanks to a collaboration with MacroFab, I am finally collecting valuable environmental data with my custom Feather Wing.
I dive into Pico Technology’s latest PicoScope oscilloscope software, PicoScope 7. Using a PicoScope 2000A (from the element14 Community), James walks through key measurements and demonstrations using the built-in arbitrary waveform generator. He explores new functionalities in PicoScope 7, such as the improved UI, a unique feature called DeepMeasure, and decoding I3C traffic.
The Apple II’s ROM has the 8th bit set for all of its ASCII strings. This convention makes it difficult to search the ROM for hex strings quickly. This Python script takes an ASCII string and returns the HEX string with (and without) the 8th bit set.
