The ICON Digital Circuit Tester is a new test light that is available at Harbor Freight. Unlike an old-school device, this light provides a bright red (positive) or green (negative) LED numeric ...

Some MD0657C2-R LED dot matrix displays for not a lot needed a project. The displays are mounted in groups of four on small PCBs, driven by a MAX6952, which are then controlled by a Pi Pico.

A new approach called monolithic synchronous integration enables the direct fabrication of lead-based optoelectronic devices on silicon circuits, promising simpler, cost-effective production of ...

Instead of requiring a dedicated wire for each input or a matrix circuit to scan multiple buttons, the NES controller stored all button states in a shift register and sent them one at a time to ...

This letter describes a synthesis method for wideband bandpass filters (BPFs) that uses an optimized matrix scaling technique for direct circuit implementation. The method commences with constructing ...

The intermodulation (IM) matrix was deduced to express the PIM model of the a uniform microstip line, which was further applied to analyze the more complicated PIM product phenomenon of microstrip ...
