[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking ...

Read more Test Ideas and Design Ideas here. As ICs increase in complexity and decrease in size, their pin counts drop or, at best, remain constant. The result: a need for pin-saving measures like ...

This is a throw-together project using junk box parts that can be useful whenever an interesting-looking waveform is needed for a demonstration or for the beginnings of a video test generator or curve ...

Direct-current generators, especially those based on the Schottky contacts between conductive polymers and metal electrodes, are efficient in converting mechanical stimuli into electrical energy. In ...

Recently, piezoelectric and triboelectric energy harvesting devices have been developed to convert mechanical energy into electrical energy. Especially, it is well known that triboelectric ...
