Sometimes you need a little utility device to do a very simple job, and do it well.This one-shot IR helper from [Gregory Sanders] is just that. [Gregory] had a TV that didn’t support automatically turning on when the power was applied. This is frustrating when you like to leave devices switched hard off when not in

Radio Frequency Network Analyzers is one important tool required for testing the frequency response of filters and networks, but as we all know, buying a regular RF test equipment can be quite the expenditure. This was why hobbyist Stephen Merrifield, who after seeing the increased need for more RF testing capabilities as a result of increased awareness of
Vishay Intertechnology, Inc. today introduced a new 30 V n-channel MOSFET half-bridge power stage that combines a high side TrenchFET® MOSFET and low side SkyFET® MOSFET with an integrated Schottky diode in one compact PowerPAIR® 3.3 mm by 3.3 mm package. For power conversion in computing and telecom applications, the Vishay Siliconix SiZF300DT delivers increased power density and
If you’re one of those people who got into building electronics for the purpose of making music, then this Raspberry Pi RP2040-based audio DSP project by [DatanoiseTV] might be of interest. Provided is a FreeRTOS template application for creating Eurorack compatible synthesizers, effects processors, and similar DSP-based audio widgets. The hardware platform has the usual Eurorack connectivity, including MIDI
