In this video, Kerry Wong took apart a 8 to 10 GHz microwave RF isolator and did some measurements. High resolution teardown pictures here. RF Isolator: Teardown and Experiments -...

Zach Fredin and Joe Burdo has designed an electronic neuron simulator to help educate students of neuroscience. NeuroBytes are tabletop electronic neuron simulators designed to help students understand basic neuroscience concepts. The platform consists of modular elements that can be...

Vicente Jiménez has published a new project. It's a circuit probe that gives an indication when a node is floating or driven logic high or logic low and can also be used as a continuity tester. He writes: Sometimes you need to check one circuit and test some of its nodes. Usually a...

Dilshan Jayakody has build a low voltage power supply that is able to provide four outputs:  1.5V, 1.8V, 2.5V and 3.3V. This power supply can be used to power low voltage mcus, CPLDs and analog ICs. He writes: In this post we introduce simple and flexible, regulated low voltage...

This is a simple, cheap, easy to build IoT Power Meter that provides accurate statistics on household power consumption: The Internet-of-Things Power Meter (IPM) is a device fixed on top of the regular household power meter that provides detailed information about the electricity...

DC Motor Speed and direction controller project based on L293D H-Bridge and 555 Timer IC. 555 Generate PWM and L293D works as output driver. The 293D provides bidirectional drive current up to 600mA a voltage from 5V to 12V. L293D includes the output clamping diodes for...

by Harry Baggen @ elektormagazine.com: Magnetic random-access memory (MRAM) is faster, more efficient and more robust than other data storage media. MRAM stores data by making clever use of electron spin – a sort of gyroscopic property of electrons. Because it used magnetism...

LTM8064 is a step-down DC/DC µModule (micro-module/power module) regulator with a 6V to 58V (60Vmax) input voltage range and adjustable load current control with ±10% accuracy at 7A. Linear Technology introduces the LTM8064, a step-down DC/DC µModule® (power module) regulator...
