Internet-of-Things Power Meter
https://www.electronics-lab.com/internet-of-things-power-meter/
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 usage. Modern power meters have a LED blinking every time a Watt […]
DC Motor Speed and Direction Controller
https://www.electronics-lab.com/dc-motor-speed-and-direction-controller/
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 protections. Specifications Supply 5 to 12 V Inhibit facility/enable […]

Current bending yields low-power magnetic memory
https://www.electronics-lab.com/current-bending-yields-low-power-magnetic-memory/
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 instead of stored charge, MRAM is nonvolatile, which means that the stored data […]

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 with a 6V to 58V (60Vmax) input voltage range and adjustable load current control with […]
Teardown, Repair & Experiments with the Anritsu 37347A 20GHz Vector Network Analyzer
https://www.electronics-lab.com/teardown-repair-experiments-with-the-anritsu-37347a-20ghz-vector-network-analyzer/
In this episode Shahriar repairs an Anritsu 37347A 20GHz Two-Port Network Analyzer. The unit does not boot up and as a result its internal state is unknown. The boot fault is traced to a bad RTC module which has a built-in integrated battery. A replacement unit is located which allows the unit to fully boot. […]
5V to 12V @400mA Boost Converter
https://www.electronics-lab.com/project/5v-12v-400ma-boost-converter/
The circuit presented here is about a boost converter based on LM2698. It is a PWM boost converter from Texas instruments. LM2698 can also be used as a flyback converter. The current mode architecture is a special feature of LM2698, which provides superior line and load regulation. This circuit is capable of a supplying a […]
Chemoelectronics: Nanoparticle Diodes and Devices That Work When Wet
https://www.electronics-lab.com/chemoelectronics-nanoparticle-diodes-and-devices-that-work-when-wet/
Dexter Johnson has a writeup about flexible, water-loving logic circuits and sensors without the need of semiconductors. They constructed the chemoelectronic devices by coating gold nanoparticles with any of four types of organic molecules called ligands. Each ligand produces a different, charge-related effect when put in water or a humid environment. One dissolved, releasing a postive […]
BOM/Component manager for KiCad
https://www.electronics-lab.com/bomcomponent-manager-for-kicad/
Jeff Ciesielski has published a component manager for KiCad layout software. The goal of this app is to ease the bom management burden on designers who choose to use Kicad for their layout and schematic capture needs, allowing for faster, easier data entry, and to provide a part database for re-use in future designs. BOM/Component […]
Open-Source SWD Programming Adapter
https://www.electronics-lab.com/open-source-swd-programming-adapter/
Ethan Zonca has designed a programming adapter for use with STM32 programmer. After making the switch from AVR to STM32 microcontrollers, I redesigned my old 6-pin ICSP pogo-programming adapter for SWD. The new design allows programming with pogo pins or a small pin header soldered to the pogo pads for debugging, all with the same […]
