Crowbar Circuit Using TRIAC and TL431 Precision Programmable Reference
https://www.electronics-lab.com/project/crowbar-circuit-using-triac-and-tl431-precision-programmable-reference/
This Crowbar project can be used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuit connected to the power supply. It operates by putting a short circuit and fuse blow across the voltage output, like dropping a crowbar across the output terminals of the power supply. The circuit […]

Stepdown DC-DC Converter with Current Limit
https://www.electronics-lab.com/project/stepdown-dc-dc-converter-with-current-limit/
The step-down DC-DC Converter project presented here provides 3.3V @ 1A output from an input range of 8V to 36V DC. The adjustable current limit is an important feature of the project, which prevents the device from accidental output short circuits avoiding excessive load damage. The internal limiting current (latched function) has a typical value […]
Step Up DC-DC Converter – 24V/10mA Output from 12V DC Input – Compatible to TO220 LDO
https://www.electronics-lab.com/project/step-up-dc-dc-converter-24v-10ma-output-from-12v-dc-input-compatible-to-to220-ldo/
The project demonstrated here is a small-size solution, high-efficiency, low-cost, and low-EMI step-up DC/DC module for LDO regulator replacement. This small size module helps save on solution size and cost while also eliminating the need for a heatsink. The module takes up the same amount of space as a TO-220 package and is pin-to-pin compatible […]
2 Channel Smart Dual Coil Latching Relay Board – 2 Channel Bistable Relay Module
https://www.electronics-lab.com/project/2-channel-smart-dual-coil-latching-relay-board-2-channel-bistable-relay-module/
This is a Smart Dual Coil Latching Relay that can control the ON/OFF power of a device by applying a short voltage pulse to Input 1 and Input 2. This project is helpful in low-power applications since the coil is not powered all the time, it only requires a short voltage pulse. Relay Coil also […]
RISC-V: Open Standard Instruction Set Architecture on Open Standard Module (OSM)
https://www.electronics-lab.com/risc-v-open-standard-instruction-set-architecture-on-open-standard-module-osm/
The two main CPU architectures commonly used in PCs, laptops, cellphones, and embedded devices around the world are x86 and ARM. These architectural designs demand licenses or royalties and are proprietary. They do not provide continual support, and they prevent businesses from creating their own ISAs (Instruction Set Architectures). According to researchers, compilers in these […]
Arduino Cloud gets a feature called phone device to enable a quick out-of-the-box experience with the platform
https://www.electronics-lab.com/arduino-cloud-gets-a-feature-called-phone-device-to-enable-a-quick-out-of-the-box-experience-with-the-platform/
Arduino released a cloud platform, Arduino Cloud, that would enable developers and hobbyists to build smart connected projects based on a wide range of electronic hardware products, such as Arduino, ESP32, and even ESP8266.
