“The project presented here is a high common-mode current sense amplifier with two high-speed comparators to detect out-of-range current conditions. The comparators are configured to detect and respond to dual over current conditions. These devices feature an adjustable limit threshold …
“I present a method to continuously measure wind speed and wind direction as part of a custom weather station project. This article is part of a series discussing methods for adding sensing capabilities to a DIY telescoping pole project made …
“MIDI controller-filter-router, sound generator, available in kit or fully assembled. Designed by pangrus’ electro acoustic lab in Italy. I got my hands on REYAX Lora modules, and in this tutorial, we will configure these modules to communicate with each other …
“The project presented here is a bipolar stepper motor driver. It is based on BD63731EFV chip which is a low-consumption driver that is driven by a PWM signal. The power supply voltage of the project is 8 to 28V DC …
“The project presented here is capable of supplying 400mA of current from a 3.7V Li-Ion/Li-Po Battery input with a 5V output. The converter has an internal soft start and internal frequency compensation features. The project is built using …
“MC3362 and ADF4351 based, modularized, NFM receiver. This receiver is designed to listen to the 2m band amateur radio conversations. This project is about MC3362and ADF4351based modularized, 2-meter narrow band FM receiver. In this design, the receiver splits into three …
“This is a simple ne555 timer IC based multi vibrator breathing effect . The LED blinks like we breathe we can control the breathing time using potentiometer on board. It works on 5 volts DC to 9 volts DC. The working …
“The board presented here is a preamplifier for contact microphones that are used for amplifying the sound of musical instruments which do not contain electrical pickups, such as guitar and violins. Most contact microphones use a piezo element to convert …
