“This project started off innocently enough; I just wanted to add one permanent light to my bicycle for when I ride at night. The idea snowballed from there and I now have a super fancy bicycle safety light system using …
“Tiny module is a PWM Solenoids and Valves driver using Texas instrument’s DRV103 low-side DMOS power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, motors …
“Some 3 years ago I started building my own wireless sensor network at home. The technology I used at the moment has proven to be the right choice, mostly because it is flexible and modular. MQTT is the keystone of …
“Love musical singing Tesla coils ,but don’t know how to build them or it’s too costly ! ,Well Today we’re going to make a mini singing Tesla coil using very common modular parts ,which you can buy online …
“Ultrasonic sensors for Blind are projects that use ultrasonic sensor HC-SR04 to detect objects or obstacles ahead. When detect objects or obstacles nearby, the device will emit a buzzer sound and movement vibrator.”
“While most of my microcontroller designs run on 3.3 volts there is still the ocasional 5 volt design. Or I do something with an Arduino. So the need may arise to interface between logic working at different voltage levels …
“Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to matter and distributed effects need to be taken into account. VNA can be used …
“This project is designed to provide symmetrical output unregulated, high voltage, high current for your demanding needs. Right choice for Audio Amplifiers, Power Drivers, Motor Drivers.”
“For our final technical project we decided to build an electric go kart using commonly available components. The requirements were to implement project management principles, hardware, and software design. The project build time was about 3 months, but the research …
“Hi! With this instructable , you can dose a desired amount of water. The system can work in mL and L. We will use an Arduino UNO, a flow meter to count the amount of water, a LCD to show the …
