Lumileds has added news LEDs to its Luxeon IR Domed Line with a significant increase in both DC and pulse drive current–up to 1.5A and 5.0A, respectively. The new emitters deliver radiant power of 1350mW at 850nm wavelength (slightly visible) or 1450mW at 940nm (invisible or covert IR). These new IR LEDs are engineered to […]

Arduino ESPWroom02 Breakout Board
Hey, what’s up, everyone? So here’s something useful: a custom breakout board for using the ESPWROOM02U module for tinkering and testing. The ESP-WROOM-02U Breakout Board is an ESP8266EX-based microcontroller that offers the same features as its predecessor, the ESP Series, but is way smaller, making it suitable for implementing into a badge or wearable project. […]
3D Printed EMG Prosthetic Hand
If you’ve ever looked at prices for prosthetic hand, you may have noticed that they can cost upwards of $5000, with more advanced myoelectric controlled arms priced at over $20,000. Such prices are not ideal considering that over 80 percent of amputees are from developing countries where access to prosthetic limbs is limited by lack […]
Making a Smart BLE Receiver for My Dumb Garage Door
My garage door comes with a motor and a 433MHz remote that I don’t always carry with me because it is quite bulky and in the way. Because of that, sometimes when I am in front of it and I want to open it, I had to go inside and press the trigger switch that […]
IoT Using ESP8266-01 and Arduino
Ever asked how to control any device from any place in the world? In this tutorial, we’ll learn how to control things wirelessly over WiFi. Story Introduction Today, we will build a device that connects to the internet and allow the user to control his/her home remotely over wifi. We will use the Arduino board(any […]
How to Build a Midbar ESP8266 Version
A while ago, I made the ESP32 version of Midbar which later evolved into a multi-user Cipherbox. While developing the Cipherbox, I realized that even the Lite version of it might be too expensive and too redundant for some people, so I “resurrected” the single-user Midbar project and made an ESP8266 version of it. The purpose of Midbar is to […]
Arduino Robot With PS2 Controller (PlayStation 2 Joystick)
In this tutorial, I’ll show you how to use a wireless PlayStation 2 (PS2) controller and an Arduino Uno pilot a robotic tank. Story An Arduino Uno board was used at the core of this project. It receives commands from the wireless controller and sets the speed of the motors. Other development boards might also […]
Redesigning the RA-02 Breakout board module
Story The RA-02 Breakout module includes level converters The RA-02 Breakout Module is designed to be beginner-friendly and compatible with breadboards. Many of them may possess one or more RA-02 Breakout modules. For those who do, they are undoubtedly aware of the challenges associated with using this specific breakout module. The RA-02 module is an […]
Arduino Project Challenge: Exploring Sensor Readings and Component Control
HW9 – Arduino The Task: In our Arduino project challenge, we were free to create anything of our liking, with the only requirement being that the circuit must either read a sensor or control an active component. During a class session, a practice example was demonstrated, involving a humidity sensor, LED, potentiometer, and LCD screen. […]
[Password Box] Arduino One Touch Password Input (USB Keyboard Hack)
Today is the world of internet social. We have many social platform Email, Facebook, Instagrams, Twitter, Instructables and etc.For security issue we should not use the same password for these platform and some platform enforce us to create password that difficult to remember. It is better to write it to your notebook but some people […]
