First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register display similar like that. When I first

Universal transmitter to control everything! One transmitter to rule them all. The Devo 10 is a programmable radio transmitter from Walkera. When Deviation is installed with a couple of RF modules, it can almost replace every transmitter for your RTF micro multi-rotors/quadcopters/helicopters and planes. In this video, I show how to mod it with a

Access to medical devices is unequal across the globe, and the COVID-19 pandemic has underscored this fact. During the pandemic the global shortage of ventilators has been especially notable. Access to mechanical ventilation in Low and Middle Income Countries is inadequate. South Sudan, for example, possesses four ventilators in total. Across 84 healthcare facilities in

Using graphic LCD in a project gives it really a good look and flexibility of displaying different characters and shapes. But, the graphic LCDs are quite costly. The NOKIA 3310 LCD provides a really low-cost solution to add a small graphic display into your project and also good for learning purpose. The LCD is SPI bus compatible, saving many pins for other uses.

Here is my home-made kit of ATmega32 microcontroller interfacing. The ATmega32 controller is rich with features like onboard 32kB in-System programmable flash, 1 KB EEPROM, 2KB SRAM, 10bit ADC (8 channel), SPI bus inteface, TWI (compatible with I2C bus) interface, an USART, analog comparator, etc. That’s why I’ve selected it to load my kit with all those features. This M32 card is having an LCD inteface with contrast
