I stood in stunned silence at the smoke billowing up from the hardware on the workbench. Just moments before, it had been operating as expected, before self-destructing with a sound that can only be compared with a gunshot. The failure of the hardware under test had an unexpected consequence: the computer that had been using […]

Converting from Eagle to KiCad. Quick Introduction Video Recommended video player Firefox 56.0+ with VLC video player plugin The following 5 ulp (eagle user script file) and one ulp include file, work together or stand alone to convert Eagle sch/pcb version 6.xx*(7.xx-8.xx maybe?)* file(s) and any version of Eagle lib(lbr) to KiCad sch/pcb and lib/mod

In my previous Instructable I have described how to plug the ESP-01 module into a breadboard. This is just the first step to make a cheap Arduino WiFi shield using the ESP8266 module. With few more electronic components and the WiFiEsp library you can build it for less that 10 USD. Step 1: Components Here

By using arduino and IR Receiver TSOP 1738 (in our project, you can use any ir receiver available) we can decode any infrared remote code into hex or some other format. Before constructing the circuit check datasheet of IR receiver having in your hand, hence you can connect proper bias pins and output pin. Step

Introduction Power supplies are everywhere these days. With the advent of switching power supplies, the cost of high-current supplies has radically dropped. Maybe you’ve noticed how the large, heavy, wall-wart style adapters are no longer lurking around your baseboards, falling out of their sockets? Or occupying several of your valuable power-strip positions? But not all

The typical parallel LCD used with an Arduino (16×2 or 20×4) has 16 pins. Only 6 I/O pins are required on the Arduino, but what if you could get that down to two I/O pins, and still have those pins available for other devices? The I2C interface is on pins A4 and A5 of the

Welcome to my new Weather Widget Project. A weather widget is a application that can be downloaded on your PC, laptop or a mobile device and perform the job of providing easy access to weather information.But I was always trying to make something different.So I go through the internet to get some ideas.After few days

The ESP8266 chip, and the boards based around it, have been the new hot new thing this past year. Overnight it became — almost by stealth — one of the leading platforms for the Internet of Things. This runaway success quickly gathered a community, and it’s possible Espressif Systems may repeat that next year with their new ESP32 chip. About a

Background. This project started out as an accessory for another planned KickStarter project – a smart TFT display for Arduino called CleO. Now, the display itself required 150mA current, fine, but when you add a camera with its LED lights, this goes up to 250mA and if you have 1W audio playing simultaneously, unlikely,but possible,
