Many years back when I was still quite heavily involved in the day-to-day company IT matters, we need to subscribe to a service called “Smart Finger” when we put our servers in a datacenter. Basically what this service is all about is to allow datacenter technician to help us to press the power or reset […]
The objective is to construct a programmable hobby bot that is affordable and simple to make. The parts will be purchased from places such as Wal-Mart, Radio-Shack, any Hobby Store, or online store that is accessible to the public. The price range is 50 dollars or lower for the entirety of the robot. Step 1: […]
Step 1: COMPONENTS REQUIRED Only 4 components required – 1. ESP8266 NODEMCU or WEMOS D1 mini or any esp8266 wifi development board2. RELAY (5V or 6V)3. ULN2003 or UNL2003A (Relay driver IC)4. Jumpers (obviously or else solder it!!) The main structure of the project is that ESP8266 module will receive the signal from the MQTT […]
This instructable will guide you through the process of building a set of automaton monkeys in the style of “Hear No Evil, See No Evil, Speak No Evil.” Our design ends with two monkeys reacting at the push of a button located in the Speak No Evil Monkeys eye. This design can be extended to […]
First of all,this is my first Instructable, and I’m not a native English speaker (or writer), therefore I apologize in advance for the overall low quality . However, I hope that this tutorial can be helpful for people using a heart rate (HR) monitor system (composed by a chest strap belt transmitter and a receiver […]
Why another spot welder project? Building a spot welder is one of the (arguably few) cases in which you can build something for a fraction of the price of the commercial version with comparable quality. And even if build-before-buy were not a winning strategy, it is a lot of fun! So I decided to embark […]
There are lots of Instructables on how to use SSD1306-based 128×64 OLED displays. Many of these write-ups are very informative but just about all of them look like an unfinished science project. (In fairness, most are directed at getting up and running with the display, not creating a finished product). Here’s a quick and easy way to […]
This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and […]
In this Instructable we’ll make a robot (more like a RC car) which is controlled by voice i.e. Voice Recognition. Before I start to give you any further details one must know that this is Voice Recognition and not Speech Recognition that means the controller does not understands what you are speaking. This project uses […]
We all like to know what the current room temperature is, and sometimes what the temperature is in another room, or maybe even in your vacation house on the other side of the world. Maybe you want to monitor the temperature in your pet Lizard’s house? You’ve come to the right place to learn how […]
