A friend gave me one of Adafruit’s circuit playgrounds (developer edition) to use, and I wanted to see would it make a good robot controller. The circuit playground is packed full of features like sensors, neo-pixels and even an accelerometer. I wanted to add a L9110 motor controller and create a small bot I could […]

n this Instructable we will simulate an Toll Booth Gate by using a manual Push Button to open and close the gate. How Does It Work? When the vehicle comes in front of the gate, the push button is pressed & the gate is opened, this is done by sending a command via microcontroller to the servo to open the gate […]

WiFi has become an integral part of our life and daily billions of people use WiFi as a method to access the internet. But the range of WiFi is limited, unlike a cellular connection. A normal WiFi router usually has a range of about a 100m in clear sight and about 20m to 50m without clear […]

This is basically a Self-Driving Car powered by Arduino R-3 Development Board and a L293D Motor Shield.It uses the data given by the HC-SR04 Ultrasonic Sensor which is connected to analog pins of the arduino board. As an additional feature, I have added a Micro 90g servo which the ultrasonic sensor is fixed to. Basically […]

In this project I’m building a physical Twitter client using Arduino and a flag, basically an arduino powered retweet indicator, whenever any of my tweets is retweeted some physical action will happen to notify me of that. You’ll need: 1. Flag. 2. Arduino. 3. Laptop with a java IDE installed on it. 4. Yellow Led […]

The Particle Photon is a microcontroller suitable for wearable project’s considering it’s small form factor and that it supports OTA updates. For those of you who do not know what a Particle Photon is it is a tiny microcontroller with on board WiFi (Cypress WiFi chip) and the STM32 ARM Cortex M3 microcontroller, which is ideal for cool […]

Recently my wife has suggested that I should lose a few pounds in weight (too much time geeking out and not enough time in the gym). With that in mind -and in true nerd fashion- I wanted to create a method to see my progress, as well as having a constant reminder to stick to […]

At milliohm levels the fixture is part of the measurement: contact repeatability, differential ADC settings, settling and the limits of the displayed digits.

Usually inventions are invented to serve a need or to solve a problem. So this small gadget that i constructed came to serve a need of mine.I have a NAS, Atom based file server, that runs on Ubuntu, but from time to time the operating system freezes and i have to cold restart it. The […]

This instructable teaches how to make our Bear With Me system, a prototype that allows two users to tangibly send and receive hugs (as well as motion) in near real-time. The bears will be able to send tweets when physically hugged.  Their hearts will glow when they receive the other bear’s hug.  The bears can […]
