Oscilloscopes are an essential tool for electronics hobbyists and professionals to verify that their designs would work as expected. PC-based oscilloscopes score over standalone oscilloscopes due to their compact size, low cost and ability to do offline analysis. Here we describe how you can make your own oscilloscope at a very low cost using your …
Ever felt the need to have a tiny, yet functional, RGB backlit keyboard, no bigger than the size of a single key? No? Who cares, make one anyway! This instructable will guide you through the steps you need to make your very own, slightly useless, one button keyboard. …
Amazon’s Alexa is cool. USB fans are cool. Alexa enabled USB fan, even cooler. This fan turns on with a voice command to an Amazon Alexa device, “Alexa, turn [insert your name here]’s fan on”. The fan is also set to turn off automatically after 45minutes (adjustable through code). The weather has been hot lately …
Not too long ago I saw the “Awesome Button” video on the Make Magazine podcast. In the video Matt Richardson shows how you can take a Teensy development board and turn it into a simple USB keyboard. In his example everytime a button is pressed a synonym for the word “awesome” is sent to the computer. While this is …

The tutorials we used. http://www.instructables.com/id/Touche-for-Arduino-Advanced-touch-sensing/?ALLSTEPS http://www.instructables.com/id/Calm-Relaxed-Interaction-Plant-Plus-1/?ALLSTEPS Download arduino software and the processing software. From their respective websites. Processing.org arduino.cc All of the supplies we used: (we didn’t include the water bottle as a sensing object, and used an inductor instead of a coil) Arduino Usb cable Shield pin headers Resister: 10k, 1MOmh, 3,3k Capacitor: 100pf, …
Obstacle avoiding vehicle, continue in “3D Laser Range Finder” series ( project 1, project 2). The basic idea is the same, measuring distance using red laser pointers, CCD analog camera and Arduino UNO. Modification was made in geometry. Two lasers were set for “far field” obstacle detection, few meters in front of vehicle on left or right …
I’m researching squeeze sensing as a mode of tactile interface. Here I will cover the process of developing a squeezeable sensor and the firmware/software concerns associated with interpreting the data from the sensor. This fulfills the “sensor project” for my class called Computational Principles in Media Arts taught in AME at ASU by Todd Ingalls and Hari …
This server room environmental monitoring system is a low cost high performance device with the same onboard features as commercial devices costing hundreds of dollars more. In addition to a low cost platform we will provide low cost sensors for many important devices to insure your equipment stays safe and sound. Full instructions are available …
The Time Sensing Bracelet is a fabric potentiometer. You select your desired time of day by making contact in the corresponding position on your wrist – where your watch would normally be. There is no point to it but fun. Update: Using some wire wrapped around the central popper to make contact with the resistive …
In this project, we will demonstrate how to build temperature sensor circuit using a LM335 sensor. As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay this temperature to us back in degrees Kelvin. The difference between an LM335 and LM34 and LM35 temperature sensors is the LM335 sensor …
