Simple Lie Detector Circuit

The concept behind this Lie Detector Circuit is that, we assume when a person lie he kind of pumps up his anxiety level which makes him sweat and develop moisture on his skin. We then use this piece of circuit to detect if there is moisture on his skin and based on the result we glow and LED, a green one for truth and red for lie. Of course yes this cannot be claimed as a lie detector, but you can use this to play with your friends and have fun. More than that you get to learn stuff.

High/Low Voltage Protector Circuit

This 

High and Low Voltage Protection Circuit will cut off the power supply to the appliances in case of High or Low voltage. It will also show a alert message on 16×2 LCD. In this project, we have used PIC Microcontroller to read and compare the input voltage to the reference voltage and take the action accordingly.

Earthquake Detector using Arduino

Here we are using Accelerometer ADXL335 to detect the pre-earthquake vibrations. Accelerometer ADXL335 is highly sensitive to shakes and vibrations along with all the three axes. Here we are building an Arduino based Earthquake Detector using Accelerometer.

Digital Voltmeter Circuit

We build a simple digital voltmeter 

using a popular IC for voltage measurement namely ICL7107/CS7107. Using ICL7107, we can build accurate and very low cost voltmeter. ICL7107 is a 3.5 digit analog to digital converter (ADC) which consumes very low power. The IC has internal circuit for driving four seven segment display to display the measured voltage. It also has a clock circuit and a reference voltage source.

IR Remote Controlled Home Automation using PIC

In this project you will be able to toggle (ON/OFF) any AC load using an ordinary Remote from the comfort of your Chair/Bed. To make this project more interesting we have also enabled a feature to control the speed of the fan with the help of Triac. All these can be done with simple clicks on your IR remote. You can use any of your TV/DVD/MP3 remote for this project. The different IR signals from the remote are received by the microcontroller which then controls the respective relays via a relay driver circuit. These relays are used to connect and disconnect the AC Loads (Lights/Fan).

We got our very first custom #PCB back from #oshpark for Tellybot. The bottom is just the board, and the top os with all the bits soldered and mounted on. It’s designed to sit atop a #raspberrypi.
