Laundry spy

“My washer and dryer are two appliances that I’ve wanted to make “smart” for a long time, or at least smart enough to balance out how dumb I am about remembering to empty them when loads are finished. On …

Neopixel Clock

“I did it the hard way not using a Arduino but a stand alone micro processor, a PIC18F2550. This involved digging down into the registers and timings of the Micro to write the code, some of which contained assembly. This …

“This device can able to perform Frequency Counting,Oscilloscope,Capacitance Measurement,Continuity Testing,Temperature and Humidity sensing,Digital Clock having TIME and DATE.This device will be useful for doing electronic projects.”

PiGI - A Raspberry Pi Geiger-Mueller Interface

“The PiGI is built as a ready-to-go drop-in module for the Raspberry Pi to transform it into a versatile geiger counter to measure/monitor radioactivity. It will generate the required high voltage the counting tubes need to operate and it …

Art Deco FM Radio Project Using Arduino

“Dear friends welcome to another Arduino project Instructable! I am very excited because today I am going to show you how I built this Art Deco style FM Radio project using Arduino. It is by far the most complex project …

Home Automation: Automatic Switch Board With Dimmer Control Via Bluetooth Using Tiva TM4C123G

“Nowadays, we have remote controls for our television sets and other electronic systems, which have made our lives really easy. Have you ever wondered about home automation which would give the facility of controlling tube lights, fans and other electrical …

Inside the 76477 Space Invaders sound effect chip: digital logic implemented with I2L

“The 76477 Complex Sound Generation chip (1978) provided sound effects for Space Invaders1 and many other video games. It was also a popular hobbyist chip, easy to experiment with and available at Radio Shack. I reverse-engineered the chip from die …

Smart Greenhouse Sensors

“Today I will show you my little project that I built for couple of days. This set is made of 4 (four) different sensors and I think that every greenhouse owner should have it, and it should make his life …

BBQ Thermometer

“I built my own BBQ thermometer. There were many designs and hardware designs. It was not easy to bring all my wishes together. I am very satisfied with my first prototype. Two meat temperature sensors (up to 300°) and one …

IOT123 - Icos Panel Circuit Tester

“In developing the ICOS10 ASSIMILATE SENSOR HUB, I needed to verify the panel circuits as they were made. Also as the pins were being soldered on the 3P headers, I wanted a 3P male pins inserted in them to stop …
