Note: to see everything on one page, please go to: www.tweetingcatdoor.com After receiving many emails requesting Instructions and Kits for building the “Tweeting Cat Door “, I decided to make a version that is stand-alone and doesn’t need a computer to be run and that is easy to be put together by anyone with a

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC. Concept: Trigger gun when laser is blocked by intruding object. Note: Tilting is included for expandability but not used in this project. Skill Level: Basic soldering and basic metal works Things You Need: Toy Gun(Any will do, preferably a semi-auto) Continuous Rotation

A great project for busy pet owners. This Twitter-Controlled pet feeder automatically dispenses food in response to activity on your Twitter account. The project is controlled by an Arduino and uses the Arduino Ethernet shield to receive data from Twitter. I hacked this automatic Pet Feeder from Amazon to build this project, but you could

This instructable will show you how to create a multifunction platform with a thermometer, chronograph (count up timer), count down timer, and light display. It is also intended to be a platform for other analog sensors or any other functions you can think of.

I wanted to have an easily programmable RGB light to toss into a Jack ‘O Lantern for Halloween. Who really wants a dull pumpkin in these days of pumpkin pimping madness. So I set to work building a pocket tin sized RGB lamp that could be reused after Halloween for some other RGBing need. The

This Lazy Old Geek is also an Arduino Geek. If you are an Arduino Geek, one of the common microcontrollers used by Arduinos is the Atmega328 chip. In order to use Arduino software, the Atmega must have bootloader software on it. Okay, so I bought some blank Atmega328-PU chips from Mouser.com. TIP: If you want

We have kids. I love them to bits but they keep hiding the remote control for the satellite and TV when they put the children’s channels on. After this happening on a daily basis for several years, and after my darling wife allowing me to have an Arduino for Christmas I decided that it was

We have all seen the sweet videos on the tube! You know the magical water fountains that seems to “freeze” the water droplets in mid air, or even make them go backwards! I’ve been fascinated by these “magical” thingamabobs for quite some while now, and a couple of days ago I decided to make my very

A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro-mechanical machine which is guided by computer or electronic programming, and is thus able to do tasks on its own (http://en.wikipedia.org/wiki/Robot). Well, today you will learn exactly how to build a Homemade Magic Lamp Card Box. Really, this is two instructables

Arduino Fart-O-Meter Project Innovation in electronics often emerges from playful experimentation, and this project—though humorous in concept—demonstrates practical use of wireless communication and sensor integration. The Arduino Fart-O-Meter is essentially a system designed to measure methane emissions (commonly associated with human flatulence) and transmit the data wirelessly to a receiver unit for visualization. Project Overview
