*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

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

This was a fun project. Push the red button, watch the dice ” ROLL ” then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone board. Powered by 4 AA NiMD batteries. Can you find the SECRET SWITCH in the main picture? Where is

Have you ever wanted to use a good old knob to control your TV volume instead of repeated button pushing? Or make it controlled by light? Do you want your remote to be replaced by an awesome arduino and let it do the hard work of using a remote for you? Well this instructable is

Well it’s that time of year again. That’s right, the sun is going down early, and it’s getting hard to avoid logging some miles on your bike after dark. You likely have great lights front and rear already, but what about on the sides of your bike? When crossing intersections, and cruising down those long

This instructable builds on top of the Geiger counter triggered LED decorations I made last year. This version powers the Geiger counter from the Arduino (itself now powered from a mains adaptor, so I no longer need to keep feeding them batteries) and the LEDs now fade in and out for a more gentle effect.

This was inspired by Raj’s personal soundtrack shirt in Big Bang Theory S3, E16, “The Excelsior Acquisition”. You can now buy them online but it’s much more fun to make your own and it’s possible now that buttons designed for use in electronic clothing are available from Connectedwear. Nine of the buttons on the Connectedwear

I call this project “The Motivational Moody Workout T-Shirt” . Basically what I wanted to do was a t-shirt that makes you want to get out in the open and work out. To make that work, I sewed a LilyPad arduino onto a t-shirt and powered it with a solar panel. Then I connected a

Like many other electronic enthusiasts I need to have a constant supply of materials in order for us to keep building, hacking, or just playing around with electronics. However as probably any of us have come to realize we need a lot of space and storage to hold every thing. Enter the world of stack-able
