Holiday Dreidel Light Display for Roof using Arduino

This Instructable details how to build a holiday dreidel display for your roof. It uses coat hanger wire, rope light, and an Arduino controller to control a fading demo mode and a "spin" mode. In the demo mode, the symbols fade in and out, going from one to another. In "spin" mode, the symbols flash in sequence with an increasing delay between symbols until the dreidel "stops" on one and flashes. The spin f ...

Arduino Personal Soundtrack Hoodie

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 keypad sewn into the hoodie's arms each play a given sound or tune and the tenth a ...

Star Jar Geiger counter triggered LED decoration using Arduino

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. What you'll need: A Geiger counter with pulse output (I'm using the Gieger counter from MightyOhm) A fe ...

Automatically water your small indoor plant using Arduino + pump

Have you ever wanted a little plant to brighten up your desk or home, but you're afraid that you'll forget to water it? Fear no longer! Using an Arduino, a scavenged wall-wart, and a peristaltic pump, you can set up your plant to be watered as often as you like, from a jug or any other vessel. To be as accessible to as many people as possible, this tutorial can be done without soldering. That being said, th ...

Bacon Alarm Clock – Arduino

This is a project I came up with that was inspired by my love for bacon! This is an alarm clock that is designed to wake you up with the smell of bacon. With the help of an arduino the alarm clock will already have the bacon aroma filling the room to wake you up before the alarm, or it will make you just want some bacon when the alarm goes off. Step 1: Materials 1. Arduino Uno (can be found at Newark/Elemen ...

The Motivational Moody Workout T-Shirt using an Arduino

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 bunch blue LEDs in smiley face patterns to the LilyPad board and finally a ball tilt sensor. So for it to work you have to be outsid ...

Easy Electronics Organization using Arduino

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 containers. I got one from Ikea, a "Helmer." its simple metal design fits in with my rooms decor and it ...

Bird Feeder Monitor using Arduino

This is a project to monitor the number of birds that visit my bird feeder, as well as record the amount of time spent feeding. I used an Arduino Yún and a capacitive touch sensor, Adafruit CAP1188, to detect and record the birds feeding. On a routine basis, the accumulated data is sent to a Google Docs spreadsheet to record the number and time spent by the birds visiting the feeder. Data is only transmitte ...

Sleep n’ Tweet

Step 1: The Sleep n' Tweet Now I am lucky enough to work at the greatest company in the world as a University of Waterloo, co-op student. It might not even be a company you’ve heard of yet. They’re named Upverter and we are trying to change the way people design, build, share and collaborate on electronics. My job (also the coolest job in the world) is to find interesting problems that either have been or c ...

Make a digital “meow” from analog clock using arduino

Is your analog clock just not doing enough stuff? Want to do digital things with an analog clock? This tutorial will show you how to make a Kit Cat Clock play a “meow” sound clip, at precise time intervals, using the Atmega 328P-PU via the Arduino Uno development board. In my example, the meow will occur hourly. This doesn't have to be a Kit-Cat clock either, this idea may work with other clocks that use a ...

The Wondrous Weather Cube

We created an Internet-enabled companion cube for your computer, which displays different kinds of information by glowing red or green. Depending on its orientation, and which labeled face is oriented upwards, our companion cube displays either stock readings of the NASDAQ or the outside temperature in Princeton. As the temperature or stock index changes, the Arduino inside the cube fetches updated data fro ...
