here is growing interest in the commercial production of high-value specialty fruit such as strawberries, blackberries, raspberries, and blueberries. Much of the small fruit grown in North Carolina is currently marketed through pick-your-own establishments or roadside stands. A strong demand for these small fruit items from grocery stores and restaurants has prompted many growers to consider expanding their ...

For a class on technology in libraries, I had to create a project that used the LilyPad Arduino, and I chose to create a stuffed animal that sings “Jesus Loves Me” while lights flash with the notes. I made a fox, but the pattern to which I’ll link can be used to make a raccoon as well.

Upon the needs of the (2014) World Barista Championship Rules and Regulations, an adequate and precise time measuring is needed during the competition. These measurements are usually done by regular stopwatches with all the benefits (ease of use, common availability) and drawbacks (two stopwatches needed for each judge, as well as some mathematics are necessary for supervision). This Arduino-based stopwatch ...

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 time to make something useful (in her eyes!) with the Arduino. So here we have the culmination of that: a web-based in ...

I am taking a Children and Technology course for my MLS this semester, and one of our assignments is to create a toy using the LilyPad Arduino development board. The LilyPad Arduino is used to create e-textiles that you can program to do various things. In this instructable, I will walk you through the process of creating a rocket ship cape that lights up and plays a scale. Step 1: Step One: Materials Sewin ...

What it is: Sometimes we want to send special messages to the ones we love but they are sleeping. Soci Alarm Clock allows you to record a message from your browser and send to your beloved’s alarm clock. They just have to put it near bed, with the soft mat under the pillow. How it works: Soci Alarm Clocks runs in a node server. There is a browser interface in which users can login and see if their partner i ...

At home the cookies disappear relatively fast. ¿Why? Well, principally because of me and my father. That's why my mother and my sister have to hide some to eat them later. It's embarrassing, I know, but it's because we are like "Oh, I want to eat a cookie", and some time later "I will eat another", and so on, and when we realize, we have eaten more than a half of the cookies. That's why I decide to make thi ...

I created the Nursery Rhyme Hat for a class on youth and technology.  I'm new to instructables and e-textiles, so please bear with me! This is the first time I have used the Lilypad Arduino or any kind of soft circuit technology, so my coding is borrowed from several others (more on my code in Step 2). All in all, it was quite the learning experience creating this hat and I'm excited to share it with you! S ...

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 soldering iron and a little time on hand. All the software is available to download, but feel fr ...

Since you've gotten into electronics, haven't you wondered if there is a fart sensor out there?  I sure did.  I discovered that if you use a methane sensor, especially the MQ-4, even at very low concentrations, it reads farts.  What if you combined that into a hat with an LED Bar Graph and a XBee?  Exactly.  The Gas Cap was made with that in mind.  For around $100, you can build your own Gas Cap, a human ga ...
