About So for my Junior prom, I really wanted a dress I had seen online that was blue with a sequin ombre, but it was out of my price range, and way too voluminous. My mom and I had made my Homecoming dress the year before, so we decided we could tackle a prom dress, and after some internet surfing lead me to discover the Arduino had a sewable model, I was sold on the idea of making my prom dress. We stocked ...

Story This is a small semaphore you can put on your desk. You can use it to tell whatever you want to the people around it. For example, because you need some concentration and you'd like your colleagues not to disturb you. Or to tell the status of the system you're managing. Or say which mood are you today. The possibilities are endless! I wanted the thing to be dead-simple to use. It's not connected to In ...

Introduction I've been fascinated with joule thief circuits since I made my first one.  It's amazing what all you can power from a single AA or AAA battery.  The only problem is you can't do much beyond light up an LED because the current isn't "always on".  With a couple of extra components, you can take your joule thief to the next level!  While this circuit isn't particularly useful o ...

Brainstorming Process After selecting Kroeber Fountain as our location of interest, we began to notice that it was a place at which people would congregate without interacting with one another. The fountain’s shape - most notably, its tiered steps - affords it the ability to serve as a seat where multiple people can sit in close proximity to one another and still manage to treat each other like strangers. W ...

Overview This project builds a Christmas lights controller for the GE Color Effects lights allowing programmed control of up to 8 sets of Christmas lights. Furthermore, it provides a function specific language for programming patterns for these lights and an emulation environment for testing the programs requiring the lights to be built or hung. Pre-reading Arduino - If you have never heard of an Arduino, t ...

This alarm is a good way to alert you if somebody messes with your bike. I had a bicycle stolen a while back and decided there had to be a better way to keep my bike secure. When I searched for bicycle alarms, all I could find were alarms that responded to sudden movement or when a lock was cut. Also, the reviews of these products rated them mediocre at best and said they often did not work or gave a lot of ...

This is my instructable on charlieplexing a LED row/string with the arduino. I noticed that there weren't many instructables on charlieplexing using an arduino, so i made this. I tried to keep the project simple, but that didn't work very well. The soldering is complex, I wouldn't recommend this as a first time soldering project. Here's some background on charlieplexing: en.wikipedia.org/wiki/Charlieplexing ...
