They day I read at hackaday (http://hackaday.com/tag/esp8266/) that a new $5 wifi module was available, I order a few of them to test. Now, a few weeks later I want to share my experience. This is a very simple demo using the ESP8266 and Arduino to update a remote server (https://thingspeak.com/) using a digital temperature […]

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 […]

Never again will you have to dismantle a finished project just to reuse an Arduino board! This tutorial will go through the steps involved in fabricating your own Arduino-compatible circuit using just ~$8 of parts (this includes the ATMega chip!).  This is perfect for installing and embedding in permanent pieces, as you don’t need to waste a […]

Buildings account for 20-40% of total energy use in developed countries. Window shades (or blinds) can help to reduce building energy use and improve visual comfort (i.e., reducing glare and increasing daylighting). A recent study showed that occupants are fairly inactive when operating manual roller shades (O’Brien et al. 2013) which could lead to increased […]

You probably know the game of flashlight-tag. You just run around in the dark on a campsite. You hold your flashlight and try to shine it on one of the other kids, without the other kids shining their lights on you. I wanted to make this game electronic. The Arduino is my first choice, but […]

Overview Once again, my project was motivated by my curiosity to explore interesting and unfamiliar territory.  I decided to see if I could make my own capacitive sensor and then use it in a project of some sort.  After numerous fiascoes with Arduino and computers, I was able to get the capacitive sensor to work and then implemented it […]

This project was inspired by this video from YouTube and the Pendulum Challenge Kit from Makershed.com. Its a simple game consisting of five LED lights and one pushbutton switch. The LEDs flash in a sequence and the player must press the button when the middle LED light is lit. The speed at which the lights […]

Simple Automatic Car Battery Charger This is modified version of commonly available automatic car battery charger system. I obtain original layout of this charger from one of the commercially available Chinese car battery charger and modified some of the sections of original schematic to improve the performance and stability of the system. This charger is […]

I’ve made a video documentation of my midterm project for my 544 class. To keep it shorter, I didn’t detail in the video that this is only a completed phase of a larger project: an autonomous robot seal. I was originally going to incorporate a whole body that hid his components, but this current prototype […]
