Introduction and Motivation In the tennis and sports equipment market, there are very few advanced electronic devices assisting in the feeding and picking of tennis balls or any other kind of balls. Tennis players do not prefer picking up over five hundred balls after a long days worth of drilling, or a baseball player would …

Introduction This project was designed to aid a research study by Cornell Professors Bob Nafis and Yingxin Gao on the reasons behind the higher rate of ACL injuries suffered by female athletes. This injury rate can be up to three to eight times higher than the rate of similar injuries suffered by male athletes. The …

Documentation HelioWatcher: Automatic Solar Panel Control Jason Wright (jpw97) and Jeremy Blum (jeb373) Introduction We designed and built a system to automatically orient a solar panel for maximum efficiency, record data, and safely charge batteries. Using a GPS module and magnetometer, the HelioWatcher allows the user to place the system anywhere in the world without …
Xively (formerly Cosm and before that Pachube) is a platform devoted to simplifying the interconnection of devices and data with applications on the Internet of Things. It is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that …

This project is an update to the previous dehumidifier based you can here: http://davidegironi.blogspot.it/2013/04/avr-atmega-dehumidifier-controller.html This update adds some usefull functions. The main issue that i’ve fixed is the microcontroller crash, that happens sometimes. I’ve noticed that sometimes the controller stop running, crash or doesn’t works as expected. After some experimets, i’ve noticed that probem was due …

Rather than using an out-of-the-box capacitive touch solution for my projects, I thought I’d attempt making my own little breakout board. The idea is to use a sensor capable of triggering normal digital input pins using touch. This post covers the selected touch sensor IC, the circuit used, getting a custom PCB made and how …

This week I decided to make ATMEGA 328 board. Measure something: add a sensor to a microcontroller board that you have designed and read it. ATMEGA 328 Some of the Features of ATMEGA 328 are 1.8-5.5V operating range Up to 20MHz 32kB Flash program memory 1kB EEPROM 2kB Internal SRAM Two 8-bit Timer/Counters One 16-bit …
I’ve always thought it would be nice to have a car with a parking sensor. I don’t want to spend that kind of money until I pay off my student loans. However I do have the materials to make one myself thanks to a class I took on microcontrollers. Part of my motivation is that …
Abstract -A Roomba for boards For our ECE 4760 final project we created a board climbing robot capable of cleaning the board autonomously. The robot uses neodymium magnets to stick to the board and moves across it with two continuous servo motors. It has bumper sensors on all four sides and keeps track of its …
One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor (Build Your Own Transistor Based Mobile Line Follower Robot – First Part) and enhance it to the programmable version that use microcontroller …
