High-precision air quality monitors are normally very expensive, but Tim Dye of Sonoma Technology is on a mission to change that.  He’s been working with Michael Heimbinder and habitatmap.org to create a low-cost sensor system that when designed properly and integrated into a software platforms can provide valid data. AirCasting is a platform for recording, mapping, […]

This instructable will show you how to make an RC launch system for your Estes rocket, which can be operated with a TV remote. What it does is it allows you to press the center button on your TV remote, and it’ll automatically launch your rocket. In this way it is basically a wireless version […]

A quick introduction to the Arduino Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling […]

Monitoring is the key to unlocking the energy production of the solar cell. It is easy to lose efficiency through the use of circuit architectures that assume constant energy production when the solar environment is constantly changing. The change in current-voltage properties as a solar module heats up or receives more light can be an […]

Today’s post is something I’ve prepared for a long time. Hardware-wise it’s a simple thing – ATtiny45 emulating a PS/2 device, sending a keypress when three knocks are detected in the attached piezoelectric sensor (or piezo buzzer as they are also called). But if your computer can boot on PS/2 keyboard input and you have […]

Throwies are great.  They have a minimal parts count – 2 or 3 depending on whether you use a magnet – and produce a great effect.  They are very cheap and easy but not highly efficient: 1)  They are on all the time, so on average they waste half of their energy shining during the […]

I have been researching a project which will help me with my understanding of electronics, networking, and programming.  I decided to build an online thermometer which could be used in applications that need temperature monitoring.  I currently work in a lab environment where I test, troubleshoot, and calibrate equipment which is installed in nuclear power plants […]

PUB! is a Programmable USB Button on which you can program a sequence of keystrokes. When you press the button those keystrokes are “replayed” over a USB connection. The button (which is really a rotary encoder with a built-in push button switch) is programmed using an innovative and slightly quirky interface that does not require […]

This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to pachube.com, a free datalogging site. The example requires that you set up a pachube.com account, as well as a pachube feed (for more information on setting up an input feed, please click here). Your Ethernet shield will […]

Sometimes when you’re testing a sensor or debugging a value in an Arduino project, you want to see something other than numbers flying by in the Serial Monitor. However, you want to get the sensor working quickly, and you don’t want to take the time to write code to graph it or display it in […]
