A friend at work proposed a friendly competition between a few co-workers: to make something cool out of a Trader Joe’s green tea mint tin. Anything – whatever our creative hearts desired. The prize? Nobody cared – we’d figure that part out later. I thought it would be fun to do something electronic with it […]
Data analysis coming soon! My school is kind of strange. We don’t have a cafeteria, but we do have a four week course on “The Simpsons.” We don’t have a jungle-gym on the elementary playground, but we do have a half-buried firetruck. We don’t have a football team, but we do have a bee-keeping club. […]
Took me a little while to get started but I’ve managed to wire 2 PIR infrared sensors with an Arduino to sense motion either on the left or on the right side. The result will trigger an LED to represent each PIR sensor then I also added in a servo to be controlled – so […]
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 […]
There are a lot of things this world needs at the moment. One of them is a better mouse trap. Mice are getting smarter every day and if we’re not careful we’ll end up with Planet of the Mice. Luckily, with the help of a Makerbot Replicator 2 (its enormous 410 cubic inch build volume […]
So having worked out that I can make a remote for my Nikon D80 to do some timelapse photography. I started thinking of things I can do to trigger the remote, below video shows it working but you’ll need sound to hear the shutter going. First of all check out my tutorial for making the […]
This example simplifies the task of collecting data from the Esplora’s accelerometer and graphing it with your computer. The Esplora sends keypresses to a connected computer about the state of the accelerometer. If you open a spreadsheet application, you can log the data from the accelerometer. To start and stop the datalogging, press the down […]
This example demonstrates how to turn your Esplora into a customized computer game pad. It uses the analog joystick and the four switches as inputs to a video game. The Esplora will appear to the computer as a standard keyboard, the computer will see joystick movement and button presses as keystrokes. The configuration choosen in […]
Arduino text‘in. Key Features: 24 relays controlled by 4 I/O lines! Cell phone text using your Arduino. This project hacks a cell phone to text using normally open relays. After investigating cellular modules on the internet I decided it looks not only rather pricy, but also like a possibility that even after I had it […]
I’m cheap and skint, yet I want to do timelapse photography with my Nikon D80 DSLR. Unfortnately that requires spending some cash on an intervalometer for time lapse photography which will set me back a sizeable chunk of cash. Or I could get a remote or get the trigger system then create a delay mechanism […]
