How to build a Twitter-controlled pet feeder
A great project for busy pet owners. This Twitter-Controlled pet feeder automatically dispenses food in response to activity on your Twitter account. The project is controlled by an Arduino and uses the Arduino Ethernet shield to receive data from Twitter. I hacked this automatic Pet Feeder from Amazon to build this project, but you could easily modify your own motorized feeder to work.
How to make an iPod heads-up display for your car
My girlfriend, a music buff, asked me to come up with a better way for her to look at the track information of the current song playing on her iPod touch while she was using it in the car. Those of you that have or have had an iPod touch know that it’s not the easiest thing to read while driving. To see the song information you have to double tap the home button and then still the text is extremely small.
My solution was to construct a device that would interface with the iPod and take the song information and then display it on a screen somewhere in the easy view of the driver. After quite a bit of work and research I finally arrived at the product you see here. My iPod information screen displays the song title, artist, album, song time, and play/pause symbol. It provides skip back, skip forward, and play/pause playback control as well as charges the iPod.
How to build a self-watering plant with Arduino
Plants liven up any space by adding a sense of airiness and life. That is - of course - when you don’t forget to water them, and they shrivel up and die. I am very bad at remembering to water plants. That is why I built this self-watering plant to do it for me. Using a soil sensor, and an Arduino-controlled water pump, I have created a system that will never forget to do it. Instead of remembering to water my plants when the soil goes dry, I only have to remember to once and a while refill the water reservoir. In this way, I have decreased my obligation to these plants and put it off to a much later date. Perhaps further iterations of this device can be connected to a rain barrel so that I won’t even have to worry about refilling my reservoir, and the entire system can be fully automated.
How to Magnetize Your Own Silly Putty with Iron Oxide Powder
Silly Putty is already a bit of mad science in itself. It bounces, sticks, and stretches, but also breaks if it hits something too hard. It can flow like a liquid and will melt into puddles given enough time. It’s both a liquid-y solid and a solid liquid, and has the amazing power to amuse children and confuse adults. So why not make it even more crazy by adding magnetism?
