Adafruit industries took a little field trip recently to W/—— project space in Chinatown, NYC to check out Peter Sand’s robot-tended garden.
The giant robot creates a garden, plants seeds, waters them and lovingly tends to it - the operator can control the robotics with a game controller and for the Arduino fans, it has an Adafruit protoshield and Arduinos that help the gardening.
The Tin Can app takes advantage of the iPhone’s audio ports to send and receive messages using sound. This deceptively unadorned app points the way to jailbreak-free hardware solutions for the iPhone -
For those of you who are technically inclined, Tin Can uses frequency shift keying (FSK) to send data from one iPhone to the other. This is the same technique used by early modems to transmit data.
FSK uses alternating frequencies to represent binary data. For instance, to transmit a ‘1′ using FSK you might use a 4 kHz signal, whereas to transmit a ‘0′ you might use a 3 kHz signal. You would then alternate the two frequencies to send sequences of ones and zeroes.
What we have done, in essence, is turn the iPhone into a simple modem using its speaker and microphone. Pretty cool.
A $1.99 round teak tray is easy to convert to a unique button tray. Great for a gift to a friend with a new home, a shower gift or a birthday gift. Wrap it up with a bottle of wine for the perfect gift.
Measure and Mark
Measure and mark the center of the tray with four pencilled dots to look like …
Here’s a robo-blimp that some students at Colorado State University designed. They score points just for coming up with the name infraLED Zeppelin. The article includes PDF build instructions and a complete parts list.
Smoking dates back to as early as 5000 BC, yes we know its bad for you. This Instructable is for those who consciously decide to smoke, recognising the dangers involved and accepting those risks. If you don’t smoke, don’t start!
Here’s a piece on the WowWee RoboCommunity forums about adding LEDs lamps onto the head-stalk of your Rovio. One of the criticisms of the Rovio is the rather poor camera mounted in the head. The lack of lighting on the head-stalk doesn’t help. If you try and look up at something with your robo-head, and there’s inadequate lighting where you’re looking, you’re pretty much screwed. Adding these two bright-white LEDs can help (or at least I’d assume so).
This Arduino based Capacitive 3D Controller that Kyle McDonald built looks like it is way to simple to function. Have a look at the video to see the amazing type of accuracy this device is capable of. The possibilities are endless for this cheap setup, I can imagine a security pass code that is not […]
