The video isn't exciting but it's cool, showing the actual spoofing
of an RFID signal -- the maker's antenna and an actual RFID tag,
both scanning the same. RFID tags are all over the place. They're
used in building access control systems, passports, inventory
tracking.... This instructable will show how you can use an Arduino
and a few simple components (wire coil, transistor, capacitor,
resistor) to make a device that can spoof an 125 KHz (low
frequency) RFID tag. This is version 1, so there are many
enhancements that can be made, but this version is stupid simple,
yet it works. I did this in a few hours without much previous
knowledge of RFID and without any fancy equipment (like a radio
tuning hardware or an oscilloscope). Read more | Permalink |

Arduino Assisted Mind-Controlled TV
Arduino Assisted Mind-Controlled TV! Paul writes - I have finally
gotten around to re-writing some of my old code and re-recording a
proper demo of controlling physical objects using thoughts by
interfacing an EEG headset with an Arduino. While this technology
is interesting and exciting, before anyone sees this as an
endorsement for this particular EEG headset, I strongly recommend
reading my full review of the device below. Those of you who have
no interest in purchasing such a device can simply enjoy the show.

Vegetable synth
It's a bit hard to dance to (I tried, please don't tell anyone) but
I dig it. From Arduino forum member Jochem van Greiken: This is a
project I made for the first year fine arts at HKU in Utrecht. It
uses 12 nails in a wooden fruitbowl to sense the resistance between
different fruits and vegetables. This then goes to an arduino mega
and gets send to max/msp with the arduino2max patch. I then used
some low frequency oscilators and a heavy subwoofer for that real
body feel. In the Maker Shed:

Electromagnetic geospacial globe
Geek Dad John Knight built this "Electromagnetic Geospacial Globe
and Remote View with Obligatory Goggles" with RFID tags and reader
(Touchatag) to remote-control Google Earth on a steampunk'd tablet
computer. Oh, and the goggles? They don't do anything special. Yet.
John will be showing how he built it and talking about it this
morning at Maker Faire Detroit. He'll be presenting at 10am, at the
MAKE Demo Stage. Steampunk Globe Read the Full Story » | More

John Park in the Maker Shed: PIR Arduino motion alarm
Want to learn how to hook up a passive infrared (PIR) sensor to
your Arduino? Check out this video I put together doing just that.
These sensors are very nice to work with either by themselves
(along with a transistor or relay) or on a microcontroller. You get
about a 20 ft. range for detecting motion from humans, animals,
other things that emit a decent amount of infrared radiation. WILL
NOT DETECT THE UNDEAD. This is the same alarm setup I used to prank
my kids on April Fools' Day. In the Maker Shed:
The PIR Sensor detects motion up to 20 feet away by using a Fresnel
lens and infrared-sensitive element to d...
