If you've always thought that a T-Bone steak and a Porterhouse steak were the same thing, you'd be mistaken. They're both from the same cut and they both have the characteristic t-shaped bone in the center, but this video from the folks at America's Test Kitchen explains why one costs so much more than the other.Essentially, the real differentiator between the two is the size of the tenderloin section—or the smaller piece of meat on the short side of the bone (as opposed to the strip, which is the longer section on the other side). Because a T-Bone is allowed to have a smaller tenderloin section than a Porterhouse, that would mean that all Porterhouse steaks are T-Bones, but not all T-Bones are porterhouses. Either way, if you're ever at the butcher counter and see that the Porterhouse is much more pricey than the T-Bone (Also, if the butcher can't explain why, it's time to find a new butcher), now you'll know why, and you can opt to splurge or save accordingly.What’s the Difference Between a Porterhouse and a T-Bone Steak? | America's Test Kitchen

TSA Zombie Scanner Security Wand
This scanner is essentially an Arduino based theremin using an ultrasonic sensor as input. The Arduino blinks some LEDs in response.
It is all housed in a custom cardboard/papier mache housing with attached grip.
You will need:
An Arduino, I used an Arduino UNO.
Ultrasonic range sensor - I used an HC-SR04, generic from ebay
Piezo speaker or buzzer for sound.
Bunch of LEDs in red and white.
Bunch of resistors to prevent your LEDs from burning out. Use any online LED calculator to figure out the value of the resistor needed based on the specs of your circuit.
A couple of tactile switches and a slide switch for the battery pack.
A battery pack to make it portable.
Wire for the electronics
Cardboard and glue
Paint
Something to cover the front, plexiglas, acrylic, or I used some scrap window screen metal mesh.
CAUTION: Crafting is hazardous, pointy things and sharp things are pointy and sharp. Know how to solder and use electronics safely.
Tree of Life wire pendant
I was inspired for this pendant by this instructable:
http://www.instructables.com/id/How-to-make-a-Tree-Pendant/
I searched google images for tree of life pendant and then I decided to make my own version. After a bit of trying, this is what I came up with. I hope you like it!
