FriendlyFox is the take anywhere, no-hassle furry friend for the modern
girl. With soft pet-able fur and a pleasing, vibrating 'purr' sensation
when you stroke its head, FriendlyFox is the perfect pet for those
without the time or effort required for a 'living' pet that still want
the pleasure of furry companionship.
I found this really awesome blinking, dancing, singing skanky doll toy in Bushwick this weekend that was absolutely too incredible not to hack. Unfortunately I won't be with you tomorrow to hack in person, but I documented her in all her plastic-y glory for your viewing pleasure:
Meet Skanky Dancing Doll
Check out her moves!
without skank-wear, note LED belly button ring, this doll is so classy
What is a capacitor? In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them. Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won't be a particularly good capacitor in terms of its storage capacity, but it will work. In theory, the dielectric can be any non-conductive substance. However, for practical applications, specific materials are used that best suit the capacitor's function. Mica, ceramic, cellulose, porcelain, Mylar, Teflon and even air are some of the non-conductive materials used. The dielectric dictates what kind of capacitor it is and for what it is best suited. Depending on the size and type of dielectric, some capacitors are better for high frequency uses, while some are better for high voltage applications. Capacitors can be manufactured to serve any purpose, from the smallest plastic capacitor in your calculator, to an ultra capacitor that can power a commuter bus. NASA uses glass capacitors to help wake up the space shuttle's circuitry and help deploy space probes
Arduino analog synthesizer using Audino code from tinker.it. The potentiometer "mouth" controls tone while the IR sensor in the "eye" controls volume for switching notes. Unfortunately I fried the IR sensor during the final wiring so the current prototype has a non-integrated potentiometer for volume control.
