Encapsulated in a tiny 9.0×6.5×1.83-mm QFN package, the ISL8203M step-down DC/DC power module from Intersil furnishes an adjustable output voltage between 0.8 V to 5 V to allow designers to use one device to build a single 6-A or dual 3-A output power supply. The ISL8203M simplifies power-supply design for FPGAs, ASICs, microprocessors, DSPs, and […]

The small but charismatic Hawaiian bobtail squid is known for its predator-fooling light organ. To survive, the nocturnal cephalopod depends on a mutually beneficial relationship with the luminescent bacterium, Vibrio fischeri, which gives it the ability to mimic moonlight on the surface of the ocean, and deceive monk seals and other predators that would happily make a meal of the small creature.

Liquid crystal elastomers (LCEs), essentially rubbers with liquid crystal properties, can do a number of fascinating things, especially in the fields of optics, photonics, telecommunications and medicine. They can curl up, bend, twist, wrinkle and stretch when exposed to light, heat, gases and other stimuli

(Phys.org)—Andromeda IV, discovered in 1972 by Canadian astronomer Sidney Van den Berghan, is believed to be an irregular satellite of our neighboring Andromeda galaxy, also known as Messier 31. Now, a new study conducted by an international team of scientists led by Igor Karachentsev of the Special Astrophysical Observatory in Nizhnij Arkhyz, Russia, tells a different story regarding Andromeda IV’s true nature

Here’s the finished DAC! it was a very fun project and very fulfilling to make something that I actually use everyday. Overall the audio specs aren’t anything amazing, but it definitely is an improvement on the built in audio of my computer. Another Shot of the Finished DAC Pretty Blue Lights!!! There are two LED’s […]

The diversity of mammals on Earth exploded straight after the dinosaur extinction event, according to UCL researchers. New analysis of the fossil record shows that placental mammals, the group that today includes nearly 5000 species including humans, became more varied in anatomy during the Paleocene epoch – the 10 million years immediately following the event.

Most horses today are treasured for their ability to run, work, or be ridden, but have lost their wild-type camouflage: pale hair with zebra-like dark stripes known as the Dun pattern. Now an international team of scientists has discovered what causes the Dun pattern and why it is lost in most horses

JabberBot is controlled via an Android application over a bluetooth serial connection. The guts of it are based on an I2C adaptation of the Adafruit WaveShield and MotorShield. The bluetooth module is a Bluetooth Mate Silver from Sparkfun. What does this thing do? The android app running on the phone (powered by CyanogenMod) connects to the […]

Two newly-developed systems for driverless cars can identify a user’s location and orientation in places where GPS does not function, and identify the various components of a road scene in real time on a regular camera or smartphone, performing the same job as sensors costing tens of thousands of pounds.
