77 Brain Hacks to Learn Faster, Deeper, and Better Source: Online Education Database If someone granted you one wish, what do you imagine you would want out of life that you haven't gotten yet? For many people, it would be self-improvement and knowledge. New knowledge is the backbone of society's progress. Great thinkers such as Leonardo da Vinci, Thomas Edison, Benjamin Franklin, Albert Einstein, and others' quests for knowledge have led society to many of the marvels we enjoy today. Your quest for knowledge doesn't have to be as Earth-changing as Einstein's, but it can be an important part of your life, leading to a new job, better pay, a new hobby, or simply knowledge for knowledge's sake — whatever is important to you as an end goal. Life-changing knowledge does typically require advanced learning techniques. Here are 77 tips related to knowledge and learning to help you on your quest. 1. 2. 4. 5.

The Basics of USB Battery Charging: A Survival Guide Table of contentsIntroductionAn Array of Power SourcesDetecting the Source TypeUSB Connection TerminologyPort Detecting and Self-Enumerating ChargerAdding Port DetectionOther Charge StrategiesUSB 3.0"Cheating"—Noncompliant USB ChargingWrap Up Introduction USB has become as much a standard for connecting power to portable devices as it has for serial communication. Recently the power aspects of USB have been extended to cover battery charging as well as AC adapters and other power sources. A tangible benefit of this wide-spread use is the emergence of interchangeable plugs and adapters for charging and powering portable devices. Arguably the most useful benefit of USB's power capabilities is the ability to charge batteries in portable devices. Charging batteries with USB requires balancing battery "care and feeding" with the power limitations of USB and the size and cost barriers ever present in portable consumer device designs.

5 Ways To Hack Your Brain Into Awesomeness Much of the brain is still mysterious to modern science, possibly because modern science itself is using brains to analyze it. There are probably secrets the brain simply doesn't want us to know. But by no means should that stop us from tinkering around in there, using somewhat questionable and possibly dangerous techniques to make our brains do what we want. We can't vouch for any of these, either their effectiveness or safety. #5. So you just picked up the night shift at your local McDonald's, you have class every morning at 8am and you have no idea how you're going to make it through the day without looking like a guy straight out of Dawn of the Dead, minus the blood... hopefully. "SLEEEEEEEEEP... uh... What if we told you there was a way to sleep for little more than two hours a day, and still feel more refreshed than taking a 12-hour siesta on a bed made entirely out of baby kitten fur? Holy Shit! We're pretty sure Kramer did this once on Seinfeld. How Does It Work? #4. #3. 1. 2. 3.
Logic Signal Voltage Levels : Logic Gates Logic gate circuits are designed to input and output only two types of signals: “high” (1) and “low” (0), as represented by a variable voltage: full power supply voltage for a “high” state and zero voltage for a “low” state. In a perfect world, all logic circuit signals would exist at these extreme voltage limits, and never deviate from them (i.e., less than full voltage for a “high,” or more than zero voltage for a “low”). However, in reality, logic signal voltage levels rarely attain these perfect limits due to stray voltage drops in the transistor circuitry, and so we must understand the signal level limitations of gate circuits as they try to interpret signal voltages lying somewhere between full supply voltage and zero. TTL gates operate on a nominal power supply voltage of 5 volts, +/- 0.25 volts. If a voltage signal ranging between 0.8 volts and 2 volts were to be sent into the input of a TTL gate, there would be no certain response from the gate.
Radial Air core alternator Radial Air core alternator Fun! These are simple radial air core alternators that anyone with a drill and jig saw can build. Below are the basic parts for a single magnet 3 phase alternator... 2 plastic triangles sized to match the width of the magnet your using, 1 magnet, some small wooden dowl, 2 1/4" round steel stock ( cut bolts work well ), and some 1/4" bar stock that closely matches the thickness and width of the magnet your using. Also, some copper magnet wire for the coils. Below shows the basic frame assembled... Next you'll wind 3 coils that will fit around the frame... I used 100 turns of #28 wire as an experiment and it worked pretty well but you can adjust the amount of turns you want based on the voltage you need. Lay the 3 coils over the triangles and tape the coils together. Below is a picture of the completed unit... It easily lights LED's as well has the ability to charge nicad batteries... give it a spin ! Want more? Here is a shot of the parts you'll need to make...

What’s The Difference Between HBM, CDM, And MM Test? | Power content from Electronic Design Electrostatic discharge (ESD) and electrostatic overstress (EOS) events can happen anywhere such as fabrication and assembly process areas, production testing environments, transportation, and field applications. (See “Understanding ESD And EOS Failures In Semiconductor Devices”). EOS and ESD may be caused by the user’s application due to a transient, excessive supply current, poor grounding, low resistance path between supply voltage and ground, shorted pins, and internal damage of the circuit. The IC may eventually fail if it’s exposed to conditions beyond the datasheet specifications. ESD Test Models Semiconductor devices include ESD protection circuitry. HBM simulates ESD due to discharge from human beings. Human Body Model When people walk, they generate some electricity and discharge it to ground. ΔV/Δt = n Δq/C where n is the number of steps/second and C is the person’s capacitance. For HBM tests, there is a simple series RC network to simulate the discharge from a human body. and:
