7 BRAIN GAMES TO MAKE YOU SMARTER

             Regularly challenging yourself with brain games, mental exercises and new activities keeps your mind running on all four cylinders.

In fact, adults who frequently engage in mentally stimulating activities are 63% less likely to develop dementia

than those who rarely do such activities, a New England Journal of Medicine study discovered. A University of

Michigan study found that adults who play a mentally challenging brain game every day for several weeks can

dramatically improve their memory.

The week’s worth of games and activities that follow are designed to do just that. They were developed as part

of a brain-boosting lifestyle program called the Brainpower Game Plan by by Cynthia Green, PhD, an assistant

clinical professor in the department of psychiatry at Mount Sinai School of Medicine and founder of its

renowned Memory Enhancement Program.

Playing these brain games and exercising can boost your brain power by up to 78%!

1. Name your colors

Challenge your ability to stay focused: Quickly read out loud the color that each word is printed in—not the

word itself. Try it repeatedly to see if you can improve.

                                                                                      

2. In just 7 words

Test your creativity with this verbal challenge. Write a short story—and use only seven words to tell your tale.

(Bonus: This will boost your Twitter and Facebook storytelling skills).

3. Opposite day

Build new connections between brain cells by putting your nondominant hand into action. If you’re a rightie,

use your left hand to perform daily tasks such as brushing your teeth, combing your hair, and eating. Even try

4. Find it

This teaser will help hone your visual searching skills. The table features many different symbols. Using 30

seconds for each symbol, count how many times each of the three at the top appear in the table. (Answers

below.)

5. Get the picture

Give your visual attention span a workout. Study this photograph for 1 minute. Then minimize your web

browser and write down as many of the items in the photo as you can remember. Try a second time, but before

you start, take a deep breath and actively focus on the photo. Did you do any better the second time? (Answers

below.)

6. Project notes

Get in the habit of taking notes whenever you receive critical information, such as from a doctor or lawyer, or in

any circumstance that may cause stress and anxiety—which can cloud your memory. Note taking is always a

good idea on the job, too. Try this: staple several sheets of blank paper to the inside of a project folder and use

them to take notes during meetings to produce a clear record of what you discussed.

7. Count backward

Here’s a brain game that will help keep your mind on track. Try these three exercises in simple subtraction:

Beginning at 200, count backward, subtracting 5 each time (200, 195, 190...).

Beginning at 150, count backward, subtracting 7 each time (150, 143, 136...).

Beginning at 100, count backward, subtracting 3 each time (100, 97, 94...).

Answer key

Find It game:  Number of times the symbols appeared, starting from left: 14, 18, 14

Get the picture:  Large window, blinds on large window, white sofa, white ottoman, 2 striped pillows, gold

pillow, burgundy pillow, floor plant, coffee table, lamp on coffee table, wooden object on coffee table, small

violin, 3 small windows, bookshelf, books, globe, small plant on bookshelf, small lamp on bookshelf, vase on

bookshelf, bowl on bookshelf, beige carpet.

OTG CABLE MADE BY YOU

            HOME MADE USB OTG CABLE

     USB on-the-go cables are handy as heck with Android devices. They're a specially wired cable that allows the same USB port you use to charge or communicate with a computer to be used to connect USB peripherals right to your tablet or phone. That means things like game controllers, mice or keyboards, USB thumb drives, or even USB hard drives if you have access to an older model one with a separate power supply.

There are no set and fast rules about what USB gadgets you can and can't use, or if you'll need  root to do anything with them but in general "standard" Android devices won't allow you to mount a USB thumb drive without being rooted and having a way to send the commands to mount the device, and Samsung devices running Android 4.0 or higher will. Most devices running Ice Cream Sandwich or higher will recognize game controllers, mice, or keyboards. For more information about your particular device, head into the forums and ask the hackers -- they know everything in there.

Before we get started, know up front that this is not the best way to get a USB OTG cable. The easy way is to get from a hardware storeb for a buck or so, and wait for it to be delivered. But I know I'm not the only smartphone geek who has cables laying around and would rather do-it-myself. It's fun, it saves a buck, gets some of that junk you just can't bring yourself to throw away used up, and offers instant gratification. If you're semi-handy with a soldering iron, have the parts, it's fun and it's for you. Read on past the break.

The parts and tools

You'll need a few things to get started here, but nothing too exotic -- everything you'll need is standard stuff in a D-I-Yer's toolbox.

A soldering iron. Lower wattage is better

Some fine lead-free solder

A sharp knife

Some electrical tape and or heat shrink tubing

A standard micro USB data cable

A type A USB extension cable

You'll need to attach the "micro" end of the micro USB cable to the female end of the USB extension cable. But you'll also need to solder in a jumper at the micro USB connector. Grab your micro USB cable and cut the outer jacket away from the small end. You'll need to get to the solder points on the connector itself, so you might have to dig out some hardened silicon as well.

Solder points

Pin one Red wire (VCC)

Pin two White wire (DATA -)

Pin three Green wire (DATA +)

Pin four None (ID connection)

Pin five Black wire (GROUND)

Doctor your micro usb cable

Once you have the connector open, you'll see the colored wires soldered to little pins. Those pins and wires correspond to the

chart above. What you'll need to do is jumper pin four (that's the ID connection) to pin five (ground). In a standard USB cable pin

four is open, and in a USB OTG cable pin four is grounded. You can jumper this out however you like, just make sure you have

one continuous connection between pin four, pin five, and the black wire in the cable.

Now cut the full-sized end off the USB data cable, and slide the right sized piece of shrink tubing on if you're going with shrink

tubing. Also slide a piece to cover the splice you're about to make that joins the two cables. Don't heat the shrink tubing just

yet, test things first!

Splicing the cables

Cut the male end from the USB extension cable, and strip back and inch or two of the jacket. Look at the wires and see if you

have the same colors as the first cable you chopped up. If you do, they should match color to color just fine. If you don't, see

the chart above and open the male end you cut off and check the pins. You could also ring out the wires with a multimeter if

you have one handy. Just make sure you know which wire is which if they don't color-match.

Carefully solder the two pieces together, making sure to put your shrink tube in place before you make the connections. This is

going to wiggle and move a lot, so take time to have good, solid solder joints.

Testing it

Once everything has cooled down, carefully plug the cable into your phone or tablet. Grab an old wired USB mouse, and throw

it on the other end. In a few seconds you should see a mouse pointer on your device! If the mouse you're using has a sensor

instead of a ball, you'll also see it light up as soon as you plug it all in.

Yes, having a mouse connected to your phone or tablet is cool in theory, but not very practical. This was just to test the

connections. If everything is working, heat your shrink tubing or tape up the points of the cable you opened. A mouse uses the

same four connections as any other USB device, so if it works you're good to go.

Making it useful

If you have a  Galaxy S 3 , you can plug a thumb drive right into the cable and go. You'll find a new folder called USB storage in your file explorer, which will be all the stuff on your thumb drive. If you're using a Nexus 7 or a Galaxy Nexus or anyother device, things are a little more involved.

Stock  Jelly Bean can see and recognize a USB thumb drive, but the system won't just auto-mount it. That means it's there, but you can't get to it. The Android developers have said this is done on purpose, as they provide everything to make it happen except a UI. Without a UI, they don't want it to happen automagically. The last time the subject came up on Google+  it turned

into quite the debate. Read it and see both sides.

For now, the only option I can find needs root. Yes, the code is there for it to be done without root, but it seems that no developers have done it yet. If you're rooted, just install StickMount from Google Play . Now when you plug a thumb drive in you'll get a prompt for StickMount to start, and it mounts the folder so you can get to the files.

The good news is that even without root things like gamepads and DLSR camera cables now work. But that's another post for another weekend.
