Mathematics explains why your earphones are always tangled

All bad news on the tangling front — if headphones are shaken, as in a pocket or bag while you are walking, the cords will tangle. Shorter, stiffer cords may help a little, but the only thing known to work is a pair of wireless earbuds.

Using a USB flash drive with your smartphone or tablet (video)

Flash drives — so useful. Almost everyone I know has a small collection. What would make them even more useful would be if they could be plugged into your phone as well.

And the good news is: they can! A growing number of Android devices have USB OTG (USB On The Go), which allows connection of USB devices. Only one problem remains: Android devices have micro USB connectors & flash drives have full size USB — except a few have both:

Leef Bridge



SanDisk Ultra Dual



If you want to use your existing USB flash drive with your mobile device that has USB OTG, try a USB-to-micro USB adapter.

iStick

If you have an Apple i-device with Lightning connector, there's something for you too:

AirType keyless keyboard (video)

Appears to include a pair of strips which fit across the hands, at the top of the fingers. The strips sense the movements of the user's fingers, & after a learning process, can be be used as a replacement for a conventional keyboard. Most appropriate use would be with a device which does not have a satisfactory keyboard, such as a phone or tablet.
