iPad Home Button Child Lock

iPad Home Button Child Lock

Next to duct tape, the binder clip has to be one of the more universal go-to items when improvising a short term solution to an interesting problem. If you’ve ever enjoyed the magic of child iPasification then you are also aware of the annoying little issue of said child clicking the home button and potentially wreaking havoc on your device. A software solution is not out of the question, but if you’re looking for a quick fix you might want to consider Carlos J.

It may not be foolproof since kids are pretty inventive when it comes to breaking into things, but at least you can take advantage of their poor motor skills as a deterrent.

Morse For The Hard-Core: Replace Your Keyboard with a Key

Here’s a fairly radical way to motivate yourself to learn Morse, from Australian Ben Buxton. Got to agree with tipster Alan Dove, who described the build as, “a project involving Arduino programming, a mint tin, a USB interface, and International Morse Code, resulting in unassailable geek cred.” The USB key interface is built into a mint tin and provides a dual input port for a standard USB keyboard to access non-Morse characters. A numeric display on the tin displays your coding speed, and tapping out “SOS” without letter spaces brings up the settings menu. Software, schematics, and build notes at Ben’s site. [Thanks, Alan!]
