Hands On with the KeyChainino


If you play with your keys while waiting on something: bus, subway, fish to bite, etc., the KeyChainino might be a good device to have handy. Creator Alessandro Matera was nice enough to send me one of these devices* to try out.

It’s a pretty neat device, and I really enjoy seeing the default Arkanoid-style game played on a 5×6 LED matrix. If you get tired of that, these LED devices can be programmed using an Arduino. Although it’s not as simple as programming an Arduino directly, the task shouldn’t be too hard to execute (I’ve programmed ATTiny chips before using an Arduino, as seen here).

Pins are provided with the board, so don’t discard them, or things will be slightly harder if you want to change the program around. Several programs, or sketches are available on the Keychainino site, though it would seem the real fun would be in creating or modifying your own programs. Granted, I just received this board and haven’t tried it yet, but that seems like the real fascinating thing about this little project.

How to Make a USB Key Fob

PNY attache thumbdriveA little over a year ago, I came up with this idea to attach my thumbdrive to my keychain (no, I don’t think I was the first to do this).  Specifically, a PNY brand “Micro Swivel Attache 4 GB USB 2.0 Flash Drive” was what I wanted to attach.  As you can see from this image from Amazon.com, the thumbdrive in question does actually come with a lanyard to attach to your keychain.  Unfortunately, it is a thin string with glitter all over it.  It’s attachment to the silver base could also be suspect.  Besides not being many people’s style, it looks prone to breakage, possibly loosing all of your precious data.

A better solution, in my opinion, is to make Read more »
