Tech blogging legend Scott Hanselman recounts how he used his keyboard’s ambient lighting to show his blood glucose levels. This may not count as cybernetics but the marriage of health tech and consumer electronics is fascinating.
However, since the keyboard has a localhost REST API and so does my blood sugar [monitor], I busted out this silly little shell script. Add a cron job and my keyboard can turn from orange (low), to green, yellow, red (high) as my sugar changes. That provides a nice ambient notifier of how my sugars are doing. Someone on Twitter said "who looks at their keyboard?" I mean, OK, that's just silly. If my entire keyboard turns red I will notice it.
