Pretty neat images.  As with most of my latest photos, I’m using Read more »

codekase light onToday I was asked if we should toss an advertisement from a car dealership.  It had some sort of key thing attached to it, so instead of just throwing it away, as was my first instinct, I decided to investigate further.

Apparently the “key-thing” was a “CodeKase”, which makes a number light up when the tag is pulled.  This works like a flashlight (it is a LED light), and the components inside are two batteries, a little LED, and a diffuser.

To take one apart, all you really have to do Read more »
