Wow, how quickly the wearable electronics world has slid into the gutter. They’re now resigned to watching our nations finest natural resource, the butt crack. This project by [semiotech] uses a LilyPad Arduino to monitor the exposure of the wearer’s coin slot. It detects the presence of light with a photoresistor and alerts the user with the vibrations of a pager motor. This breakthrough in coin slot technology will prevent dryness and certainly reduce our exposure to domestic terrorism. We see plenty of room for future development; the Arduino is already capable of logging exactly how often your coin slot is exposed. Even if you feel this is more protection than your coin slot needs, we recommend Neutrogena’s Coin Slot Cream for general upkeep.

Yesterday, Gizmodo published a roundup of wearable gadgets for people who “don’t mind looking like a tool”. It’s interesting to see what has been deemed commercially viable and put into mass production. The list covers HMDs, embedded WiFi detectors, integrated keyboards, tech jackets, speaker hats, and others. We thought you might find some inspiration from the list for your next project. In the past, we embedded a WiFi detector in a backpack strap for our Engadget how-to. The natural choice for wearable projects is the LilyPad Arduino which was featured most recently in the turn signal jacket.
