    After carefully disassembling the "finger light", I created a mechanical replacement for the LED. The cheap "finger light" used the cathode of the LED as part of the mechanical switch to turn on power to the LED. So a mechanical replacement was required. After soldering it together, I checked to make sure it was working and reassembled the "finger light"....

    No not that kind of nail! A fake acrylic finger nail! after taking my bits and pieces home, I experimented with gluing a red LED to back of some of the nails. It work amazingly well and after applying power, the nail was very brightly lit. Now some engineering questions started happening. If someone glues one of these to their finger, they can't exactly take a shower with the battery attached, so i needed to come up with a connector that was small, robust and above all... pretty! what i came up with is the small the connector commonly used on wifi and bluetooth modules called a U.FL connector. It had golden contacts (pretty!), it was small and easy to use....

    On a non-specific Saturday a few months back, I was with my wife grocery shopping at our local Walmart and terrible bored.... and like any good nerd i attempted to entertain myself with fun engineering challenges. One on of the isles there were some interested "rings" hanging on an advertisement pole:

    For the wonderful price of $2.99USD, I got three "finger lights". So, here we were walking around Walmart doing our shopping with me thinking about what to do with these "finger lights". As it happened, we passed the cosmetics isle and I spied the fake fingernail kits and they reminded of diffused LEDs and bingo... LED illuminated fake nails!

    to be continued!
