Final Assembly and Use

Arts & crafts time!
The electronics can be held in place temporarily with masking tape while a more permanent bond is arranged…
A few strategic dabs of hot-melt glue then hold the strip, Trinket, wires and JST plug in place. The latter gets a sizable glop, since the battery will be plugged and unplugged repeatedly here. Once the glue is fully set, the masking tape can be removed.

Hot melt glue works fine to hold the wires and Trinket in place, but can be disappointingly nondurable. E6000 craft adhesive (one of our favorites) dries clear and flexible with a very strong bond, but the fumes are a bit noxious and it takes 24 hours to set completely. Choose wisely.
To prevent accidental contact with skin (which is slightly conductive, especially if damp with perspiration), the back side of everything is covered with tape.
Hot glue and tape are rather kludgey, but it’s all hidden on the inside. From the front everything looks pretty slick (and the blinking LEDs will provide further distraction from any imperfections).
The tiny LiPo battery can be held with tape at the bridge of the nose (between the eyes it won’t block vision), or could be affixed to one of the temples.
Bingo! You’re done!

Using the code as provided, the battery should run for about two hours. Different colors and patterns will have a different current draw and run time; this is nearly impossible to predict, sometimes the best way is just to plug it in with a freshly topped-off battery and see how long it runs.
To recharge the battery, unplug it from the socket on the glasses and use the LiPo charger. The battery does not charge from the USB connection.

SAFETY AND COMMON SENSE

Unlike the LED goggles, you can wear these shades on your eyes in an appropriate setting. Just remember that your sight is limited as the electronic parts may block peripheral vision. Also, LEDs look best in the dark, but navigating in an already-dark setting is made even more difficult by sunglasses. Use common sense; they’re fun and nifty looking for indoor parties, but don’t go driving at night with them.
