For this year's costume, I really wanted to make LED eyelashes since I just discovered tiny surface-mounted LEDs (SMD LEDs) - normally they are used on circuit boards
After doing some research, I found Soomi Park's version. While Soomi's design is pretty amazing, I wanted mine to be worn on the top lashes and have an almost continuous line of LEDs. To do this, I used 0603 SMD LEDs (1.60 x 0.80 x 0.4 mm) instead of the regular sized 3 mm. Not only can they be spaced closer together, they are also very lightweight.
Here's a materials list:
Stranded wire (typical wire used in electronics)
28 or more 0603 SMD LEDs of any color
Water-soluble glue (Elmer's glue/PVA glue)
MDF or wood for the template
Surface mounted switch (optional)
Soldering stand with alligator clips (optional)
Laser cutter (optional)
Thanks to my very knowledgeable and able co-worker Davey Taylor who was willing to teach me everything I needed to know about working with LEDs.
