Living in a city, I use my bike as means of transit, riding from home to work, work to studio, errands, etc. When I ride at night, I am often concerned if other vehicles/people on the road can see my hand signals when I am about to turn. To make my night rides safer, I decided to build a turn signal system for my bike!
The following instructable will go over how to use a 555 timer to flash an array of LEDs, and how to mount LEDs in an acrylic panel, and cast it in resin.
Step 1: Materials
Turn signal and circuit housing
