LED Blinky - Dual LED Flasher Kit

The LED Blinky dual LED flasher is one of our simplest projects ever. It can be assembled in about 15 minutes and will definitely get attention when worn. This simple LED flasher alternates between two LEDs.

With only a small number of components—two transistors, two capacitors, four resistors, two LEDs, a PCB, and a battery—this project can be assembled by a novice in a matter of minutes.

Average assembly time is less than 15 minutes. The PCB is a high-quality, double-sided design, complete with solder masks on both sides, plated holes along with a high-contrast silk-screen labeling for component positions measuring only 1.2" x 1.2" (31mm x 31mm). The design allows for the placement of a variety of sizes of LEDs including tiny 3mm models, standard 5mm models, all the way up to the huge 10mm models. The best effect is achieved when using LEDs with a frosted lens which produces a nice glow as opposed to regular LEDs which produce a spotlight effect.
