The LED Blinky dual LED flasher is one of our simplest projects ever, can be assembled in about 15 minutes and will definitely get attention when worn - a very simple LED flasher, alternating between two LEDs.
With only a limited number of components, consisting of two transistors, two capacitors, four resistors, two LEDs, the PC board and a battery – this system can be assembled by a novice in a matter of minutes with common parts from around your workbench.
Average assembly of the system in less than 15 minutes is possible. The PC board is a high quality, double-sided design, complete with solder masks on both sides, plated holes along with a high-contrast silk-screen labeling 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 spot-light effect.
You can download the complete instruction manual with construction guide, schematics and detailed assembly instructions.
