Zachatronic Turn Signal

As a personal project, I challenged myself to design and produce a device that shows drivers in front and behind me that I am turning without having to remove my hand from the handlebar of the scooter for safety. As a result I came up with this design, 3d printed all of the custom parts, programmed a microcontroller, and soldered all of the components together to control this battery operated device.

Features

Blinking Lights

As the arm comes up to show the turn, red LED's both in front and in the back blink constantly until the button is pressed again to lower the turn signal arm.

Battery Operated

The microcontroller and motors are operated by four double a batteries located inside the housing for easy access and battery replacement. The switch on the side of the housing also disconnects the battery pack from the circuit to preserve battery life.

Velcro for Easy Removal

The buttons as well as the main housing are both attached with Velcro for easy removal. The housing is further secured with a Velcro strap that goes around the scooter to hold it securely in place while riding.

Custom Designed Circuit

All of the components including the microcontroller, servo motors, LED's, buttons, and the battery are connected to the circuit board located in the housing under the battery pack. All component selection, circuit design, and soldering was done by myself.
