Journey safer with these DIY bicycle lights

Many individuals around the globe stay in cities designed for automobiles, with bicycle use being a distant afterthought. That makes biking harmful and lights can do rather a lot to make using safer. That’s why Giovanni Aggiustatutto designed this DIY system that features headlights, a taillight, flip alerts, and even an built-in odometer/speedometer.
Aggiustatutto needed this technique to work with most bicycles, so he designed the entrance lights and controls to clamp onto the handlebars. The rear mild pod attaches to a cargo rack and must be appropriate with a variety of fashions. There are two shiny white LED headlight arrays on the entrance with built-in yellow flip sign LEDs. Additionally on the entrance is an OLED show that exhibits the velocity, time, and odometer, in addition to three buttons. The again lights encompass pink taillight LEDs and yellow flip sign LEDs in a single 3D-printed enclosure.

An Arduino Nano board controls every thing, directing energy to the LEDs from an 18650 lithium battery by way of IRFZ44N MOSFETs. A DS3231 RTC module helps the Arduino observe time precisely and that provides it the power to observe velocity — and due to this fact whole distance — with the assistance of a Corridor impact sensor. That sensor detects the passing of a magnet connected to a spoke, so the Arduino can depend every rotation. The Arduino then shows the outcomes on a 0.96” 128×64 monochrome OLED display.
Lastly, Aggiustatutto tucked the Arduino and battery into an enclosure disguised as a water bottle to forestall theft.
