One of our best friends, Kelvin has recently shared with us his personal project on making a bicycle turning system with LED light strip and laser emit, and of couse, Arduino + Tri-Axis Accelerameter combo. I'd rather say at first sight this gadget looked no different than hundreds of DIY add-ons except its frame was 3D printed; But I was completely wrong the moment I saw it glow in the dark. Let's check it out!
This idea popped up when K was riding bicycle one night. He found it's necessary and cool to have a turning signal when riding at night. Fortunately, he knew where he can use the 3D printer, and it's easy to buy Arduino boards on line, so he made a fabulous one!
According to K's design, when the body or bicycle leans left or right above the setting threshold, the light will change like waterflow, and the color will turn as customized.
Here is how it works.
