Introduction: Shining Bicycle Turn Signals
First, I publish this stuff for my friend K. He is a very young shy man and not good at English. I believe he is kind of creative maker. Although my English is just a little bit better than him, I will try to introduce his wonderful work to all of you.
Second, 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 turns left or right above the setting threshold, the light will change like waterflow, and the color will turn red.
Let's see how K made this shining turn signal step by step.
Step 1: Materials
Step 2: Print the Main Body
Use 3D printer to make the main part of this turn signal.
This one is look like two arrows at each side.
You can design it yourself, if you like wings, butterfly or anything else.
Step 3: Install the LED Strip
Weld the wires to the digital LED strip and then insert the strip into the main part.
Those LED lights need to be put evenly.
Step 4: The Circuit
At first we can try on the breadboard.
The two resistors are needed.
Step 5: Programming the Arduino
The software is attached.
Two additional DLL are needed.
Step 6: Put Together
Insert the bluno and ADXL345 to the protoboard.
Fix the board into the plastic main body.
Connect to the electricity, and see if it works.
The color is changing.
Step 7: Attach the Lasers
The laser supports are also made by 3D Printer.
Insert the laser to the support and then glue the support to the main body.
