Introduction: How to Make Blinking Bicycle LED Light Using NE555

Sometimes, when you ride a bike in the dark night. It will be very dangerous if you do not have warning devices for other vehicles such as: Reflective clothing, flashing/Blinking lights...

So, today I will show you how to make your own flashing/Blinking with IC NE555. You can attach this device to your helmet or wear it on your arm while cycling at night.

Supplies

Step 1: Make Shape the LEDs

Use a solder board with dimensions of 5cmx7cm.

You are free to be creative and make any shape for these LED lights, like heart, star, circle....

This is my DIY power supply version, you can check my video above if this is first time you see it :)

Step 3: Design & 3D Print the Box

I'm using Fusion 360 to design 3D the box and then print it with Ender 3 Pro 3D printer.

Total time to design and print about 4-5 hours.

Step 4: Assembly & Testing

Connect the controller and LED board to the 3D box. It's can be run with 3.7V-12V DC, and I'm using 9v battery here. And we're also adjust the delay time through potentiometer!
