Hi buds !

Here is the second version of the 3D printed universal bike light for the rear of your bike !

HD quality for the timelapse is available !

Take everything you need : (kit available soon !)

Magnets (could work with hard drive ones)

coil from a relay ( you can find in any electronic shop)

2x LEDs 10000 mcd or more if you find to shine in the night !

2x 10-32 Screws and bolts to tight the light

2x 4-40 screw and bolts to tight the magnet on the wheel

Ring which fits on your bke ( you can find from old bike parts) soon 3D printed

Rubber bands

3D printed parts :

Support of the coil

Top of the box

Link to fix the light on the ring of

Tools :

Cisors

Soldering iron

Eventually glue

Atmosphere to assemble it :

Music : free of your choose, I suggest nice radio, classics works well, Rolling Stones, Nina Simone, Vivaldi…

Friends : try to find cyclist they’re often more interested

Well… stop joking, let’s assemble it ! Count 5-10 minutes to do it

(As for everything the more you prepare the fastest it goes !)

Take the 2 Leds and the coil.

Solder it so that each LED is in a different way, one positive, one negative.

The electricity you’re making is a wave, so the aim is to take the positive AND the negative side of the wave. LEDs only works in one way !

Solder the coil

Once done, solder the 2 LEDs on the coil

And cut the mustach of those cute Leds ;)

Don't forget to put those small things in the garbage

So easy to let it down and it finishes in your foot or in your favorite pet's mouth.

Take the 3D printed parts and put the coil with the LEDs

inside, it should fit perfectly

Same with the top, normally no glue is required.

Take the screws ans bolts and assemble the parts so you would be able to fix it on your

take the magnet and put screw it on your bike.

Fix the light on your bike and adjust it so the magnet

passes in front of it, as close as possible, but it should touch it ! This is friction less system ! Feel free to make it touch if you want but that’s not the aim and it won’t last as long as expected.

Step 8 : Test it, just turning the wheel, ask someone to do

Test

it, just turning the wheel, ask someone to do it and check the angle which the light is is seen by cars.

Now you’re able to ride all night long with a light without

battery !

Show off on cycle path, take pictures, send me some, and share the « one bike one light » project to your friends and neighbours.

« Everyone should have access to batteryless bike light, this is my first step to upgrade the world »

Please pay it forward.
