Introduction: Solar Charged-Microcontrolled Bike Light With Power LEDS
Here is the first complete product project of endtas. It is LED headlight for bicycles. It has got two 1W leds, one with a wide angle and the other with a narrow beam angle lens. The white ABS plastic prototype is actually printed by an UP printer :).
The wide lens is a bit turned towards the ground to light up nearby ahead and the other straight ahead for greater distance lighting.
This is a microprocessor controlled inttelligent light with 9 lighting modes.
1. Double 5mm led flash
2. Double 1W leds triple flash
3. Double 1W leds continuous flash
4. Continuous power 1st grade + flash/2seconds
5. Continuous power 2nd grade
6. Continuous power 3rd grade
7. Continuous power 4th grade
8. Continuous power 5th grade
9. SOS signal flash mode. Flashes S.O.S distress signal with 2 1W LEDs.
The light circuit is designed to work with two Nokia cell batteries but the prototype is made by using 3AAA type batteries, generating 3.6V aprox. The product can run for days at the minimum power setting and more than 3 hours at max power.
There are many instructables online about how to build circuits on prototype boards, soldering, 3d printing etc so I'm skipping those. The hex file for the project can be downloaded from http://www.endtas.com/solar-charged-bicycle-light/.
We have a be nice policy.
