Hello guys. I usually visit this section of the forum to see your designs on lights.
I have seen many fine buildings, and retained a lot of ideas here.
So I decided to share my latest project with you, here are some of the features:
20 x Cree XP-G
Microcontroller: Atmel 2560 (with Arduino bootloader)
Driver Hyperboost (modified to 1.6A max.)
EM-406A GPS Receiver SiRF star III
2 batteries 4s 4500ma
2x 30x30mm Fan Sunon maglev
2x current sensors:
16x2 character LCD
A humidity sensor
2x capacitive sensors "IQS127D" (for buttons)
Lm35 temperature sensors 3x
20 cree xp-g. Controlled by PWM, currently has four fixed light levels .. but is then to vary automatically as the speed of the bike and ambient light.
GPS receiver (for now just to know the altitude, speed, and time)
Information on ambient , LED and driver(mosfet) temperature. Information relative humidity and ambient light.
Read the voltage of individual 8 cells, the input and output voltage on driver, and the current input and output of the driver (for future calculation of efficiency and autonomy in the driver).
Capacitive Buttons (IQS127D chip), illuminated with RGB LEDs individually controlled by the 8-bit PWM. (all DIY)
(color of the left button depending on battery power, and the right side as the front light mode selected)
Heatsink for servers:
Driver with a dedicated box and sink .. the driver is inside the light and is
ventilated by two fans along with the LED's:
Testing the GPS module:
Some tests in the wild:
I know that the light is very ugly
I would like to hear your opinions and ideas to improve the light. Or ideas to add new functions to the software.
