You will find in
this page some DIY (Do It Yourself) electronics projects and some other
things. Feel free to ask for
schematics & or source code. |

Gearbox Indicator |
|
|||||
|
Aim: Realize a Gearbox indicator (1
< Engaged Speed < 6) Engaged speed is displayed on a LED bargraph.
It exists on some
motorbikes (for instance injection suzuki bandit) a wire providing a voltage
depending on the engaged gearbox speed. This voltage only needs to be sampled
by an analog to digital converter. The program is running onto a dsPIC µC
from Microchip. |

|
Automatic Cat
Feeder |
|
|||||
|
Aim: Realze
an Automatic cat feeder. The feeding times and the number of feeding times
are choosen by the user. Keywords: dsPIC,
servomotor (PWM command), optical fork, LCD, keyboard, interruption, RTC
clock.
When powering up,
the user has to choose (by typing on the keyboard) the number and the times
of the feeding times. The program (running onto a dsPIC) compare the actual
time (RTC with a 32kHz Quartz) with the memorized feeding times. If it is
feeding time a servomotor (driven by a transistor and a relay) is rotated in
order to free the food looked in some PVC tubes. An optical fork (issued from
an old computer mouse) is in charge to manage if the tank of food is not
empty. Some messages are
displayed on the 4x20 LCD display (actual time, next feeding time, state of
the food tank …) |

|
Laboratory Power
Supply (ATX PC modified Power Supply) |
|
|||||
|
Aim : Realize a Laboratory Power Supply
issued from a modified (load resistance & fused protections) ATX PC power supply. This Power supply can
provide 3.3V / 5V / 12V / -12V voltages.
