1. keep the schematics simple
1.1. remove the ignition management module because it is very complicate to make all the things work and it is more simple to figure out where are the problems.
1.2. remove the stepper motor controller module (because i use a servo motor instead)
1.3. remove any other unused module (relays, leds, connectors, etc...)
2. isolate or change the metallic box because the rain it is a problem
3. replace all the connectors and solder the wires on the pcb to avoid any problem with connectors.
4. increase the clock tick interrupt from 1/4us to 1/8us (or 1/16us)
In the following pictures you can spot some issues. The rain cause a short circuit and the pcb was damaged in some points.
The three places where the pcb was damaged in the version2:
The "salt like" substance from the rain:
change the make of your box to some type of ABS plastic, and the use of Conformal Coating can make it more resistant to moisture.
RăspundețiȘtergereYes, i will use a new box, from metal. All the wires will go out through small holes in the bottom of the box.
