Everything Sildr and technical.

1.0 and 2.0 are legacy, and some relevant documentation can be found in /legacy. Keep in mind it's mostly in Norwegian.

Electrical System v3.0

Overview Illustration (click on image to open Figma):

The system is split in two parts:

1. Base system
2. Optional data logging system (requires the base system)

Base System

Simplified circuit diagram (click on image to run simulation):

Image may be outdated

• Behavior can be controlled with an MCU, and has an analog fallback
• Relay represents the solenoid valve
• Voltmeter is a digital in pin, registering 0V as button presses
• Logic sources are digital out pins
• Resistor connected to pin 7 and 6 on the 555-timer can be changed out for a potentiometer to manually set timer on-site

Simulated Prototype Circuit (click on image to run simulation):

Image may be outdated

• Simulation requires an Autodesk account (you can use your google account)
• Lightbulb represents the solenoid valve

Prototype Components

• 1x 555-timer
• 3x nMOS Transistor (MOSFET)
  (FQP30N06L 60V LOGIC N-Channel MOSFET)
• 3x 1k resistor
