Using Natural Cycles and Environmental Triggers
Sunlight-Driven Changes: Light-Sensitive Switches (If Available): If you have a solar cell and a small photodiode, you can create a rudimentary day/night sensor to open blinds or activate lights.
Wind and Rain Power: Wind-Activated Chimes or Levers: Let wind push a vane connected to a release mechanism that scoops water or shifts a covering at set wind speeds.
Rain Collection Slopes: Rain hitting a tarp can gradually fill a counterweight, eventually pulling a cord that lifts or drops something at the rain’s onset.
Observe nature: termite mounds maintain stable internal climates. Mimic their methods—like layered insulation or small vents—to passively regulate shelter conditions.
Simple Mechanical Automation
Thermal and Solar Mechanisms: Solar-Heated Airflow: Black-painted surfaces heat air, causing airflow that can drive small wind-driven rotors connected to vents or fans.
Use household items (clothespins, springs, hinges) to create mechanical triggers. Ingenuity trumps high-tech in low- resource conditions.
Leveraging Any Available Technology
If Partial Power Survives: Solar-Powered Controllers: A small solar panel can power a microcontroller (like a Raspberry Pi or Arduino) programmed pre-collapse to run timers or sensors.
Offline Timers and Relays: Mechanical timers or battery-powered switches can regulate lights or pumps.
Repurposed Devices: Old Wind-Up Timers (Kitchen Timers): Use them to release a latch at set intervals for drip feeding animals or adjusting shutters. Thermostats and Thermometers: Even basic bi-metallic strips (found in old thermostats) expand and contract with temperature changes, switching systems on/off.
Automation Techniques: Practical Notes
If you have a small supply of magnets and metal switches, create a reed switch system to turn on lights when doors open automatically.
If greenhouses are part of your plan, rig a thermal-triggered vent using a wax-filled cylinder that expands with heat, pushing open a shutter.
Attach a small wheel to a stream’s flow—this waterwheel can lift a tiny lever that pours feed into an animal trough at intervals.
Combine multiple triggers: a morning temperature rise triggers a bimetal strip bending, opening a vent, and letting fresh air in without manual labor.
Home Automation: Practical Notes
Repurpose solar garden lights indoor: charge them by day at a window, bring them inside at night as free lighting.
Treating Resources as Currency
Local Conditions Matter: A liter of water may be cheap in rain season but priceless in drought—adjust valuations as conditions shift.
Smart Blinds, Natural Language Voice Assistants, and More
Smart Blinds/Shades: Light and Heat Management: Adjust blinds remotely to control solar gain, keeping your home cooler or warmer and conserving energy.
Adapting to a Barter Economy
Negotiation and Price Discovery: Start Low, Find Fair Midpoint: Don’t reveal all your willingness—if you have multiple water containers, first suggest a smaller trade. If they push, gradually increase your offer.
Home Automation
In a scenario of declining infrastructure and uncertain utilities, a well-prepared home automation system can offer substantial advantages. Even if external power grids fail, having a partially self-sustaining, energy-efficient smart home grants you a measure of comfort, security, and convenience. By integrating lighting, heating, ventilation, and appliance control into a cohesive system, you save energy, reduce manual tasks, and maintain a stable, habitable environment. Although full automation might be challenging after a collapse, setting it up pre-collapse ensures you can leverage technology to survive longer and with less labor.
Motion Sensors: Automatic lights trigger only when needed, preventing wasted energy.
Moisture Sensors in Soil: Only water when needed—conserves water if city supply fails and you rely on rain barrels.
Automate a reminder before automating a decision
A low-risk starting point is a visible indicator showing when a consumable reaches a chosen reorder point. A mark on a storage bin or a dated card can prompt a person to check the remaining stock. The person still decides whether the item is needed and whether the record is accurate. Compare the reminder with actual use for several cycles and adjust the trigger if it regularly arrives too early or too late. Simple automation should expose its state and be easy to override. Hidden mechanisms that nobody understands can replace a small routine task with a larger maintenance burden.
