Electronic Equipment Protection Strategies for Sarayaku

A Defense System

The survival of teams in Sarayaku does not depend on luck, but on a disciplined protocol system. The failure occurs due to the accumulation of small oversights: a port left open, an unprotected connection, or a hasty temperature change.

This guide details the 5 Pillars of Technological Resilience to protect your communication, documentation, and work tools.

The 5 Pillars of Resilience

  1. Prevention (Tropicalization): Reinforce the equipment *before* it fails (sealing, mesh, caps).
  2. Storage (Dry Basis): Maintain a safe microclimate (Dry Box with hygrometer) for the equipment at rest.
  3. Operation (Acclimatization): Respect the 30-minute protocol to avoid "thermal shock" and condensation.
  4. Energy (Stability): ALWAYS use an Automatic Voltage Regulator (AVR) or UPS as an intermediary.
  5. Response (Triage): Knowing what to do (and what not to do, like using rice) when a disaster occurs.

Why this Guide?

The environment in Sarayaku (high humidity, rain, unreliable power grid) presents an extreme challenge. Humidity is a persistent and invisible enemy.

This guide is based on the full research document to provide proven strategies, from the simplest (Ziploc bags) to the most advanced (conformal coating), to ensure your critical technology keeps working.

The Triple Threat: Water, Humidity, and Corrosion

  • Liquid Water (Rain): It is the obvious threat. Direct infiltration causes immediate and catastrophic failures. It requires physical barriers (bags, cases).
  • Ambient Humidity (Vapor): It is the persistent and invisible threat. Humid air penetrates the casings and is absorbed into the circuit boards, waiting for a catalyst.
  • Corrosion (The Final Result): Humidity activates dust and salt in the air, creating a conductive sludge that corrodes copper traces and solder joints. This causes charging ports to stop working and the device to slowly fail.

The Silent Killer: Thermal Shock and Condensation

The most common and least understood failure in the tropics is not rain, but internal condensation due to temperature changes.

  • The Beginning: Condensation (dew) forms when warm, moist air (from the jungle) touches a surface that is *cooler* than the air.
  • The Critical Failure Scenario: The danger arises when moving a laptop or camera from a *cold* environment (a cool cabin at night, an A/C room) to the *humid heat* outside.
  • The Ruling: The mass of the equipment acts like "ice." Humid air condenses instantly on and inside the equipment (on lenses and circuit boards). A sealed case can then trap this moisture, creating a perfect microclimate for corrosion and fungus.

Biological Risks: Fungi and Insects

  • Fungi (Mold): High humidity is perfect for mold growth. The spores find an ideal home in the dust and moisture trapped inside camera lenses (causing permanent damage) and on circuit boards.
  • Insects (Ants, Termites): Electronic equipment (laptops, power supplies) generates heat, making them ideal hiding places. Entire colonies have been documented inside laptops.
  • The Damage: Insects cause short circuits. Their droppings are conductive and corrosive. They act as vectors, carrying moisture and mold spores into the equipment.

Active Prevention Protocols

Prevention is the 90% of work. These protocols are designed for every aspect of life in Sarayaku.

The Homemade "Dry Box"

It's the core of their strategy. Their goal is to create a safe microclimate (30%-50% humidity) for storing equipment when it's not in use.

  1. Container: Use a high-quality plastic container with a rubber or silicone seal on the lid. This is what guarantees that it is airtight.
  2. Absorbent (Desiccant): Use Silica Gel, Preferably with a color indicator (e.g., orange to green). It is reusable. When it changes color, dry it in the oven or over a flame (on a plate) until it returns to its original color.
  3. Monitor (Hygrometer): Install a small digital hygrometer inside. This is not optional. It's your "dashboard". If the humidity rises above 50%, you need to refill the silica gel.

Long-Term Storage (VCI)

For equipment stored for months (spare parts, radios), use VCI (Vapor Corrosion Inhibitor) Emitters. They are capsules that release a gas that adheres to the metal and blocks corrosion at a molecular level.

30-Minute Acclimation Protocol

This is the ONLY defense against "Heat Shock" (Risk Section). Follow this protocol religiously:

  1. BEFORE leaving From the cold room/cabin, turn off the equipment and place it inside your backpack or carrying bag.
  2. Seal the bag tightly. The bag now contains the cold equipment and, crucially, the *dry air* inside.
  3. Exit to the humid environment. DO NOT OPEN THE BAG.
  4. Wait 30 minutes. The bag acts as an "airlock", allowing the equipment's *temperature* to increase slowly.
  5. When you open the bag 30 minutes later, the equipment will already be at room temperature and the humid air will not condense on it.

Transport

  • Heavy Rain / Canoe: Use Dry Bags. They are 100% waterproof and float if they fall into the water.
  • General Transportation: Use Hard Cases. They protect against impact and are airtight. They function as a field "dry box".

The Danger of "Dirty" Energy"

Power from generators or the local grid is unstable. The danger lies not only in power outages, but also in voltage fluctuations (spikes and drops) that can damage chargers and power supplies.

The False Security of the Surge Protector

A simple surge protector power strip is INSUFFICIENT. It only protects against instantaneous spikes (lightning), but IT DOES NOTHING against voltage drops (undervoltage) or sustained overvoltage, which are the most common generator problems and "starve" or "cook" your equipment.

Solutions (Minimum vs. Ideal)

  • Minimum Essential: Automatic Voltage Regulator (AVR). Also called a "Stabilizer". It monitors the voltage and "raises" or "lowers" it to deliver stable power to your equipment.
  • Gold Standard: UPS / Uninterruptible Power Supply. A UPS combines a surge protector, an AVR, and a battery. It provides complete protection, isolating your equipment from "dirty" power.

Electrical Protection Matrix

Protection Suppressor (Simple) Regulator (AVR) UPS / No-Break
Peaks (Lightning) Yeah Yeah Yeah
Voltage Drops (Sags) NO YEAH YEAH
Sustained Overvoltage NO YEAH YEAH
Power outages NO NO YES (Battery)
Recommended Insufficient Minimum Essentials Ideal

Advanced Physical Protection ("Tropicalization")

For critical equipment, you can apply permanent physical modifications to "tropicalize" them.

  1. Conformal Coating:

    This is the most advanced defense. It's a chemical spray (acrylic or silicone) applied directly to circuit boards (PCBs). It creates a waterproof barrier that seals the electronics against moisture, corrosion, and fungus. It requires disassembling the equipment and masking (covering) the ports and connectors before application.

  2. Port Covers:

    A low-cost, high-impact solution. Use silicone or rubber caps to seal *all* unused ports (USB, HDMI, audio). This blocks moisture, dust, and insects from entering.

  3. Insect Screens:

    Laptop and power supply vents are highways for ants. Attach fine mesh screens (like mosquito netting) over the vents to block insects. Regular dust removal is necessary to prevent overheating.

Emergency Protocols!

If an accident occurs, what you do in the first 10 minutes is critical.

Triage: Wet Equipment (Immersion/Rain)

  1. TURN OFF IMMEDIATELY!

    If the unit did not turn off automatically, turn it off. Do not press any other buttons. This stops the electrolysis that causes corrosion.

  2. REMOVE THE BATTERY!

    If it has a removable battery (camera, radio), this is the MOST IMPORTANT step. Cutting off the power is vital.

  3. Drain and Dry on the Outside:

    Turn the device upside down and gently tap it against your palm to drain any liquid from the ports. Thoroughly dry the exterior with a cloth.

  4. Absorb (Correctly):

    Place the device in a tightly sealed container or bag with plenty of packets of Silica Gel. This aggressive desiccant will absorb internal moisture.

  5. Wait 48-72 hours:

    Patience is key. Don't try to turn it on "just to see if it works.".

  6. NEVER use heat:

    Do not use a hot hairdryer, direct sunlight, or fire. Heat damages components and "cooks" corrosive minerals on the plate.

Why Rice Is a Dangerous Myth

The advice to "put it in rice" is ubiquitous and actively harmful. Use it only as a last resort if you have NOTHING else.

  • Inefficiency: Rice is an extremely poor moisture absorbent. It cannot draw out trapped moisture from inside a device. Silica gel is 10 times more effective.
  • The Real Danger (Waste): The problem isn't water (H2O), it's the minerals and salts dissolved in it. When water evaporates, these residues are left behind; they are conductive and highly corrosive. Rice does nothing to remove them.
  • Pollution: Rice introduces powder and starch in ports and openings. This starch can absorb future moisture and promote mold growth, worsening the problem.

Corrosion Cleaning

  • Isopropyl Alcohol (IPA 90%+):

    Use a soft toothbrush and rubbing alcohol to clean mold, water residue, or general sulfation from circuit boards (PCBs). It's safe and evaporates quickly.

  • White Vinegar:

    Use it *specifically* for green/white corrosion (sulfation) caused by spilled alkaline batteries. The acid in the vinegar neutralizes the battery base. Clean afterward with a little IPA.

  • Contact Cleaner:

    A special spray to remove oxidation from USB ports, audio connectors, and charging pins that are not working properly.

Response to Insect Infestation

  1. NO spray liquid insecticide inside the equipment.
  2. Turn off and unplug the equipment.
  3. Place a ant bait (in gel or liquid form) *near* the device (not on it). The goal is to attract the colony *away* from the device.
  4. Once the infestation is gone, open the equipment (if possible) and clean it thoroughly with compressed air and isopropyl alcohol to remove corrosive debris.

Specific Tips by Team

📱 Cell phones and tablets

  • Priority #1: Always use waterproof covers (like Ziploc bags or diving cases) when outdoors or near water.
  • Clean the charging port (USB-C, Lightning) regularly with a wooden (non-metallic) stick or a dry toothbrush to remove lint and dust.
  • Never charge the device if you receive a "moisture detected" alert. Dry it with air (a blower) and wait.

💻 Laptops

  • Priority #1: Always transport it switched off (not just suspended or in hibernation).
  • In your workplace, place it on a base or stand to improve air circulation underneath and prevent it from absorbing moisture from the table.
  • Don't eat near your laptop. Crumbs attract insects.

📷 Cameras and Lenses

  • Priority #1: Dry box storage with hygrometer and silica gel is mandatory to prevent fungal growth on the lenses.
  • When saving, remove the battery and memory card.
  • Never change lenses in the rain or in very dusty/humid environments.

📻 Radios and GPS

  • Remove the batteries when not in use for long periods to prevent sulfation of the contacts.
  • Clean the metal contacts of the battery and charger with contact cleaner or isopropyl alcohol if you see corrosion.
  • Apply a small amount of dielectric (silicone) grease to the rubber seals of the battery compartment to maintain a watertight seal.

🔋 Chargers and Battery Banks

  • Priority #1: NEVER connect them directly to a wall outlet or generator. Always connect them to a Automatic Voltage Regulator (AVR).
  • Don't leave them on the floor.
  • Use power banks as intermediaries: charge the bank from the unstable grid, and then charge your cell phone from the clean energy of the bank.

💡 Solar Panels and Generators

  • The energy from these systems is inherently "dirty" and unstable.
  • Charge deep cycle batteries (car/marine batteries) with this energy, and then use a pure sine wave inverter connected to that battery to charge your sensitive equipment.
  • Or at the very least, use a AVR between the generator/inverter and its equipment.
