Materials

Popular

  • Aluminum Alloys (6061, 7075)
  • Stainless Steels (306, 316)
  • Steel (A36)
  • Plastics (LDPE, HDPE, PVC, PET, PC, PP, PS)
  • Polyester, Nylon

Attributes

  • Tensile Strength vs Yield Strength vs Shear Strength
  • Hardness
  • Thermal Expansion
  • Thermal Conductivity
  • Electrical Conductivity

Fabrics

  • Fabrics are made by weaving thread in an interlaced pattern.
  • Artificial threads such as polyester can be made in custom lengths, because the production process involves feeding polyester chips into a hopper then melting and extruding the material through tiny holes.
  • Natural threads such as cotton have organically-occurring fibers of a limited size. In this case the production process twists cotton fibers together in order to create long thread.
  • Fabrics become stronger through compression and twisting during the production process.

Safety

  • Sharpness. Modern bed-frames still have sharp corners that hurt people as they walk close by.
  • Brittleness. Normal glass is prone to shattering into a dangerous, potentially deadly hazard that is hard to clean up.
  • Slipperiness. Many liquids will cause people to trip; especially dangerous near hard surfaces and sharp objects.
  • Mass. People will commonly drop all sorts of objects from waist and elbow height, risking their feet.
  • Ingestion.
  • Out-gassing
  • Melting point and boiling point
  • Gas-state toxicity
  • Chemical reactivity

Electrical

  • Standoffs - Critical mounting separator between a circuit board and its mounting plate.
  • PCB Milling
  • PCB Etching

Controls

  • Industrial Control Panel
  • Wire ducts, Tags
  • Ferrules - Critical connector between the end of a wire and a device input hole for industrial applications. Essential for operational reliability.
  • PWM (Pulse Width Modulation)
  • PID Controller

Construction

Shelter

  • Primary purpose: warmth, safety from bugs and animals
  • Summary: Shelter, air, energy, heating, cooling, internet, noise, bugs, neighborhood, area.
  • Check leaks and holes. Walls, window mesh, baseboard, faucets, ceiling.
  • Check indoor humidity. Ideally 30% - 50%. In excess moisture, use dehumidifier against fungi and rot. In lacking moisture; use humidifier for healthy skin and mucous membrane (boosts immune system strength).
  • Check electrical outlets. Match against region's expected voltage and max current standards. Voltage during use should not fluctuate. Ground must be connected. Excess current should trigger an easily accessible circuit breaker.
  • Check available internet and other telecom services. Prepare well in advance of moving in.
  • Check telling signs of bedbugs, roaches, fungi, and other polluting organisms. Search for spots, excrement, powder, and strange particles.

Food

  • The human body needs the right balance of healthy nutrients.
  • Macronutrients are vital sources of energy (calories), comprising carbohydrates, fats, and proteins.
  • Micronutrients are important for specific bodily functions, comprising vitamins and minerals.
  • Macronutrients must be consumed regularly (daily).
  • Micronutrients are stored up in the body, hence can be consumed more sporadically (based on the micronutrient)- as long as the average amount is sufficient.
  • Eggs, Oatmeal, Beans, Honey, Peanuts
