Electronics
Joule Thief -
extract the last bit of energy from a 1.5 VDC cell to light a LED with
this simple circuit
Supercapacitor -
Capacitors rated in Farads, not MICRO-Farads. Extreme capacity, battery
replacement, almost unlimited charge cycles.
Arduino - Microcontroller / CPU with imaginative
uses
ESP8266
- Wi-Fi Microcontroller -simpolifies Arduino interface for IoT
Ceramics
Blades - Zirconia blades rated 8.5 MOH opposed
to steel at 6.5 MOH. Sharper, longer but more brittle
Fire Starter - Zirconia scraper superior to
hardened steel.
Plastics
Kevlar,
Dyneema,
Spectra, etc. - Ultra High Molecular Weight
Polymer (UHMWP) - Lighter, stronger than steel
Sugru / self vulcanizing Silicone
tape - Silicone based self vulcanizing putty and
tape
Polymorph
/ FORMcard
- Low melting point thermoplastic polyester (160 F / 60 C degrees)'
moldable by hand.
Magnetics
/ Rare Earth
Neodymium
magnet
- Ultra strong Rare Earth magnets
Ferrocerium
- Rare Earth misch metal used for "flints" and sparkers
