Safety

Last updated September 17, 2026

Much of the work documented on this site is dangerous:

  • Electric/electronic devices often connect directly to mains power (120/220VAC).
  • Nixie and neon displays need 170VDC or more.
  • Power supply components such as filter capacitors often hold a charge long after the supply has been removed.
  • Older devices can contain toxic materials like mercury, asbestos, beryllium oxide, or radium paint.
  • Mechanical parts can be under extreme tension from springs or weights.
  • Lithium cells can vent and burn.
