Welcome to the Restart Wiki!

This is a place where those of us in the Restart community with experience and skills in mending appliances and gadgets can share them with those who are starting out, or whose own knowledge lies in different areas.

What it isn't: It isn't going to show you how to fix a particular make and model of device, which we leave to the various fix-it sites and many disassembly videos. You can also get help with a device on social media using #SOSRestart. Here, we concentrate on basic and widely applicable principles.

Who it's for: It's aimed at anyone with a curiosity about how things work and how to fix them. No prior knowledge is assumed. In the spirit of sharing knowledge as widely as possible, everyone is welcome to read it. To contribute, just become a volunteer Restarter in your community and contact us.

Like any wiki, this one is work-in-progress. Pages referenced below in red don't yet exist but are projected.

• AC and DC - what's the deal?
• Electronic components - recognition, failure modes and testing:
  • Basic electronic components - Resistors, capacitors, inductors and transformers, and quartz crystals.
  • Active components - Diodes and rectifiers, transistors, and integrated circuits (ICs).
  • Passive components - Switches, push-buttons and connectors.
  • Protection components - Various devices for over-voltage and over-current protection. Fuses are only the beginning!
