Read Device Safety from

  1. NEVER take things apart when plugged in!
  2. remove the batteries before the deassembly
  3. Look out for large capacitors like this. Let me know if you see one or are unsure
  4. If you feel unsafe performing any aspect of the taking apart process, stop working and ask for advice
  5. Avoid taking apart:
  6. Digital cameras with flash might contain some high voltage capacitors
  7. NEVER plug in AC electronics once you take them apart
****if you suspect a high voltage capacitor and really need to work with one, here is a safe way we can discharge the capacitor. or here

Things to think about when you are working with found electronics:

  1. Is it a working device?
  2. Does your electronic use AC or DC?
  3. What is the brand and model number?
  4. Can you find a service manual or schimatic online?
  5. What is the voltage this devise uses?
  6. Does it use a power adaptor or battery? (DC)
  7. What parts can I use?

Useful things to look for

Class assignment: Show and tell

  • When was it made?
  • Where was it made?
  • What part does what?
  • Favorite part?
  • Useful part?
