Lab A3 Teardown

Part 1:
  1. Get a toolkit (if you don't already have one).
  2. Review the some teardowns at iFixit and send me an email with a link to your favorite one, with a short explanation of why it's your favorite. Be sure to venture beyond the lists of "Recent" and "Popular". For some examples, see
  3. Watch the following video (a teardown of an Anritsu spectrum analyzer from Mike's Electric Stuff; see his YouTube channel for more videos).

Part 2:

Commercial Electronics Autopsy: Take apart a piece of commercial electronics (provided). Take pictures, study construction techniques, draw a block diagram, write a bill of materials of major parts (top ten), and find some data sheets, but don't draw a schematic. Make a list of the major components; the main integrated circuits are important, of course, but don't overlook interesting examples of passive components, sensors, connectors, switches (and other controls), internal cable assemblies, heat sinks, mechanical elements, etc. Deliverables (as a web page):
  • Link to service manual (if found)
  • Basic test results showing operation (or non-operation)
  • Pictures of the disassembly and the insides
  • Block diagram of the system
  • Bill of materials of ten major parts, with date codes and datasheets
  • Discussion of the mechanical design, including functional and decorative elements
  • Short presentation for informal show-and-tell session
If your item has an FCC ID code on it, be sure to check out if any of the FCC filings are public at
Extra credit for salvaging and reusing some interesting part from your autopsy (for example: motors, sensors, LEDs, switches, fans, etc.).
