Before workshop:
  * check all soldering iron bits are general purpose; purchase/replace as needed
  * do you want people to work in pairs (only need 1/2 the soldering irons)
  * check any additional materials/tools that could help:
    * resistor lead benders (300 yen each)
    * one spool of solder per soldering iron
    * etc...
  * test, test, test before the workshop
  * don't underestimate the time required

How to scale to many people?
  * have all workspaces ready, including tools
  * have component kits ready

How to improve the experience and reduce risk of mistakes
  * explain what they are going to build: summary of project
    * demo board = reference board while building
  * explain each component briefly, which also checks kits are complete
  * show schematic and explain point-to-point wiring used to connect parts
  * explain how protoboard and how point-to-point wiring works
  * explain how IC pins are numbered, polarity of IC, diode
  * give everyone a printed sheet with the schematic, resistor colour code, and the top and bottom (reflected) layouts
  * build from the layout diagrams, not from the schematic
  * explain soldering, especially safety: which parts get hot, avoid burning the cable, etc.
    * predict every mistake they might make and warn them about it
  * demonstrate how to make a good solder joint
  * demonstrate how to construct using camera and big screen
    * construct one part at a time
    * start with the lowest component (IC holder?) and work towards the tallest
    * solder the IC holder without the IC (put it in last, after checking power connections, etc.)
    * vise is probably not needed
    * TAs: check all students have connected their part correctly
    * do not leave students getting bored with nothing to do
