A lot of electronics measurements use the same equipment: power supply, function generator, oscilloscope.. It makes sense to consolidate this into a single, fixed measurement platform that is already in the workshop and is complete with relevant cables and such.

Current todo

(not necessarily in this order)

  • Find or build an enclosure
  • Figure out what to put in it
  • Think out how to keep the dust out when rig is not in use
  • Order what we still need
  • Put it together
  • Create documentation sheets (as described below)
  • ???
  • PROFIT!

Enclosure

I (smeding) haven't thought about this too much yet but a reasonable idea seems to be a trolley of some sort (or something without wheels) with separate shelves.

Contents

  • Power supply
  • Oscilloscope
  • Function generator
  • Bench-top multimeter
  • Logic analyzer
  • Timer?
  • Relevant cables:
    • Banana-plug leads, assorted colours - we can manufacture these
    • Banana-plug to crocodile clip leads, red & black - we can manufacture these
    • Multimeter probes, 1 red / 1 black - we have these
    • BNC <-> BNC (50 ohms, semi-decent coax) - to be acquired (possibility)
    • BNC <-> crocodile clips - to be acquired (possibility)
    • BNC t-junctions - we have these
    • 'scope probes - we have these
  • Documentation - both simple, single-sheet summaries for beginners (see below) and full manuals where we can find them.

Documentation

The main idea for this part is to write up basic one-sheet introductions to the various instruments at our disposal. Necessary information would be (order isn't fixed):

  • What the instrument does (measure voltage, produce a voltage, etc.)
  • When to use it
  • Limitations
  • A walkthrough for doing a measurement (for a 'scope: from "attach probes to device and circuit" to getting the image you want)
  • Issues/features specific to the instruments at RevSpace

Devices to cover:

  • Power supply
  • Multimeter
  • Oscilloscope
  • Function generator

Todo for this part:

  • Writing
  • Graphic design, pictures, any artwork (diagrams?) - nothing too fancy, just enough to make it clear
  • Put them online and print them
