This is an electronic digital caliper to computer (RS-232) interface. This will work with the inexpensive calipers, micrometers and height gauges that are typically made in China. The connector on the measuring instrument will have 4 pins, and the owner's manual will typically describe the output as 24 bit 90 kHz synchronous. This does not work the name brand instruments - Fowler, Mitutoyo, Brown & Sharpe, etc.
GraffitiWriter is a tele-operated field programable robot which employs a custom built array of spray cans to write linear text messages on the ground at a rate of 15 kilometers per hour. The printing process is similar to that of a dot matrix printer. GraffitiWriter can be deployed in any highly controlled space or public event from a remote location.
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

Every object and surface in our environment has a whisper; subtle tremors and vibrations that are usually undetectable to the human ear, produced by the activity and movement of daily life. What if these sounds were audible? OTTO (Greek for 'ear') picks

The practical work supporting Chapter 4 introduces you to using an oscilloscope to display V/t graphs. This is a very powerful technique for investigating and understanding circuit behaviour and for correcting circuit faults.
