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.
