The Multimeter Clock consists of three multimeters, the first meter displays hours, the second displays minutes and the last displays seconds. A 16F628A PIC microcontroller keeps track of time and outputs a calculated current to each meter to display the current time. The meter shown above is one example of what you could make to show off your Multimeter Clock. Please note that the kit does not include the clock housing or the meters. If you have a CNC machine please see the project page for the CNC files to create your own Simpson 260 Multimeter clock case.
Details for the Multimeter Clock can be found here.
Please note that this project is advanced since you will need to construct the entire circuit based on the schematic on the project page.
