It is designed to provide a humorous and interesting view of the metric system and how it might apply to timepieces. The metric clock may be used to tell time in the metric system should metric time be considered or implemented. The metric clock has a standard clock movement with 3 rotating hands. Time is told by the position of the hands relative to each other or relative to the clock face. Description METRIC CLOCKThe metric clock is simply a clock face divided into 10 increments. At the top of the face is the number 10 and the number 5 appears at the

Introduction: Tempus - a Metric ClockI was asked to build a metric, or decimal clock, as they are not readily available commercially. Metric time, or French Revolutionary time, divides the day into decimal units. A day has 10 hours, an hour 100 minutes, and a minute 100 seconds.(If you do a search, you will discover so-called metric or decimal clocks for sale. But be careful - these clocks have what looks like a metric face (10 hour markings and numbering), but use a standard 12-hour mechanism, with 60 seconds per hour and 60 seconds per minute. Such a clock is not a metric clock at all. I have not been able to find a true metric clock for sale, other than antiques. If you find a modern one, please let me know.) I was asked to build an analog metric clock with hour, minute, and second hands that would run on Great Britain mains power. I have built clocks using 1 RPM synchronous motors, which run in step with 60 Hz 120v power. My first thought was to use a 50 Hz synchronous motor. But doing the math reveals this to be problematic. There are 60*60*24 or 86,400 seconds per day in standard time, but 10*100*100 = 100,000 seconds per day in metric time. So a metric second is .864 of a standard second. With 100 metric seconds per revolution of the seconds hands, that makes 86.4 standard seconds per revolution, 60/86.4 = .694444444 RPMs. Not easy to find a synchronous motor like that.What kind of motor could operate accurately at an unusual speed? I decided a stepper motor would work. My first thought along this line was to use one motor at the proper RPM for the seconds hand, and gears to drive the minutes and hours hands. But a divide by 100 gear train would require 4 sets of wheels and pinions to be compact. I decided to use a separate stepper motor for each hand.SuppliesMSP 430 Launchpad - Texas Instruments28BYJ-48 5v stepper motor with ULN2003 Driver Board - eBaypushbutton switch, SPST.1 uF ceramic capacitorUSB power supplyGears -

Soldered directly to the pushbutton's leads.Ordinarily I would get circuit boards made, or solder a breadboard, but as this project was a one-off and the Launchpad inexpensive, I just used it in the final clock. I used a universal USB power adapter to power the clock once development was finished and the USB cable was unplugged from the host PC. The adaptor has snap-on prongs for US, GB, and other countries' power.Step 3: Clock Body and HandsI design the clock face and body using Carvewright's Designer software and machined them using the Carvewright CNC machine. I used 3/4" MDF for the parts. The hands were similarly designed and machined out of maple. Hobby brass tubing was used for the shafts. This tubing is sized such that the next large tube slides nicely over the smaller diameters. I used smaller diameter tubing for the seconds hands, and progressively larger for the minute and hour hands. I got some hobby gears sized to fit the metric shafts of the stepper motors. The diameter was close enough to standard English tubing size to also fit onto the hands shafts. I soldered larger-diameter tubing onto the smaller diameter tubing to fit the gears. I designed and machined motor mounts with the Carvewright. I added some spring-loaded shoes to the gears to prevent undesired movement of the hands due to gear backlash in the stepper motors and the gears that I added.Step 4: SoftwareThe basic function of the software is to step the seconds (and minutes and hours) motor at the correct rate for a metric clock. One of the microcontroller's timers is use to trigger the next step. As already mentioned, I used a 32.768 MHz watch crystal as a timebase for the MSP's ACLOCK. With a timer set to this clock, it counts up once every 1/32,768 seconds. So, how many timer counts between steps? With 32 steps per motor rev, the not quite 1/64 gear set in the motor, .864 seconds per metric second, 100 metric seconds in a full rev of the second hand, the math was done with a spreadsheet
