Build your very own Coordinated Mars Time (CMT) binary clock! This clock is designed to keep Coordinated Mars Time, which runs about 2.7% slower than Earth time. Wikipedia has a good article which explains Mars timekeeping: https://en.wikipedia.org/wiki/Timekeeping_on_Mars

This clock looks cool on an desk or table and makes a great conversation piece. Can be powered by a USB connection from a computer, USB hub or even a USB charger! The time is set with a simple on-board touch sensor.

Once built, you may set the time on the clock using this tool: http://jtauber.github.io/mars-clock/

Everything you need to build your own working Mars time binary clock!

• 1 - High Quality Lead-Free Professionally Printed Circuit Board 2"x2"
• 1 - ATTINY44 Microcontroller
• 20 - Red LEDS
• 2 - 25 pF Capacitors
• 1 - 16 Mhz Crystal
• 6 - 75 ohm Resistors
• 1 - Mini USB connector
• 1 - 2 Pin Connector (touch sensor)
• 1 - Assembly and Operation Instruction Sheet

Touch the sensor for 2-5 seconds to synchronize the clock to the nearest minute (forwards and backwards in time). Touch the sensor for more than 5 seconds and the time will advance, first through the minutes, then through the hours.

Each part is clearly labeled on the printed circuit board for easy assembly. Soldering is required. All of the components are standard easy-to-work thru-hole type. Paper instructions for assembly and operation are included with each kit.

A great kit for a great price! This would be a fantastic parent child project.

It is quite easy to integrate this into your own project. The LEDs can be wired from the board to your own housing for a custom 24-hour clock of your own design.

Think you can't build it? Think again! I have an instructable made with step-by-step pictures to guide you along the way!

This entire kit, hardware and firmware is designed and packaged by myself, a professional engineer, in the USA. I would be happy to answer any questions you might have.

I almost always ship the same day or the next day an order is placed.

I also offer a combined shipping discount if you order more than one kit! Just add them to your cart to see the shipping price.

Please look in my listings for other kits I have designed.

Thanks so much for looking and have a great day!
