The Solder:Time Watch Kit is a Maker Shed favorite for several reasons; it’s simple, it’s functional, and it looks great!  The watch comes unassembled and includes a laser cut acrylic enclosure and wrist strap. The bright red LED display is driven by a PIC16 using a Dallas DS1337+ RTC chip for accurate time keeping. The time is displayed on demand for increased battery life but can be jumpered for always on use. If you’re looking for a great conversation starter, this is it! It seems that every time I wear mine in public people can’t help but ask me where I got it. Of course I tell them “I made it!”

I am the Evangelist for the Maker Shed. It seems that there is no limit to my making interests. I’m a tinkerer at heart and have a passion for solving problems and figuring out how things work. When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.

    A pocket watch option would be cool.

    Looks amazing.. love it! So if you want to build in a timer as well would that be crazy hard or doable?

  • Michael Castor

    Completely doable – but the firmware is written in assembly so you’ll have to use Microchip’s MPLAB to modify the code and recompile new HEX files.

    The Solder:Time 2 ( is Arduino based and would be much easier to reprogram. It even has a buzzer to sound when the countdown finishes.
