Description

The SparkFun BigTime watch kit is a geekishly stylish digital watch with a NATO style watch-band and a slick acrylic enclosure. If it seems familiar, that's because it's essentially our open-source branch from the SpikenzieLabs' Solder:Time kit. The heart of the kit is the much venerated ATMega328 using a 32kHz clock-source to keep time. To check the time, just press the button on the side of the watch and it pops up on a 4-digit 7-segment LED display. Thanks to some low-level hackery, the ATMega is running at super low power and should get an estimated 2 years of run time on a single CR2032 coin cell!

The BigTime is a through-hole kit with a low parts-count, so it makes a great project for beginning solderers. After you've finished soldering together the PCB, simply stack the acrylic pieces around it and screw them together with the included screws. Once that's done, pop in the coin-cell battery and go show off your nerd bling!

Did we mention that the watch kit is super hackable? An FTDI header is broken out to the side of the board and the watch-firmware is running on top of a bootloader! This means that all you need to do to add your own code is to open up Arduino or Wiring and select "Arduino Pro or Pro Mini 3.3V/8MHz w/ ATmega328" as your board.

This version of the watch uses brass inserts for a more secure enclosure. It also uses a new NATO style strap.

Product review & video

hello Dave here again with smartphone electronics today we're gonna be talking about how to construct your very own big-time watch kit this is a very simple watch it's got a little red circuit board in it with an atmega328 processor it keeps decent time but it's very very stylish so this is a kit that you can actually assemble yourself and we're gonna be using the learn to solder big-time kit which comes with a soldering iron solder the kit itself and a couple of other tools to help us along the way first we've got safety glasses and we have some nippy cutters which are very handy when snipping leads we have the actual soldering iron we have the kit itself that contains all the components that we're gonna be working with you have some solder to go with the iron if some solder wick which hopefully we won't need but if we mess up if we need to you know go back in step this will be very he
