Hello! Welcome to another Other Machine project tutorial! I’m Sam DeRose, a former Other Machine Co. Summer Intern. I created The Nerd Watch last summer while working at OMC.
The Nerd Watch displays the time in binary when the button is pushed. The watch shows the hour and minutes by flashing two LEDs in sequence to represent two 4-bit binary numbers (in big-endian format). Here’s a great description of how to read binary numbers.
In this Instructable, I’ll show you how to build a Nerd Watch from scratch with a few electronics components, and an OMC Othermill.
This Instructable presumes you have previous experience working with surface mount electronic components, and that you are no stranger to a multimeter or soldering.

F*watch is a fully open electronic watch project featuring an integrated GPS receiver.
The development started at CERN as an after-work project to make a special present for a retiring colleague who likes hiking and timing.
The full design (electronics, mechanics and software) is available under free licenses and the design is exclusively made with free tools.

Elia wrote an article detailing his binary wrist watch project:
I have just finished my binary wrist watch project (well, the new revision anyway). I was surprised at how small I was able to make it compared to last time.
I chose to go with the “super-yellow” color LEDs as they fit the purple OSHpark PCB very nicely. The biggest challenge was actually making a good looking wrist band for the watch. I originally intended to use a design like this but it turned out that due to lack of enough para cord I had left, I went with a simpler design that I had done once before.

So it’s been a while since I last posted about my OLED watch, and I’ve done a lot of work on it! (And also broke it multiple times)
It’s taken me a lot of work to get this far, and I developed EVERYTHING from the ground up. The electronics design, the PCB layout, the RTOS and firmware drivers, the graphics engine, the user-mode app code, and even USB communications apps. I’ve used C, C#, and Python extensively in this project, and Altium Designer for the schematic and PCB.
Overall it has been an awesome learning experience, and if I was to make another one I would do a lot of things differently!

OLED Watch v4.2 @ Walltech. John writes-
I just finished writing up my OLED Watch project on my website! I took loads of great pictures, and explained the whole thought process of the project, as well as the hard ware and software behind it! I’ve officially released the board files and the code under the appropriate creative commons licenses, and just wanted to let you know that it’s all now online on walltech.cc! You guys have been strong supporters of my projects and really thank you for that.

WatchDuino is an open hardware project that combines inexpensive electronic components and a complex Arduino (C++) code to build a useful and reprogrammable smart watch.
The code and the components have been optimized after a lot of prototypes to provide a rich set of features with a small and cheap battery that can last more than a week without recharging. A lot of electronic and software engineering was required to make this project possible.

This watch, by Jonathan Cook, recently won MAKE’s Arduino Challenge, as posted on Bits and Pieces from the Embedded Design World. [via]
The watch is the latest iteration of an ongoing BLE watch endeavor Cook has been exploring for the past nine months. In addition to time and date functionality, he’s building interfacing that any smartwatch wearer would want — email, Facebook notification, Twitter updates, etc., and hopes to have the community further the platform as well.

The Oscilloscope Watch by Gabriel Anzziani of Gabotronics:
The Oscilloscope Watch has all the features of a modern watch (time, calendar, alarm, etc…) combined with all the features of the popular Xprotolab (Oscilloscope, Waveform Generator, Logic Analyzer, Protocol Sniffer, Frequency Counter).
Currently on Kickstarter

Zak Kemble build a digital wristwatch with a 1.3″ 128×64 OLED display & AVR ATmega328P microcontroller:
The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight (each pixel produces its own light), but mostly because they look cool. The watch was originally going to have a 0.96″ display, but this proved too difficult to get all the things I wanted underneath it. Going up a size to 1.3″ was perfect.

You’ll be the talk of the town when you wear this obnoxious, oversized, completely impractical wristwatch. Display your favourite foul language, song lyrics, prime numbers, etc. Inspired by the Microreader kit, I decided to make a giant watch using similar sixteen segment displays. Twelve hours later, I came out of my masochistic fugue and stopped trying to route a sixteen bit data bus on a single sided pcb small enough to wear on your wrist. Returning to my digikey box of mystery, I came up with a four character display made up of 5×7 led matrices. 7 bit parallel data input, no need for umpteen current limiting resistors, upper and lower case characters, the rest writes itself.
