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.

Named ‘El Relojito’ (relojo = watch in spanish), this seemingly simple design is a great project for anyone ready to move past the rank of ‘amateur’. 60 LEDs surround the 7-segment leds telling you the time. A PIC micro controls all the action. The write-up is in spanish, but the schematic/pictures should be enough to guide you. [via]

This watch is built around a 3V-powered ATmega328P running at 8MHz. Time is shown using 2 circles of 12 LEDs, in a manner similar to an analog watch (with hands). Minutes are indicated on the exterior circle of green LEDs; hours are indicated on the interior circle of red LEDs, as shown in this video.

The uWatch is an open source RPN and Algebraic scientific calculator watch that you can build yourself. Jones writes: [via]

It only had an 18 key keypad, but I figured that was OK as my old CFX-400 only had 16 + 4 side keys. All the extra functions were performed with a MENU key and two rows of 4 soft function buttons that mapped to the 8 keys directly below the LCD.

Two lights-emitting diode 5*8 matrixes where used to construct a computer controlled spectrum analyzer and clock. Microcontroller ATMEL AT90S2313 is the heart of device. The controllers accepts data from a serial port and with the help of conclusions of port B and the additional decoder 74145 is deduce a spectrum on the light-emitting diode screen are collected from two matrixes.
