Completely open source watch with tons of features

There are lots of DIY watch projects on the internet. Some of them are great, some of them lack to feel of finished product. If you looking something like this check out at F*watch project which open source and built by using free tools. It was developed at CERN as a gift for retiring colleague. It has everything you would expect on modern digital watch. It has been stuffed with bunch of sensors including GPS, Pressure sensor, accelerometer, compass, ambient light sensor. Watch has 128×128 LCD display with back-light, micro USB connector, four push buttons buzzer, vibrating motor, and microSD memory card. It is powered by 500mAh Lithium-ion battery. To make it all possible, schematic was designed on four layer PCB with KiCad. Case was 3D printed out of resin. Plans were developed with open FreeCAD design tools. Clock is ticking around ARM Coretex-M3 microcontroller from SiLabs Giant Gecko featuring 128KB RAM and 1MB of Flash. Watch software runs a FreeRTOS operating system. Watch is fully functioning already, but seems that team are open for bug reports and feature request. Continue reading

Watch With Oscilloscope

This is a must have watch for geeks. It combined all the features of a watch along with an oscilloscope and surprisingly a waveform generator. I would say it’s the nerdiest thing you can put on your wrist. Another good thing about the watch, that it’s hack able. With access to hardware design, users can write their own applications. The brain of the device is a powerful 8-bit XMEGA microcontroller, easy to program in C or assembly. The estimated battery life will be over 30 days on each charge without using the oscilloscope. When using the oscilloscope, the battery will last about 12 hours.  The Oscilloscope Watch uses a 1.28″ e-paper display which combines fast refresh rate and great contrast, with a very low power consumption. It has features of oscilloscope, multimeter, freqency counter, logic analyzer, and a waveform generator. The project is being worked upon to make the enclosure water/ splash proof so as when it’s raining outside, the watch didn’t get destroyed. The enclosure are made out of plastic and are splash proof. I have to say, what… Continue reading

Open source low power wristwatch with 3D printed case

open source watch with 3d printed case

Wrist watch first of all is an accessory which is always with you. So you may want it to be unique, convenient, useful and of course hackable/programmable. While big players like Apple, Google and Samsung are working on smart watches, Hairy Kiwi has built a great open source watch prototype called OTM-02. He wanted to use energy efficient technology in it, so practically once he coupl put hands on few on them, he started working on this watch. As heart he’s chosen Energy Micro ultra low power Leopard EFM32 ARM microcontroller. Since every watt counts, he used long waited 128×128 memory LCD from Sharp Microelectronics. It consumes about 60uW on static image display. Watch is powered from 150mAh Li-Po battery. Watch can be programmed and charged through USB port. It also features a vibrator motor, piezo electric diaphragm for sounds, five miniature tact switch buttons, LED back light. Watch circuit is placed inside 3D printed case – it really looks and feels open source. Like many open source projects it is still experimental and who knows it may include other… Continue reading
