This DIY Smartwatch Won an Arduino Challenge #WearableWednesday

DIYWatch This smartwatch just smacks of DIY with its exposed screws. What better way to replace a battery, too. This beauty, by Jonathan Cook, recently won MAKE’s Arduino Challenge, as posted on Bits and Pieces from the Embedded Design World. With its Bluetooth Low Energy (BLE), OLED display and hacked Arduino, it’s a little tricky to build, but well worth the open-source bragging rights. Mike Senese on MAKE writes:

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.

DIYWatchOpen Check out all the little blue wires! Cook describes them as “fun” on the project’s site, but also mentions that “patience and solid soldering experience are required”. If you read his directions, you will find that these are actually micro wire and can break easily, so after soldering, they are super glued in place. These wires are all leading to some pretty fancy stuff — a Microduino Core +, a Bluegiga BLE112 chip, and a voltage regulator. Cook has definitely made some well thought out decisions, and what’s not to love about a 3D printed case. It really gives the watch its rugged look.

You are probably drooling thinking about doing a project like this. If you feel like you are ready to tackle this one, go for it. If not, we’ve got something a little more scaled down for you — our Times Square Watch Kit. Make your wrist glow from afar.
