14 DAY TRIAL // Activity trackers are not exactly a dime a dozen, but they are more or less ubiquitous. Not as much as smartphones, but easy to find on sale in various shops and online stores.
If you want to make one on your own, though, you're out of luck. Or you were, until today.
An activity tracker has been published on Instructables, the website that shows every visitor how to go about creating this or that device in the safety of their home.
Called RetroBand, the device is made of an Arduino platform housed inside a 3D printed case.
You'll have to combine the PCBs and bluetooth transceiver with liberal use of electronics tools. Also, you'll have to ask a 3D printing service to make the case for you if you don't own a 3D printer yourself.
Still, once you've done everything to the letter, you should have a new bracelet ready to sync with your Android smartphone (via Bluetooth). An app is used to see the readings.
If you have any experience with CAD designs, you should have an easy time of making the 3D printed band look a bit less clunky. In the end, the electronic hardware assembly is the most important part.
