Dock for Vivoactive

thingiverse

To charge the Vivoactive using any USB power source, you'll need to print the adapter. Cut a USB cable - you only need the red and black wires for this project, as the green and white wires are used for data transmission. Every standard USB cable will have these colors specified. Drill two holes on the left side of the charging dock when viewed from the top. To find the precise location, place the watch on the dock and copy the position of the contact plates as shown in the photo. The upper wire is negative (black), while the lower wire is positive (red). You have two options for creating a reliable electrical connection: you can solder the ends of the wires so that they stick out at the top, which will cost you nothing but may not provide a very reliable contact. Alternatively, you can purchase spring-loaded contacts - I recommend these products: https://www.amazon.com/dp/B007Q847I0?th=1 These spring-loaded contacts ensure perfect electrical contact and are ideal for this project. However, they only come in packs of 10 or more. Glue a magnet to the underside of the charging dock so that it keeps the watch securely attached. Don't forget to set your Vivoactive to settings/system/USB mode: "mass storage" (not "Garmin") before attempting to charge it. This will allow charging to start immediately when a 5V power source is applied. The photo shows a humorous warning - "watch out" - but this message only appears when the watch is removed from its docking position.
