I’m happy to share with you a device I’ve been working on for the past few months, SterlingKey™. It can can turn your keyboard into bluetooth! It can be attached to keyboards with detachable cables, both Micro USB and Type C versions will be made, as well as non-detachable keyboards using a small adapter, as seen in the photos.
It can be connected to 3 devices (Windows, Mac, iOS, Android) and using a keyboard shortcut I can seamlessly switch between them. The battery lasts around 15 hours of continuous use in this prototype version.
Multimedia keys are supported! Volume up/down, play/pause etc., as well as any other multimedia buttons your keyboard may have, for example Browser, Home etc.
Keyboard/Mouse combos are also fully supported, as seen in the photos. It can also convert 2.4GHz devices into Bluetooth.
Feel free to ask my anything in the comments, or let me know if you have any suggestions, and I’ll be happy to answer any question you may have!
If you would like to follow my development, check the below links, thank you!
