A case for the Redox Wireless keyboard with 18650 capabilities

This is a custom made version of the Redox Wireless Keyboard, by mattdibi

With the use of few easy-to-find external components, it will possibile to hook up 2x 18650 batteries and recharge them by simply plugging in a usb cable.

BOQ (per section)

How does it work:

The 18650 battery, which has a nominal voltage of 3.7v, therefore can even reach 4.2v when fully charged, needs to be regulated and limited down by the LM2596 to 3.5-3.6v to not fry the board. The TP4056 allows to recharge the 18650 via a USB cable, not hindering the normal functioning of the keyboard.

Extras:

I've decided to also implements slots for 6x3 to allow further expansions of the case without necessarily print it afresh. I've included a version of some tenting that can accomodate magnets.

Credits:

  • Mattia Dal Ben for the design of this awesome keyboard
  • OlRenso for the design of the 18650 minimal holder, which I've customised to fit in this project
  • RappaportDesign for the tenting kit, which I've remixed to accomodate a magnet!
