sleepy-btn - super small wireless iot button

Why:

  • needed a battery powered button for general purposes =)
  • extending FreeCad skills using the amazing linkstage3-branch
  • just build a cool thingy with our stick as a base to show what its capable of! ;)

Requirements:

  • be as small as possible
  • have a long battery life (multiple years)

In this video we are switching a light with this button in combination with our CC2652RB flush mounted relay

The housing consists of 3 parts. The bottom, top and the pushbutton-plate.

The inner part is there to hold the actual button in place and at the right height. The holes/cuts are just to print faster :)

To waste as little space as possible we soldered the wires directly to the battery. A battery holder would be too big. Currently we are trying to design a 3D part which will hold the battery and clamp the wires to it!

All of the 3D files will be released soon on our github, the software too.
