This project was made of a board in a typical small housing with polished panel and neat button.
The panel has to be polished twice, as while drilling holes the previous polish can be damaged. It was done using sandpaper 320, then 1000 and 2000 at the end.
In order to fit the small housing KM22 (84x60x22), you have to adapt some of the elements, e.g. sand the plug-ins, lower the position of the board etc. There is no need to place the battery.
Scheme is easily available on the Internet. It was slightly modified in order to fit the small housing.
Below there are some photos:
