Battery holder and the microcontroller board are mounted with double-sided sticky tape. (the one with foam-core). The microcontroller board that's been used is a breadboard version of an arduino-inspired design which I dubbed the 'ottantotto' since it uses the mega88. You can use any microcontroller board you like (A normal Arduino or Arduino nano or mini will do fine). You can also try to build the ottantotto design on breadboard, as described on the ottantotto wiki
