This is a basic stay-alive kit that includes a 16V capacitor, a resistor & diode for current in-rush limiting, a 15V Zener diode for voltage limiting, a micro pin & socket set for bypassing the circuit, bits of heat shrink for the connectors and assembly instructions.

The 10mm x 20mm 2200uF cap provides about 0.5-0.75 seconds or so of motor/sound/lighting.
The 13mm x 21mm 3300uF cap provides about 0.75-1 seconds or so of motor/sound/lighting.
The 13mm x 25mm 4700uF cap provides about 1-1.75 seconds or so of motor/sound/lighting.
