To cut a long story short, it was agreed by the occupants of the house that something singular must be done about extending the range of the front door bell/chime. Drawing parallel connection to the existing line would be tedious and involve running cables in a concealed manner.
So the resident techie was expected to come up with a quick and dirty solution to this problem. A quick check on the Net revealed that there was no direct solution available south of 40 dollars. Eventually I ended up making a simple circuit which extended the front door bell range right to the first floor - all at the cost of less than 5 dollars with about one hour of time well spent.
Before we go further let us take a look at the parts and complexity involved in this simple little project.
1. 6 V Relay DPDT contacts rated at 5 A @ 240 V X 1 ( contacts can be 1 A and I used what was readily available)
2. 6 V or 9 V power supply Adapter with 500 mA output X 1
3. 1000 μF/16V Electrolytic Capacitor X 1
4. Cordless Calling Bell X 1 ( Preferably with telescopic antenna at both the handset and the Ringer base unit)
5. Short length of hookup wire
Skill set: A bit of Soldering is required
