Next, I modified this external bell (hereinafter referred to as Development Unit No. 1) to turn on / off the power of other electric appliances in conjunction with turning on / off the phone.

The purposes of this modification were as follows.

(1) When a call comes in, Development Unit No. 1 turns on the power of another electrical product,

(2) When making a phone call, the development unit No. 1 also turns on the power of another electric product in the same way.

(3) While the telephone line is in use, during the telephone call, Development Unit No. 1 keeps another electrical product powered on.

(4) When the telephone line is no longer used, Development Unit No. 1 turns off the power of another electric appliance.

Then next, I connected a miniature bulb to Development Unit No. 1 and confirmed many times that the telephone on / off and the blinking of the miniature bulb were linked.

Then, it was around 6 am that I connected an actual fax machine instead of a miniature bulb and finally finished the telephone / power supply interlocking experiment by fax. After entering the office, a series of observation of the external telephone bell, movement check of the electrical parts, experiments using a miniature bulb and a fax machine was completed in about 2 hours.

The basics of development were completed in only about two hours. Moreover, Development Unit No. 1 was a diversion of the external telephone bell that was given free of charge.

When I noticed, it was time for the people to go to work early in the morning on National Road 184 in front of the office.
