Bell Model 202 Bluetooth Telephone (1930-2018)

Using the magic of Arduino and clash of historical culture I added Bluetooth to an antique Bell model 202 telephone to light up convention conference “Hello my name is” name tags worn by persons at the party. Anachronism in its purest form.

There are two parts to this. On one end I have an ancient phone from the 1930’s. On the other end, I have one of a dozen “name tags” with hidden LEDs. When a person dials the correct number on the phone, a bluetooth connection is made to a name tag pinned to a person’s lapel. When the connection is made, the phone plays a funny message and the name tag flashes in all sorts of crazy colors.
