Some of you guys may have seen my previous video on the Talking Thermometer prototype, or even the first one where I was beginning the paused project. Also possibly seen are my videos on the EPROM player project.
This is the finished device, the talking thermometer (an AD594 thermocouple transducer chip and a PIC18F4580 microcontroller), which is a module to connected to the EPROM player, which plays audio from an EPROM or EEPROM.
The microcontroller converts the temperature value with its ADC into the five (!) temperature scales, and addresses the EPROM accordingly to say the temperature by concantonating pre-recorded voice samples.
All have heard of Celsius (Centigrade) and Fahrenheit. Most have heard of Kelvin. But few have heard of Rankine and Réaumur.
Rankine is like a Fahrenheit version of Kelvin. 0°R is absolute zero, but Rankine's units are the same size as °F.
Réaumur is similar to Celsius, with 0°Ré being freezing point of water. But boiling is 80° Réaumur.
