Hardware and software for the Nordmende Minibox conversion to an internet radio
This is a project to develop and internet radio that can be fitted into an old Nordmende Minibox radio. These radios were produced in the late 50’s to early 60’s and used a 6 transistor superheterodyne circuit. The version I have is from 1959:
A block diagram for the circuit is:
The detailed circuit diagrams (in KiCAD format) are here.
v0.01-breadboard is a breadboard version (i.e. pre-release). Uses VS1053 breakout board. Uses ATMEGA 328 as front panel controller (missing band switch). No SPI connection between front panel controller and main processor (ESP8266).
