developed an amazingly versatile BASIC interpreter for the Pi Pico:

Or even cheaper, and Arduino uno
I second the Arduino recommendation. I have a Power Mac G4 with a serial
dongle
that drives an Arduino Nano-based IR blaster. It sends serial commands to
it
and the blaster transmits a signal to the room air conditioner. Should be
easy
to adapt the GPIO pins to a relay. Arduino programming and interfacing is
pretty straightforward.
