I should have mentioned that the project is 11 years old (2012) so things were a but different (rpi were just out, no Chinese padauk-like 5cts microcontrollers but also attinys were less expensive pre covid !) And yes it uses a 512k flash :)
- nickcw 3y agoAh that makes sense! I think I'd use a rasperry pi pico now-a-days for about the same cost but with enough flash built in (2MB) and enough processor to play mp3 files. See this example project which makes a pi pico into an mp3 player from a PWM pin. https://embeddedcomputing.com/technology/processing/interface-io/simple-mp3-audio-playback-with-raspberry-pi-pico https://embeddedcomputing.com/technology/processing/interfac...
- makapuf 3y agoI'm a cheapo, I'd use a ch32v003 an stm8 or a modern attiny ;) or maybe a stm32 with 128k of flash and a dac and would compress the audio.. much more choices now ! Speech synthesis on a cheap mcu would be awesome
