I share to you a very simple ZX81 plug-and-play cheap tape loader project I have built recently.
is very simple to build, no fancy options (no power supply, no buttons, no screen, no WiFi, no folder management),
just the bare minimum to load your wav files into the ZX81 EAR input.
How to use :
- convert your .p into .wav (I use "otla" https://code.google.com/archive/p/otla/)
- put the wav file to a SD card (I use a small capacity 128Mb), and insert into the sdcard input of this project
- launch LOAD "" from the ZX81
- plug the project to the EAR input, press NEW LINE, connect the usb cable to the project
And voila, the program is now loading.
Note the Wav will be played continuously, useful if you need to reload program.
Here are the schematic and .ino file.
