8 may 2024 Started with a Datasette with an Arduino and Sd-Card inside
Found a fritzing Diagram of a "casduino" for a C64/PET Datasette. Started with converting the diagram to a KiCad schematic, using the TZXDuino Pico as example, so that I don't need to use a separate SD-card interface board, or 3V3 regulator. this DATASETTE-Duino uses a 2x16 LCD with an I2C backpack..
Conversion to a KiCad schematic
I converted the fritzing diagram to a schematic, using the fritzing diagram and my earlier tzxduino. you can find a .PDF of the schematic here: File:DATASETTE-DUINO.pdf
this is a picture of the schematic:
note the arduino nano pins 19 to 23 that are labelled down/next up stop and play will go to buttons or contacts corresponding to fast.forward rewind stop and play. I plan to modify the datasette so that pressing these keys will ground the corresponding pin.
Stripping the contents of the datasette
I stripped the datasette, afterwards the innards looked like this: 
and this is what was removed from the datasette: 
measuring the dimensions of the cassette compartment
Using a calliper I measured how much room there is for the electronics in the cassette compartment. it is 117mm wide, 68mm high and 14mm deep. the display is 19mm high, so it wont fit below the datasette cover, the cover is 3mm thick. so I need to create a hole in the cover, and perhaps some plastic below the display.
The dimensions of the high metal part of the LCD
is 71mm wide and 24mm high, so I need to create an opening in the cover with these dimensions.
