ZX-WESPI - add a cheap wifi-enabled fileserver to your Zeddy!

Very nice!

Are you going to add an on/off switch to disable it for tape loading?

[bgrier]

Nicely done!

Thanks! Still working off the rough edges -- literally, the last batch of PCBs were 1mm too long for the case. Filed them down to fit. Now to redesign the case to allow for that.

I love it!!

Thank you! I'm having fun with this design

Thanks! And I thought it automagically allowed for direct tape loading... page one of this thread says '.. It senses when a jack is connected for comms with a real tape recorder/maxduino/tzxduino and will not trigger' or has that since proven to be problematic? I've not tested cassette load yet - don't have the devices necessary (yet).

I did briefly noodle with the idea of adding an additional button to the case to allow a soft reset (short the Z80 reset signal to ground). Would save unplugging-replugging the power connector to reset. Might still, but that's for future. Still working out the design bugs, as it were.

It does support tape loading but I have fitted at least 10 of these and I could not get any of them to load from tape! I can see that they are trying but they never load anything - tape or TZXDuino.

In the end I started fitting a switch on the Ear and ULA lines:

Ah, interesting. I'll have to test for that once I get some sort of tape playback device.

Nice looking wiring! Very neat job.

Sorry if its been mentioned but what about compatibility with a smaller board like a Wemos S2 Mini?

[mikeh_nz]

My belief is no.

If your looking for a smaller board that does work - you can use this one

I don’t think it has all the pins accessible for the LCD version of the WESPI - but it can definitely handle the minimal wespi (hooking up to SVP,IO22,VCC,GND pins) - I’ve done two zx81s with these already

Oooh, that looks interesting. Might have to see if I can create a tiny version of my external PCB to accommodate. Another fun challenge!

I'd like to try one out. Do you have any spare (I can pay for it) or can you supply the files?
Cheers
