Thank you that would be great! The board looks good, although I can't make up my mind about the attached VGA port.

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

I don't follow you. What's the problem with the VGA port?Blackbird60 wrote: ↑Fri Apr 21, 2023 9:22 am The board looks good, although I can't make up my mind about the attached VGA port.

It's not a problem, I don't think. It's more of a personal preference.mrtinb wrote: ↑Fri Apr 21, 2023 10:22 amI don't follow you. What's the problem with the VGA port?Blackbird60 wrote: ↑Fri Apr 21, 2023 9:22 am The board looks good, although I can't make up my mind about the attached VGA port.
Is your board intended to be mounted outside of the '81 case or will it fit inside in place of, say, the modulator?
Re: ZX-WESPI - add a cheap wifi-enabled fileserver to your Zeddy!
This has not been a part of my consideration. I plan to have a custom case for my ZX81, with custom keyboard. As I don't think the original keyboard and case are very useful.Blackbird60 wrote: ↑Fri Apr 21, 2023 7:08 pm It's not a problem, I don't think. It's more of a personal preference.

I currently use the non-video version of Wespi, and created this version of the PCB to try the video version of the Wespi.
Re: ZX-WESPI - add a cheap wifi-enabled fileserver to your Zeddy!
Just a minor addition.
I just reconfirmed that WESPI doesnt work with an OS Rom v550
You put in the 649 version and it works.

Martin - I look forward to hearing about how the video works out. I thought about going that route, but since I have an RGBtoHDMI already for my Beeb, I ended up feeding the signal into that.
Its super sharp, but due to the price of an RGBtoHDMI, I wouldn't recommend this approach.
(But if you had a RGBtoHDMI already, or wanted one for other computers that you have...)
Here's some pictures that probably due to image compression, dont do the sharpness justice...

So I finally got to assemble the Wespi pcb I ordered. So why are there so many wires? Because I used the wrong footprint for the ESP32-Wroom board.
I've flashed the firmware, and get a white screen, when no ZX81 is connected.
However when I connect the ZX81 video signal, I get big pixels in black and white, changing rapidly.
Yeah, I must have done something wrong. But the diagnostics will go on another evening.

Re: ZX-WESPI - add a cheap wifi-enabled fileserver to your Zeddy!
Is there any way I can get my grubby hands on two of those PCBs or the files to have them made? They look really great and if left to my own devices it's going to be proto board to build this (and that away looks ugly!) Happy to have them made myself if that is an option.
