I doubt I'll order one for a while as this one is already working. But I can help debug if you get one.

They're to the layout. I had some extra parts on there to monitor the shot buttons, but I decided not to use them. There were also some routing errors and I found out that I needed a cap on the one side of the isolator, before that I was getting some erratic readings. I do have a new board done that...

I used PC817 isolators: https://www.farnell.com/datasheets/73758.pdf

The oshpark ones needed a few mods to work correctly. The schematic should be updated with the latest version.

Here is the I/O board I made for my Pi that let's me see the state of the boiler on power leds and remotely hit the boiler and power buttons s1.png I currently have it set up so that I can access and control the current machine state over an http api. It alsostores a summary of each power on cycle i...

You've probably replaced this already, but for anyone else that may run into this, I had the same issue. What fixed it for me was getting the boiler up to pressure and then manually lifting the valve up. This caused a bunch of steam to escape and, I'm assuming, cleaned out anything that was stopping...

I now have it rigged together to just power the machine on at fixed times, but I'm going to get some boards spun and ...

Thanks!

I just bought a new (to me) Vivaldi ii S1 and it doesn't have the braided line that I see most other people have. Does anyone know what the size of the connector directly on the machine is?

I just tried to download the image, but was given a not found error message

Thanks! Do you have the source code on GitHub or some other other version control service? I'd love to poke around at it without downloading and extracting the full image.

I've just started looking into buying an s1 mini. After seeing the official timer, I started looking around trying to find documentation on how it works and I ran across your project. This looks really awesome! Any chance you would make just the source code available? I'd love to see how things actu...
