Pineapple ONE

As I have hinted in the previous log, we are working on a new version of Pineapple ONE (or how it will be named in the future due to legal reasons). I have made this project open-source so you can find all the files on my GitHub repository (link below). 

And yes, I said "we", because some of you have already reached out to me and offered help, which is amazing! So now we have a Discord server where we are sharing future design ideas and other things. It is a public server so feel free to join, we will be happy to see you there!

We have big plans for the future and we sure have many features that we want to add there, like the already mentioned audio card. We have also created a basic webpage, where you can find all additional information. We still hope to turn this into a DIY kit!

I also talked about it on RISC-V Days Tokyo 2021:

To find the reason why my CPU makes these mistakes, we made a Python emulator of my CPU and we will be connecting it to my hardware in upcoming days. More about it on our Discord, but I will leave you with an image of an early version of that simulation that is currently computing a set of circles:

Here are all the schematics for my CPU - just please keep in mind that Im not (yet) an engineer and there are many things that could be done better, for example the shifter. I would love to turn this into an open-source project and maybe design a do-it-yourself "kit", so everybody could make their own 32-bit RISC-V CPU at home.

For this to happen, some things would need to be redesigned, so the CPU could be "useful" and run much more complex programs, or be even faster.

This is where I need your help. These improvements are too much for one person to do alone and I'm doing these things in my free time only (because of school), so if you think you could help in any way, please, write a comment, contact me on my twitter (https://twitter.com/ten_filip), or drop me an email (filip.szkandera@gmail.com). 

Thank you.

I could't get PDFs here, so JPGs must do for now, sorry!

Those aren't all of my PCBs as I cannot upload more images into one project log it seems. For complete schematics I've added PDF files that you can download.
