It's a super cool project but this post is not close to being a valid Show HN. Please read the rules: https://news.ycombinator.com/showhn.html. (The submitted title was "Show HN: The World's Cheapest Supercomputer", which also broke the HN guidelines by being baity.)

Not only that but you had a huge Show HN just 3 months ago: https://news.ycombinator.com/item?id=36933603, making this repost a dupe by HN's rules (https://news.ycombinator.com/newsfaq.html) - and not only that but the earlier post, being a signup list, wasn't a valid Show HN either. Evidently we missed that.
