This is a website for my personal projects, passion projects I work on in my spare time to keep my skills current, for fun or any other reasons.

Current projects include:

• Pump! Adding Bitcoin Cash (BCH) support to Nostr. Nostr "zaps" using BCH, currently named "pumps".
• racketrumble. A system for running leagues & ladders in racket sports like squash, tennis etc.
• MKWallet. An experimental BCH wallet written as an installable PWA for mobiles, or running on web browsers (and Tesla!).

You can find me on X/Twitter, as marius@coinmachin.es on Nostr (not an email address) or on Linkedin.
