Arikado is the personal project portfolio of sau412, a developer whose work spans cryptocurrency, privacy, accessibility, amateur radio, and small creative tools. A central focus is Gridcoin, a cryptocurrency associated with contributing computing power to scientific tasks through BOINC. Arikado’s active Gridcoin-related projects include a mining pool, faucet, Reddit tipping bot, online wallet, Russian-language wiki, privacy resources, and a clicker game inspired by Gridcoin mechanics. The site also features a melody player that interprets old ringtone text and firmware for the ESP32 CYD device, designed in the style of classic PDA software.

Other projects, presented in Russian, include a blog, a fan-fiction text search tool, practical Morse code and Braille exercises with RSS reading and chat, and a QTH locator map for encoding and decoding coordinates. Arikado also documents discontinued cryptocurrency services, including wallets, faucets, mining tools, and conversion utilities. These archived listings are identified as discontinued rather than current offerings. The portfolio provides contact details for questions about the projects.
