This blog post presents a gamification framework designed for ETHDO.ME: The Regenerate Superhero Hideout, a collaborative makerspace at ETHDenver 2025. The framework leverages a point-based reward system to incentivize and recognize a wide spectrum of participant activities, from hands-on maker missions to community-driven quests and interactive mini-games. Seven categories of points are introduced, each with distinct eligibility criteria and verification protocols. Our approach aims to transparently and equitably distribute a community-sourced prize pool among participating builders, thereby fostering collaboration, creativity, and sustained engagement.
Near-Field Communication (NFC) has rapidly evolved from a niche technology to a cornerstone of modern IoT and interactive designs. From contactless payments to digital ID badges and beyond, NFC is everywhere—and for good reason. In our ETHereal Crystals project and throughout our makerspace, we’ve adopted the PN532 NFC RFID V3 module as our go-to choice for all things NFC.

When it comes to rapidly prototyping interactive devices, few microcontroller modules offer the sheer flexibility and performance of the ESP32-WROOM-32D. We selected this powerhouse microcontroller for two major projects: the ETHereal Crystals and as our primary board for workshops and prototyping.
The concept of gamification for social good has gained momentum as emerging technologies enable new forms of user engagement. ETHDO.ME extends this paradigm by integrating blockchain-based point systems with a clear philanthropic objective. Our aim is to show that game mechanics and user-friendly smart contracts can drive tangible impacts, both educationally and charitably.
I am pleased to share my proposal for implementing and documenting the ETHDO.ME Makerspace NFT Contract for ETHDenver 2025. My plan focuses on using a single smart contract—based on the ERC-1155 token standard.
