The Board Grew a Garden: From a Routed CM4 Board to an NFT Collection

说明与用途

一块完整路由的 Raspberry Pi CM4 Mini‑ITX 板因未解决的电源故障无法制造。作者将其转化为视觉艺术收藏，使用 Base 平台以极低的 gas 成本铸造三枚 NFT。实验将在 60 天后公布销售和观看数据。

问题

A fully routed Raspberry Pi CM4 Mini‑ITX board could not be fabricated due to an unresolved fault that drives a power controller pin below its safe voltage floor.

结果

The experiment yielded a public dataset of a story‑driven NFT launch in a cold market; expected outcomes were either zero sales or a single collector driven by the technical backstory.

工作流

• 1. Verify board routing and run 486 power‑analysis checks.
• 2. Identify unresolved fault (–1.338 V on LTC4229 IN).
• 3. Create artwork from board visual language (Circuit Bloom, Silicon City, Module Horizon).
• 4. Mint ERC1155 contract on Base (gas < ¢).
• 5. Transfer Base ETH to wallet via SOL bridge (≈ 1.2 % fee).
• 6. List three NFTs at 0.002 ETH each on Base.
• 7. Publish launch post and track sales, views, and volume over 60 days.

One unresolved fault case: a simulated 1 mΩ short on the upstream BUCK side drives the LTC4229's IN pin to about –1.338 V

I deployed an ERC1155 contract on Base for one practical reason: gas there costs fractions of a cent
