太陽能神諭隨身聽 Solar Oracle Walkman

本實驗是在SGMAK Hacker-in-Residency Programme完成的可運作原型。太陽能神諭隨身聽(Solar Oracle Walkman)是一個能源交易與聲音雕塑的探索,由一個I-V測試儀改造而成,能將手工製作的DSSC(solar mini disc)轉成聲音。每一片solar mini disc的TiO₂層經由氰版顯影或網版印刷圖案化製造刻意缺陷,產生獨特的I–V聲紋V,並透過oracle(將鏈外資料安全橋接至區塊鏈的機制)提交至智慧合約進行驗證,鏈上的驗證通過後,即在隨身聽上將V轉為可重現性的生成音樂。本裝置運作如同冷錢包:每片DSSC對應一個可驗證的鏈上身份(panel_id)與其承諾值(commitment),panel_id可作為未來代幣化的錨點。在已完成的v1原型中,量測到的I–V曲線會被分解為七個無量綱特徵[FF, Vmpp/Voc, Impp/Isc, Rs*, Rsh*, Σκ, A*],再做PCA降維,然後手動映射至另一個獨立訓練的nn~ RAVE解碼器的潛在輸入口,以達成可重現的聲音身份,而不依賴明確的語意結構。在下一個實驗v2裡,預計將記錄在不同光照下的連續I–V數據,並訓練I–V編碼器以學習每片電池的緊湊且具抗光照變化性的潛在嵌入。這些嵌入在鏈下進入模糊提取(fuzzy extractor)流程(量化 → 輔助資料錯誤更正(ECC)→ 哈希運算),以導出穩定的金鑰K;鏈上只錨定由K推導的承諾值(commitment)與panel_id,以維護隱私並允許驗證。若能保持向量空間(VSP)的幾何關係,潛在空間中的距離將能反映光伏行為的差異,建立更完整的語意空間。在藝術與哲學的視角下,本「占卜機」裝置連結物理世界與信息世界,是一個結合感知哲學與區塊鏈的視角探索「真實」的提煉與實現化。目前本原型裡的聲音並非單純再現,而是將理論納入編曲設計裡做為導向與反思工具,將技術流程(量測、特徵提取、上鏈驗證)與哲學框架(感知、真實、幻覺)彼此連結。


This experiment was realized as a working prototype during the SGMAK Hacker-in-Residency Programme. The Solar Oracle Walkman is an exploration of energy trading and sound sculpture, adapted from an I–V tester to transform handmade DSSCs (“solar mini discs”) into sound. Each solar mini disc’s TiO₂ layer is patterned by cyanotype or screen printing to deliberately introduce defects, generating a unique I–V voiceprint V. This voiceprint is submitted via an oracle, a mechanism that securely bridges off-chain data to the blockchain, to a smart contract for verification. Once verified on-chain, V is rendered on the Walkman as reproducible generative music. The device functions like a cold wallet: each DSSC corresponds to a verifiable on-chain identity (panel_id) and its commitment value. The panel_id can serve as an anchor for future tokenization. In the completed v1 prototype, the measured I–V curve is decomposed into seven dimensionless features [FF, Vmpp/Voc, Impp/Isc, Rs*, Rsh*, Σκ, A*], reduced with PCA, then manually mapped to the latent inlets of an independently trained nn~ RAVE decoder, producing reproducible sonic identity without explicit semantic structure. In the planned v2 experiment, continuous I–V data under varied illumination will be recorded, and an I–V encoder will be trained to learn compact, illumination-robust latent embeddings for each cell. These embeddings will pass through an off-chain fuzzy extractor pipeline (quantization → error correction with helper data (ECC) → hashing) to derive a stable key K. On-chain, only the commitment and panel_id derived from K are anchored, preserving privacy while enabling verification. If vector-space preservation (VSP) can be maintained, distances in the latent space will reflect differences in photovoltaic behavior, establishing a richer semantic space. From artistic and philosophical perspectives, this “divinatory machine” links the physical and informational worlds, exploring the distillation and realization of “truth” through the lenses of philosophy of perception and blockchain. Currently the sound in this prototyping is not a mere reproduction: theoretical frameworks are integrated into composition as guides and reflective tools, linking technical processes (measurement, feature extraction, on-chain verification) with philosophical frameworks (perception, reality, hallucination).
