DIY Electrolysis Machine

Description: This project explores the design and construction of a DIY electrolysis machine using constant-current control circuitry. The system automatically maintains precise current levels (typically 0.7 mA) for safe galvanic electrolysis applications, eliminating the need for manual voltage adjustments during treatment. Research Background: Based on community research and feedback, the optimal approach involves using a constant-current circuit that automatically adjusts voltage to maintain the target amperage. This ensures consistent treatment while preventing overcurrent conditions that could cause skin damage. ...

Teleology After 5+ years of using Amazon’s Alexa and Google’s Assistant, I was left unsatisfied. Alexa is annoying at best. Google is constantly removing features from their Assistant. Enter Home Assistant - with its built-in Assist platform, I set out to create a custom, local voice assistant. It is worth noting that HASS announced this year that they are working on their own local/cloud-integrated LLM system. I decided to do this project long before that was announced. ...

Home Assistant

overview Home Assistant is essentially a home automation platform designed to be both accessible to users and powerful for enthusiasts. It is hosted on local hardware using software created by Nabu Casa (who also maintain ESPHome, a project I fully intend to utilize in the future). Home Assistant boasts a dedicated enterprise community that have developed a robust ecosystem of hardware and software compatible with Home Assistant right out of the box. Furthermore, through the Home Assistant Community Store (colloquially HACS), users can install and run custom integrations, add-ons, and UI components created and maintained by Home Assistant’s passionate user community. ...

Cultivating Knowledge Through Digital Gardens

If a note is not published, does it really exist? - Erwin Schrödinger* spores The phrase “digital garden” is more of an analogy than a descriptive literal. Just as a mushroom garden flourishes from tiny spores into a complex network, a digital garden nurtures small ideas into a rich, interconnected ecosystem of knowledge. Digital gardens are living entities, constantly evolving as they harbor works in progress, nascent ideas, and fleeting thoughts that, over time, grow and intertwine into a robust network of knowledge. Each note in a digital garden starts small. Over time, as the user researches, learns, and grows, they can apply that learning to the note. Through cycles of addition and refinement, these small notes grow into a network of interwoven thoughts and ideas, providing structure and meaning to an otherwise scattered and messy collection of ideas. ...
