Antique Lamp Turned Interactive Installation Using ESP32 and Eight ToF Sensors

·1 views

A maker transformed a brass floor lamp inherited from their great-grandmother into an interactive installation called Bloom Chandelier. Eight VL53L1X time-of-flight sensors arranged in a ring give the lamp a 360-degree proximity awareness of about four feet, allowing it to respond to how close a person is rather than just detecting movement. An ESP32 Feather microcontroller manages all sensors via a PCA9548A I2C multiplexer, cycling through each sensor in sequence to avoid address conflicts on the shared bus. Distance readings control a 59-pixel LED strip divided into eight zones, with brightness scaling on a squared curve, while a connected Raspberry Pi 4 maps proximity data to musical notes derived from wine-glass rim recordings. The project is fully documented on Hackster, and the creator suggests beginners can replicate the core concepts with just a single sensor and one LED.

ValuePair App Matches Friends by Values, Not Profiles, Gains 150 Beta Users

A developer has launched ValuePair, a friendship app that matches users based on meaningful questions rather than browsing profile lists. After completing an onboarding questionnaire, users are algorithmically paired and must work through a 14-question set together before either party can open a chat. Both users must mutually agree to connect before messaging is unlocked, aiming to eliminate shallow interactions and small talk. The questions were designed drawing on peer-reviewed social psychology research, including studies by Aron, Hall, and Finkel. The app has been live for roughly two weeks and has already attracted around 150 users during its open beta phase.

Developer Launches Tooltify360, a Free All-in-One Toolkit Requiring No Sign-Up

A developer has built and released Tooltify360, a free web-based platform that consolidates commonly used developer utilities into a single location. The project was motivated by the inconvenience of switching between multiple websites for routine tasks such as formatting JSON, decoding JWTs, and converting cURL commands. The platform currently offers over a dozen tools, including a UUID generator, regex tester, Base64 encoder/decoder, and a CSV-to-JSON converter. Tooltify360 requires no account creation and is accessible at tooltify360.com. The creator describes it as an ongoing side project and is actively seeking user feedback to guide future improvements.

Developer Builds Two-Stage AI Content Moderation Classifier Using Python and Telnyx

A developer has published an open-source Python Flask application that performs AI-powered content moderation using a two-stage pipeline. The system first uses embedding-based similarity to quickly filter content against a known-bad blocklist, and only escalates to a large language model when no strong blocklist match is found. Built on Telnyx AI Inference, the app uses the Kimi-K2 model for judgment calls and the gte-large model for embeddings. It supports single and batch moderation of up to 20 items, returning structured outputs such as category, confidence score, and a recommended action like allow, flag, or remove. The author notes that a production-ready version would require additions such as persistent storage, audit logging, human review queues, and a feedback loop for tuning thresholds over time.

Guitarist Uses Modular Arithmetic to Simplify Fretboard Memorization

A blog post published on ohaodha.ie explores how modular arithmetic can be applied to help guitarists memorize the fretboard. The author presents a mathematical approach to understanding note patterns across guitar strings and frets. By using the concept of modular arithmetic, repeating note cycles on the fretboard can be identified and learned more systematically. The method aims to reduce the rote memorization typically required by giving players a logical framework for navigating the instrument.
