Developer Launches Browser-Based 3D Circuit Simulator Powered by Three.js and AI

·1 views

A developer has built and released a browser-based 3D circuit simulator called LuvaAI, accessible at luvaai.in with no installation or sign-up required. Users can place components on a virtual breadboard in 3D, wire them together, and run basic simulations directly in a browser tab. The tool is built using React 19, TypeScript, Vite, and Three.js, with an AI assistant panel powered by Google's Gemini 2.5 Pro to help check circuit states. User designs can be saved via Firebase and Firestore after signing in with a Google account. The project currently lacks full transient and AC frequency-domain analysis found in professional tools like LTspice, and mobile touch controls remain a work in progress.

Codex benchmark tests when multi-agent AI engineering actually beats solo work

A new dependency-free benchmark published in Codex How To evaluates whether splitting a software task across multiple AI agents genuinely outperforms a single-agent approach. The test uses an incident-response application with two clearly separated code surfaces — backend persistence and a browser client — assigned to distinct agents under a controller. In an initial smoke run, both single-agent and orchestrated setups passed all supplied tests and external evaluator checks, though the multi-agent run additionally produced live browser interaction evidence. The benchmark concludes that parallel agents are only justified when tasks have frozen interfaces, exclusive write paths, and coordination costs that are measurably outweighed by gains. The framework is designed to be rerun repeatedly so teams can build evidence before committing to an orchestrated workflow.

Developer Launches Curated Directory to Help Users Find n8n Community Nodes

A developer named Bhav Shekhaliya has created 'Awesome n8n Community Nodes', an open-source curated directory hosted on GitHub to simplify the discovery of community-built integrations for the n8n workflow automation platform. The project addresses a growing discoverability problem, as thousands of community nodes already exist on npm but are difficult to find without knowing exactly what to search for. The directory organizes nodes into practical categories such as AI and LLMs, browser automation, communication tools, databases, and CRM integrations. Each entry links to its corresponding npm package and, where available, its public source repository. The maintainer cautions that the directory is not a security endorsement, and users should review source code, dependencies, and licenses before installing any community node.

Hacker News Community Asked to Identify Persistent Weaknesses in LLMs

A Hacker News user has posted an open question asking the community to share simple tasks that large language models like ChatGPT and Claude consistently fail at. The poster states they are seeking ideas to help train a specialized AI model targeting these gaps. The thread invites users to describe recurring frustrations from their own interactions with popular AI tools. The discussion has drawn early engagement on the platform, accumulating points and comments since being posted.

US BankChain Alliance and Zerohash Push Blockchain Into Mainstream Finance

The digital asset market is undergoing a major shift as blockchain technology moves from a disruptive force to an integrated part of mainstream finance. Backed by 39 state banking associations, the BankChain Alliance was announced with a 2027 launch target to develop stablecoins, payments, and tokenized deposits within regulated banking frameworks. Simultaneously, crypto infrastructure firm Zerohash is pursuing a national trust bank charter from the OCC, reflecting the crypto industry's push for regulatory legitimacy. These developments highlight a dual trend: traditional financial institutions adopting blockchain to improve efficiency, while crypto firms seek compliance within established legal frameworks. Together, they signal the emergence of a hybrid financial architecture built on distributed ledger technology.
