I've never posted on ShowHN before, but I wanted to share my Xmas 2025 project; to try a new approach to controlling our kids screen time. This also involved massively over-engineering a solution in order to play with a shiny new gadget (and avoid the in laws at Christmas, obviously) I've shared some learnings on AI coding with embedded devices, and how I approached the product design/hardware selection side of things. The Web App is at https://screenie.org - and I'm Open Sourcing the device and web app code later today (links to follow on that site)

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
