Electra Calc
Engineering calculators for PCB, RF & components
What it does
Electra Calc is a fast online toolkit for electronics engineers, PCB designers, and makers. It brings practical engineering calculators together in one place, covering PCB design, RF calculations, resistor and capacitor decoding, and common component math—so you can get quick answers without digging through spreadsheets or scattered tools.

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…
