DATASHEET.AI — Embedded Systems Assistant Stop wasting time hunting through hundred-page datasheets. DATASHEET.AI lets you upload any component datasheet and ask questions in plain English — getting precise, technical answers in seconds. What it does: Upload a PDF or search by part number (STM32, ESP32, MPU-6050, and more), then ask anything: voltage ranges, register maps, SPI/I2C configuration, pin assignments, operating temperature limits, or power consumption. It reads the datasheet and answers like a senior hardware engineer sitting next to you. Need to write driver code? Ask for a firmware snippet and get clean, commented C code using the exact register addresses and initialization sequences from your component's datasheet — ready to drop into your project. Key features: Instant answers from any PDF datasheet Search by part number — finds and loads the datasheet automatically Generates firmware and driver code snippets from datasheet specs Handles large datasheets by sourcing them directly from manufacturer sites Runs entirely in your browser — your API key never leaves your machine Built for engineers who'd rather be building.

Audio to Text transcriber that is searchable and timestamps text for logging. Transcriptions can also be exported for full documentation conservation.

UART Decoder is a browser-based tool that lets engineers paste a raw serial hex stream (or upload a logic-analyzer CSV), automatically split it into frames, and decode fields like header/command/value using customizable protocol templates. It highlights ASCII vs binary content and verifies common checksums (XOR, SUM8, CRC-8, CRC-16 Modbus), showing per-frame validity plus clean tables and summaries for fast debugging.

PCB Trace Width Calculator is a fast, browser-based tool that estimates the required PCB trace width from current, copper weight, layer type (internal/external), and allowable temperature rise using IPC-2221 equations. It also includes optional trace-length inputs to estimate resistance, voltage drop, and power loss, giving engineers a quick, practical sanity check for high-current routing decisions.

Closure Log Search is a browser-based log file utility that lets you search through large .txt log files without any server or installation required. You load a log file, type a search term, and it returns only the lines where that term appears and the line ends with filtered! somewhere after it — filtering out noise like raw data references that contain the same string but aren't flagged entries. Results show line numbers with the match highlighted, and you can either copy them to clipboard or download them as a .txt file named after your search term.

TONE DETECTOR — App Summary Tone Detector is a browser-based audio analysis tool designed to detect and timestamp three specific low-frequency tones within an audio file. It requires no installation or internet connection — everything runs locally in the browser. What it does The app scans an audio file for three tone types: LOCAL (25 Hz) — detects when a 25 Hz tone is present alone ID (35 Hz) — detects when a 35 Hz tone is present alone EOB (25+35 Hz) — detects when both tones are present simultaneously For each detected event, it reports the absolute timestamp (offset from a user-defined start time) and the duration of the tone in milliseconds. How to use it Drop or browse to an audio file (WAV, MP3, FLAC, OGG, M4A supported) Set a start time in HH:MM:SS format — all reported timestamps will be relative to this clock offset, making it easy to correlate detections with a real-world recording timeline Adjust analysis parameters if needed, then click Initialize Analysis Configurable parameters Window Size — the size of each analysis chunk in milliseconds; larger windows improve frequency precision at the cost of time resolution Hop Size — how frequently windows are sampled; smaller values give finer time resolution Detection Threshold — the minimum signal level (in dB) a tone must reach to register as a detection Frequency Tolerance — how many Hz either side of 25 and 35 Hz the detector will accept, accommodating slight pitch drift in real recordings Output Results are displayed in three color-coded columns (green/LOCAL, blue/ID, amber/EOB), each listing every detected event w
