Robot Eyes

Read full description

Give any robot eyes with the iPhone you already have. Robot Eyes turns an iPhone Pro into a robot's camera and a dataset recorder at the same time, from one camera session, so the live stream and the saved recording share one clock and one frame counter. RECORD • Color video (HEVC), LiDAR depth and confidence maps, accelerometer and gyroscope, and the camera's position and orientation from ARKit, with per-frame camera intrinsics. • The open Stray Scanner dataset layout, readable by existing tools, plus a session.json that summarizes rates, thermal state, battery and completeness. • Crash-safe fragmented video, a clear Complete / Incomplete state for every session, Keep pins, bulk Select ā–ø Delete, and Share with real progress and a Cancel that works. STREAM • Live camera over the USB cable in the Mobcam wire format (the one Moblin uses), 15 fps by default, adapting to heat. • A once-a-second status message: frame rates, thermal, battery, free storage, camera tilt, and optionally the camera's position, heading and speed at 5 to 15 Hz. • A small HTTP file server for the measurement files, so a computer can grade a run seconds after it ends. • Your computer may start and stop recordings, if you allow it. • A ROS 2 camera adapter (Humble and Jazzy) publishes Image and CameraInfo, with checkerboard calibration support. • Wi-Fi is off by default. Turn it on and receivers must present the access token shown in Settings. MADE FOR THE BENCH • Every screen carries a one-word label, so "be on the Record view" is a checkable instruction. • A heads-up display in words, not icons: what the stream is doing, what the disk is doing, what to do next. • Presets for a general recorder and for the Robo Bump Truck, the RC truck this app was built to drive. PRIVACY • No account, no analytics, no ads, no third-party code. Nothing leaves the phone unless you connect a receiver or tap Share. Support: rooneytech.pages.dev/robot-eyes REQUIRES • An iPhone with a LiDAR scanner (iPhone 12 Pro and later Pro models) and iOS 18.6 or newer. Robot Eyes is built on the open-source Stray Scanner recorder (MIT). Source and the ROS adapter: github.com/12mv2/robo-bump-truck-ros

About

42 Editor

Features
Read full description

42 Editor is a code and text editor for iPhone and iPad. It opens the files you already have, in the Files app, iCloud Drive, Working Copy, Dropbox or any other file provider, and saves your changes back to the same file. There is nothing to sign in to and nothing is uploaded. Sometimes the file that needs fixing is a config file, a script or a spreadsheet export, and the only device to hand is a phone. 42 Editor is made for those moments. EDIT IN PLACE • Open a file or a whole folder from any provider in the Files app. Your changes go back to the original. • Opened folders are remembered: create, rename, duplicate and delete files and folders inside them. • Recent files reopen with one tap. • Open in 42 Editor from the Files app and the share sheet. SYNTAX HIGHLIGHTING FOR 29 LANGUAGES Python, Swift, JavaScript, TypeScript, C, C++, Objective-C, C#, Java, Kotlin, Go, Rust, PHP, Ruby, Dart, Lua, R, JSON, YAML, TOML, INI, XML, HTML, CSS, Markdown, Shell, SQL, Makefile and Dockerfile, in light and dark. Line numbers with the current line marked, and long lines that wrap or scroll sideways. A KEYBOARD ROW FOR CODE Tab and outdent, a comment toggle, cursor keys, undo and redo, and the brackets and symbols the iOS keyboard hides. Auto-indent, optional closing of brackets and quotes, and tabs or spaces at 2, 4 or 8 wide. FIND, REPLACE AND FORMAT • Find and Replace, Go to Line, toggle comment, and indent or outdent a selection. • Format or minify JSON, keeping the order of the keys. • Markdown and HTML preview, a tap away. CSV AND TSV AS A TABLE A grid with a pinned header row. Edit cell by cell; add, duplicate or delete rows and columns; sort, filter and undo. The raw text is one tap away. CAREFUL SAVING 42 Editor keeps each file's text encoding (UTF-8, UTF-16 or Windows-1252), its line endings and its final newline. It autosaves two seconds after you stop typing, and if another app changed the file in the meantime it stops and asks which version to keep. iPHONE AND iPAD System, light or dark appearance, font size from 9 to 32 pt, and ⌘S to save on a hardware keyboard. PRIVATE No account, no ads and no analytics. Your files stay on your device and in the providers you choose. 42 Editor is an editor, not a place to run code: it doesn't compile or run anything.
