Flicker Meter for Light vs Pixel Mapper xModel

Suffering from eye strain, headaches, or migraines from LED lights and screens? You're not alone. Many LED lights, screens, and fluorescent lights flicker at high frequencies invisible to the naked eye, yet capable of causing headaches, eye strain, fatigue, and other symptoms. This app helps you identify which light sources and screens are flickering, measure the intensity, and find flicker-free alternatives for your health and comfort. FEATURED IN COMPUTER ACTIVE MAGAZINE Computer Active recommends this app for detecting headache-inducing flicker. KEY FEATURES • Detect invisible high-frequency flickering in LED lamps, screens, and fluorescent lights • Measure flicker intensity in percentage • Measure flicker frequency in Hz • Identify flicker-free light sources • Easy-to-use interface with instant results HEALTH BENEFITS • Reduce eye strain and fatigue • Minimize headaches and migraines • Create a more comfortable work environment • Make informed decisions about lighting purchases PERFECT FOR • Office workers spending long hours under artificial lighting • People sensitive to light flicker • Anyone experiencing unexplained headaches or eye strain • Professionals evaluating workplace lighting • Bird owners monitoring aviary lighting (birds are highly sensitive to flicker) Full support for 40 languages with integrated documentation.

Pixel Mapper turns your iPhone or iPad into an automatic layout tool for xLights. Point your camera at your light display, and the app lights each WS2811 / WS2812 pixel, finds it in the camera image with computer vision, and builds a ready-to-import xLights Custom model — no manual clicking pixel by pixel. Perfect for Christmas light displays, props, matrices, megatrees, and any irregular pixel layout that's painful to map by hand. HOW IT WORKS 1. Target — enter your controller's IP and pixel count. Output goes over DDP or sACN / E1.31, the same protocols xLights and FPP already speak. 2. Scan — choose a mode: • Fast (base-3): every pixel lights in every frame, colored by one base-3 digit of its index, so all pixels are identified in only ~log3(N)+2 frames (about 500 pixels in 8 frames). Two checksum digits reject misreads. • Sequential: light one pixel at a time and find the single bright blob. Slower, but dead simple and rock solid. Both modes subtract a black reference frame to ignore ambient hotspots. 3. Review — see the detected layout over your photo, drop bad points, tap to place or move a node, and re-scan individual pixels. Zoom and pan to fine-tune. 4. Export — save a standard xLights .xmodel file that imports into both old and new versions of xLights. WHY PIXEL MAPPER • No more mapping hundreds of pixels by hand. • Works with the gear you already own — any DDP or sACN/E1.31 pixel controller. • Fast base-3 scan maps large models in seconds of capture. • Checksum-protected so misread pixels get rejected, not placed wrong. • Best results in a dim room; the app locks camera exposure and focus where the device supports it. REQUIREMENTS • A WS2811 / WS2812 (or compatible) pixel controller reachable on your network. • The controller set to receive DDP or sACN / E1.31. • An iPhone or iPad on the same Wi-Fi network as the controller.
