    Pocket-sized Test Pattern Generator Helps Check those CRTs[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking out old televisions or CRTs, firing up a test pattern can be a pretty handy way to see if the hardware is healthy or not.The little white add-on you see attached to the yellow portion is a simple circuit (two resistors and an RCA jack) that allows the microcontroller to output a composite video signal. All one needs to do is power on the device, then press the large button to cycle through test patterns. A small switch on the side toggles between NTSC and PAL video formats. It’s adorable, and makes good use of the enclosures that came with the dev board and proto board.In a pinch a hacker could use an original Raspberry Pi, because the original Pi notably included a composite video output. That feature made it trivial to output NTSC or PAL video to a compatible display. But [Nicholas]’s device has a number of significant advantages: it’s small, it’s fast, it has its own battery and integrated charger, and the little color screen mirroring the chosen test pattern is a great confirmation feature.This is a slick little device, and it’s not [Nicholas]’s first test pattern generator. He also created a RP2040-based unit with a VGA connector, the code of which inspired a hacker’s home-grown test pattern generator that was used to service a vintage arcade machine.hackaday.com/2025/12/26/pocket…

    @aral @fabio A powerful storm is expected to hit Gaza tonight. Heavy rain threatens the fragile tents of the displaced. Our souls cry out from the cold and helplessness. Please speak up for us before silence drowns us. We desperately need your help.@evanprodromou @irix @simon_brooke

    Beside the ongoing genocide in Gaza, Israel is carrying out a silent genocide behind prison walls.More than 9,300 Palestinian detainees are subjected to torture, starvation, medical neglect, and daily violent raids inside Israeli prisons.Through routine abuse, the weaponization of food, beatings, dog attacks, exposure to extreme cold, and enforced disappearances, Israel is operating a mass detention system that constitutes collective punishment and systematic torture against Palestinians.#Israel #Palestine #Gaza #Genocide #Palestinian
