  • Works well, bright, easy to use

    posted by jwardell

    The size is actually larger than I expected, LEDs are bright and easy to read. Easily programmed. Physically just what I was looking for to put in my car window.
    Opens easily with four small screws. Remote sensor is easily found and just bend back 180 degrees and resolder. Drill small hole in the back, and now remote works great from the rear, within your car.
    Cheap, works well for the most part. I wanted to keep it in my car to tell drivers I pass to "Hang up and drive" or "Keep right when not passing" but too many keystrokes to really do that while driving.
  • Terrific product

    No more having to use the middle finger for the tailgaters ! This gets the message across very well. Display and remote are good quality. Very easy to program and operate. Manual is only half useful, but the unit is easy to work out.
    Great device to get your message across, and has many applications other than just in a car window !
    If you want to get your message across, this is for you.
  • Works Fine! Included MAX7219 IC

    posted by sebstiaorocha

    Works fine! this came with included max7219 ic and its very easy to use, red display with small size fit my needs, bright is perfect with 5 volts power supply, no visible flicker, brithness control with 16 stages, display hold data and this alow microcontroller do more work, so produtc is very good!.
    Easy to use, size is good for my project, i want to buy it with green display and maybe with bigger display, but i cant find any at dx.com with this characteristcs, so will be great find on future.
    i buy 3 units, im very satisfied with this product, i will buy more very soon.
  • Works like a charm!

    - Easy to transfer text to device, either by included software (Windows) or this ruby-script (https://github.com/ajesler/ledbadge-rb). The script works very well with little to none configuration. - The USB-port is used for both data-transfer and charging of battery- Has both a safety-pin and a magnet on the back which makes it easy to place
    Really useful for small home-projects, or monitoring of local machines.I plan to use this to monitor the temperature when brewing beer at home. For now, I use this to show my local bus schedules in a marquee from my Raspberry Pi.
    Love it! Really easy to start using on Linux if you find the right scripts
  • Buen kit de iniciacion.

    posted by JakoMeister

    Un kit de iniciacion muy bueno y barato. Es muy facil de soldar. No es necesario un skill avanzado de soldar. Facil de montar y conectar a un Arduino o a un Raspberry Pi. Es facil de encontrar en internet en un buscador el codigo con ejemplos para su funcionamiento. Las conexiones hembra que contiene permite reemplazar una matrix o un chip dañado con facilidad.
    Facil, bueno y practico. Un kit ideal de iniciacion de proyectos DIY en Arduino y sistemas similares.
    Buena compra a buen precio.
