display red Customers Reviews

  • Handy little meter

    posted by astroberi

    Bright, accurate, and very easy to install voltmeter. At first, I ordered one, then two more. I use them to monitor battery voltages on steadycam LCD monitor and lights. Third one is installed in UPS. Can be installed anywhere that needs voltage monitoring form 4 -30 V DC
    This is a panel mount version, if DX offered a fully enclosed version I am sure it would find many customers. A module only (no case) version is also offered on the site, with red and blue displays respectively.
    If you need a easy to read (esp in dark) cheap and accurate voltmeter, get it.

    They are cheap, they´re very well constructed, and they have a little label to protect them.Its brightness is intense.The pins are standard so there is no problem connecting them to an existing device.Have no doubt in purchasing one of these.
    I haven´t tested the all 10 parts, but I hope they all work like the one I have tested.
    If you are looking fot some good 7 segments leds, this is a really good option.
  • simple USB consumption measuring

    posted by mkobylan

    looks like standard USB flash memory so you should not have problem to push it into any USB port0.1A 0.01V measurement resolution
    producer should think of next generation with different display module
    it's too long so device you are connecting is bending/pulling USB port down - I would rather buy something smaller (I don't need digits 9mm high)
  • Great music box!

    One of the best sounding music players of that size I've had in my hands. It's small, well built and after some time easy to use. Also the battery (standard Nokia-like BL-5C type, so it's easy to buy and replace) can keep the device playing for amazingly long time. It's definitely worth of its price.
    I think that international shops like DX should sell products with at least English localization. I mean for me it was no big deal and it was a bit of fun to find the right way to flash this device, but ordinary users probably won't manage to find the correct firmware on chinese pages and the way to flash it and will be disappointed with this otherwise good product.
    To set this player to English language, you have to go to main menu, select the most right icon (the one with wrench - settings), then select the third item from the top and then select second item (English). If you have only one item here, you'll have to flash your device with newer firmware to get English language. This firmware can be only found in Chinese version of manufacturer's website - http://www.hb2099.com/
  • Great gadget for geeks.

    posted by Brepta

    Simple, relatively small and primitive to use.Accuracy not tested, but looks usable.Clear plastic case looks great.
    Symbols: u means U, A is A.Waiting for your favorite number is ugly.Will be nice to select/switch display mode by button and use full 4 digits for V and A measurement.
    Microcontroller processor can't be identified, has no label on case.I will try to reprogram it.
