  • 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.
  • Nice digital clock

    posted by tacalin

    Nice clock for the purpose I've purchase. I just replace my cable PVR and lost the clock on display and this little one do the job for me.No bulky case needed since the board is the same size as the display.
    The display it's a little bit too bright with 5V for a semi dark room. I'll try later today with 3V and see how is looking. The temperature looks to be accurate but since my unit it's stick on top of a media player I'm not using this feature because the display temp is few degrees higher than the room temp.
    Happy for now.
  • Very good device! Very useful for geeks!

    Very good quality of assembly. Very useful manual with much of tables of POST-codes. Works with LPT-port on some motherboards correctly. Two POSTs on the display.

    f you are repairing motherboards, this device will be so helpful! Coupled with a very large list of POST codes in the manual - it will be a very good acquisition.Attention! These card is NOT SUPPORTED reading of POST-codes by USB interface! The USB-port is only required to supply to the card the +5 V!
  • Nice cheap timer relay

    posted by mr22turbo

    Great price! Screwed one open and the electronics on the inside are well made.Its possible for the timer to count down or up to the set time. Timer can be set in seconds, minutes and hours.
    There are different types of timers, check the product number, this one needs AC220V as a power source. Timer has possiblity to hook up a reset and pause switch. The relay can be connected as normally opended as well as normally closed. English manuals can easly be found on the internet through the product number.
    Great product for a great price!
  • 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)
