  • nice display

    posted by prOOwner89

    I like this thing a lot, i had another one in red without the frame and it didn't look as good as this one, the blue color is nice and even, no dark sports, and seems fairly correct to me. The black surrounding around the display is made of the same material as most dashboards so could be integrated very wel in a dashboard without noticing. The display has a matte cover over it to enhance visibility in the sun or bright daylight.
    none
    This is the way to go is you want a nicely finished display with a case to match so you can build it in in something
  • 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.
  • Nice 4 digit display.

    Only takes 2 wires to use. Mine was a Catalex as shown. Had seen some complaints about these devices from various sources, but no problems with this one.Used: http://www.seeedstudio.com/wiki/Grove_-_4-Digit_Display for trial sketchs and nice timer routine too.
    Surprised how accurate a clock you get with just the UNO crystal and no correction. Wanted to do something each day at a time +/- a couple of min.If I have to adjust the "clock" once a week, no big deal.
    Ordered a couple more! Will try w ATTiny.
  • Great Voltmeter!

    posted by michalwu

    Small boardVery good solder -high quality surface mounted, I was amazed really!Useful range (4.5 - 30V is more than I will ever use)No additional power source needed.Low power consumption.There is a trimpot, and you can calibrate it when needed.PCB is very small, but you have two mounting holes on edges!
    You can use it in in many many DIY projects, will fit anywhere!I am going to fix it to home emergency power supply unit.
    I recommend buying this Voltmeter.Will work as expected.
  • Nice metee

    Nice accurate volt meter, this item make me very happy since its a really nice add on to my homemade power supply for my ham radio.I just added it make the cable connection and started working without issues, tested and really accurate for the price.
    would be nice to have it on others colors, but not big deal.next time i would like to find a dual one, like volt-meter and amp-meter so you can read both data with just one quick look.
    Nice packaged, arrived fast and safe.will definitely buy more.
