    Nice hackeable gadget!!!

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Cheap, hackeable and cool. I can make some fun stuff only adding an accelerometer and replacing the atmega8 by an Atmega 328 with Arduino bootloader. You can see a cool hack at http://www.radikaldesig.com/2012/08/22/sistema-de-particulas-en-matriz-led-con-a...
    Cons:
    Could include a 5v Regulator to prevent possible over voltage from people without electric knowledge

    Nice led matrix for DYI

    posted by mpsaren on 07/26/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Works. Arduino drivers available, but layout of matrix differs from sure 3208 matrix and minor modifications are required. Performs well and is relative cheap.
    Cons:
    Build-in application (clock) is useless, since oscillator quality is not good (time differs several seconds in a day). Be caref...

    well, the month/day character is in chinese, but as the unit is from China, I'm not sure if this is a con; next time maybe just...

    Nice for own projects

    posted by DrJones on 03/04/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Nice module with a nice LED driver. Comes with an ATmega8 just waiting to be programmed by you. Includes an ISP header. There are spots on the board to add several components like a temperature sensor or a battery buffered real time clock. Three buttons.
    Cons:
    The original clock software is a matter of taste, but the date display with chinese symbols is a con for most. Bought it for pr...

    Great little gadjet for the Hobbiest

    posted by RDCES on 01/30/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Out of the package, it behaves as a clock/calandar. When powered up with a 5VDC source, the unit will display the time then shortly afterward scroll the date. The time and date can be set by pressing the top button to go into settings mode, then pressing ...
    Cons:
    It would be nice if DX would have at least provided a link to the source code on the mcu. It would give people an idea of how ...
