Nice kit, although you need a fine soldering iron. Could do with instructions but a bit of googling and it was sorted. Didn't work though. Put it down to dodgy soldering, tested the components, eventually cut them all off and soldered without a board, still won't work. I can get a reading with a multimeter just not enough to light the LED.
Well take it to work and try it with a 3cm wave transmitter.
This kit plays twinkle, twinkle, little star and flashes each color row separately to the music. Do not put the jumper shown in the image unless you want to disable the sound. Fun kit; not much to it, but it did give me a good go at SMT soldering. So much so, that I will not hesitate to go on to bigger projects like I had been. Single document is the schematic not much else needed since components are marked on board. 5V 160mA.
I bought this kit for my sons to practice soldering. Loved every minute. Not complicated and just the right level of components that they do not get bored or overwhelmed. The light pads are detachable and you can wire them up separately from the board. My sons detached them and added them to their favorite toys.
Bought two had problems with one of the IC's. I decided that it was not to my advantage to try and get a replacement. ICStation was willing to help so I give them high marks for their communication. Very timely and personable. Basic clock. Fun to solder not much in the way of functions. Only black mark is the lack of documentation on programing it, but easy enough to figure out with trial and error.
