Review: This digital clock is a kit so be prepared to assemble it yourself. I don't know how many solder joints there are but probably in the 100 joint range. Many of them are spaced 0.10" apart to. I mention this simply so that prospective buyers won't be surprised or disappointed. I considered this to be a "Feature" because I love building electronic projects and this one was easy to assemble and works perfectly. According to the documentation the clock has the following features: o Yellow-green mixed color display * o Automatic brightness adjustment o Time/Date/Alarm/Temperature (temperature in Celsius only!) o Adjustable alarm clock music o Time memory function o Temperature value can be calibrated o Voice hourly report o DIY manual soldering o Simple and easy to operate * I did not see a means in the settings to change the color but it is possible I just missed it. My only complaint, and the reason it got 4 stars instead of 5 stars, is the poor translation of the documentation from Chinese (I think) to English. With the number of Chinese products available in the USA today one would think that there is a company that provides accurate translation services but if there is not many are taking advantage of it. This one falls into that category. The assembly was easy since they provided a photograph of each step showing an enlargement of the component to be installed and where it is located on the circuit board. The documentation does clearly point out any components that are polarized and which end of the device is (+) and which is (-). These components ** MUST ** be installed in the proper orientation or the clock will not work. The problem with the documentation is in the settings of the clock. There are two pushbuttons that are pressed and held to get into the setup area however the only prompting is a title that reads "FU-1" through "FU-5" and you need the printed documentation to know where you need to go and how you need to manipulate the buttons to set the clock as you desire. That section of the documentation is not very clear and I made a lot of mistakes setting mine. Be aware that as far as I can tell the clock only displays the time in 24 hour mode, I didn't see a way to change it to 12 hour mode. I wanted 24 hour mode so it worked well for me though. Likewise the temperature is displayed only in Celsius and cannot be set to Fahrenheit. I did NOT want that so having the temperature on the clock is worthless to me. The clock has to be plugged in to work. It comes with a USB power cord and the end on the clock is a typical 2-pole where the center pin is (2) and the outer shell is (-). Unfortunately it is smaller than most so finding a power supply might be a problem. If you just want it to go along with your computer then a USB connection will work fine. The kit is an easy and fun afternoon assembly project. Getting the six pieces of the acrylic enclosure to stand up at the same time is difficult (Hint! A couple of rubber bands really helps at this stage). I enjoyed building it and I enjoy having it sit on top of my monitor. If you have kids it would be a fun project to spend an afternoon constructing it with them.
Review: When we tried to build this project for my school project. it WOULDNT WORK!
