Dingdong Store DIY Electronic Clock Kit, Soldering Practice DIY Timer Kit Digital Clock

This is a great project to improve your soldering skills. The operating instructions need to be improves but assembly was easy.

Good for the experienced builder. Would be challenging for a novice. Worked fine when completed. However, the temperature reading is low by 9 degrees. No way to calibrate the reading. Other than that everything is as it should be. Since I just completed the kit, no way to comment on clock time accuracy. Great value for the money spent.

Nearly all aspects of this are great. The instructions are easy to follow. The PCB clearly identifies where things go and it works just as described. The down side is that the case doesn't fit and I think there was an error in the case parts sent because there should be side pieces that are tabbed and slotted but I only got 4 tabbed pieces and they did not interlock so while the clock is nice, the case just doesn't fit together.

I am a tech nerd and thought this would be cool on my desk at work. I was disappointed. I soldered on the components and plugged it in, 4 leds didn't work. Replaced the leds and they still don't work. You can't program the time in because the firmware doesn't work like it is supposed to. If you want to solder 60 leds and a bunch of components just for the soldering sake, then this is for you. Otherwise POS

At first the instructions seemed lacking. But the way the circuit board is labeled along with the instructions make it super easy. I have a modest level of experience with electronics and soldering and it wasn't difficult to understand the instructions. I think I spent about seven hours soldiering. But assembling the case was a challenge. Take your time and don't try to force the nuts into their slots, or you'll break the side piece like I did. Overall, a fun little project to work on my skills with a soldering iron.

This might not be for first time builders. If you are comfy at soldering small things, this is a good afternoon project. You can change how the second hand lights work around the clock. In the USA we use 12 hr time. This clock uses 24 hour time. 13 is 1 PM. 14 is 2PM. I wish they could have given the choice of 12 or 24 hr time.

Gave numerous solder connections for practice. Clock chip, however, gained 1/2 hour in 2 months.

The kit will certainly let you hone your soldering skills. There must be at least 160 locations requiring soldering!No much in directions provided other than the narrative. If you work orderly you should have no problem. I needed to watch a you tube video to determine which piece was the thermistor, then verified by process of elimination.I tested all the LED's as the instructions suggested and found they all worked. It was good a few spare LED's of each color were provided, just in case there is a failure down the road.Clock worked as advertised. But note I found assembly of the plastic case perhaps the most challenging part of the kit. Looking at the plastic pieces initially, except for the back panel, one would conclude they are all symmetrical, but alas, they are not. The front and back panels have a larger margin on one edge which I realized after a couple of false assemblies. Also, peeling the protective film off of the plastic pieces was difficult. With patience use you use your fingernail to lift a corner. Most of the film comes off relatively easy, but several of the film sections tore off in pieces.
