Your cart is empty. 1.This DIY assemble kits is equipped with 6 digits LED module, it's fun to build and also help you learn more professional knowledge about electronics.
2.It is programmed AT89C2051 MCU chip, precise time display, 24 hours format, supporting seconds correction, countdown clock, stopwatch, counter, hourly chime and alarm clock functions.
3.High quality PCB, has clearly marked the electronics components, even beginners can easily successfully.
4.Before the LEDs, it’s recommended to use a multimeter to check if there are any LEDs that are not bright.

Pretty basic with not so great instructions...Fairly easily to assemble if you have any kind of electronics experience and a decent soldering iron.I have a professional setup and this was a breeze for me.After about a month comparing the time to an atomic clock and my cell phone, this board was off by 6 seconds.

When you are learning to solder it is good to start with wires and perhaps terminals that can stand a little too much heat, an almost universal newbie mistake. With a little practice most people want to get to the main event, soldering components to a printed circuit board. This kit is ideal for that purpose, it features a simple single-sided pcb and includes a wide variety of through-hole components, like resistors, capacitors, LEDs and three LED displays. There is also a single IC. And to protect this from overheating the kit provides a socket to be soldered to the board. Of course there are connectors and a battery holder as well. Perhaps best of all, after you assemble the kit you will have a simple 6 digit clock to play with.The kit is inexpensive but of reasonable quality, the packaging had no crush protection but everything was okay in my case. The quality of the pcb is reasonable, silk screened with clearly labeled component positions. All components were complete and seem to be standard. Just two criticisms; the red LEDs that sit like colons between the pairs of digits are not in line and look strange. Also the instructions are 100% Chinese. Fortunately I snapped a picture of the instruction sheet and used the translate function on my iPhone to check that there were no special instructions. Assembly is straightforward.Recommended as a practice kit, if not a perfect looking clock. Packaging was double layers of plastic bag.

I have assembled quite a few electronics devices in my 50+ years so I don't think I made any rookie mistakes with this kit. It took me about an hour or slightly longer to stuff all the parts onto the board and solder them in place and clip off the long leads. One of the S8550 transistors was missing but I had one on-hand to use in the assembly.Double-checking the assembled board for IC, capacitor, transistor, and diode polarity, for properly-completed solder joints, and adding the final jumpers (wires soldered to the board on the front or back between holes as indicated) I felt like everything was complete. Also note the pushbutton switch should be installed with its "legs" to the left and right in case you're wondering.After powering it up, first with 5V, then 9V, I got nothing.I inspected the board and found that the input voltage was not making it to the 78L05 Voltage regulator. I resoldered the joints at each end of that circuit board trace, but still nothing. After applying voltage directly to the input pin of the 78L05 (on the left edge of the board, looks like a transistor) I got the project to light up.Apparently, despite looking normal, the printed circuit board had no continuity in its main power supply circuit trace leading to the voltage regulator.Upon installing a little backup battery and applying power, I can see that the microcontroller starts up and wants you to set the clock, but just as the pc board trace to the main power supply input was not working, there appears to be several other traces that are feeding the 7-Segment LED elements that are also not connected-through, again, despite re-checking the solder connections on each end. Also, the second set of two discrete LEDs did not light because one of them was defective and they are wired in series.I will say I like the design of the kit and I was looking forward to having it around as a clock but that will depend on my willingness to debug the circuit board at this point.So, with no documentation, one part missing, at least one bad part, and multiple bad traces on the board I received, I can't recommend this as a fun hobby project, particularly to a beginner. I believe it would be very frustrating for a beginner to assemble a device that may or may not work due to production quality.

I really shouldn't have more expectations from an $8 kit, but not having any documentation in English was a disappointment. You might still be able to finish this kit using the traced lines on the printed circuit board, but they could have at least tried to run this sheet through an online translator. Anyways, this kit came in a small plastic bag, and hopefully with no parts missing (hard to confirm without a BOM). I hope they can add a web URL to their listing to direct customers to some additional information. As is, buy at your own risk.

I think there are some issues with the PCB and I wish that I had taken the time to test the continuity on the PCB before soldering all of the components on the board. I think this was a great board to practice soldering components onto and it helped me improve the quality of my soldering but I wish that I was able to get it to work.

The ACEIRMC Digital LED Electronic Clock DIY Kit is a fantastic way to learn about electronics and practice your soldering skills. The kit includes all the necessary components and a clear PCB, making it easy to follow along and build your own functional digital clock. This is a great project for beginners and experienced hobbyists alike, offering a rewarding and educational experience.

The kit looked ok. Instructions were a bit lacking but the quality of the parts looked ok. Unfortunately, the PCB (printed circuit board) was defective and the traces lifted and came apart when I tried to assemble it. Obviously with damaged traces, the clock won't work. I didn't have the energy or time to try to fix the multiple traces so I threw it out. Disappointed.

I haven't had the chance to put this one together yet. But everything is in the kit and it appears to be good quality. I'm excited to put it together.
