DIY Digital Clock Kit, 4-Digit Alarm Clock Soldering Practice Kit

This was the first little project kit I got to try and learn how to solder and I couldn’t be more happy with the results. I learned a lot in the process and the clock worked perfect first try after I finished building it. I definitely recommend it to anyone else who is also interested in learning how to solder and needs a first practice kit.

Lots off fun to build. Learn about functions to set up time, date, alarm. Comes with attractive acrylic case., easy to assemble. Quality parts, PC board and chips. Surprised by how small it is with large green display. Good for practice kit, for soldering.

Overall decent project. Bad: I had to order a 2nd unit to finish it because a capacitor was missing. The instructions could be more thorough especially for a "learning project". Pictures are not very clear and differentiating the parts can be difficult. Setting the time and other settings can be difficult. Good: It works! The display is brighter than I expected. I am new to soldering and was able to do this easily. There was some challenging parts where you have to fit the iron into tight spots without melting plastic connectors (real learning experience).

The electronics assembly went well and the project started up immediately. If you are powering the device from a non-USB source, use 5 VDC (do not use 12 VDC!). Initial programming is a bot complex, but a QR code leading to better instructions was a big help. I gave this product three stars because of the quality of the case. Not all of the holes and slots required for assembly were cut into the acrylic. DO NOT attempt to drill the missing holes (or the missing slots) yourself; you will (as I did) break the acrylic sheets. I did not ask for a replacement case; I did not have confidence that a new one would be any better at this price point. Instead, I plan to build a simple case from stained glass!

I was really surprised at how well this turned out. It was my first ever board soldering experience after just doing some soldering on a practice board. Components fit well and only one area on the board had a tight small bit of space to fit the soldering iron. But everything went together just as the easy to follow instructions said they would. The clock has so many functions it takes a while to learn the many things those two little buttons can do. No missing parts, but no extra parts so if you lose one of those little components you better have some spares available. Overall I would definitely recommend..

I put togeather a 27 Inch tv board by board. With this product it is very hard. You don't get a manual on were parts go, when you contact anybody if you can there is NO SUPPORT. I put 3 of the same clocks together and none worked when i finished. Check and tested every part and inspected for solder problems and still it did not work, will I buy again, NO WAY total junk. Fun to solder and practice on

I bought this in 2023. I did not realize at that time how small everything was. Not sure why brain didn't make that 'connection'. Now 2026 having acquired more knowledge (U of YT) and tools I finally put it together. It was my 2nd soldering project. It was easy to assemble with the instructions. I did go thru parts to make sure all were there and that I knew exactly what was what. So I am commenting on a product I bought 3yrs ago so things may have changed. I felt the instructions were very clear to understand (English). And the pictures were 'spot-on'. It is a very busy board so I did have difficulty putting in the display module and soldering that but it all came out well. Learning to program it now. I have set the alarm and waiting for that to go off. I believe this 2023 module only displays temp in C. Sadly as an American I was never taught nor self learned metric. This will teach me something about temps tho. If it has been updated since I don't know. I was surprised how smoothly assembly went. The case was another story. I felt it took me longer to do that than assemble to clock. Overall, for this item from 2023 I am pleased. The packaging was typical of a lot of these projects... thrown in a bag all jumbled. Some others a very well separated. But again a simple project does not require such packaging and that adds to price. Just make sure all parts are there before starting.

I like it. Has cool classical music alarms built in, looks really nice, but the post-build instructions are terrible. It really wants to be a thermometer and changing it to a clock was not as easy as I would have hoped. Came with everything you need, but ZERO extra, so don't make any mistakes.

This is SMALL...so you need to practice and have the right tip. Not great for a first or second project

Excelente para practical, optional tener una punta Delgada pero no indispensable. Las instrucciones son claras. Necesitarás una lupa para poder soldar bien.

When we tried to build this project for my school project. it WOULDNT WORK!
