Gikfun 6 Bits Digital LED DIY Kits PCB Soldering Practice Learning Board AT89C2051 FR-4 for Arduino EK1323

Has great ability to start out soldering and figuring out if you like electronics

I am fairly new to soldering and this was my first kit. This kit does not come with instructions on how to solder nor are the assembly instructions particularly easy to read. I was fortunate to have someone with me who was experienced with soldering, as well as a YouTube video I found after putting the serial number of the circuit in the YouTube search bar. Once you see the circuit in the video, and get an understanding of basic circuitry, this kit was a fun little introduction to soldering and, even with my minimal skills, was not to difficult to complete. I would recommend this as a beginner, it’s a fun and somewhat easy build, but YouTube tutorials are a must if you’re new.

This is a fun and easy build, some of the parts were faulty, but, that goes with any electronics kit. I did have to replace all 4 LEDs due to accidentally having my soldering iron to hot. The only problem is this thing is a power hog. (I have used up at least four 9V batteries running this thing)

The components must have been in stock for a long time. the leads were covered and I felt needed to be scraped for a good solder. Some of the values of the resistors were out of tolerance and I replaced them with better quality. The time gets ahead by about 60 seconds per week. This is a great build for beginners to learn soldering techniques.

This thing came fully assembled not in pieces as the pictures show. Also there were no instructions or anything. DO NOT ORDER THIS AS A DIY "TEACH YOURSELF HOW TO" KIT!

I purchased this kit for the 4021BH 7 segment dual digit displays to replace burned out displays on a fridge. These are nearly impossible to find with the correct pinout unless you buy 100 from Alibaba... The kit came with 4021BS displays, which are the "super" red versions (brighter than the 'BH). The pinout matched, and they look great in their new home. I also have a bunch of other spare components left over as well for future projects, which is a bargain for the price, considering 2 of the display modules would have been ten bucks by themselves, minimum.

This was a fun practice project, relatively good quality - I would buy again since I have spare parts.I have some tips:1. You will need to buy your 9v power connector separately if you don’t have one laying around the shop.2. Check your LEDs before you solder (easy to do with multimeter) - 2 LEDs were bad in the kit I received.3. If you are buying for beginner practice - pay close attention to the parts and silkscreen location markings, particularly the transistors (don’t assume just because 2 components look alike that they are the same).4. Another beginner note - make sure you get good solders all around. The through hole solder on the IC will connect directly to the resistors above the IC, that isn’t an accident - If some of the lines aren’t lighting in your clock numbers check you solder points for a bad connection/cold solderOh and the alarm defaults to something like 11pm so don’t forget to change that or turn off when you power up, or you may find grumpy roommates the next day :)

A beautiful well put together kit. Easy assembly great soldering practice. All parts were there and instructions were adiquite.

Very nice and organized project for beginnersWould highly recommend!

Got everything installed correctly and all the functions works perfectly. Great product! Will buy again.

This was a fun little project to get back into the swing of things. Not to difficult for a beginner but challenging enough to learn something new. I will be ordering another one of these for the kids! I recommend learning some basics about circuit diagrams to make sure you understand some symbols, etc.

Sure is fun to build, works really well and is quite bright, but i was surprised how quickly it drained a regular 9v battery, like in 4 days. Better to take an old usb cable and weld it in place

Soldered this Digital LED clock together with no problems. Instructions were good for assembly. The PCB was of good quality along with the components. After assembling tried a 9 volt battery on the clock. The clock lit up with no problems, but the battery only lasted about 18 hours, Suggest using a USB power source or something with more capacity (amp hours) than a 9 volt battery.
