Warm tips:
- Before soldering the LEDs, it’s recommended to use a multimeter to check if there are any LEDs that are not bright.
- Please make sure all components in right direction and right place; and check whether pseudo and float welding, this is very important in practicing and testing.
- If you need technology supports or meet other problem, please send e-mail to us, we will help you as soon as possible.

Step one has one blurry picture telling you where to put 11 resistors of 6 different values.This is beginner friendly? Is there at least a high res picture somewhere? Even if there is, there should be step by step instructions for each type of resistor. I might not even try this, as it does not appear to be beginner friendly at all.

Great soldering practice. All red LEDs, the pictures vary. The T-1 LEDs seem a bit overly sensitive to heat — I killed a few getting them soldered in right. Fortunately there were more than enough extras included!

This was a fun kit to refresh my soldering skills. The board was high quality and all the components were there. The instructions were straightforward, clear, and easy to follow, even though the author is not a native English speaker. I could not find the four triode tubes called for in the instructions, so I made do with the four NPN transistors included.I would suggest installing the ICs before the rest of the components. It was tricky trying to fit the leads in the small holes with the other parts in the way.I had one LED not light up. Since I destroyed it during replacement, don't know if I put it in backwards or it was defective. There were spare LEDs, which was nice!If the power supply socket is installed on the silkscreen side per the instructions, the ground is not connected to the B- power solder hole. I put a jumper between the two outside holes of the power supply socket which fixed the problem.I recommend this kit as a fun project. We will use it as a game timer / conversation piece. Take your time and make sure each solder joint is good!

The instructions were clear and concise with pictures showing layout of all components and a detailed parts list that even had what the actual components were labeled as (what is printed on the component) - the board was also well labeled. I bought this kit to brush up on my soldering skills as it has been several years since building anything. I overheated 1 led soldering (or maybe had it in backwards) and destroyed it taking it out, but the kit came with 4 or 5 extras so all good - as a bonus it even works! This was a fun kit to put together.

I don’t get it. LEDs are the last to install but the only way to know if you failed or not. The only test to know if u messed up or not. Resistors, capacitors, diodes, etc are all first in the instructions before you move on to the more non-essential components.No additional parts are sent in case u mess up so order a new kit if you do. Instructions are last luster and require ur own research!Instructions provided do not adhere to a new learner what so ever and inquire independent research for a “learners kit” but not resources included.Order multiple kits so u can practice. I only got by because my boss knows soldering but even then I ruined my first kit because I messed up one piece and no extras of anything were included.A $10 soldering kit has a suction kit but one extra piece for each step is not necessary? How do I learn without messing up?This is basically a “test yourself kit without messing up.”I’m not at that point which is why I picked up such a kit, now I’m out money because the kit doesn’t inform u precisely.

Just got into soldering, this was a great place to start off. Easy to assemble, lots of fun to put together and see it come to life. The only issue I had was with the buttons, they don't work at all, and the instructions are not very well put together, I just soldered according to the pictures.

Great fun to put together (well, the 60 LEDs get a bit "old") and all parts as expected. The instructions do not seem to mention D61, a red LED that flashes when the PAUSE button is active.But here's something to watch out for. I tested it using a power brick. The timer seemed to work fine for about 30 seconds, then "go crazy" with the LEDs only dimly lit, and illuminating far more frequently than one per second.I thought I had messed up. Then, finally realized, the power brick was putting itself to sleep after those 30 seconds. (The current draw of the timer is so small the brick shuts off, thinking nothing is connected.)So if your circuit works, then stops working properly after 30 seconds or so, and you are using a power brick, you may be having this same scenario. You would need to put a load on the brick to keep it awake, or use a device that pulses a load every 25 seconds or so, to force it to stay on.

Easy to assemble. Lots of fairly close soldering, but well laid out. PC board is well made. Instruction sheet isn’t too bad, could be better, though. No instruction for use, just assembly. Not much of an issue as it’s pretty straight forward, and the switches are clearly identified on the board.I’m not sure what the finished product is useful for. Perhaps for timing turns in a game?
