5.0 out of 5 stars Great for practicing
Purchased this for my son to practice soldering, put the clock on upside down but just ignore that lol so i think thats why we only have 2 digits on the clock otherwise good cheap wee bit kit to mess about with
1.0 out of 5 stars Does not keep accurate time
Foolishly I did not read the other reviews before ordering. I built the kit and it works except that as others have reported it runs slow. In clock mode it counts up to 60 seconds over a time period of about 2:15, which suggests it probably needs a 27MHz crysral rather than the 12MHz one supplied. I might try fitting one to see if it then runs properly.
2.0 out of 5 stars Set up?????
Regardless of programming, the "seconds" digit would only advance after 2 or three seconds, Minutes well after over two minutes.Setting up instructions are non-existent?POOR but enjoyed the build.Switches need identing?
5.0 out of 5 stars simple to put together
easy clock great for bit of diy
3.0 out of 5 stars Clock speed
Easy to put together but the clock speed is not working properly checked all components and changed the crystal the only thing it could be is the main chip
1.0 out of 5 stars No instructions
Bag of bits with a diagram and instructions how to use the finished product. Nothing step to step about building
5.0 out of 5 stars I really enjoyed
It’s good to get into soldering and it’s good for money
2.0 out of 5 stars Disappointing
Bought as a gift turned up in a small plastic bagDef would not of bought if I would have known this def not worth the money probably won’t work either may just cut my loss and put in the bin def won’t be giving as a gift
It was fun to put it all together
Recently I have been dabbling in video game console repair and modding. I got two of these o e for me and one for the kid so we could have fun together. I ordered at the same time but they shipped in two different packages arriving at two different times. I went a head an assembled mine and I must have got a dud because mine won't even turn on. Hopefully his does. If not I'll be contacting for a refund.
Serve apenas como exercício de soldar
Não sei se fiz alguma coisa mal, mas um dos dígitos não acende.Para além disso, tal como reportado por outras pessoas, o relógio não funciona bem, demorando vários minutos para passar um minuto.É apenas útil para quem quiser experimentar o processo de soldar, sem se arriscar a estragar uma coisa valiosa.
Che l'articolo sia come da descrizione pubblicità.
Non ho nulla da dire, tutto perfetto.
Preis ist OK. Macht viel Spaß.
Ist ein gutes Produkt zum löten lernen einfach aber interessant. Gute Sache.
Notice absente
Il serait bien d'avoir une notice d'utilisation.
