    Nice job!

    Your video is a great help, as I have a couple of these for practicing SMT soldering. However, the first one, which I've already built, seems to have something funky with the NE555 timer programming components. The circuit calls for .1 uF, but my caps measure at .990 nF, which is not quite .001 uF. The resistors seem correct. Can you tell me what your 555 caps measured as?

    Also, did you realize there are test points at the ends of each row of "practice" components, which are all wired in series, so that you can verify continuity in your soldering job for each row?

    I agree that the instructions should have been better. Mine were at least in English, but consisted of just the circuit diagram and parts list, with no instructions on assembly.

    Thanks for posting this. I've only just started getting into soldering and electronics. I have a few of the Chinese kits and I have no idea how to read it and this will help for sure (my first one I did I guessed … wrongly lol)

    Quick question, what did you connect to this to send it power? Was it just a 9V battery or something more substantial?

    Thanks again ?

    Thanks for this, mine arrived today, I'd figured out most of it, but the challenge has been less the soldering and more figuring out those horrid Chinese instructions!
    Good to see it makes a nice circuit though, and honestly, if mine comes out half as straight as yours I'll be pleased!… Haha!

    Ordering one of these from Alibaba… A$1.36 with free postage… can't go wrong. My last attempt at soldering a sioc8 was a disaster so I really need the practice. Also, some chips are just not made in DIP packages or … are but have 4x the price per unit.
