I bought this to refresh my SMT skills after some years away from doing it as part of a job. It certainly is a challenge to get back into the flow of assembling something like this. Completed the build, powered up the unit, and it ran for about two minute before the magic smoke escaped out of something and the 4017 overheated. ;P A partial LED short it looks like.
So now its a circuit diagnostic trainer. lol! It might be helpful to have a few spares of the parts that may be more heat sensitive, or prone to fail when running. But its an $8 kit, so can't expect too much.
You will need a 20x magnifier to inspect for solder defects, as well as a reasonably good temp control solder station, an assortment of soldering iron tips, an assortment of tweezers, flux, solder wick, and an anti-slip surface to work on to be able to complete this device reasonable well. 60/40 tin/lead solder would be recommended, but if you want to try doing this with RoHS solder, you will likely bump the difficulty from an 8 up to an 11 unless you're using a hot air system, or other professional soldering station equipment like a Metcal.
