Hi Rob.
yea, they are a bit titchy, on that board the 0603 resistor is the smallest and that is what is on the scope kit, the frightening thing is,they come even smaller than that, at least three sizes.
funny coincidence, I just ordered an 858D hot air gun, different make to yours tho. got it off Fleabay.
If you are interested in a review see here.
A different make again but the same thing.
make sure the chipping hammer is sharp before you start. :ddb: :ddb: :ddb: :ddb:
have fun.
Roy.

Hi Roy
Cheers for the youtube link very interesting :thumbup: they all look very generic , my one feels and look canny , not bad for the money , mains lead is a tad short .

You say the resistors come even smaller :jaw:
I have put a fresh flap wheel on the grinder :dremel:

I thought you'd like that, he has an SMD solder tutorial here. &index=3
this is the hot air gun I ordered. http://www.ebay.co.uk/itm/371415508867?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
as far as I can see they all look the same.

RobWilson:
Nice one Roy :thumbup:
Question , How long were you on soldering all those resistors ?
and how do I know which way round the LED goes lol :scratch:
Rob
wheeltapper:
Rob, I think it took me about 15 mins per column.
put 3 volts across the led an see which way it lights.......................only 3volts tho or........ :zap: :zap: :zap: :zap: :zap: once its all done you can put 9 volts from pad to pad.
if you hold the board up to the light you can see the trace.
looking at mine there is a little green mark next to the negative side. YMMV :D
that guy has some very interesting videos.
Roy.
