Digital oscilloscope project/kit

<< < (50/70) > >>

PekkaNF:
I got one scope kit yesterday.

I was just eyeballing the PCB. Should have a cunning plan for the external rigger signal, but I want to assemble it as "standard" now. Display comes over it, not too much space for connectors or standoffs.

There seems to be some "optional" connectors: Like Mini USB and some for programming. Anyone used them?

My SMD kit arrived today ,,,,,,,,,,,,,,,,,,,,,,,,,,,,F*&k me  those are bloody small components Roy  :palm:

They are going to take some welding  , 3.2 mm  7018 rods should do the trick  :lol:

Hi Rob.
We never heard how you got on with those SMD components.
You must have finished by now. :) :) :)

 :Doh:  Hi Roy ,

 I have had a wee practice using the hot air gun and solder paste with  mixed results  :(  , looking for a way to apply just the  correct amount of paste .

too much , wire feed a tad high  :lol:



looking a bit better , placement is a bit wonky  :palm:




I am using a stereo microscope to do the work , I think I need glasses  :palm:



I may practice a bit more this evening , things are a bit slow at  the moment as I am pulling my workshops to bits to make room for new machines  , like this wee beastie   :)

You've got one upside down! all the pixies will fall out. :lol: :lol:

Nice looking drill press, is it a recon job or just chuck it in a space and use it?

posh microscope you have there,  :drool: all I've got is a MK1 eyeball and a magnifying glass. :bang: :bang:

Roy.

John Rudd:
So opinions please on the hot air rework unit ?

Are they good, rubbish or something else?

Nice effort Rob, half the trouble is placing the little blighters and getting them to stay put..... :Doh:

Then soldering them without dislodging.....
