Curse you David Jones!

[vpelleri]

 I recently ordered a Rigol scope, and having spent most of my money, I thought I'd save a little and build a function generator from a kit. I've heard and read Dave say on more than one occasion that if you build a kit, he hopes it doesn't work. Well, congratulations Dave, and thank you! I have a perfectly non-operative function generator sitting on my bench.
 
 I only wish I had a huge spider to go with it!

Well, with the Rigol, you have the perfect instrument to debug your function generator. Plus, on here, you have a team of people all round the world waiting to help you out. I'm not sure about Dave's spider, but my wife would totally freak out on one a tenth of that size - and it would be my fault

If you don't know WHAT is broken, than I ask myself why the hell you bought an Rigol Scope...

If you could say us, what does not work, you could have a slight shine of hope in this forum, that someone might have an solution for you.

Whining alone DOES NOT help!

Lol, I don't think the point was to complain or to ask others to fix it, but to share the experience of something going wrong.

and a perfectly non-operative brain.

Don't worry vpelleri, it's just their way of being friendly towards you

Perhaps you could explain a lil' better as to what's going on with the FG? As mentioned previously there are certainly some friendly & knowledgeable guys around here who will likely be happy to offer some opinions.

Oh and welcome to the EEVBlog

I'm happy to help 

The first piece of valuable information would be ... is it scratch built on 'veroboard' or a kit built on a PCB. That latter is often easier to fault find on and the Veroboard has the added complication of correct strip cuts and link positions 

When fault finding on a relatively simple design I would always start by checking all solder joints (I have even been known to miss soldering the odd one) and looking for solder bridges. I would then check that I had the correct components in the correct locations, taking note of capacitor polarities and semiconductor pinouts. I have seem some hobbyists caught out by kit suppliers or electronics shops supplying a different pinout transistor as a near equivalent. From memory I think the BC182 and BC182B have a different pinout, but I may be wrong as the memory is fading.

Describe your project, show us the schematic and a picture of your PCB and we will try to help. If that is your wish, that is

 Thanks everyone for your responses. I've figured out the problem, there are two resistors, one is an 82K resistor and the other is an 8K2 resistor. I have no idea what an 8K2 resistor is, so I thought it was a missprint on the plans, It's KIT-23 from Kitsrus dot com.
 My original posting was to chide Dave for his newbie curse and hopefully make some friends while doing so.
 Thanks again for your kind attention!

8K2 = 8.2K

[LewisS]

8k2 is a shorter method of writing 8.2k ohm resistor. It is used a lot because it is shorter and it can be more accurate since sometimes it can be hard to see a . (dot or period) on very small components or solder mask labels.

Exactly the same with my girlfriend

Any way, does it work after changing the resistor ?

[vpelleri]

Yup, it's working!

[Fraser]

Great news, pleased to hear it 

You are amongst friends here and most are very helpfull.

Would you like to expand on MOST? Lol. Welcome to the forum and to quote jeri 'Failure is good'

[Mechatrommer]

Yup, it's working!

the brain right? welcome
