hello, i am from colombia, i have 27 years old,I lived on a farm, due to the war of my country I had to leave  to live in a town,i started studying computer repair technician. I can now diagnose most faults but  would be helpful to have a oscilloscope.

Good idea. If people want to thank posts to indicate their preference, then go ahead.

All the best to the entrants. Hopefully, if the winner already has a scope, they'll pass their existing one forward to a less-fortunate and deserving electronics enthusiast. :-+

I am more than willing to pass my current scope scope to somebody I know who deserve it. That is if I will be blessed with Dubbie's generosity.. :-+

Haha good question. I upgraded to a Keysight mso3024T with all options which I got for a very good price. I have to say, I was kinda surprised that the new scope doesn't feel as solid to me as my Rigol. I also keep reaching for buttons and knobs in the wrong place. Oh well, I am sure I will get used to it!

I have a MSO6000 at home while at work we use a MSOx3000. I constantly have the problem of looking for the button in the wrong place as the 3000 uses basically the same menus, just all the knobs and buttons are in different locations. I always know exactly what button i want to push but my finger just cant find it.

I think i still prefer my 6000 because its esentaly the same scope that has no wavegen but boots in under 10 seconds.

It would be a good idea if the winner is commited to send the oscilloscope to other person(according to original owner decision) after 6 months or so.

Or you could ask the winner, to write a report about the first big electronics project that was taken up with the scope, with details on how the scope was a real enabler for the project. The report could of course include the necessary photos to make it more flashy :)

Next to the report about the actual electronics project, the winner could provide detailed feedback on the scope itself, what is good or bad in the user interface, the controls, features, performance and stability.
This review could also include some photos to detail out the findings. If the winner already had a scope before, the review could include a comparison between the two scopes :)

Both the report about the electronics project and the review about the scope itself, impose a commitment, but provide means to show that the scope found a good home and has an excellent future moving forward, with the opportunity of working on many cool electronics projects :)

Maybe one of these upcoming electronics projects include a repair job on an older scope.
The winner could donate the repaired scope to the next person in line in the scope chain :)

I like the idea from pascal.

Shipping scopes around in 3rd world countries can be expensive. Even getting things across the Atlantic can get pricy (I recently payed over half a grand for shipping of a 50kg spectrum analyzer from the US)

But i think it is more than fair for whoever gets the scope to write a nice big post with lots of photos that shows what the scope allowed them to do. It would be a great way of saying thanks to the guy who gave it and perhaps encourage someone else to do the same.

Really guys, Rhys is giving away a scope that is worth several hundred $ here in NZ and prepared also to subsidise shipping to the tune of $50, a pretty generous offer IMHO, just how much more of a deal could you ask for? Know that the package will be ~5 kg or a bit less and if you aren't prepared to cough up the rest for shipping well find one closer to home.

Rhys you've impressed us all with your offer.  :-+

Hi Dubbie, I didn't think I would be signing up to EEVBlog before I saw your thread and am not sure if I qualify, but I'll give it a go.

A bit about me, I'm relatively new to electronics but it's something I have been building on over the last few years. Been somewhat forum shy in the past as I have a ton to learn and it is still a little intimidating, I'm slowly picking up more advanced concepts however and self studying under my own pace.

My main interest which may be a bit unusual (perhaps not in electronics) is continuing on my own design high voltage supply that I have piecemeal from other circuits. Not reinventing the wheel here but I am adding my own unique safety features (down the track I may collaborate further on this). 

My situation is that I'm on retirement pension and more recently due to a bout of illness am now left with very limited mobility. This last year has been mostly a write off in and out of hospital but it looks like I'm through the worst of it. Because of my situation I will not be able to go out and spend money on a new oscilloscope (have to prioritize). I had a hard think would I make a good candidate as I don't have youth on my side and my working and income earning days are over. But one thing I do have though is lots of time to experiment, so it will be well used and cherished. 

I don't own an oscilloscope and my current electronics equipment comprises of a limited bandwidth multimeter (it does have capacitance) a soldering iron and a few basic tools. So as you can probably figure, I'm working in the dark here when it comes to testing control circuits, not only that I have no function generator so this would be a double win and looking at the forum exactly what I would buy if able.

I don't have a setup that compares anywhere near the others so photos aren't going to do much justice to my application, am still trying to get a grasp on uploading as well. If I'm fortunate enough to be considered I'll be sure to figure it all out and produce an adoption photo. Not calculate I know how much it will cost but shipping should hopefully stay under the $50 limit.

Anyway, an oscilloscope would be a considerable boost and take my hobby in directions I can't even imagine at this point. Here is hoping, and my fingers are crossed. Good luck all.

Fred.

This offer has closed now.
Thanks for the responses.

I'll post up the results shortly. Unfortunately I am being slammed at work right now!

I'm sorry Fred, while I empathise with your situation, I began the givaway with the rule that it was for non first-world citezins only. You're not the only person to have asked and it would be unfair to change the rules halfway through.

That leaves 5 eligable entrants.

I have to say that I kinda hoped that one persons story would stick out and be an obvious choice! This hasn't happened and I wish I had 5 scopes to give away. Unfortunately I only have one. So with nothing distiguishing one person above another, I have decided on an overly complicated and idiotic scheme to let the scope pick the winner :D
I realise that some of the entrants already have a scope. I don't feel that is a disqualifier. Everyone wants to upgrade sometimes! I only hope that the old scope will go to a good home and not under the bench to gather dust.
I fed a noise signal from my signal generator into the scope. Where the trace crosses the horizontal grid marks, I have treated like a clock. If the noise is above 0v, I have recorded a binary 1, where it is below, a binary 0
I stopped the trace 5 times. Each time I stopped, I assigned that binary number to the contestants in order of their entry. The highest number wins.
Let me point out, that if I made any errors manually decoding the trace, take that as an uninentional extra layer of randomness!

You can check out the video to see who scored the highest!

https://youtu.be/zJMJLdvbvEQ

If the winner wants to PM me their details, I'll get this sent out. If I get no response in 48 hours or no satisfactory shipping arrangements can be made, the prize is forfeit to the next highest and so on.

It would be nice if the winner would post some pics of them using the new scope!

Winner, winner, chicken dinner! :)

Very very original way of choosing a winner! Much more original than KeySight did during their Scope Month.

Maybe it is an idea that the OP adds " - Competition closed and winner selected" to the initial title.

I live in one of the excluded countries, and I got my scope for pocket money from someone who practically, if not exactly, found it in a dumpster (which elex_enthusiast reminds us doesn't happen everywhere).

Did anyone else notice that 3 of 3 lab photos from our friends in non-excluded countries show a hot air station?

I'm feeling a little underequipped...

Mine is so much cheaper than hakko branded (which is so rare here in my country). It was gifted to me by my father when I was in college. I think it cost more or less Php4,000 (at about US$85 current price). It's still worth it, I've been using it for several years now.

Everyone should have one these days. I bought a Atten brand one on ebay for 50 bucks way back, still works just fine. Well worth the investment if you work with any SMD stuff, but its also useful for things like heatshrink tubing or removing stickers etc. No need to get the fancy expensive ones.

Yep, I would have thanked one (or 2) if they had stuck out for me.

Edit ! Obviously, I thought all 5 were all equally deserving, - not none of them!

In the past when I've given small things away like unused PC cards, I've posed a difficult puzzle  >:D nobody's ever given the right answer, so I've had to come back a few days later and say 'OK, first one to post then'.

Perhaps you should have used more of a optimization problem so that you can get multiple solutions but grade them on how optimum it is. Like make them design a swithcmode converter in TIs webbench for example.

Wow ! Still can't believe I won it, thank you so much Rhys.  :-+

Suggestions on contributing back to the forum, definitely, its just currently I can't promise the exact time line, for sure when every time there is project/task/question or post in the forum that related to scope usages, I will use this scope and write down accompanying credit to Rhys.

If anyone want a high resolution tear down and close up photos of this scope, just ask, I will be happy to do it for the forum.

Rhys, PM sent regarding shipping arrangement.

Damn, I guess I can't sleep too well tonight as probably will still feel overly excited and happy.

Again, thank you.  :-+


It would be nice if the winner would post some pics of them using the new scope!

Sure, will do once I have the chance at home with the scope arrived here.
