That is unfortunate to hear that the site is no longer around. 

 

As to the light socket incident, I can only imagine dealing with 220V over 110V.  Thankfully mine was a direct short and I did not really get zapped.  The sparks though were enough to convince me that I probably did not want to mess with wall sockets.

Unfortunately Scope Junction is no more.  As for your putting tweezers into a lamp socket, when I was about 6 years old I stuck my finger into a lamp socket at 220 VAC.  I learned a healthy respect for electricity.

Zeeglen,

 

Thanks for the information.  That is very good to know.  I will go and try and find your post.  That is the bad thing about those tools is that they are so expensive that it is hard to really know what you are getting until you get a problem.

>...looking at the Rigol DS2000...

I've heard only good things about Rigol scopes.  A 4CH 1GHz is what I wanted at my day job, but the boss found something cheaper.  Take a hint - avoid the ATTEN brand like the plague.  I wrote a 4-part blog over on Scope Junction called "The Scope from Hell" about all its shortcomings, and am still finding glitches.  Triggering becomes erratic in averaging mode, and just last week discovered that when I use inverted screen colors for pasting waveform captures into a schematic, the horizontal scale factor disappears!

From what I was reading, though, it was at times cheaper to purchase something from England and then have is shipped to Australia.  Shipping then should not be the cause, but perhaps higher cost of labor might play somewhat into that.

Well Australia is at the A** end of the world so there's some justification from transport costs.  And wages are probably a bit higher here than some other places.  But considering most stuff comes from China these days that does not explain doubling of prices like this.  As you say consumer electronics is a big one - things like phones and computer stuff often seems outrageous compared to the US.

I know that your government recently called some of the larger consumer electronics groups on the carpet to justify their pricing.  It is always hard, though, to gauge the seriousness/truthfulness of these types of things as the news can get a little twisted over such large distances.  It is always better to hear it directly from people that are there.

It took me about 6 months to find it on ebay.  The patience paid off.

@Adam, Sixscrews....I just got an email from RS yesterday with some Tektronix specials and the prices have come right down...cheapest <$1000 and some very tasty ones (MSOs) from < $2000 I think.  I have bought a couple of Lotto tickets!

BTW my current scope is a 25MHz CRT clunker.  The Analog Discovery discussed above would almost beat it...... I'd love just to have your current one!

Hi Adam:  That is awful to see that it is almost double the price of the student version here in the US.

Welcome to Australia!!  It happens a lot here, and then the retailers cry foul because everyone buys stuff on the net!    However I am happy with that price....for $7.50 extra I can get it with the TINA suite which does simulation and PCB design as well as having instrument software that works off the AD.   On the Aussie site there are only 2 price levels, commercial and academic (students and teachers).

Also, it costs the same as my NI Mydaq, which is 200 KSPS vs the AD's 105 MSPS.  Go figure....

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
