Broken Swiss Army knife

The swiss Army knife that I got for HP in Colorado Springs in 1994 finally broke the the point where it's unsafe in my pocket. So, I replaced it another freebee, but it's a knockoff. The blades are too dull to be useful. I'll try sharpening the knife blade, the the scissors are rather difficult.

I may actually break down and buy a real Victorinox. The knockoffs (I have two) are junk).

Too right.  I had a nice Victorinox but I forgot to pack it  in my checked baggage and they took it off me at Johannesburg airport some years ago.  As you'd imagine, I was pretty bitter.....

I would have lost my Victorinox knife at the Statue of Liberty, but I ran it back to the car before going on the boat.

I hate it when that happens -- I've lost more knives that way -- also when I went down to the courthouse, I forgot I had a knife on my belt -- them made me hide it in the bushes outside before letting me in the building

As they say, you get what you pay for (like my super-duper American-made Saddleback Leather Wallet vs your cheap and cheerful Italian knock-off)

I visited a clock factory that was next door to the Wenger Factory in Dalémont.  We got the little pocket versions as souvenirs.  It was a really nice knife and I liked it a lot.  When my purse was stolen, that was the item I missed the most. Even after 13 years I still miss it.  The tip of the nail file was also a bottle opener, which I would have never known otherwise.

It is hard to find the Wenger knifes outside Switzerland.  I did locate one I liked, but due to security rules I do not carry it with me anymore.

There seems to be some controversy over what is actually the originator of the design.Victorinox_and_Wenger

I do know that the watchmakers I met prefered Wenger.  The Tool suppliers in St Criox seem to have attachments for that brand.

Victorinox, at least in the 1990s was more of an export line. Given the number of places that sell Victorinox I doubt most of them are made in Confederation Helvetica. The wiki page implies that German factories are the principle subcontractor.

As an editor, we get little trinkets like that from time to time. Not so much anymore except for USB flash drives with press materials on them. I have more flash drives than I know what to do with.

Two Swiss-Army knife test instruments have come along recently. ther first was theTek MDO3000, which has everything but a power supply. This week, we have the NI VirtualBench. It loses the built-in screen but adds the power supply.

Why the Swiss Army Knife?

It looks like a nice little IC for what it is -- a configurable data converter. Why call it a Swiss Army knife, when it's not trying to be one?

Well, it's one of those chips that can do so many different things in so many different applications -- a bit like a Swiss Army Knife with one of those special attachments for extracting boy scouts from horses' hooves

Anti-aliasing filter?

I saw this chip just the other day and was super excited about it. I even have an application in development where I could use it, but the MAX11300 has one major hole: Where is the anti-aliasing filter? If I have to implement it myself external to the chip, then there is no point in making the ports configurable, because I have just locked down the ADC channels.

Thsi topic did come up while I was being briefed on this little beauty -- but rather than me put words into Maxim's (metaphorical) mouth, I'll ask the folks at Maxim to respond ... watch this space.

Simple RC anti-aliasing on the ADC channels may be all that is needed in many cases.  It's true if the system is reconfigurd 'on-the-fly' then the user would eed to know where the ADC input channels are if they are deploying anti aliasing filters.  You could get creative with the internal switch to enable 'R-C' filtering on an as needed basis...ut this may not be the best use of Pixi pins.  product details and datasheet can be found here....http://www.maximintegrated.com/en/products/analog/data-converters/analog-to-digital-converters/MAX11300.html

Probably not the Swiss Army knife of anything but its adoption in the market will depend on price which I haven't seen yet.

It can do a lot of things but does it really have enough advantages to go with a single source, proprietary solution? This depends on the application.

Everything is a ballancing act -- but Maxim is not a "fly-by-night" company -- you know they are going to be around for a long time.

There are two major advantages to this part:

a) It dramatically reduces BOM cost* and saves board real estate as compared to using a bunch of other devices.

b) It's programmable, which allows you to make "tweaks" to future-proof your system.

*I know, I know, you want to know how much they cost -- see my next comment

Don't you mean inputs?

In the paragraph:

In the case of ports configured as analog outputs, any adjacent pair of ports can be used to form a differential ADC. Furthermore, any port of such a differential ADC can be internally biased to form a pseudo-differential ADC. (Multiple ADCs can share a common bias point.)

don't you mean ports configured as analog inputs, not outputs?



(Kind of hard to make an ADC with an analog output.)

I agree -- a picture says 1,000 words, and a video says 1,000,000+ -- the trick is to persuade folks to make them ... I always ask, but oftentimes they are short of resources (like the rest of us LOL)
