The cloud of unknowing

Is the cloud disruptive?

Here's a cloud website that I consider to have tremendous disruptive potential as technology:

Datasheet Zone & DrawSCH : One stop to find datasheet,IC pinouts and application circuits & Draw schematics online for free!!!

Its potential for being disruptive innovation is so far untapped because I can discern no marketing strategy as yet. I've written to the founder and suggested having a dialogue about all the possibilities presented here. If I get a response, then I'll write more in a later post.

... as the saying goes, everything starts to look like a nail. That's what's happened to me now I've started to look at business through the eyes of disruptive innovation. Its all around, everywhere I look I'm seeing signs of what I call 'disruptive stress'. Perhaps just 'disstress' would be the right term for it - businesses are disstressed.

Nokia is one big business, but its quite clear they are disstressed, big-time. Their 'cooperation' with Microsoft can only lead to one thing - being embraced and swallowed whole and digested as Boa Constrictors are wont to do. Wikipedia says of the Boa :

The size of the prey item will increase as they get older and larger.

OK Nokia's not of great interest to audio guys, so how about one a little closer to home? This morning in my inbox I received the regular missive from EETimes, replete with the latest gossip from the semiconductors world. Topping the bill - Freescale, with its monstrous debt pile. They...

About 6 watts

Posted 25th June 2011 at 03:38 PM by Pano

The other day I was wondering just how much power I really need for my rig. Can't be much as I run Altec A5s in a small room - but how much? Would a 10 Watt SE amp be enough?

So I set out to figure out how much power I need.

A few weeks back while doing some crossover work and measuring voltages I was surprised to find that my horns are running about 5mW of power - average. Uhhh, that's not much. OK, but what about the woofers? Here is how I proceeded:
  1. I found a few bass heavy tracks and played them as loud as I would ever care to.
  2. The average volume knob setting for these was noted.
  3. The tracks were opened in GoldWave and low pass filtered at 440Hz, same as the woofer section.
  4. The low passed tracks were analyzed in GoldWave for their RMS value. Average was -15.5dBFS RMS
  5. Using the function generator in GoldWave I made a 40-880Hz, 30 second sweep at -15.5dBFS.
  6. This sweep was played back several times at the same volume setting as before.
  7. Voltage

The historical roots of disruptive innovation

I've been chasing back a little of the history of CMC's idea which I expounded on in the last post. There's nothing new under the sun of course so I'm sharing here some of the writing of Joseph A Schumpeter as I find it pretty inspiring.

I first learned about Schumpeter from reading a book on management compiled from the extensive writings of Peter F. Drucker ('The Essential Drucker'). In one chapter Drucker sounds very much like he's reading from his crystal ball and predicts that where Keynes' ideas ruled the 20th century in economics, it would be Schumpeter's theories that reached ascendancy in the 21st. Having read some of Schumpeter based on that recommendation I'd say that Drucker was indeed spot on.

Here's a short taste of what Schumpeter has to say -

The first thing to go is the traditional conception of the modus operandi of competition. Economists are at long last emerging from the stage in which price competition was all they

Disruptive technology or disruptive innovation - what's the difference?

Posted 19th June 2011 at 08:12 AM by abraxalito
Updated 8th September 2011 at 03:11 AM by abraxalito (Added link to CMC's own webpage)

This week Bruno Putzeys posted about his innovator's dilemma. You can read that post here:

http://www.diyaudio.com/forums/class...ml#post2608169

In brief he's designed and produced some disruptive technology (UcD, and now nCore) and can't quite see the way forward to turning that technology into disruptive innovation. Disruptive technology is not automatically disruptive innovation - it needs a suitable marketing strategy before its truly innovation. Bruno's using the traditional marketing plans for OEM amplifier modules and finding he's not making much headway.

'No one puts new wine into old wineskins, if it is the skins burst and the wine is spilled and the skins are destroyed; but new wine is put into fresh wineskins and so both are preserved'. - Matthew 9:17

Jesus might just as well have been lecturing at Harvard Business School here because this is precisely the message of Clayton Christensen's book...

Parafeed output amplifier circuits

Posted 17th June 2011 at 01:36 AM by tubem

Has anyone in the forum built a parafeed output amplifier, could you please tell me about your experience with it.Do they sound any better than a typical single ended design? Thanks tubem.

Companies don't seem to get it

YouTube - EEVblog #178 - Agilent U1272A Response

Now - out of all the companies Dave mentions, which one is toast? Hint - its a famous name in handheld test and measurement beginning with F and sounds like 'puke'.
