Missing the point

[envisionelec]

The photos I posted are of ideas for a design, not an actual one. I get a kick out of the responses that assume a pretty rendering equates a finished product. Some of you guys are getting in far too deep with worries about airflow and fan noise, thermal considerations and a clear plastic cover.

With the tools of rendering, any idea that comes to mind can be presented and, eventually, achieved. But that doesn't mean it is a concrete idea, or even based in reality.

I guess I take my experience for granted around here. Most of the people posting these days have been on this board for a short time and have no idea what I've built in the past or what kind of experience I have in design. Oh, you can speculate that a guy without a $75K piece of paper that claims EE status would have "no idea what he's doing". Of course I value higher education and have a college degree, just not the one you think is necessary to build a working, reliable amplifier. Funny how I interact with EE's all day, every day, and most believe I have that expensive piece of parchment hanging in my living room. I design test equipment and procedures - the equipment that tests what the engineers have built. Some would say that it requires a fundamental understanding of electronics to grasp the measurement process. Others will just keep looking for that framed thing and discard all the silly notions of a floor sweeping technician. Hey, I agree that most techs are as bright as dirt clods, have poor social skills and couldn't drum up enough motivation to roll themselves out of a paper bag.

Don't get me wrong, the choice of not having the usual EE degree is not one I made willingly, but a chance of fate. I am mildly interested in working towards a degree, but believe that the only gain would be a slight financial one. Oh, and a potentially inflated ego. That is something I do NOT need. :)

So, you may ask, why do I continue to build this side business up? What is my motivation? I have an entrepreneurial spirit that is willing to take risks. I enjoy it, and, if I'm not taking a risk - I'm not learning anything. Being a firm believer in learning by screwing up, I spend a lot of time investing into the possibilities of a good outcome. And I have become quite good at this. Eventually, these little bits of learning will become a very valuable, very profitable adventure. So, it's small potatoes now - who cares? I'm having a lot of fun doing it!

So, quit missing the point. Thanks. :)

I didn't see the terminals for plugging in the welder...

I saw nothing wrong with the renderings. They look well-planned to me.

LOL! Yes- I agree that you don't need the fancy piece of paper. It's the brains at work, not the evidence of the brains.

You said it, I didn't!

That is indeed the point.

Later, and keep it up! How's the PCB's coming? Just asking,

I didn't miss it. :)

btw, got the stuff, PE is packing stuff much better these days

nice amp layout... :)

You are not alone. Applied economists get no respect on this board either. :-)

Gee, NOW I feel better. :~

What company do you work for? I just applied for a test engineering job...

GREAT post, Aaron!

If it ain't cheap, it ain't fun :-)

Aaron,
Could you post a link to your commercial website? Thought I had it bookmarked, can't find it though...

BTW, I'm not asking just so I can pick apart and criticize your designs :)

If you're looking for different electronic things to market, I've been looking for an active subwoofer crossover (line level, perhaps variable or offer 3 or 4 different xover freqs, maybe variable slope, both high and low pass, perhaps a rumble filter). I think it would be awesome to be able to crossover to a sub at 80hz without using the crappy things in a plate amp or relying on the mono LFE of your HT receiver, or introducing massive inductors/capacitors in a passive design.

Best,
Sam

Sorry if I came off as pushy, Aaron.

I'll be interested in watching the rest of the project unfold, and hopefully buying the first one off the block!

:)

Thanks, Sam. The site is <A HREF="http://www.ezamps.com">www.ezamps.com</A> where I currently sell the PointZero Amplifier. Although it is currently the only item for sale, I am working on others, including a subwoofer crossover like you pointed out.

Oh, and to the other guy - I work for Kodak's Inkjet Printing division. Not desktop printers, but commercial, 1000'/minute jobs. Talk about data throughput. :)
