Negative Feedback T-Shirt Design Contest

[LEECH666]

So ...

... am I the only one who noticed (and is bothered by) the misaligned junction point on the circuit drawing of #19 / #34?

I tried to read the whole thread but I didn't see anyone mentioning this.

I would buy #36.

Cheers.

I notice it. I prefer my hand drawn one and will ask him to change this.

More designs are up, but still nothing that takes my fancy.
I was hoping for some magic like we got with the Amp Hour T-Shirt.

You can't get the magic that happened with The Amp Hour t-shirt. He lives in Ohio and you can't afford him.

I do not understand why to use a non-inverting aplifier. Of course the OP gives negative feedback but the feedback of the whole schematic is still positive, which I do not like at all.

There is no positive feedback in that schematic. This is positive feedback. R2, specifically.

One may want to consider the 'PC' aspect and offer an alternative.

For example, up and coming engineers may want to wear one of these around the office or company function from time to time.  If he or she expects any type of promotion in the eyes of current management and or HR types The slogan 'I only give NEGATIVE feedback' is a show stopper.

On the other hand an opamp osc with the slogan 'I only give POSITIVE feedback' may be just what tilts him or her over sharp edge with some advantage in their eyes. You may think this is ridiculous until you've spent five minutes with an HR type or sorry to say a know nothing mgr. I'm not suggesting ALL mgr's are duds but too many are to take a chance.

Dave, this could be a win win for you with TWO nice offerings.

Having spent 30 plus years in the engineering/business world with 70% in mgt I personally would have second thoughts in today's dog eat dog world wearing the NEGATIVE FB shirt around the office or at company events for fear that it could be a career killer. That said ( I really like the shirt and slogan ) on a personal level.

It would be a crime to see a talented EE either passed by or scolded by a senior 'Muggles aren't meant to get it!' as you say.

If you have a manager who's too much of a dumbass to recognize that it's a joke, I'd say that job is probably a bit of a "damned if you do, damned if you don't" situation where if you want any chance of keeping your job at all, you should probably refrain from wearing T-shirts with any sort of joke on them. The rest of us will wear the one that doesn't make us look like overly happy school counselors.

I would like #47 if the circuit was on the left and text on the right.

Yup, bang on.
Wear a suit and practice your puckering technique in the mirror every morning.

What? #34 is the current front runner? Are you kidding me? Of the 8 designs I got to vote on it was one of the ok ones but wasn't one of my top 3.

Nope, that's how polls work, you get an equal 1/N vote

my top two are the bottom two in the pack of 8 and my bottom two are the top 2, figures.

I find #34 is too elongated, looking like a laser gun

[EEVblog]

#34 is back with my hand drawn circuit, all white text, and hand drawn lines to match

[LEECH666]

That's more like it! I like the revised #34.

[EEVblog]

Yes, I agree it is now looking too elongated. If you could shorten the Vin just a little and slightly lower the Gnd point. Alternatively bring Rg over to the left a little more. Vin just looks like it sticks out a bit too much and that might waste a bit of the space under it. I'd like to see the Gnd point being the lowest part of the design.

That's getting bit fussy now 

I suppose you have to pick one winner but I think you should offer several designs for purchase. Some others are too good to abandon entirely.

Maybe, but I can only award one winner. I guess I could offer to by the design from the runner up.
I'm not fussy how many designs I offer, but with crowd souring, if you don't meet the minimum number for a design, then no one gets squat. More designs could fragment the numbers a bit? 
Will probably also offer the Flex Capacitor, err, sorry, Fluxgate Condenser shirt as-is.
Don't know about the 555 timer one? 

[PeteInTexas]

They're all garbage.  The joke is lame and played out.



(you see what I did there) 

[panzer]

Whichever one wins, I'm buying it! Provided, of course, that it is available through your Zazzle shop - I need more Xs in the size markings than what is usually available.

Cheers,
Panzer

 a postit note and a pen as graphics. The correct model pen of course

Time to vote on the final design:

Feel free to just vote only for the one you like and would maybe buy.

The alternating colours of the text in the original #34 meant you could easily read it without sticking your face in the wearers chest.

#66 has better artwork but #34 had a better colour selection.

I thought it actually made it harder to read

I was just charged $4.10 for two of my 555 timer shirts to Oz by DHL 

[Korken]

Hi Dave, where will you be able to buy these T-Shirts from?

Hi Dave, where will you be able to buy these T-Shirts from?

Hopefully in the next day or two.
I already have the 555 timer shirt up, and want to put up the Negetive Feedback one and the old fluxgate condenser one.
