I doubt it, I'll have to check with legal on that!

I think any story, compelling enough, has a chance to win as long as it involves a repair/redesign.

Hi Glen.  Hope you're well.

> "Did you read 'Glide Path'?"

No, but you've shaken me out of my lethargy and I just ordered one on Ebay ($4).  If it's ACC I'm sure I'll enjoy it.  Look forward to seeing a story from you for the comp!

PS Q: Why don't sharks eat lawyers?   A: Professional courtesy!!

Hi David, nice to hear from you again.  I finally read ACC's "Death of the Senator" on my wife's Kindle, good story. Thanks for the tip. Did you read 'Glide Path'?

Discriminate?  This is the result of lawyers, damn lawyers, and damn^2 lawyers!

(PS had to check the spelling of 'lawyer'.  Seems to rhyme with 'liar'...)

@ZeeGlen - "...the Tek scope contest is probably limited to a single entry..."

It is indeed - why would they do that when there are so many good stories to be got out of someone like yourself?  At least you're allowed to enter - they discriminate against Aussies....:-)

Done this many times with various Heathkits (I was once a Heathkit tech, long ago) and industrial electronics, here is my favourite:

Heathkit HR-1680 - a low-cost but reasonably high-performing ham-band radio receiver.  With the audio CW filter on it could pick 0.1 uV signals out of the mud.  Not quite the same class as the SB-series, but damn! it worked good. Sometimes the front end would oscillate if the RF gain turned up too high, easily cured with a resistor in series with the wiper hot end of the RF gain control.

Its main problem that many Heath customers complained to me about was that all signals were S9.  The S-meter tended to hang in the middle, only very weak or very strong signals pushed the needle below or above S9.  I studied the circuit and came up with a modification to make the S-meter behave properly, actually truthfully indicating the relative incoming signal level. My Customers were happy.

Heathkit Engineering approved my change, to be applied whenever a customer complained about this defect.

Could relate many more stories, but the Tek scope contest is probably limited to a single entry.  Besides, would not want to get started on the SW-717 or the CO-2500!

Hey, Caleb!  in the yada-yada on page 2 is

This Contest is offered and open only to legal residents of the United States of America

What have you got against us Aussies and other infidels?   How about if I promise to come and collect the scope in the US if I win (I reckon it would then work aout about half price.....  :-)   If not, you'll miss out on at least 2 stories..... (and I won't re-enter the fixes I did for Max :-)

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
