View Full Version : The time is 10:23 and 47 ohms
Surfing around today I stumbled on this interesting product. It's a wrist watch that has Ohms law and other formulas on it. I found it very interesting and thought I would share it with the ham community. Check them out. Ohms Law Watch (http://www.technotetime.com/TechNotes.html)

Very cool, but probably not the thing to wear to your test session.
Sorry, wearing my VE hat here.
Now, if they'd make one in a 24 hour format...

DARN!!!
And I was going to get one to use for my Extra Class exam (I'm having all kinds of no-fun trying to learn formulas #http://www.qrz.com/iB_html/non-cgi/emoticons/sad.gif )
(just kidding!! #http://www.qrz.com/iB_html/non-cgi/emoticons/laugh.gif )

Excellent. That is a neat idea for us electronic folks out there.
And even better since Christmas is just around the bend, and I have been going nuts trying to figure out what to buy my dad. He is an electrician and a retired electronics tech from the USAF SAC. He would probably get a good laugh out it and actually use it, since he has had problems lately forgetting the color codes. He is always calling me wanting his memory refreshed, and this watch would solve the problem.
Just thought I'd throw something in.

It's a perfect stocking stuffer for those who have use for it.

You need extra special eye sight to read that color font

Gee, let's see now, lunch is a Boundary Condition between apparent power and total current?
How about breakfast and dinner, anyone?
Why didn't they come up with a Polar coordinate watch?
Or, better yet, with a complex rectangular face, with #real and imaginary values and magnitude and angle as well, as the vector rotates?
That way, students could just adjust it to the R and X values, and see what the magnitude and angle of the Impedance vector are.

What about the ones that have NOTHING? - give it one of them. http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif
Maybe a good gift for an electrician or technician, but an engineer or a professor? Come on. Not worth their "salt" if they can't derive them all in their heads in 5 seconds (how many Ohms?) or less...
That's a nice-looking watch. #However, I like the one I have much better, which is an onHand PC watch. #It's a wrist PDA, that has its own operating system, 2 megs of memory, and, if you know C, you can write your own watch applications.
Here's a couple of links:
http://www.matsucomusa.com/
http://www.pconhand.com/
Besides the usual time and stopwatch functions, you can also keep all of your appointments on it, and download your calendar from Outlook, if you want to do it that way.
You can store text files on it, too, which allows you to carry all of your electronic formulas with you, and a to-do list, and shopping list, and a..... whatever.
I set up a special version of its address book, that I use to maintain information about every IRLP node! #I can quickly look up a node number by country and city.
Plus, I have a special program that allows me to practice Morse code, if I have nothing else to do.
This watch is so cool, and there are LOTS of utilities, games, graphics, music, and other programs available for free download.

My Casio will do 24 hour format, and with push of the button displays GMT. Also sets itself to WWVB once a day.

Push a button and it plays "Ohm on the range".
I really like the desk clock:

OK, how cool is that?!?!?
"Dick Tracy, calling Dick Tracy!"
Is there an HF/VHF/UHF version? http://www.qrz.com/iB_html/non-cgi/emoticons/laugh.gif Why not? Cell phones can access the internet. CW on your watch?
SSTV via wrist watch? I do believe the list could be endless.

Thanks for the info on the watch. It sounds like just the thing for me to wear.

I won't buy this one, but if they had a model with Smith chart on its face...One could just turn hands to see the impedance down the antenna feedline.

Wow, what a surprise to find our website being talked about here! Thanks to n9bc for posting our photo, and a bit of news. The Ham community is wonderful to us...My friend at southgatearc.org gave us a big boost with the ham radio crowd when we opened up "shop" a few months ago.
I would like to mention that we carry both AC and DC versions of our product. The DC being more electronic oriented, low voltage, basic theory that sort of thing...The AC being more engineer level.
I'd like to offer QRZ members a 15% discount off our advertised pre-Christmas sale prices - on all our products! Please enter at checkout the following coupon code: QRZ
International customers may contact me with their order so I can compute better shipping rates, in most cases $4 - 9 for 4-7 day shipping! Thanks again and please visit us when you get the chance -- my family and I would appreciate your business! Anne Dorsey

Way back in the days of my youth, I had an electronics teacher who said "a good engineer doesn't know all the formulas, but he knows where to find them."
Granted, Ohm's law is one we shouldn't be forgetting, but truthfully, I have a colour code chart here as I've finally gone long enough without using the colour codes to not always have them up front. Sometimes I need a gentle reminder.
I have to say though, I think the watches and clocks are a cute gift idea. But for me, I think I'll keep my radio room clock with the silent periods and autoalarm timing marks on it.
When I went to get a job in the electronics industry, a friend gave me a mnemonic to remember the resistor/capacitor color code:
(it is perhaps not quite politically correct, but I have remembered it for 25 years now!)
Bad boys rape our young girls but Violet goes willingly for gold, silver,
or nothing at all!
Bad - Black
Boys - Brown
Rape - Red
Our - Orange
Young - Yellow
Girls - Green
But - Blue
Violet - Violet
Goes - Gray
Willingly - White
for Gold - Gold
Silver - Silver
or Nothing at all - Blank
It came in handy when I took and passed the Communications Technician test for AT&T, and when I took my General, Advanced, and Extra exams.
BTW - what I did when taking these tests was to write the formulas down right away on the scratch paper provided at the beginning of the exam so I would have them at hand when the questions came up.
Hopes this helps someone.
