Site security

I get that symbol in the URL window that suggests this site is not secure. Does that mean some certificate has lapsed? I don't necessarily freak out about "security" as a site like this. I don't drop my credit card number in here, and I don't think I used my birthdate, etc. to set up an ac...

pic posting instructions

Man it's been a while since I posted a pic, and I can't find the simple instructions with a search at this forum. Does posting a pic require having the pic hosted at some other site like the old school photobucket? If I have a pic in my phone or computer, can I just paste it? Is there some preferred...

So, regarding power surges like replacing a battery--I'm wondering how that applies to just turning the power on and off. I mean, I doubt anyone leaves the power on a model 24/7. Even when I see lighted models at shows, there is usually a switch and a note for viewers to please turn off power after ...

Re: batteries connected in parallel

Well, there's quite a few of us who know our electronics, so ask away The irony is that I did avionics for 4 years in the military and I was part of a group of guys that would routinely get yelled at for troubleshooting to the component level because we still had a lot of components left over in th...

batteries connected in parallel

So I get that if I connect batteries in series, they will add up in voltage (two 3 volt batteries will equal 6 volts). But what about in parallel. My understanding is that they will still equal the same voltage (assuming all batteries connected are the same) but that they will have more current or p...

don't use resistors to fix mis matched power supply needs for multi color flashers, it won't work. Resistors work for devices which turn on and run constant, no changing current usages. Multi color flashers draw varying amounts of current as the colors vary in which colors are on and at what bright...

As near as I can tell, I burned that LED out. I used what I think was the appropriate amount of resistance, but it stopped working after 4-5 rounds of me messing around with it, so I chucked it. (I did of course try all kinds of connections, but it clearly didn't want to do anything else for me.) Bu...

The user-submitted reviews for the item on Radio Shack's website seem to provide a few useful descriptions of how the LED is used - along with numerous complaints about the fact that Radio Shack didn't provide that information themselves. :) It seems like kind of a gimmick to me. I mean, it can fad...

LED with three leads?

I got this LED at Radio Shack that says it's a "7-Color Blinking LED" and it sounded so cool. Now, it's got three leads, so how does this work? The part number is 276-0016, if that helps.
Thanks,
Mike Todd
