Re: Youtube video "Blinking LED with Single Transistor"
I have seen cheap (US$20 or so) component testers online, that now claim to be able to tell you what kind of device you have (e.g., cap vs. diode vs. FET vs. PNP or NPN), and can even identify which

But you might need to translate your message into Korean, so that they know what to do with it when they receive it. Some languages may be harder than others to handle.? Some of these groups (hosted

Re: current limited npn not allowing NPN to open
Because a resistor in series with a current source does not limit or change the current.? Your circuit had a current source driving a current into the NPN's Base pin, and I wrote that it is not a

Re: Organizing cables
Many years ago, I learned to form cables in a figure-8 (around my thumb and pinkie), and only then to bundle/secure/wrap them for travel. They don't unravel; they don't tangle; they don't mate with

Re: Canned oscillator definition PDF
I hope you sent the locally-translated and -checked instructions to the vendor. The value to their product is very important. Donald.

Hello Andy,When I changed current to 3V voltage source given Ib=11.723618?A Ic=2.4mA in linear state , I got by the calculation below that Rb=8.5k Why do you say is not a limiting current resistor?I

Re: Organizing cables
Yeah it does. We have a couple of those critters around here, one of which is hers and one which seems to have adopted me. I came in here earlier and sat down and she's in my lap in a flash. Right now

I really think that some companies ought to have access to a person who understands the english language like a native speaker. One email I just got features a product branded "Kroak", which doesn't

They're mating... I have a couple of briefcase-sized cases that I used to use for toolboxes when I was mostly running service calls. I'd keep my various test leads tied with those plastic ties that

Re: Organizing cables
Those are them. I have three sets, one for test cables, one for computer cables and the last for power cables. The only problem is the model you linked to has small slots for the cable (maybe

Re: Canned oscillator definition PDF
As many components are designed and manufactured overseas, by countries where English is not their primary language, it would not surprise me if things are "lost in translation".? Even the

I started looking at the Explanations in the posted file (m3_Oscillator Terms.pdf).? While as a whole they aren't bad, some of the Explanations are rather poor and some are deceptively bad. When in

The first part of this is off-topic, but I bring it back on-topic before the end. My parents had a toaster that had an "interesting" electrical characteristic. As a toaster, it worked fine, which

Re: Further to my query of a flashing LED circuit not working
They do make those, but it's fairly trivial to make a circuit that'll flash an LED.. A couple of possibilites that come to mind are a simple astable oscillator, or a 555 astable. Probably better to
