Good start Chris. This wasn’t endearing to me, but had he asked properly, I would have been glad to answer instead of ask him a higher question, one I was sure he hadn’t ever thought of. The SCR latches with very little effort, DC in one way will turn on the SCR, the reverse to the gate cancels...

1. A minor or unspecified object or article.
2. A set of light, open shelves for ornaments.


I'd never heard of the second definition.

2. A set of light, open shelves for ornaments......[second definition].....as in ...For Bric a Brac.

Stuff. Informal.

Obviously Im still not taking any slander from you.

But at least I don’t whine.

Your post is not just about its header statement?...... If on and off were your only issue when you plug in the wall wart, a simple relay or SCR/ Triac will do that job. As to tapping off the main supply to make two other voltages, yes you can do that as well. You can also add in diodes or the resis...

Here is a simple exercise, which Newton’s law did this apply to, “for every action, there is an equal and opposite reactionâ€

Did any one mention banning Ignorance?

Seems to me the loudest controversial posts here that don’t stop, come from the “you cant do it crowdâ€

Your problem is in the gate section. Much like a transistor gate, the middle of the tube needs a jolt. [voltage] Usually around 400 volts, sends the tube into conduction of 4kv. [Flash] Yours seems to keeps the gate open and supplying some form of current to cause a discharge, most likely the SCR th...

There are a lot of magnetic materials out there, Al-Nico being one of the oldest.


Aluminum and nickel.

You might prefer the P-channel FET solution. A SCR needs a certain minimum current to remain latched, which could be higher than the load current. Also, the voltage drop across the SCR is higher than a diode, probably in the 1 to 2 volt range, and may be unacceptable with a battery supply. 5 ma hol...

As usual, you try so hard to recover your lost body parts, your responses are just a joke. I have many books on many subjects, even ones written for you, like Radio Shack. When dealing with the ignorant or those who refuse to learn, you always keep your options open. Mimms, a laureate, a scholar, a ...

Im like you, last week they mentioned all sorts of things, but no actual times? Just the date of Tuesday. [Three pages of nothing] Also they mentioned two weeks ago about the meteor shower, but that was a dud. Only Three good rocks? Im sure If you were watching things every day, some where they said...

Seen one clique you have talked to them all. I just address Philba and I know your right there, one in the same. And you act like I only addressed one person, actually it was two but that didn’t include the talking clique. And with out going back and looking Im sure you tried to ask me a question ...

As I said, I already answered mine, more than once. Here is some light reading for you.... The efficiency of thin-film Si cells is even poorer than for wafer-thick Si cells. How to make the cells cheap (using thin films) but also nicely absorptive is an important goal. Scientists at the University o...
