I make things too hard… Thanks Lee…
Nothing is quite so humbling as someone coming in and showing you that you are making your problem way more complicated than it really is. Lee pointed out that I was overthinking it: that a simple 2N2222 would work just fine, and indeed, I went back over it, and realized he was right. I entered in the schematic shown below into LTSpice….
And it looks like it will work fine. I had thought that the 2N2222 would have to dissipate too much power, but I made mistakes based upon two problems: I had placed the current limiting resistor on the emitter side of the circuit, which meant that the base of the transistor was improperly biased, and I had originally used a 12v supply. In the configuration above, less than 50mw gets dissipated by 2n2222, and just about 1/2w by each of the current limiting resistor and the LED. Cool.
And thanks Lee, for taking the time out of your day to lend advice to such an introductory topic.
I suspect the world would be better if that percentage were even greater.
Apparently 15% of all web traffic is cat related. There's no reason for Brainwagon be any different.
Thanks Mal! I'm trying to reclaim the time that I was using doom scrolling and writing pointless political diatribes on…
Brainwagons back! I can't help you with a job, not least because I'm on the other side of our little…
Congrats, glad to hear all is well.
