About the reason behind to use the crappiest red LED's - see attachment. 30 years old soviet red LED on a single AA. I tried to build the circuit using MPSA 92 (pnp) and 13002 (npn) and it was a fail. Then I found this.

13002 isn't fast enough.

I've been an avid student of the quantum vacuum for 16 years.
Wow, what a wasted time...
...and wasted energy...

Funny to see that the Soviets didn't use Cyrillic writing on their batteries. Tried to make it look more western :)
(Batteries meant for export?)

Battery is not soviet :-DD :-DD :-DD quite opposite - american brand, indonesian made. Only a red LED with odd semiconductor that lights up with that low voltage.   
Although some things were with English writings (made in ussr) that was meant for export outside soviet union including fluorescent light bulbs (lb-40).

Not trying to attack the author here, as I am genuinely curious as to the answer to this question:

Where and how have you been studying this?

A bit offtopic but :

Does anyone know how I could make those leds pulsate (as an addition to the circuit)? It would make an interesting project for a novice electronics hobbyist like me, like a DIY bike flasher or something like that.

Thanks!

Depends on what you mean by "pulsate"?
There are a great many implementations of things like the Larson Scanner and micro-controller circuits/code that implement fade in/out.
If you want to BOTH operate a large number of LEDs from a single AA cell AND add "pulsing" functionality, that will not be a simple thing.
But if you want to use a more conventional power source (>= 3V) there are endless possibilities.

They will be pulsating, but what you want for a blinker is a lower RC time constant. Or in this case a lower LC time constant. I think you will be better off starting with a different circuit to learn this though.

Damn, i am so stupid.  :-DD
It is so obvious that the LED is a Red ... erm... i mean a Soviet...  :-DD  :-DD  :-DD

Hi everyone been very busy then i seen Dave's rant about this, i feel very scared that people believe in such crap especially after been debunked so well, I honestly feel scared in this twisted world where we live in, the other day i seen religious nuts at Bella Vista from that cult church you know the one where the head guys dad was outed and the son known all about it "Bobby huston or something like that... and now this......i am not joking i really felt worried been in the same shop as them after they finished with there Cult worship.............I could not believe how many of them there where now, I not been near that place in years then people wonder why many people like my self stay away from Sheeple oh i meant people.

Thanks Dave and everyone else for debunking another sheeple, so we can get on to some real engineering and science.

After that rant, it is clear that the only thing you need to be scared about is yourself.

Hmmm yes, it was a little close to the margin - and as if I can talk!
Don't ask a question if you aren't willing to listen to the answer.

Look at something with a 555 timer in it.
That will get you that blinking light that you want!
Easy, cheap and a quick project!

By "pulsate" I assume you mean that the individual LED changes in intensity to create a pulsing effect?

The easiest I can think of is to do this with Pulse Width Modulation via a microcontroller like an arduino. Simple circuit to create, can be powered entirely from the arduino (when only using a few LED's...) and the code is already in the built-in help library.

Like you, I've been a long time follower of Dave's youtube videos. This is my first time posting here, as I wanted to read how the whole debate went down on the message board.

It was very entertaining!


Also, Dave's video breaking down the circuit and designing his own was very interesting, thanks Dave!

I do cringe every time i see an EEVBlog "<thing> is BULLSHIT!" video in my YT feed, i think Dave gets wound up a bit too much. Makes me slightly embarrassed to be an engineer for some reason...

It makes me ashamed as an engineer that other engineers stand BULLSHIT without any problem when it's sugared enough, and cant't stand anyone debunking it with facts. Whatever the kind of language used.
No, i just feel that there is no need to 'shove it in the face' of the uneducated, rant and rave when engineers have logic and reason to back up their argument.

I can completely understand why Dave makes such videos. "Solar roadways is bullshit" obviously reaches a much wider audience on youtube than a 7.5digit multimeter teardown. I hope i am not the only one on here who would rather watch the latter and it would be a damn shame for EEVBlog to turn into a 95% condescending rant channel like Thunderf00t's.

It depends. For people feeling self inadequate, "shoving it in the face" of the uneducated / under-educated, many times themselves included, may feel therapeutic.

I suspect that's why so many "engineers" feel superior - driven internally by their inferiority syndrome.

These are not innocent uneducated beginners, quite the opposite in fact. They are people who obsessively research this stuff, are deliberately ignorant of any facts presented to them outside of what they want to hear, have a genuine unwavering delusion of biblical proportions, and they have an agenda.

True. And yet I rarely make videos like this, why do you think that is?

You really think that's going to happen? A handful of debunking videos in over 700 videos is hardly evidence of a trend.
I very famously lack tack, so you know what to expect in my rant/debunking videos, yet you still watch them and complain, why?
That's a rhetorical question BTW, if you don't like my rant videos, don't watch them.
I expect a certain percentage of people not like what I say, or the way I say, that is in fact inevitable regardless of what I do.
If you expect me to change just because you, who is 0.0005% of my audience don't like the way I say thing things, I wouldn't hold your breath.

Not everyone watching the videos is one of those obsessive wackos. The confronting tone of the videos probably only winds them up more, and scares off the genuine newbies.

This sounds like concern trolling more than anything else. I doubt Dave's tone is going to scare away anyone with a genuine interest.
