I was of two minds about starting a new thread for this; but I don't want have it get buried in another thread.. Also, the difference in circuit operation with hard mechanical switching vs soft 'conditioned' transistors has, in and of itself, both intrigued and perplexed me for a long time now.
So, I'll start by posting my previous videos that are relevant to the topic, and finish with a presentation of my latest little pet.. Of course, it could be scaled up, but I really need a drill-press before I tackle the precision that would be required
First I came across it was with the joule thief;
1 YouTube - Inquorate 24 - slayer's big joule thief
Which I found quite fascinating and odd;
2 YouTube - brighter purple flashes
And set out investigating...
3 YouTube - Inquorate 25
Here is a close-up vid of the differences in types of switch lighting the neon;
4 YouTube - Inquorate 26
So, more playing followed;
5 YouTube - purple flasher experiments #1
6 YouTube - purple flasher experiments #2
7 YouTube - purple flasher funny readings
And then had pretty much figured out how to reliably trigger the purple flash, AND how to show just how bright it was on camera;
8 YouTube - purple neon circuit without transistor
Which is when I got the idea to make the high frequency switch - don't try this particular idea at home kiddo's; it's a waste of time. Maybe. Was for me.
9 YouTube - regarding high speed mechanical switching
Then I digressed, trying to effectively push a pendulum on a veljko oscillator with an electromagnet, by using a delayed on-time circuit which involved relays switching so slowly as not to cause sparking, ie v close to pure square wave..
10 YouTube - pendulum push coil tuned up
And came across a crazy continuous version of the same effect;
11 YouTube - crazy purple flash staccato
12 YouTube - Bouncing purple flash phenomena
Which brings me to the latest installment of the purple flashing orange neon phenomena (more radiant??), with more investigations to follow - who knows, maybe this line of research will lead somewhere. If not, I'll happily take one for the team
