Agentgates´s TPU setup with strange wavehill hump

[hartiberlin]

Hi Magscave,
please try to use 2 Reed switches in series.
This will make faster current cutoffs, dI/dt will be faster and give you more induction kickback voltage.
ALso it will save a few Reed Switches.

Good luck.

Regards, Stefan.

Movies,

I love the movies!!
I heard there was a good mystery playing here tonight.

But this one looks like a THRILLER!

Hope he doesn't burn the film with that bright light!!


Are they gonna give us sunglasses??

Ok well I did a vid, and it shows that the led is very bright on the secondary. But I need to go mosfet and 555 from here. I need to have consistancy. The way the reeds are sticking and firing kind of erratically, the demonstration is broken up. The new reed in the relay, I changed them both, isnt working the same as the other. I used a bigger activator mag there and when the relay coil reed is latched, the led on the seondary is lit from the bemf being stored into the cap, but as I take the mag away she fires that led up.  But I want to do this thing better with some fets.

New coil demo   it isnt processed yet so may not be clear at first  just loaded.

This is an led burning up on oscillator bemf, just did it and was surprised how long it burned.  boring but I caught clear vid inside the led.  My camera, I have to pre focus then record, so thats why it is dull till we see in the led.

I will try that Stefan Thanks.   I think that the duty cycle needs to be more than what Im producing.  Cant tell till I get a scope. But saving the reeds would be a good thing.  =]   SRF   Save the reed foundation

Hi wings and all,

summary: I found that the kind/brand of switching device I use has a big influence on the output. It is probably a good idea to try different ones. I think they "resonate differently". Thus the light output on the secondary is different for each one.

details:
From my square wave generator I go straight into the switching device and then straight into the primary. I tried three different switches (haven't got any other ones):
IRF540N
2N3055
BU508D (out of an old TV)
Each one gives a different result. For me the BU508D works best.

I power them from a 12 V car battery and use a 21W car light bulb as a load in series with the primary coil.

My signals look just like the ones wings posted here

Top trace is primary, lower trace is secondary, isn't it?

On the secondary I can light leds and make small filament lightbulbs glow. In my setup this happens between 1 kHz and 5 kHz. At the critical frequencies the input current goes down and the lightbulb in the primary circuit gets dim/extinguished.

....made it from a Toilet Paper  roll so i call it a TP Unit  .

Hi Mk1,

I wound it on sewage pipes, so I consider the SPU my intellectual property, and should you ever infringe on it, your lawyers will hear from mine.

The depicted setup is as described in my previous post.

The light bulb is lit across the "speaker cord secondary" which is located in the ring.
Got the idea from FatBird, but ended up connecting the two strands of the cord in parallel, so it is not bifilar, as per his recommendations. Gives me better results that way.
But need to experiment further.

The leds are lit from the end of the original secondary. That original secondary is wound 'agentgates style' and the leds are attached only to one end of that secondary via an AV plug (Avramenko plug). This AV plug is grounded.
The other end of the 'agentgates secondary' is free, i.e. not connected to anything.

The signal on the scope is from the 'speaker cord secondary' with probe across the filament bulb, 5 V per div.
