Happy birthday Greg.

.............................

Yes heat can be useful but electricity is even more usefull.

Last night I deviated from usual for some research on another project for the future, a "current pass pulser I will call it. Basically I want to build a solar setup that will pulse alternately from two caps that are filled by a radiant oscillator which draws power from say a 12v - 2 amp solar panel say 400 Ma for the oscillator the rest of the current which will fluctuate with the sun is passed through an inductor to the charge battery as Pure DC the 400 Ma should be easily attainable in low light.

The oscillator fills the pair of big caps, which are alternately dumped to the battery from whatever voltage is desired. I have the alternating dumper and oscillator almost worked out using only one IC chip, but I will need help to get it all together later. IT will take some trial and error aswell.

So basically when the sun comes up current will pass through the inductor, then when 12 or 13 volts is reached the oscillator will start to fill the caps and the caps will dump when the desired voltage is reached each cap is decoupled from the panel by some method when discharging ( I have a few idea's for decoupling) The cap dumping should be fairly low frequency 50% duty frequency controlled by the oscillator output.

It will take some tricky circuitry, but i think i can do it.

And I LOVE SOLAR.

Because the current would be fairly unrestricted to the battery no Power would be restricted. Alternating cap pulser ensure's no restriction to the oscillator output. A perfect setup. As long as you have a battery swapper so the batteries don't get overcharged.

Have a good one Greg Happy birthday again. I bet it is nice scenery in wyoming. I've never seen snow.

Cheers

Hi Farmhand,

I'm new to the snow myself. I'm originally from Southern California ... San Diego. When the economy washed away my brother's business and my business too, I had no where to go. A friend of mine owns a business in Wyoming ... can't really say where, and I have skills that compliment what he does ... so here I am ... else no roof over the head. I had to relocate over 1,000 miles from where I grew up. I think I like it here ... time will tell.

When I can more clearly understand what you're doing, I will assist in your circuitry ... first the Multi-Phase Controller ... I can only do one thing at a time ... focus, you know?

Yes of course first things first i'm in no hurry I just had an insightfull moment and thought I would "get it down" so I dont forget.

There's been a nasty earthquake in New Zealand, many are dead unfortunately, I had a feeling something was different about today. The poor souls.

I will have a visitor for a few days so might be busy. I know you like solar too so We have another usefull project after this one is somewhat nailed down, is is important to keep focus, thats how good idea's jump into heads by thinking on things.

I wonder how many people in NZ will be out of usable power now, still place's in Queensland with no power. The old systems are not up to the population levels we have now. We all need to ba able to harness our own power from the stuff we can find in the rubble. Easy ways with only a few common componants, or a TPU in a strong box.

To get a 555 below 50% duty cycle you need to add a diode somewhere I think. It's been a while.

I think the "heater" circuit is interesting, I plan on attempting a replication some day.

Farmhand, can you post your solar circuit idea? I'm interested.

I'm going to be taking a break for a while. I seem to have fried my clock chip this time, so while the metal oxide varistor around the driver did a good job of protecting that, I guess I needed a smaller one around the clock chip. Or, there could just be a loose wire or a short somewhere. The behavior is strange -- the clock works fine when I have just the scope hooked up to it but as soon as I hook something up to it to drive, it goes all wonky and slow. I decided I should give it a rest for a while and come back to it later with a fresh mind. Have some stuff to take care of around here.

Hi Guys, I think I have seen a drawing for a 555 circuit with pulse width adjustment. I think stans 555 circuit has it.

I remember when I was first building the 4001 circuit I pulsed it several time's with a coil and no recovery, by accident. It seems that the damage can sometimes be instant.

I'll have to make a sketch to explain the solar idea better, it's all in my head still and there are details to work out. But i'll make a block diagram and explaination. This is a different arrangement to the solar setup I made a thread about, much more advanced. Should be no problem to connect to up to quite hi amp panel. I'll need to buy some 200- 400volt caps they are quite expensive.

Will post a sketch when I get a chance to do one.

Do you guys have cellers or bunkers built into where you live ? Hardly anyone here has a bunker, I think I need to build one before next summer. There is the chance of serious storms and all sorts of chaos on the way I think. Below ground level may be the only safe-ish place. Not in an earthquake though.

Sigh.... exciting times but precarious living. I'll try not to leave much too chance.

Cheers

Ok i've discovered that putting a choke on the input to the circuit causes problems, it makes spikes ! With an input choke and a recovery choke my neon fire's on recovery disconnection. but with no input choke just the recovery choke it doesn't happen. If I didn't have a neon I would have either fried the chip or exploded a capacitor because of the high voltage spikes going into the circuit. OMG I'm surrounded by spike's I can't get away from them Hahahaha.

Now I can see why this setup of Nikola's would be so effective.

Looks like the amplification might start in the chokes, of course this particular setup is designed for AC supply. I think. Hense the two choke's and the switch in the middle of the primary. Tesla really didn't think about much else did he, totally addicted to radiant ! Should make a song about that.

This is the song i would like to sing to Radiant energy.

Hi Farmhand,

So now You too are seeing 'Spikes' all around you. You're not alone. Wait until we fire up the Multi-Phase rig ... " ... there be Spikes here!" ... isn't that how Scottie from (the original) 'Star Trek' would say it?

Farmhand, thanks for keep trying the freq. Although I don't know what to see on your latest scope shot.

I think it depend on perception. I wouldn't call that as choke. I consider any coil between battery and switching transistor as part of radiant spike generation. Or I understand you wrong?

Gents,

Check out the paper by Lee (smw1998a) in this thread:
The OTG Pulse Generator Paper

and the paper itself is at this link:
http://rapidshare.com/files/35989044...ircuit_PDR.pdf

He describes the variable frequency oscillator with independently-controlled duty cycle (well below 50%) in the paper.

Hi jacek,

At this point, we have all been able to drop below the sub-1% and fractional % levels. It's very simple to achieve .3-.1% now with both 'real' oscillator clocks and PWM's designed around Op Amps ... but now that our multi-phase circuit is almost complete, the concept of PWM is now meaningless. It has been reconsidered in terms of 'pulse width' ONLY, because now we have variable length spaces sprinkled here and there. We now say we want a "1usec pulse" for instance ... and we really don't care what the duty cycle is anymore ... that's old thinking ... as far as this self-charging project goes.

Hey ... but thanks for your interest. I had trouble at the download site you linked us to. I have way too many 'free' (data mining) accounts now. If you could offer a different link, that would be great.

Thanks

OTG Pulse Generator

Hi Jacek, I actually have one of those for triggering my SSG it works very well. I built it last year. So I know it works. The pulse width is fixed very narrow. Not sure of the frequency range it can work at. Mine works from 50 Hz to 350 Hz or so but I use a pot with a different value. But it is a very good circuit and is very usefull for running my SSG without the rotor, which is how I must use it for a while because my wheel bearings are kaput.

Using the pulse generator while the Rotor is not needed save's quite a bit of power. I power mine from a 9v transitor battery.

Thanks for the reminder maybe it can be modified for a variable pulse width PWM for other purposes, though like the rosemary Ainsley circuit, which I think is what you mean for it.

Good thinking and good find.

Cheers

high res.

Hi all,

OK ... tested 12-bit today. ... there be range now here ... woopdee doo!

I'm still here, good work, my visitor is gone but i'm bogged down with work so I still havn't cut up the transformer laminate yet. I'm not even sure if it will be any good for the purpose, I do have another piece but I can't find it. Now i've lost a DMM, I can't find it. .So I tried different probe's on the one I thought was fried, and it works, the positive probe was broken. Phew.

First time i've lost a whole DMM it's a big one too and orange. Unbelievable.

Anyway top stuff, don't work too hard.

Prototype 12-bit Poly-Phase Pulse Module

Hi all,

My eyes, fingers and brain are fried. Here's a .jpg of a prototype 12-bit Poly-Phase Module. Two of these are used in a 3-Phase setup. Or three are used if you want to fire off all three phases simultaneously in a 3-Phase setup. It's complicated to explain why ... has to do with the steering logic that makes the whole thing work. All those resistors (2K) are current limiters ... not pull-up, pull-down or bias resistors. The blue dip switches are SPDT switches I'm using for the program logic. This method of delivering a logic '1' or a logic '0' eliminates huge circuit power overhead otherwise present when using dip switches with pull-up/pull-down or bias resistors. When you have as many bits as these (12) it adds up to real 'power' consumption, and there's no reason for it. I wanted to share this with those of you who might be fiddling with digital. The switch actuators are nicely 'raised' and 'big', plus you can flip them with your finger instead of a ballpoint pen or a needle ... and the contacts are gold-plated.

http://02d1852.netsolhost.com/radian...lus_driver.jpg

This module places a gate-driving pulse at any one of 4096 locations within a determined pulse period. This is based on a 1usec Pulse Width and a 500KHz clock frequency. At the far right is the UCC27322 gate signal process driver. It's not tied to the output yet.

Good night

'nother teaser

Hi all,

Couldn't leave well enough alone. Operational frequencies of 125Hz to 500,000Hz. Here's one more picture:

Stop teasing me Greg or I will magnify the photo and patent it. Just kidding. Looks like a good thing to me. I am prepared for eye strain for a good cause. I thought you were going to take a break and slow down a bit ! I'm still kinda layed up a bit. I have a pool of money put aside enough to buy all the parts several time's over, hope you don't mind if I build several controllers. As soon as you give the go ahead I can have a buy up and go hard, i'll have an area cleared away for running and testing long term, i'm just going to go ahead and order the core for the choke, i'll compare the data on it to some other's and depending on price i'll get some similar but different one's for test's. I think I will try to get some more silver coated wire too. I have money to get the PCB's done also,


Cheers
