Good stuff

Nice thread. I love it when people make useful projects

Image attachment

Ok fixed the links above. I'm not as computer savvy as I would like to be I can't work out how to make it so the thumbnail attachments open up big. Any hints on how to do that ? I won't change any attachments till I work that out.

Any way I have a lot of links to fix now, how embarrasing. I'll do the best i can as quickly as I can.

Sorry folks monumental mess here, it seems my computer is just as messy as my work bench.

If anyone wants a drawing linked or fixed just let me know.

Regards

Hi farmhand
imageshack and yahoo flkr they are all great link tools

e too i want to start on your voltage swapper ad auto oltage regulator from solar panel

thanks

Hi all, very sorry about that, accidentally removed wrong pictures from my space, will upload them again as soon as possible. My mistake just another funny error on my part. Very busy today probably about 4 to 5 hours.

I don't know how I went wrong, they are upgrading windows live blogs to something else and I was attempting to move my pics to a different location, but i ran out of time. I'll fix the links above and all as soon as I can.

Once again very sorry about that. I'll fix it.

Cheers all.

Circuits

Hello all,
I've been messing around for a while with a very simple circuit to pulse a battery from a solar panel and make some better use of low light days (cloudy).

Here is the basic circuit.
http://7iprpq.bay.livefilestore.com/...c-2.bmp?psid=1

The SCR capacitor arrangement allows the solar panel to keep the capacitors a couple of volts over the battery even in continuous conduction mode when the SCR does not switch off, in low light when the caps fill very slowly the SCR switches off and on and the circuit pulses the battery with amplified power up to 5 or 6 X, eg with 50Ma from the panels this setup pulses out up to 300Ma.

It's quite simple and works pretty good I have this basic setup boxed up so I can use it as a portable charger with a small solar panel.

I have played around with ways to force the SCR to commutate (switch off and on) and came up with the idea of adding an trifiler oscillator with capacitor discharger to the output of the original circuit which works very well and also allows the oscillator output to used alone.

Here is the final circuit that i'm using now minus the led I havn't tried that yet.


The oscillator source battery can be recharged from the panels, the capacitor dump voltage can be adjusted by the zener selection, the oscillator has frequency/power control, the SCR cap dump on the charge side of the oscillator has not been tested yet because I use a cheapo charge controller there but I think it will pulse charge the oscillator source battery as well when the oscillator is running.

The setup is self regulating to a degree in that when the oscillator is running and the setup is pulsing, the battery will stop charging at the desired voltage if the correct zener is selected eg. if the panels can only put out 20 volts max and the voltage drop caused by the zener the 1N5408 diode and the SCR gate trigger voltage equals or exceeds the difference between the battery voltage and the panel output voltage the panels can't raise the cap voltage high enough to dump so the solar power is blocked and the battery is trickle charged by the oscillator. This feature can also be used to equalise a bank by selecting a lower value zener.

I also made a battery swapper with load dump to go with it, it still has a bug so I have not labeled the zener value's and relay working voltage ratings yet.
It works ok but the zeners get warm so power is leaking where it shouldn't.

Here's some video's they are not good I will make a better one later.

Any idea's too improve or vary this circuit or add to it are welcome. The oscillator I use is a variant of John Bedini's design the SCR cap dump is old hat. I think that covers it so far.

Edit. I should add that the capacitors in the basic circuit could be any suitable value or number of caps you would wish or need, the zener on the SCR gate could be replaced with one or more 1n5408 diode's or a different diode or diode's could be used there and used in different combinations, a triac or even a mosfet could possiblly be used instead of the SCR anything is possible if it works.

Cheers all.

Hi Farmhand can you please post those schematics a little bigger cause they're too small.
Thanks

Alive

Hi Farmhand I was happy that the chicken is still alive and you continued to search for it. That's the true spirit. Perseverance

Totoalas interesting that video of the fan modification. I had one but in the past but now destroyed it cause I thought that it cannot be modified to a genny Ok thanks guys for the info that you're sharing.

[Farmhand]

I'll try to make a drawing later tonight, I would like to try this as well with a simple exciter circuit, as simple as possible so I can get some results quickly as an indication. I really don't know if it would work. Maybe someone with an exciter could try a small experiment soon ?

I think I have some sketches of an appropriate circuit here to go by. It's all in my head too but sometimes I forget some minor details. I nearly always get it wrong the first couple of times.

There is one thing. A good earth stake will most likely be needed. There might be a way around that too if thats impossible.

It was just an idea it doesn't hurt to aim high to start with we might get lucky. A piece of aluminium is much cheaper than a solar panel. There is always the solar cell to fall back on of course.

Here's a sketch of kinda what I had in mind, the neon would need to go and a low voltage zener used with another diode to charge a 1.2 / 1.3v battery, It works on a six volt battery I tried it, it charged to 6.4v but thats all. There are probably other ways to do the switching as well.

http://public.bay.livefilestore.com/...001.JPG?psid=1

Now if the plate "p" was a pyramid shape and near the exciter. Nah just kidding, I like pyramids, it would look neat if it worked as a pyramid shape, that would Sweet.

Actually with an exciter lighting lights completely wirelessly this should be easy, however i would advise precautions be taken incase of unexpected results ie higher than expected voltage or current, I would begin by short burst's if measurements are incremental or monitor it. We can only hope.



I only urge caution because I am not familiar with exciters, those that are, will know whats safe much better than me of course, but I had to say it.

Farmhand Battery Swapper Slayer Circuit Self Runner

Hi jbsolar, and welcome to the forum welcome also to automan, and thank you all for the kind words.
[
I have good news, I found my baby rooster this morning. Guruji made me think I shouldn't give up on it so easily and assume the lump I seen in the snake was it, So I look and look and I find him he was stuck under a upturned water tub. I am so happy about that. Thanks Guruji if it were not for you his fate would have been worse than being eaten.

Anyway my visitors got to laugh at me before they left.

Last night I dragged my little toy three pole Bedini out to demonstrate to people so I make a small video, it has some pretty lights and spins pretty fast.

YouTube - AlternateFarmhand1's Channel

I am determined to demonstrate the battery swapper today, I have finally got a firewire connection in this computer, for better vids hopefully.

Totalas I have been thinking that with an exciter in your circuit you would maybe be able to use a "plate P" setup, a (Tesla radiant energy receiver) instead of a solar panel. I don't really know but I think the exciter would make it work better than normal. It might not work good enough but I think it should be tried. I get good results putting mine near a AC Flouro, enough to charge a 6v battery very slowly. It may even be able make the setup self sustaining.

It's a fine day today.

Cheers all.

hi Farmhand
Self sustaining and self runner The GOLD MEDAL of the Exciter Circuit
A lot of ways to charge battery but no feedback/ charge /regulation/mechanism to the source
Yours is the answer to our prayers Allelujah Buddy

Any kind of power source let it be solar wind radiant energy Bedini and even HHO will solve half of the worlds climate change
Thanks to you guys in the forum
Let the fun begin

cheers

Here's the swapper video, I realised while making the vid that it's wired wrong, different to the drawing, but it works just different, i'll make a drwing of how it is now, when I work that out. Then i'll wire it like the drawing and try again.

Hope that makes sense.

Hi Farmhand sometimes bad luck should be taken in good luck cause maybe the chicken was not in the snake stomach maybe you could be his target when you faced that snake.
Please inform us when that circuit of yours would be ready from bugs that you're experiencing cause I am ready to build replicate it.
Thanks

Hi Totoalas, I had a close encounter yesterday with a very large venomous brown snake while I was looking for a missing baby chicken it must have been 8 to 10 feet long, a very effective killer, I found the chicken but it was inside the snake, I was very lucky to see it in time in the long grass. I was standing looking and listening when I happened to look down in front of me about two feet in front of me it was coiled and ready to strike and big enough it didn't feel the need to move. So I stared it in the eyes for a few seconds then retreated very slowly. Pheww. They always take the one's I want to keep for breeding. It will be a good feed for it, it was a hybrid meat chicken and was to be my new breeding rooster. That one snake has set back my breeding program by six months.

Anyway I have some people coming here to help me clean up around the buldings, and so I must focus on that for a day or two. I am putting some thought into the Power / Light / charger idea, all of that in one box and portable would be very usefull. I will be back after the weekend.

Cheers.

Hi Farmhand
Gud instinct to stare at the snake
In the Philipines we usually throw our shirts to the snake so as it concentrate on biting it

We usually catch snake 5 per week on an old fishing net wrapped around the fence with the chickens freely roaming our garden
A dog and goose usually augment the security

Take care
