Re: Oscilloscope vs Function Generator
« Reply #540 on: April 24, 2011, 08:15:06 PM »
Hi Altrez,

Good to hear from you.  I know you said that an oscilloscope was a must have for the project, but I thought you also said that a function generator would make it much easier to tune the JT than an oscilloscope.  Did I misunderstand that?  Wow, I hope not because I didn't have $150 to throw away.

P.S.:  I already had an oscilloscope but I wanted to take all the guess work out of this project.  I want it to succeed very badly.

Best Regards,
Slovenia

It does make it much easier you simply dial the function generator to the required frequency an you are done.

Hi Altrez,

I was just going by the two posts I have coped below.  If I misunderstood, I'll make the best of it. 
Thanks for your willingness to help on this project!!!

Hi Superman,
You should have a variac, adjustable transformer.  They are fairly cheap on e-bay and come in really handy for our work.  I got an industrial one for $10 on e-bay.  You will need a scope to adjust your potentiometer to the desired frequencies.  I think you can do without the function generator.

12v car / lantern battery
Variacs are great to have this is true.  However, I am going to show you a way to run this from a 12v car / lantern battery. 
Convert to AC
We will convert to AC that can produce a clean sine wave at the correct frequency rage, then output that to our transducers.
Dedicated Circuit for Piezo
You need to remember that we are simply making a dedicated circuit for the piezo and not using the standardized one that comes with the transducer..
Function Generator
The function generator is done ready to go.  All you have to do is change the dial to the correct frequency select your wave form and output voltage.  Its a very simple way to tinker with the right frequency.   AND, I RECOMMEND that if you have the cash to pick one up for  prototyping.
No Guess Work

When you have it tuned in.  Then you produce the correct circuit.  It's so very easy to do.  Takes all the guess work out of the circuit.

We are going to use a battery.  The reason for the adjustable DC power supply is to really get the input power tuned in. Then we will run from the correct battery.
Frequency Generator
Think about it like this. We are building a frequency generator based on the information we have.  If you buy a Function generator then you can fine tune everything to your personal reaction chamber. Its the easy way to go and it will save you hours of hard work and headaches in the long run.  I encourage you to look up how one works then you will completely understand where I am coming from.

If you do not have scope you will have a very hard time understanding how all this is working. You can get one form eBay for $60 its pretty much a requirement.

-Altrez

The function generator is the same as tuning a Joule Thief. You can do the whole design an testing phase with the Function Gen an once you have it perfect then you make the Joule Thief that outputs what you want.

So for eaxmple when you get your pizeo all you need to do is clip the leads from the Funtion Gen to it an move the dial on the gen until yiou reach the perfect balance.

You then write down the output that is displayed on the function generator. Verify it with a scope an then build the Joule Thief an put it in place on the Function Generator for a portable device.

Hi Altrez,

You mentioned that you are going to show us how to utilize a 12v car / lantern battery for our experiment in lieu of a variac.  Would you give us an idea where we can pick up this particular battery and what if anything else is needed to go with it such as but not limited to chargers?  Thanks!!

P.S.:  Also, does it matter what range of potentiometers we use with our joule thief circuit?  I want to get the one that will allow for the best fine tuning ability.   Thanks!!

Best Regards,
Slovenia

Any 12v 7 amp hour or above battery should work. So basically you could use two 6v battery's as well.

I like to have 4 pot's to test with to get the best sweep. a 5k a 10k a 100k an a 1Meg ohm should work an be less then $10 bucks and give you a lot of sweep.

Do you have any other questions? I am glad to help :) However I have a huge work week ahead of me so my posts my be a bit delayed.

It sounds like the function generator will be a good device to have around.  Thanks for the clarification Altrez!!

No more questions at the present time.  I'm still waiting on parts and trying to get caught up with all my reading.  It looks like I need to get some more pots.  Thanks for all you have shared Altrez!!  With your help we can make this happen, and then we'll have some prototypes to share with everyone.  Thanks!!!

Cost of BK Function Generator
« Reply #546 on: April 24, 2011, 10:47:16 PM »
Hi e2matrix,

Sorry, I didn't see your question until today, Sunday April 24.  The cost of the BK function generator was $65 plus $14.95 S&H.  I just orders a new one instead.  The BK looked very nice and was guaranteed to work.  I saw it on e-bay if you want to look into it.

Best Regards,
Slovenia

how much was the BK?

Pond Fogger Circuit Query
« Reply #547 on: April 26, 2011, 02:08:23 AM »
Hi Altrez,

I did think of another question.  I know this is a very busy week for you too, so no hurry getting back on it.  I know that we are using the JT frequency generator to adjust our piezo transducer instead of the circuit that comes as part of our pond fogger setup.  So, do we have to tear out the circuit that came with the pond fogger or can we just use it along with the JT frequency generator the way it is?  Thanks for all your help.  It's very much appreciated.

Best Regards,
Slovenia

This is Altrez JT frequency generator circuit as I understand it.

If I'm in error, please correct me.  Thanks!!

You need just the piezo not the rest.

JT Parts Came In
« Reply #553 on: April 26, 2011, 11:35:14 PM »
Hi Altrez,

Well, the rest of my JT parts just came in today, so I'm ready to put my JT together.  You said that my circuit diagram for the JT needed some tweaking.  Do you have time to elaborate?  I know it's a very busy week for you.  Thanks!!

It might need more or less turns on the toroid an the resistance is key. Put it together and tell me what the output is please.
