@ Abbarue:

Yes, these were connected in series as someone on here suggested I try about 15 pages back.  (sorry I can't recall who, but they were correct)  The reason I put that off was my lights were still on my tree and connected to my color organ.  I took them off the tree yesterday and this made it easy to plug into each other.  I do believe the light output was higher with the circuit in series.  Plus, this was a lot faster than hooking up all of my test leads for a parallel circuit.  Thanks for your compliment.

@ Jesus:

Thank you.  Yes, this is still the original AA battery that came in the camera.  It is not rechargeable.  I have been using it for every experiment and to show all of my friends that have stopped by for the past month and a half.  It is still alive and kicking.  I guess I should measure the battery to see what is left on it.  I will do that when I get a chance.

This is better than christmas morning.

@AbbaRue, thank you for such an excellent explanation.   wow.

@Sparks, I was wanting to ask about creating a heat lamp from some IR leds whose rays were caught in a small greenhouse-like enclosure then whose heat was pushed out into a room for space heating. I know you are more inclined to theory, so, I want to ask if there is a theoretical stumbling block here that would need to be stepped over?

Along the same lines and from my less knowledgeable understanding than these 2 above posters, I awoke this morning wanting to post some thoughts that have been rumbling in my head ever since I was successful with the first fuji circuit.

Our man N Tesla never intended for us to be plugged in. He said he had it in mind to send the power over the waves or ethers or I don't know his exact words. Perhaps they would be helpful here.

His ideas centered around high frequency and, I have no doubt that he could have made (maybe did make) appliances that utilized the high frequency that he was preparing to send out from W...cliff.  We do know he made fixtures that were receivers which put out light.

I would like to suggest to those here who are interested, to start playing with motors, or non-motors that can perform the same functions as things we now have, but be driven by high frequency, not amps.

Our world could use a whole assortment of appliances that work at these high frequencies. I am talking about skill saws and blenders etc.

So, for those machinists and inventors so inclined... how about this idea?

@all
and along these lines, this is so easy to make a small energy source provide enough hi frequency to do a lot.  functionally a lot.

I just looked at my mk1/jt hybrid which I made yesterday and tested last night. That lit the array at the blazing level for 10 hours and the total drain on the battery was only 0.161V. So, in other words. I still have a well charged battery after 10 hours of producing blazing light.

I also want to ask those who are able to figure the calculations of these things to give me some numbers.

The battery is AAA and "holds" 750mA
The resistor is set at 1K ohm on the base of the 3904 transistor.
The transistor is only on for a part of the time, based on the resistance. and perhaps it also changes over time as the battery discharges some.

My little tests are OK for now, because I am doing them all the same etc.

Is there someone who would like to tackle this question of how much I am using in these tests?

Xee2 and AbbaRue came to mind, perhaps there are others.

Thank you,

@ jeanna

The ma-hr is the amount of energy the battery holds. A 750 ma-hr battery will supply 750 ma for one hour or 75 ma per hour for 10 hours. If you measure the current coming from the battery at start and end of each hour (by putting an ammeter is series with the battery) then take average (add together and divide by 2) you will get the ma-hr used during that hour (approximately). Do this for each hour the battery is used and add the results together to get the total ma-hours used. For example: you might use 30 ma the first hour, 25 ma the second hour, and 20 ma for the third hour, then you will have used 30+25+20=75 ma-hours from the battery. If the battery holds 750 ma-hrs, then you will have used 75/750 or 1/10th of the battery charge (10%).

Thank you xee2,

I don't have an ammeter. My dmm resoution is too low by a lot.

I don't know if my battery really holds 750mAH or if when it is exhausted it really holds zero.

All I can reliably measure is volts and ohms. I was guessing on the basis of what you are describing. And, I was hoping one could figure it out without a direct measurement.


Thank you,

jeanna

EDIT: I think I asked my question poorly.

I am wanting to know how many amps I am using because I don't have an ammeter.  I thought it could be done by calculation. sorry for foggy question.

Does anyone know of the relevant patents of Nikola Tesla that deal with wireless electricity?



Last night I took another KODAK that expired like 5 years ago and removed the board. All I did to this one was remove the big cap and battery and soldered one wire to a positive and one to a negative spot that Wilby showed me a while back. I was careful to not burn the board and just melted the solder enough to secure the wire. I didn’t remove anything this time. And, what do you know? It works! Mwahahahahaha!

I know it’s putting out some juice because while I had a couple of LED’s lit, my finger slipped and must’ve touched something wrong because I had a shocking experience :-D
I lit one LED and it was very bright.
I lit two LED’s in series and both were just as bright as with the one.
I put a third in series and all three were just as bright as with the one.

It was late so I set it aside for the night. But, when I get home(in just over an hour! YAY!) I am going to hook it to the multimeter and see what it’s putting out! It’s gotta be good because that shock got my attention real quick. It was those real good shocks like when you wear a real static filled sweater or something and touch a doorknob.
