Not really any reason other than the capacity of the batts and some expermintation.

Big batteries take a lot of time to show something unless the load is pretty big. I've been thinking of going down to some 9V nickel metal hydride batteries just to see them squawk a little. My 17ah batteries are doing well with the 20W lamps, even lighting them up. I probably should just leave it alone for a while and see what they do, but it takes a long time for them to move up or down even with that load. I guess that is a good thing, as 1.66 amps is really too much for the C20 rate....but it gets pumped back in at .84 amps, which they would like just fine. Maybe C20 has nothing to do with the TS, as Matthew has said, but time will tell.

Let us not forget to "load" these batts down from time to time. Just as you would in real life. If we charge, charge, charge, the batts may forget what their actual purpose is.
This picture just posted by John took me back to his website - and I started reading Tesla chapter again. I also discovered some new pages. Didn't see them before. No matter how many times I read, there is always something to think about.

The attached Word document is my interpertation of bit's code. I want to mention that as I understand older pics you have to pay for incrementing and looping. So I have added a small delay at the end of the loops to visualize this. From bit's results this must not be important or is not occurring!

ps. Still trying to figure out how to insert pictures, where do you guys save your pictures?
"In each location the device suffered not one degree of diminished output. Appliances usually tested simultaneously in these desert locales included thirty-five lamps each rated at one hundred fifty watts, a one thousand watt hand iron, a heater, and a fan. Moray himself wished to test whether the device would drive a plane or submarine. The device was taken up in a plane and submerged in a watertight container at the bottom of a lake. In each case the output remained the same"
Didnt John say something about testing a device sealed in a box in the lake?

Quote from Bits: "Vissie, think of Q1 and Q2 as a "normally open" switches and Q9 and Q10 as "normally closed" switches. When I fire Q1 (pin 4) I need to open the path Q9 is in to avoid the recirculating current (yes the same current that smoked your diodes). Q9 and Q10 are PNP tranny's. When you bias them they open."

Can you tell us if your 4 batteries charge up to the same voltage when leaving it on charge mode for about 12 hours and to what level do they charge?
Did you run a load between the two negative terminals at a higher frequency to see how long it last and then switch it to charge again with the other 2 loads to see how quickly it charge up again?
Can you please try and explain how you get that pnp`s to be in normally close mode (on mode) without biasing them. As I understand it a current has to flow out of the base to switch it on by connecting a resistor between base and collector. Then when the opto switch the higher voltage from the 24v series side will switch it off.
Obviously it is working. We can see it on the videos. But I just cannot see how that pnp`s can close and conduct by itself without biasing.
Another question. Lets assume that Q9 and Q10 are normally closed. In your latest code Q1 is on for 1.5 sec(or 800msec) and Q9 only switch OFF for the last 200msec. Why does the recirculating current , (that blows diodes) do not cause any trouble during the first 600msec? And how can it release pressure?

Vissie, my observations thus far is the batts come up almost to the same level over time. I have not run loads at a different frequency yet, but intend to do so. I need to get back to you on Q9, Q10. I need accomplish some briefings for my day job, that are due in about 2 hours.
Thanks

Nice charts Jason / Vtech
Update, team I appoligize for posting an incorrect drawing setup for Q9, Q10. This is how I have it in real life. I am sure this has caused you some hair pulling experiences.

Lots of v.interesting material. I'm still reading it. It seems that they were updated not long ago. Thank you John
BTW, This is my idea of analog switching sequencer for TS. These two optos switching 2N3904 are not necessary, I just have more optos than transistors. It can be triggered other ways. Top 555 is OFF timer, bottom - ON timer(left part of circuit). Transistor isn't critical either, any npn will work. Those 2 555's on the right are delayed recovery circuits. They're triggered from the same source but will delay response (1uF and pot) providing adjustable time for Q9/Q10 to open. This isn't as "smart" as digital sensing and using comparators would be more appropriate. But then it will get even more complex.... and one may ask - why bother, just go digital If you catch any mistakes...you know, they happen )
