For those that might have the West Mountain Radio
CBA II battery load tester that interfaces to a PC,
West Mountain now has a CBA III with some new
software enhancements. Some of those enhancements
are available as a download so as to upgrade the
CBA-II. I've downloaded the program but have not
yet checked it out. Just a heads up
I bought two white bright 10mm leds today
I connected them in parallel with polarities facing in two different directions so they could conduct in both directions.
They are very bright and also give you a good indication of the slow frequencies around 1 Hz and the off time in between (duty cycle) which is difficult to read on a scope.
After an hour it looked like the battery pick up some voltage so I connected the supply of the flip flop also to the battery. That pulled the battery voltage down a bit and it looked like it keeps on loosing voltage. So I disconnected it again
I will leave it overnight running at about 1 Hz at about 25% duty cycle
With the setup I posted earlier, I haven't been able to get a net gain in charge yet. I decided to try a separate battery to power the switching. The battery negatives had to be tied together for the transistors to fire. I attached two scope shots where the battery maintained a steady 12.12V. I ran it overnight with the lowest duty cycle. The battery was still sitting at 12.12v when I shut it down this morning. I will post the resting voltage when I get home tonight.
In the scope shots, the negative of the probe was connected to the battery positive side of the load (#47 bulb) and the probe tip was connected to the cap positive side of the load. So the pulses in the negative direction show the caps charging in parallel across the load and the pulse in the positive direction is the caps discharging in series across the load (Correct me if I'm wrong). The bulb was barely lit in the 2hz scope shot and not lit at all in the the other scope shot.
Is this the proper way and place to take the scope reading?
@JB. Is this the waveform we are after?
If there are other test points that anyone would like to see on the scope, let me know where/how you want the probe(s) hooked up in the circuit and I will post the scope shot.
I can well appreciate how frustrating it is to try and get data
off the TSw without loops and unwanted interactions.
One possibility comes to mind as follows: If a person could use a
voltage-controlled oscillator for the measurement (a BIG If),
it might be possible to take the vxo signal to an opto of suitable
bandwidth and thus interface an optically-isolated pulse
train into one of the timer channels of the PIC. Another possibility
is the ADUM-series of isolators by Analog Devices. Use another PIC
timer's interrupt service routine to read the vxo accumulator
and then reset it. This is just a concept that might have some
merit, and again, maybe not. If you've already been down this
pathway and found it lacking, then please pardon my interruption.
Hi Alex
I also probe over the load. If you probe over the 2 caps it looks about the same, only the dc level change.
Use two bright 10mm white led`s in parralel but with polarities reversed as your load. You will see on the scope that the voltage pulse over each diode is about 3v. They flash very bright and at least give you the feeling that something is happening!
If you look at the photos that John posted in the beginning of his posts of his TS , you will see that there are 2 large white led`s.
In the one photo one of them are lit and in the next photo the other one.

I thought they were in series with optos It makes sense. I went back to my SC after being away for couple weeks. I used two LED reversed instead of bulb. I tried first with one at the time; depending which i leave in the circuit either upper or lower spike is getting smaller. I also tried couple more inductors; air and with iron core. Iron core gives unequal spike (upper v.s lower). My wave looks like the one posted by Alex but when I increase freq. by reducing oscillator cap to 10nF I'm also getting bell shaped resonating wave. No increase in charging battery yet .

I ask this question before and I see some guys also noticed it
On John`s latest circuit that he posted he left the parallel transistors out and only inserted extra diodes
In the attachment below I drew only the top positive part. If you follow the path when Q1 switch on, it looks like a short over the top left battery through D1, D2, D3, D4 and Q1
The same will happen in the bottom negative part, but at least there we will have 2 light bulbs instead of diodes.
John if you read this can you please shed some light on this
I already built a small pc board for this circuit, but will probably only get time to build it after Christmas.
I wish everybody on this forum a very happy Christmas and a successful free energy year

I noticed that as well and noted it in post #1037. It must work considering all the potentials when Q1 is switched on. I'm sure JB would have posted a reply if it was a problem. He is meticulous in his work. There is something we may be overlooking/misunderstanding so we must build it "as is" to find out for ourselves how the potentials behave in this simplified circuit.
The resting voltage on the battery from my last test was 12.16v. So it dropped by 0.02v. I still have several other loads to try and will report on them.
