Thanks Tinsel, I'm sure SeaMonkey has already told me why but I was likely in the land of pain and pills and forgot.  :-[ Thanks .

MileHigh, I also purchased a quite good 1/6 amp current pulse charger with a four stage charging algorithm. When the battery is first
connected and the unit turned on it checks for reverse polarity connection, Low voltage (short circuit) and open circuit in the battery.
The if the battery is real low it gives a 1 minute 1 amp charge and then analyzes what to do next, if the battery is ok but a bit sad
(sulfated) it gives the battery a "refresh" about 10 minutes (or however long it needs) of about 500 mA current which I think is HF small uF cap discharges.
When that is finished it goes to bulk charging (constant current) then it goes to Absorption (constant voltage) for a while then it floats the batteries at 13.6 volts.

It calls it's action in charging a Pulsing Current Pump.

Model is obsolete - MB-3624 - Power Tech Plus - but similar units of a later model are available.

It's a sealed unit and small and light, only drawback I had was a fuse in the output wire had a poor connection and made the wire hot. Other than that it works pretty good. But it doesn't go - tick....tick...tick....and it only has one button, grrrrr.

..

Last night I used my cap pulser to charge the 14 Amp Hour motorcycle battery right up and to know when it's fully charged when charging it with LF pulses is not easy, when the battery is showing about 13.8 volts mostly but the pulses take the voltage over 14.6 then it's charged. The MC battery was making all kinds of funny belching, bubbling, fizzing and buzzing noises when it got towards being charged, I stated to get concerned when I heard the battery "buzz". This morning I connected it to the 70 Watt solar setup and it took good current for a brief moment but went directly to fully charged and floating.

The circuit was going tick...tick...tick... with the discharges and the battery every now and then went bzzzzzz, bloop,bloop, all the while making the sound of a freshly opened coke.  ;D


P.S. I gotta say that 2 Hz is the lowest frequency "resonant charging circuit" I have ever put together. Very low "Q" for sure. But it still works a bit.  8)

Farmhand:

I am glad you are having fun.  When you program a micro, and especially when you program it in machine language, it's like you are a god.  No operating system, just the first bytes of code that you put into the memory location when the device comes out of reset.  You are probably aware of how in the 70s and early 80s programmers would squeeze their machine language code into 8192 bytes of memory.  They accomplished things that nowadays probably gobble up a few megabytes of space.

When Bedini released his solar-panel-based pulse battery charger, it started with the deke out about how they allegedly had to detune it so they wouldn't "get in trouble."  My assumption is that it was very low tech and they hid that fact with the liberal application of potting compound.  It would have been fun to put a current sensing resistor on the output and scope it to see how it performed.  The conclusion would probably have been "dumb."

I tried the search "fuzzy logic toaster" and there are no direct hits!  Damn!

I'll settle for being an archangel, and write my code in c++.

 :P


Try "fuzzy logic clothes dryer"...   ;)

 :D I just gotta write whatever I can that will cause what I want to happen to happen. I was convinced that if I got a picaxe 08 I would be able to write simple code to do pwm outputs and stuff. Then when I got it and learned some commands I was able to do more than I ever expected, and know how much more is possible, almost endless possibilities.

Some of the commands are real doozies, the " if...then \ elseif...then \ else \ endif " takes the cake and I did manage to use it properly in one program. Boy was I chuffed.  :-[

I did also teach myself to assemble computers and flash BIOS chips and overclock the heck out of old 939 socket computers, I managed to overclock an Opteron 165 (1800 MHz) Stock up to 3200 MHz with only air cooling. Took a lot of tweaking the memory timings to have it run stable with only a small increase in core and memory voltages. I think the damp has killed all my old "fast" computer parts. I can get carried away with things. My bad.

This might make you laugh, a sign of generations, "Back when I was into building fast computers we had to use multiple mechanical hard discs and connect them up in a RAID 0 set up to get more data speed and then we only had a Hard disc not even nearly as fast as a Solid State drive".

Does anyone even do RAID 0 for speed anymore ?  Full of pitfalls a RAID 0 config.

I think it was made by Rockwell, but I can't remember the name of it.  You wrote assembler code on paper, converted it into hex by hand, and even calculated your jump-to addresses.  Then you entered the program byte by byte into memory with a hex keypad.  Then you hit the reset button and ran your program.

I think it's arguable that these kit boards in the late 70s and early 80s launched the computer revolution.  They were not toys, they were the real thing at the time.

Looking back in time sucked into the inverse-Moore vortex.  Try ripping a Blu-ray disc with one of these babies!
