hello folks

first of all thanks tom for the good chat we had
on the other hand it puts our mind again at work
so there we are again

what happens if you connect diffrent independent cirquits to the same primary?
wil this work or do we fry all systems?

the point is that we could get our hands on a storage battery bank.
and if possible run multiple wheels from this source.

kind regards

it depends upon the mode you run your machines. in standard mode primary pos is attached to charge negative. that would place all the charge negs in parallel. which will mess with your systems impedance. a capacitor before each machine's primary in parallel will help if you choose to run this way.

thanks tom

so i put a cap before every coil going of the primary pos.
anny sugestion on the size?

kind regards

double the battery voltage of the primary, try 15000 uf. you need good protocols for hooking and unhooking.

hello tom

we will try doubling the input but first i need an automation on my discharge.
on 12 volt i charge a 225AH battery to 15 volt in 20 hours and i can follow this nicely
on 24 volt input i cant leave it unnatended for the day. it would be at 15 volt or above way to long to my liking (it goes beyond 16volt on 24 input)
we try to figgure something out with a arduino to automaticly switch a light on the battery when it hits 15 volt and shut off the light at 12.4
anny one here who has experiance with programming a arduino who can write the software and tell us what parts we need?

kind regards

I took it that he meant the capacitor should be able to handle twice the battery voltage.

hello brian

this for sure but he wants me to go to 24 volt input as well
i just have to make some preparation to be able to handle it.

hello tom

good info but i prefer to go with the arduino setup
this we can program to do several functions in 1 unit

basicly the idea is as follows

first of all to have a adjustible voltage range for on and off mode
in standard setup switch relais on at 15 volt
shut down at 12.4 volt
monitor discharge cycle and time it
keep a log on the battery performance

this coupled to a pc with internet so i can monitor what is happening from remote

so annybody who can program this and is willing to do so..... let us know

kind regards

weasel,

finaly i'm also a member of the forum.
it took time but here i am.

hello folks

here some scope pics and rpm measurement


i believe i can not see the spike itself on my scope
but just to know what you think of it?

kind regards
weasel

[Tom C]

it is there it is just too fast for your scope, try changing the width of the wave and focus on the front edge of the "h"

[wild weasel]

hello tom

i was thinking the same this is a simple scope.
we cant get a better focus than this one

just another question regarding matching transistors
i suppose the more coils we add to a system all the transistors of all coils need to be the same. not just per coil
this needs indeed a large number of transistors just to get a matching set big enough to make a larger machine

kind regards
stephan and serge

[Tom C]

it is all about performance. we can do a bulk match for you, although you are primarily desulphating so COP is not as much of a concern for you. your efficiency will still be fairly hi if you match for each coil, that is the most important.
