weasel
please post spec of ur setup - coil spec /core size ,material ,number of transistors run batt size ect
guy

hello guy

i try and stick to the plan as far as possible

spool size is a bit diffrent than specified. core is 22mm length 8cm outer diameter aprox 9 cm
r60 welding rods 2.4mm diameter (smaller was not available)

coil itself 130 ft of 20 and 23 awg wire for the trigger and primary
or do you recomend longer
4 coils 8 fillar litzed
diodes 1N4001 and 1N4007
470 ohm resistor
transistor currently limited to bd243C later upgrade to mjl21164G
for the trigger 2 pots 100 ohm 10 turns each

weasel you have a 4 coils s filler 8 filler so its a 8x4= 32 transistor coil is core .866 length [tall]3.5/32 dia 3 .1/2 aprox
with welding rods about 1/8 dia
i m missing something
fill in blank
core dia._____
coil higth____
coil dia_____
2.4 dia welding rods x how many aprox
x 32 strand and 32 transistor
a few good close up pic go a long way

hello guy

wheel and frame are don so far

all the other pieces we still have to make
i keep you posted when we make the coils ( i presume this weekend)
just one question about the coils

what is better for our size of batterys?
more coils on the machine or bigger coils?

battery sizes 225AH input and 180AH charge side for reconditioning ( i have a lot of those to do)

weasel i never did batts that big .but if you do 4 coils 7 transistors per coil 32 trans if that dont do it .nothing will
when you fire that many trans it get hard to get enough umph out of trigger . not sure what the limit is
you should get it setup a good 225 up ft and a GOOD 180 on back and make sure it will charge batt that big
and note how long as it will take a lot longer . if it wont charge a big batt it cant fix a big batt

hello guy

second discharge on our current machine for the bad 180AH bat is now double then before
first discharge lasted 15 minutes we got now 29 minutes till 12 volt
so there is improvement and this is on the single coil machine

sounds like ur on ur way give the batt a good rest 4-5 hr

[wild weasel]

hello guy

the machine works this is for sure.
thanks john bedini for all the good things you did

and you guys all together for the support so far and making it happen all over the world

we on this end keep building and studying what happens and try to fiddle and play on the test rig...
the good rig is in the build and i know there will be setbacks and other problems to come but hey thats the fun of it.

frame done


now we wait for the rest to arrive

Looking good! Is the bracket you are using steel? It might get caught up in the magnetic fields from the magnets and coil, you'd be surprised the distance the field of a ferrite magnet actually is, I certainly was when playing with some metal shavings a little while ago, so it might pay to use a timber or brass bracket instead. You will notice a lot of SSG builders try and keep the metals to a minimum in their builds. That's just my novice observation, so take it with a grain of salt.

Great work in any case!

Thanks

good point jelloir

did not think about this before.... but you might be right after all

update on the wheel

magnets arrived and installed
free spin time 21 minutes so nice running on new bearings ( just wondering after run in period)


now waiting for the other components to arrive to build the boards and coils

on the back we make 3 kopper pipe rings to connect all leads
pics follow

hello guy

in the meantime our bat is now hitting 14 volts under charge for the first time
discharge remains a bit the same for now but voltages are rising slowly

?????
what do you mean

edit
i got what you mean break in run on bearings !!!

[wild weasel]

ok we have been fiddling arround a bit today with the new toy.
components are for now on a breadboard, i know its not good but its fine for fiddling.....

but..... for fun we had this old 2 fillar coil hanging arround from the verry first step .....
i put it on as a seperate trigger..... so the main coil is now wired only to transistors and trigger goes to both fillars on the other coil and we can play arround with timing of the attraction



now we notice the folowing.
rpm goes up from 280RPM from standard single coil setup to 400 rpm..... with same base resistance on the trigger and looking for good timing on the trigger coil.
also here big diffrences depending on the timing from 200 rpm to 400

but a large drop on amps on the charge side. 1 amp in single coil setup to 0.5 amps at 300 rpm or 0.3 at 400rpm

annyone outthere been playing with this setup???

i have to say that the trigger coil has 900 turns of wire on it
maybe this is to much for matching the setup of the other coil.......

kind regards
weasel
