all, i will be placing an order for the cores for the VIC Monday, as discussed before.

i have a list here and need to know if i got everyone that wanted one.

also note that we do not know if this is the correct perm... and the min order is 10 pics ( 5 sets) so if you want to wait till i see if the measurements are correct then just wait. as long as i get 5 people... we are good...

the wait time is 4-6 weeks!!! so yeah...

its 106$ for the set of cores (5 pieces at $53.41 ea. MN67 material.) perm is 1200

also if your in the US  its 5$ for shipping.

if your in a another country i think i can ship for about 10-15$ but this has no tracking... so its like 60-80$ with tracking... that's your call. depending on your location. if i get your address i will have a better idea of price.

IF YOUR ORDERING I NEED YOU TO POST HERE THAT YOU WANT ONE AND THEN SEND ME A PM WITH YOUR ADDRESS AND I WILL TELL YOU HOW TO SEND ME THE FUNDING.

sweet! looking forward to it!  

Thanks! let me know by 3-31-12 please.

~Russ

I'm in for one set. :cool:

Hey Russ,

Yeah I'll take one.  I can donate mine to you for testing.  Let me know where and when to send the cash.

Thanks
Chris

Russ,

Did you measure the resistance of one 3 inch WFC with a type of water in it?
Just wondering...

[attachment=1125]Filled up a bobbin with 29 gauge heavy build.
55.5 ohms.
Should get the 30 gauge heavy build tomorrow and try again.

ummmm... looks like no.not with the new setup. i took Capacitance readings but not resistance. i will do that.

Yeah, first time I got to play with actual size bobbin. Can put 3000 turns of 29 on my round bobbins. I have to try everything out for myself. Way too much “speculation info” out there.

If you can send me an email with the total including shipping.
Thanks again,

I was already confirmed wasn't i? If not, ... i want a set as well :)

The reason why I ask.

Distiled water 1 µS/cm
Rain water 30-60 µS/cm
Sea water 42 mS/cm = 42.000 µS/cm
Drinking water 500-2.000 µS/cm

ok, so here is the list of people that are ordering. and have paid/send funds.

if your not on the list please inform me.

it looks like i will need to wait till the funds will transfer to my bank. Then i will place the order. so it may be 2-3 days... i was hoping for Monday to place the order but i need to wait till paypal transfers the funds... so it may be Wednesday... ill get it ordered asap!  

i will keep everyone informed on when they have them done and when i get them shipped here on this thread. they quoted me 4-5 weeks for lead time...

that's s chunk of change... hope for the best!

thanks guys! ~Russ

I think we are on the right track with those cores, I only wish the wait time was not so long:(

Just started winding the coils today using my mini lathe. First layer on the primary came out to about 115 turns. I only wish I could set the auto feed right.

One thing I recommend to anyone winding these coils (after much frusteration) is to make a turns counter. I made one (see pic) using a pedometer from the dollar store and a miniature reed switch from ebay. Total cost = $4. The turns counter saves a great deal of time and hassle, and for $4 it's really a gimmie!

Hope everybody's building projects are going well, I feel like I'm behind....But then again with a few weeks for the cores I'm sure I'll catch up:)

real nice setup, i also used a calculator and a pedometer in this setup:

What I am telling is that a 'NORMAL' capacitor wouldn't have 'RESISTANCE' to form a critically damped RLC to create 'UNIPOLAR' charging pulses.

What type of water are you going for?

So far mine has worked out well...But I also noticed if you go too fast it will not keep up. Winding these coils I could not go very fast as I want to make sure there are no overlaps or gaps between windings (that causes increased winding capacitance).

I must say your work on the EPG is very impressive...Hope to see you get it working one day:)

Say guy's this could be adapted to wind coils with, just using the stepper motor, not the lathe.

I've thought some on that, would be cool to use a stepper to do the winding also.  Then turns can be calculated by steps in the arduino.  Could also use an optical wheel to calculate wire length.  Would have to go through the same calibration steps as a reprap.  Too bad I don't know much about arduino programming. lol

Yes to pricey, but that just gave me another idea. If someone has an old style fishing reel, they could use the gearbox off of it to feed the wire from the left to the right and back again, drive it from the stepper while it is turning the spool to be wound, or you could print gears with an automatic reversing lever to do the same thing.

Russ have you seen this from Irondmaxx

https://www.youtube.com/watch?v=q6jOmtRt5tA&feature=digest_mon
He says the reason for the gap is to adjust the PM of the core, so if we buy 2000 PM we could adjust what is needed, if we buy 1000PM we won't . The guy is very irritating but he could be right, don't know, you make the choice and I will follow, just want to make an educated decision which I know you will, I trust your judgement, thanks Jeff.

I've seen that one working on Youtube.  Pretty awesome.  I think we could print one out with all the pieces parts to make it go.  If we build it ... they will come(programmers that is)..:P

I've had some of those fishing reels, they feed the line so that it crosses each layer a little bit so that the line doesn't get pulled down into the spool when a fish hits.  I think we are looking for a slight movement of the thickness of the wire per turn.
