The bifilar pancake coil at its resonant frequency

Unfortunately your video shows very little in the way of correct power analysis method's--it has to be far better than that.

Hi Tinman, about your comment, I agree, that power analysis method's is not the best,but give a slight idea to people that not have a scope , and for sure you will agree that forum is not only you or me or a single minority , but a community of lot people that not have the same tools like some have .

About you say that i need make better than that in relation to "power analysis method's" , I left that job to people more skilled than me  like you with you bench tests . Good luck to feed back the system


Cheers

Don't think coax cable will work.  Tried a bunch of that.  But PCBs...   Yeah, that's the ticket.

You guys jump in with some specs and I'll design'm, post'm and you can play with'm.

try not to talk too much about 'slugs' at eating times! But have you noticed the cost of compact low voltage bell wire ? is it gold plated?
Anyway has anyone tried using obsolite coils of ribbon cable dead cheap and compact? just a thought that might be of use.

Wound another coil today,just to see what would happen.
I used 3mm multistrand wire,plastic insulated.

As expected,the capacitance value was low,as well as the inductance value.
So this means a higher operating frequency-but i did get it to work.

The lit bulb is where R1 go's in Partzman's circuit,and the unlit one has one leg between R1 and R2,and the other leg is at the P/in point.

My skill set is not with electronic's-although i am getting better lol.
My scope is also an el-cheapo,and one channel is misbehaving-but we carry on with what we have.

I did notice DogOne made a comment about ribbon cable being no good [and he was sad]

This is not the case at all.

AlienGrey
I will ask for a clarification on that today [I believe it is preferred in some cases of MEI work

thx
