I used AutoCAD, but I realized is not possible to export in .obj or .3ds , formats asked on the website to print them. so I ll have to try other program.

Tarsos Coil 3D
Hi Ledoc see if its ok or not
the complit file in Attachment
Microstation copy and Autocad

Nice work anwar2! but my idea at the beginning was to use this guide to wrap the coil. and to have a good reproductibility. In the case of your design it s not anymore possible :-( (see here: http://www.youtube.com/watch?v=uw2m7UfyvSM)
I finally received my RLC multimeter I measured for my coils these values:
RX coil : 12 mH
TX coil : 10.8 mH
normally the normal values are (source: asenkron):
RX: 11mH and TX: 10 mH (to confirme!!)
Do you think my values of coils are wrong?? I followed the must possible the instructions to make them!

If I use the equation of resonant frequency of an LC circuit
http://www.midnightscience.com/formu...lculators.html
I find for a frequency of 15,4khz:
- Rx: C=6n8 -> L=15.7mH
- Tx: C=10n -> L=10.7mH
Question! The coils RX and TX have to work at resonance point??
If it s the case I don t understand the value of 6n8?

if I use this coil calculator:
http://www.technick.net/public/code/...uctance_circle
with diameter = 18cm
permeability of copper = 0.999994
I find theoritical values:
Tx -> 14 mH
Rx -> 16 mH
???

to be both coils are same

Reviser resonance. Not in full resonance with transmitter.Make phase shift.No problem.Problem is high Q factor for ground search.Attached Files

ça y est, I finished to design the support for the coils with the correct dimensions. I attached the file.
Unfortunately to print this piece is more expensive that I believed,
39$ here: http://www.sculpteo.com
22.88$ here :http://www.shapeways.com
too expensive for me... pity I liked this ideaAttached Files

Greetings to everyone
success and everyone I'm a new member
I Tarsos 19.5 cm diameter detector coil
wrap over the pulley
schema
faithful to the original data as
This coil in the form of a circle
and then bending it by hand
D to the shape of
see you on the AC 120-130AC rx
this is true
For excellent after separation
swap 22k 47k trimpot located on the output coil
iron will be rejected
Get great value and then condans tx
the result will be good
one for me and reached 45-50 cm in 1euro
only 35 cm above
settings, and the crowing of the frequency shift will continue to
to be over my youtube video
I'm better now VLF pulse is to conduct research and respond to questions with respect to Tarsus left, but ceryan3200
