delta pluse coil 17 inch

hi kt315 i built delta plus it working good thank's to help. actually i need a know of delta pluse 17 inch diameter coil how many turn's and wire awg and inductance

coil for delta pluse

this is my testing coil it working ..........

rajesh, google net and you will see much on-line Inductance Calculator: Square Loop like this example.

delta pluse coil

hi kt 315 i'm using gary inductance calculator but i don't know which inductance is better for delta pluse i mean 300 uh or 350 uh or 400uh 0r 450 uh and which wire awg 22 or 26awg ............

[kt315]

if you take a look on schematic you will note the data on them ramka coil - 16 turns on 1100 mm side length. this gives approx 450-500 uH.

hi kt 315 i have submit my coil image upper 13.5/13.5 inch squer size. this is right for delta pluse or wrong ?.....

take stranded wire 2-2,5 mm diameter. your 22 AWG leave on another projects. it IS DEEPER! you must do all details VERY ELABORETED! ALL PARTS OF IT!

hi kt 315 what mean to say elaborted actually i need to know which guage of wire you are used 25 turns is about right for this coil with a 53.5" perimeter. This is equal to a 17" round coil.....rajesh

hi kt315,
my DP work stable but poor detecting ,a canet koka 40 cm..........verry poor ..........
with : R5=2.2k 1w ; R6=680R ; R23,24,25,26=4k7 5% ; D4=TL071 i didn't find LF357 ; C30=10.000uf ; irf840
coil=40cm diameter ,23tr ,0.50mm wire , resistance 2.6R
thanks for helping

[kt315]

did this mod, but still did not tested at nature. thinking it would be increase the stability. enjoy!

hi kt315,
you mean replace irf840 with 7909 ?
i find a mistake in compesant 1.5nf , now my DP is better it can detect a canet coka at 85cm , but is not stable
thanks for helping

Hi KT315.

Abot changing values on caps, cona this solve inestability on delta pulse?
My case is that some Delpa Pulse that i had build, have the problem of inestability, when you play with some controls like delay or threshold too.
Any way the detector keeps goood power detection, but has i said in some setup situations it gets somoe inestability.
Any ideas.
Thanks my friend

yes, certainly you can use 1,2-2,2 nF and the PC power supply. I use power supply from a modem for test and battery charge, with -5 and +12 V output.

I do not mean to replace MOS-FET with 7909. you add this IC for to supply all schematic by stabilised voltage. test all accumulators - this is your problem! one AA size unit must give you 9-10 A of current on your digital tester in full charged state! if you do not get this current - you do not get the stability NEVER MORE!

hi Nelson. thinking it is normal you will get the sound increase if you turn/play the controls, especially in increase of their value side. DP is very sensitive STATIC schematic and every such action will give the sound increase. on every the turn/tune I also push the knob RESET. I get an unstability if the battery already has been discharged after some work. now I go with 300 us of POWER PULSE WIDTH.

hi raff can you tell me 0.5mm wire = which a.w.g. copper
