Delta Pulse

[kt315]

all adjusments will be get automatically. DP was projected for fully dumbs, for a kitchen home worker female. DP has only one (ONE) pot for adjusment - P.P.S.
tune 120Hz for US standart electrical net and 100Hz for EU standart electrical net, this decreases the interference.

no difference. they both are same.



increase C1 and/or R1 value



increase C3 and/or R4.

VERY seems your nominals of componets ARE WRONG and you DO NOT MEASURE ALL COMPONENTS BEFORE SOLDERING

thanks my delta pulse work but i need to find best adjustment Mr Kt315,for all Tp points .
regards
my coil is 21m 0.7wire 495mkh.

no difference. they both are same.

i use ne556 instead of lm556, i have 80mks and perid of this on ne556-5 is 2.5mks ( not 10ms)
and i get in ne556-9 350hz

increase C1 and/or R1 value

but the it is 17mks not 100-500mks

increase C3 and/or R4.

so ne556 have more DIFFERENCE to lm556 ???

Hi KT315

Good work .but what version please .I cant open it.

thanks

hi, it is strangely. version at pic

Where is the large electrolytic cap across battery input terminal?

did you read what GS wrote? http://www.geotech1.com/forums/showt...21088-Power-pi This result is ( delta pulse) but with huge panel
while size of pcb is only 153 x 67mm. battery itself is the electrolitic cap. good batt=good cap, bad batt=low cap.
electrolitic cap across battery does not encrease stability, this was experimintally tested. if you take even 10000uF
it will be << (much less) than battery capacitance. anyway you can add the caps locating its outside.

Some capacitors are with too large raster for given value, 3 electrolytics too big.

electrolitics have standart formfactor. not miniature. here at pic is 220uF 16V electrolitic.

Spacing from chips to nearest components reduced to 100mil, 150 is recommended...

where you was been early I did King Cobra board? )) read GS, for him the DP board is huge. IMO with all pots at board it has enough size.
if I will do 150 mil spacing some critical traces will be still more longer. this is not optimal.

better expand board to some round dimension, like 160x80mm and less crammed. Make it best in the world, I will find something to criticize...in absence of some more useful task to do.

round dimension may be in inches too. for american people. for you - I believe you are european man - inches are not round dimension and something un-harmonic
un-balanced bad.

thanks.

top side. check.

where you see 45cm here at pics?

[g.s]

kt 315 So we consider lesser coil for delta 45cm the 50cm..
