Delta Pulse

[detecto]

1. you use high value of PPS.
2. you set big PULSE WIDTH value. decrease it to 250-300 usec.
3. you have low inductivity of the coil. increase it to 400-450 uH.

I will try this.
Thank you kt315

my last update - for more stable working I did set an impulse converter. so DP works from 8 pcs of AA type now.

Delta pulse is good detector, i only hate big current consumpation up to 250mA with full detection
Ofcourse Delta can be improved with couple little mods.

Hi KT315
maybe a silly question, but have you made a fully 100% working delta pulse ?

hi 6666,

I did Delta Pulse on PCB made of one guy from Latvija, but he refuses to answer now. I did decide to redesign and to order a bunch of PCB's so everybody can build DP without problem. My DP had been sold to guy in Ukraina. Yes, DP is 100% working, very sensitive and stable. For example, in a field I lift the coil up on head level and there is NOT a sound from the speaker.

i have build my delta pulse since a year, it don't work , i would to fix the problems, so i need your help .
- a continued sound from speaker.
- TL062 (D5) is very hot

please i need your help

Hello Apocalypto
It's hard to help from here.
I can only say that the TL062 is not power device. Its power consumption is very low so not to take temperature.
Check the PCB and compare with the scheme, it is likely that there is any short circuit between the tracks, use a magnifying glass. Check the value and the correct installation of the nearby component.
Replace the TL062, may be damaged.

noticed there is free section of D10 (U10 in my schematic attached). IMO it may be used for auto-reset on turn-on.

Good idea, KT315

Maybe anybody has did a schematic in OrCAD or P-CAD? would be greatly appreciated if you share it.

all the best

Recommends everybody else. :-)
I observed the developments. The Iranian kid's modifications and it they were over here I assured an opportunity that the frequency, the dumping resistors on the motherboard on his basis can be made change in let him be allowed to be. I modified the trussings. A-A, B-B I was looking for a road on the motherboard for the electrons.

Please contoll my modifications! Thnx!

You should write what you are modified, checking separete components is not easy,
btw i don't recomand you to use sprint layot for drawing PCB, it's wery poor cad software,
i used it and now i am not satisfied with it.
Try to use diptrace its wery good software easy to use and much bether than sprint layot.
I recomand it to all...
