Delta pulse help

Dear friends

I read md4u forum about this delta pulse schema is not correct.
some connection is false.İf so ivconic or geo could sent near photo about
delta pulse.
below link about above subject.

Hi all,
friends this is my delta pulse with lcd project. Do you like it?

[Geo]

What do you read with LCD ??

[fish1985]

My project is in design level now. I read first 250uS after pulse from lcd.



I'm Turkish. This site is our detector forum :

Hi Fish1985.
If you read right the fall pulse then you can do a typical discrimination for small and medium size objects.

I have found mistakes when compared distributings it:
1- R33 sat on a path 10 leg U10 - 2 leg U7, небыло crosspieces between
2- and 6 leg 555.2 æ16 it is connected to a path 2,5 leg U6-R27, C11 it is not connected with 4 leg U4
rus
ошибки я нашел когда сравнивал разводки это:
1- R33 сидел на дорожке 10 нога
U10 - 2 нога U7,
небыло перемычки между 2 и 6 ногой 555.
2- С16 соединен с дорожкой 2,5 нога U6- R27,
C11 не соединен с 4ой ногой U4.

Hi all. Schematics of Delta Pulse and XR71p are right . Pcb from XR71p is ok and tested . Another pcb for DP that you can find at this forum is ok except one jump that you must put at pin2 and pin6 of 555 (audio). I don't know about the pcb that KT315 send here.

Gate Driver Waveform

Hi all,
I checked the gate drive...(Voltage is from source to gate)
I think it is not good. How about your gate drive waveform?



Thanks in advance.

can delta pulse work with 6V 4.5A battary.
can this battery drive all components ?
can it cause any problem?

Hi okantex,
I think that could be fine to have 6V battery instead of 12v.
Never tested but think that could be ok...just I see a possible problem on Vgson of mosfet device...
6 volts are not big voltage for a mosfet to be turned fully on but think that would be fine for many types including IRFs.
If I remember well Vgson for most IRFs is around 4volts, but the higher the better.
Another issue is current peak...but cause of inductance of coil in PIs this is not generally speaking a big issue related to Vcc.
You could have problems on op amps supply but can find low voltage types that would be fine if you encounter that.
For cmos and 555 6v are fine for everything.

Good luck.

Best regards,
Max

Hi All.
Delta Pulse don't work with 6V. It has in series with power suply two diodes so the voltage will be 6-1.2=4.8V,very low voltage. If you modify the circuit.... who knows...maybe to work. When the voltage is lower than 9V the detector is unstable and has very low sensitivity.
