Delta Pulse

[Jose]

I want to use the microcontroller instead of LM556 and 4538, please provide good suggestions, I would like to share

If I could be scheduled for the DP, would do the following:
Pulse TX adjustable, varying between 100 and 400 us. 100 to 500 Hz frequency varying
First sample from 15 to 100 us, taken after the end of TX pulse with a pulse width of 50 us.
Second sample taken after the end of the first above shows, varying from 100 to 500 us. with a pulse width of 50 us.

KT315 Hello, Hammerhead PI and delta pulse which is better

they are different detectors for different aims. you have to have both in your establishment. after HH you will get all trial and any PI will be for you
VERY EASY to grasp. DP is also simple for to do. mohhandes made it easily, while he is not yet able to finish White's IDX and 'bulgarian' Pulse Star.

mrmetal, 12v is standart power supply voltage for majority PI detectors' schematics. slight bias -/+ 0,5V is justifiably. you can use 12,6V.
with impulse STEP-UP converter you will get hard +12V in the project. I buy them in ebay for low price.
Liu Den, yes certainly you can take a data from the diagram. good suggestions are perhaps to learn another schematics with PIC and ATMEL micro
and take ready soliutions from them. for example you can take solution from Carl Moreland's Hammerhead-PI detector on PIC based.
consider that DVD-ROM has 3GB archive with all schematics and schemotechniKs. in other folders concentrated all information.

good luck

analog schemotechniKs is not dead and still alive =)

special thanks to KT315 for share all detail of DP.
KT315 in maximum power signal(maximum Ton),dp how many need current?
for power supplay 12v is better or 12.6 or ...?

this is a English forum you must use it to get help from nice people here. use google translate for your question.for your question you need to measure frequency for first stage and flow a pdf manual written by kt315 for first step to adjust just type deltpulse in 4shared you will find this manual

mohandes, leave this topic. bulgarian pulse star still waits your involving - no your posting there from 2013 year.
anotherway you will burn your dp evermore.

dear KT , ready i want use your changing in DP2 , and just these caps make for me problem.
i wait for your best deeper detector , and i believe you can finish it.
regards and sorry me.

i find it
when i connect to lf357 and DA3 red led on and 41418 , VD8 and9 burn.
so where is wrong.

Some comments on my experience with Delta Pulse, I can be wrong or not, but maybe someone will find it useful.
Coil Shield for 1X1 mts.? , If you can use.
How to do it?. I do not know, try tape Scocht No. 24 and did not work.
Blinage in the coils is necessary 1X1 mtrs.?.
It is recommended that coils, weighing less than 20 or 25 microseconds delay be shielded, but coils 1X1 mtrs, generally have a greater than 30 microseconds delay, so it would not be practical in my opinion, shielding these coils.
Minimum time delay, in the Delta Pulse.
You can decrease the time delay making modifications as mentioned in the previous post by KT315, but the minimum you can get is about 17 to 18 microseconds, the issues related to the design of the front of the DP, so I not convenient to use between the MOS and diode the coil, as the main advantage of this diode, is annular MOSFET stray capacitance.
Instead, this dido produces voltage drop, which can affect the power supplied to the coil.
Coil resistance.
The resistance of the coil, with its inductance affects the current flowing through it.
High currents in the coil, producing surges that are difficult to adequately cushion, DP accordingly, becomes unstable.
So I think the coils in the DP should not be lower than 3 ohm resistors, including cable.

Taking into account what you wrote in #2636, if that is accurate I think your pulse width needs to be ~300us. Using 90us would be a waste of time.

dear friend i use selector and i can use 155mks , 180mks , 203mks , 235mks , 275mks . i use 130hz for 1*1coil and 500hz for 45*45 or lower than this size.
i ask many time this question , can i use shielding for 1*1m coil ? YES OR NO ?
IF yes ?
1- i use TENUOUS FOIL
2- i use tinned copper
AND i use 12volt regulator for fix voltage , and it product 11.88v .
regards

edit : dear KT315 i add 22mik tnt caps but red LED on and 4148 burn.
i check again , regards

use two mode frequency in 500 and 130hz .PW at 90mks to 270mks .
