Bulgarian 'PULSE STAR' (... close to Legendary one)

[Qiaozhi]

我已经做好了脉冲星，但识别并不是非常好,电路中有非常多要改动的地方，我可以给大家一些解答

Pulsar circuit forums have very many mistakes, the first power supply circuit, power supply schematic diagram is wrong, wrong magnification of preamplifier, in accordance with the drawings to do, the machine is very unstable, next is the parameter delay part is wrong, part identification to a very strong signal recognition, indicating lamp will light up. Is a big defect, I'm very sorry, English is not good, use Chinese Translation

Congratulations ONE JUST LISTEN wants to help..
Well DP start from power supply,indicate to what the errors.expects YOU

[g.s]

SCHEMATIC you have with corrected the mistakes??.

[kt315]

draw your found mistakes on this schematic.

hi Georgi
now i want complete this. just tell me this pcb is ok , or no .
regards
or any one can help me

Hi, mohandes. This PCB is not my design , I do not know there mistakes. Sorry.

Hi, mohandes. This PCB is not my design , I do not know there mistakes. Sorry.

hi
i finish this detector but i design very bad PCB . i get all value of voltage so my friend where you find the mistake of the voltage ???
just hard adjusting . have very multi turn in integrated part and hard to set it, when adjusting and next change Delay volume all TP point changes, so certain for me the main adjust .
and about LED and disc part maybe my design have fault because i get all wave in scope like timing and PW and P.P.s . just hardly part in TP point.

So i want start again , need good PCB and correct , so if any one design or have link put it here.
i design all parts in proteus program but hard to design PCB , if dont any one help i have to make it.

regards.

My Chinese friend i told you before , if possible please put you Design here.

Good evening sir georgi.q.zhelev I want to ask YOU if YOU schematic work normally.
why has enter here WRONG schematic from other users ???..
Publish a video in table WORK which appears the board star pulse operation with a typical coil for to look work finally THIS pi ..
Thank you g.s

in principle. the first is WRONG the pin at lm 2940.

hi to all ، what is advantage of pulse star over delta pulse which is more easier to build

dose pulse star get more depth ?

[sinclairuser]

there is no advantage over delta pulse, the pulsestar has fundamental flaws that noone seems able or willing to highlight.
forget this and build one of kt315's deltas an excellent project.

[kt315]

thank you Sinclairuser. in near time I will do a small coil and make some testing videos (a coil had went be sold with last delta).
both PS and DP use one principle, DP has more PULSE WIDTH max, 500us, PS has 400us max (BULGARIAN PS, I mean, not another PS we know nothing about), seems there is not so principially difference in depth...

[fengzhai01]

The correct power

I have the perception that lm7905 should be lm 7910..and are modulators as figure 2..
