Delta Pulse

[mazari]

thank you very much mr kt315.please can you give me the (shematics +pcb for new board that you post .it seems to me easier tham i'm working on.

This is the second time that Ibuilt this board but it didn't work it cost so much in vain.

see clipped 'delta' impulse on output of opamp, LF357, by o-scope.

maybe you need connect a coil?

with magical surahs from holy Quran on your lips you can find gold without the cat and Delta Pulse.

thank you mr k315.but when i connect a coil irf 840 getting very hot .what is wrong?

schema new

What's new in the scheme? Two LEDs are united in one double. I do not see another new one.

[kt315]

the schematic is same left. new -

-- you can set 2 LEDs or bicolor one
-- sockets were changed on another 'pops screw style' type http://www.ebay.com/itm/50pcs-2pins-...gAAOSwpLNX~Lut
-- grid poligons, cause was hard to desolder in some places
-- transistors' position in voltage indicator was fixed
-- general optimization

Does anyone have a listing or diagram of Delta / Sniffer trouble shooting test points with nominal expected voltages ?
