Hi all This is my first thread in the forum. I make the changes contained in the scheme, in another forum, to improve stability, reduce the delay time, etc.. , Is oriented mainly to the use of rolls of 45 x 45 or less and is the scheme that utizo detectors in my DP. Try to explain: R6 1K, I used 1.5 k, that improves stability and allows better tailor damping resistance, also allows use of lower inductance coils. T2 open collector. Allows adjustment of the contol softer delay, this circuit which apparently prevents overloading of the front, it is proved necessary, when using coils medium (45 X45 or less). Automatic or manual control, a simple tap connects to terminal 3 of the virtual mass U7A. I think the manual is better to experiment with the set-point of the detector. The automatic mode can be confusing. Other changes around the entire time base, to reduce the delay time, when using fast coils. Also the frequency is 550 Hz for rolls up to 45x45. Instead of common speaker of 8 ohms, I use a 600 ohm telephone capsule giving a good level of audio, low power consumption. Sorry for my bad English regards Jose, The Legendary

Hello Legendary
good for make the changes
  please put your results with  coil  45 x 45 show that the difference obtained by  these changes

best time

Hello Japanese DP is generally difficult to adjust and requires higher inductance coils of other PI. In my personal opinion, the front of the delta pulse, is overreaching.  R6 adjusted to 1.5 K, greater stability is obtained and is easier adaptation to different lower inductance coils; thus improving stability. The sensitivity, virtually not affected or is compensated by capturing less noise. It also improves the response to small objects. Decreases up to 18 usec delay. Approximately, depending on the construction of the coil. It is also easier to adjust the damping resistance. The maximum sensitivity in the air to a 45X45 coil, under ideal conditions, is about 40 cm for a bronze coin 25 mm. In diameter and 90 cm. for a can of coke of 333 cm3. It also influences the design of the PCB, I use those published in the forum, but I realize bridges on the ski tracks GND and power "+ E" and "-E" to improve stability and reduce noise. Also short and shielded cable connections between the PCB and coil connector help reduce noise. I do not know if I chose the right path in these changes, but for now all my "DP", use this setting and I am satisfied with the results. My coils are made ​​with CAT 5 cable and Scotch tape No. 24 to the shield. A Warm Welcome

Hello Legendary

-your results improved for  a bronze coin 25 mm by 10 ~15cm.(its goog)
                                      - for a can of coke of 333 cm3 the same .
-Its  improved the response to small objects only.

-generally difficult to adjust A result of the Virtual GND=D6A as its currency and that  i   does not understand what u worked in this direction!
-You have the right to be  proud with,Depending on what you like to search for.
-Thanks for replay.

best time

j.

Hello Supermen Sorry if I misspoke. The changes are in red color scheme. The IC, are the same as those in the original scheme. Excuse my bad English. Best Regards

I know I have fully read! I made many tests under various schemes of the forums but unfortunately there is no improvement. I think the secret to success is the quality and signs of components! But nobody wants to reveal the secret for best results! This post has asked for that reason . On a forum that openly told me. . Exhausted
