KT315 Congratulations. and thanks. Delta Pulse pcb. I run.
13 cm coil from 38 cm distance. Detects 2.5 cm money

ahaha! i'm shocked Tufa... YOU DID IT GUY. congrats. glad that somebody got a result.
certainly DP is not for working with small coil, but if you want just work with small coil you can retune schematic.
it is not big problem.

no. The small coil is only for experiment in the workshop environment. I have a coil of 50 cm and 100x100 cm

ok. also i do not see a shielding inside the housing under the board. you also have to shield pots' cases by naked wire. this wire has to be connected to
point on the board SHIELD. look pics in my albums how to do.

Hi KT315, I have a simple question about the delta pulse supply voltage.
The delta pulse circuit operates from a 12 volt supply and uses a simple op amp rail splitter to make the + and - 5 volt supply.

How low can the 12 volt battery voltage get before the circuit starts to fail and not work properly ?
thanks

[kt315]

hi 666 Guru

you had answered on your question. + and - 5 volt supply (critical for the op amps) plus 2V on diodes gives you 12V.
so 12V is critical value. 10-11V is an edge of fail. i tune voltage indicator on 11.5-11.6V.
thanks

Hi KT315, thanks for the answers, its better to have real world information, than my theory, cheers.
