hi albbg,
thanks for your input, have tested as you said, on the introduction of 6.8k in series to the probe the threshold voltage have set to 2v. but i still hear a low volume of buzzer when checking continuity across capacitors. also have noticed on powered up the circuit i see 1v in gate of...
hi KlausST,
short circuit i meant was , it shows continuity always when i probe in my test board, whereas the branded multimeter in continuity mode didnt show any continuity. the probe i mentioned in the diagram is where i soldered the multimeter probe for testing boards.
thanks

Hi guys,
Im trying to make a continuity tester as an alternate for multimeter continuity tester. Im facing a issue, that it shows a short circuit in all conditions. The schematics for the tester have been attached.
i have powered the circuit from USB ( +5V ). Is my circuit correct?
hi
these will help you out

hi,
the cap in series with speaker is 100uf which a too large capacitance. placing capacitors in series in audio circuits is to eliminate any undesired dc signal. replace it by 33pf or 1nf ceramic cap or just remove it and check.
hi,
im working in a project , which has hdmi video signal. For hardware interfacing with a processor, what to do with the utility and hot plug pins? should i leave it not connected or should i pull it up or down?
thanks
Hi,
Is there any difference between electricity and current? current is the flow of electrons under the influence of electric field from higher to lower potential. but electricity?
thanks
Hi
Check the voltage of the power bank by connecting it to a mobile. also verify the charge level of the batteries. In such cases if the power bank batteries are at low charge the output wont be stable as you( marvins42 ) have mentioned.
hi,
can anyone explain or share web link about decibel? I cant able to understand it clearly. also what to know about 3db line mentioned in all graphs.
thank you
hi,
I would like to know what is the audio input positive and negative signal in general, also will it work if i interface the audio signal from mobile phone ( 3.5mm jack ) to the left and right positive pins and grounding the negative pins?
please find the attached image.
thankyou
