ultrasonic capacitor inductance
Now i Can not send any circuit but I´ll do it. I am going to base my proyect in Doppler echos. I am looking another proyect, and I can do it like they do with humans.
rf tank circuit amplifier
ok;I will try to learn something more about LC,it seems very interesting!!. With my proyect I am using ultrasounds of 40Khz, in datasheets put that my recepctor has a narrow band(around 40Khz) I dónt think that woll be a lot of problems. I am trying to get sounds of...
tunned amplifiers
You explained very goog.Thanks you.I suppose that with a similar circuit you can make a small radio,d´ont you?Well, and I have another little dougbt, you explainde the capacitor and the inductor that are in the collector. why is used the capacitor of 1nF and why the values of...
tuning tank circuit
This is the fist step in a reception of ultrasound. I do not know how analize this circuit. I need something similar to my proyect, I want to demodulate sounds for a ultrasound wave.
Added after 2 minutes:
this is the circuit ,sorry
Heloo I am doing a proyect and I d´ont know how to work with RF tuning amplifier. I woould be pleased ijf anyone help me.(give me some information or a web)
hello I am so interested in your proyect. I have a very similar proyect to yours, but instead of sensing human blood I have to Know if an embryo of a CHICK inside the egg is alive. I am trying with IR but I think that with ultrasound will be better, With th beat of the samall animal,Will I be...
ok,i am going to try with ultrasound, now I am sure that ir pass throught the egg but i can not see any change,so let see if i am able to do it with ultrasound;do you know some emitter with 555?Tahnk you
and how?i tried also with ultrasounds, but I can´t see any change at the signal when it pass thought the egg.Are you sure?ultrasounds are used in distance of about 2-3meters!
working of photodiodes
Hi!
I would like to know if the infrared light of a led would pass through CaCO3. I would like to "see" the inside of an egg and CaCO3 is the basic compound. I am trying to make a special pulsometer for eggs(with a little embryo inside). Do you think it is able using...

Thanks

I dónt think hemon its a good ECG. I did it with a photodiode instead of the orp that appears in the circuit and it does´nt work, it have too noise and you do not detect the pulse you detect small movements of your finger. I think this one work better.
photodiode pic micro schematic
Hello, i a m new here and sorry for my bad english. i am in this web because i am trying to do a heartbeat monito but instead of sensing human heartbeats i am trying to sense chick´s beats inside an egg. I am trying to do it with photdiode and infrared(i am using...
