Hi great video. May I know if you have made an improvement on the circuit to reduce audio issue? and im thinking of upgrading the circuit and use neural network to make a simple diagnosis of diseases. Can you perhaps make a video for it or give any recommendation for the upgrade? Thanks.

Interesting but I want to add more sensitivity to the microphone by increasing the dB adjustable by potentiometer. I need it to hear sounds, voices in contact with surfaces (walls, metals, wood, etc). Let me know. Thank you very much.

I can't remember the exact component - I believe the diameter may have been around 10 mm.

How to add volume control? how to increase power? The class b amplifier has zero crossing deformation. how to correct this?

Hmmm, well volume control could probably be added using a potentiometer later in the circuit. I am actually still trying to work out a new circuit for this so that it is more consistent and has less audio issues. Hope I can get it working soon.

More projects are found at HTM-Workshop.com Note: I used pin 3 as the ground and pin 2 as my incoming signal - the schematic in the beginning shows these two switched. If you are looking for similar equipment to use Milwaukee (without thermocouple) - amzn.to/37lJBT6 Best Wire Cutters - amzn.to/3xbgf4v Function generator - amzn.to/38yEuj3 200 MHz Digital Oscilloscope 2 Channels, Grey - amzn.to/3x0KTxu

you cna wlays look for a think labs 1 or an eco duo, but if you arel ookign for a cheaper solution, i am not really sure other than making an electoprnic stethoscope that also supports your eharing aids, but he stethosocpes i mentioned work for hearing aiods, and also, my girlfirend is also deaf and hard of eharing she uses a think labs 1 , she also has a littmann 3000 and a littmann 3200 stethoscope, hope this helps, :) @@MajidKhan-hx8uh

Check the link for the schematic I have used - it needs a couple corrections so check the comments in reddit for the corrections www.reddit.com/r/diyelectronics/comments/opl629/electronic_stethoscope_audio_amplifier_but_we_did/?context=3

Please kilohm is pronounced kilohm, not kil-a-ohm. Yes it matters. It has been around longer than you and I have been alive - show it some respect.
